The invention relates to a product for packaging a food product comprising an agent that improves the color, food packaging and packaging methods of the food in said packages.
The color of meat is an important characteristic of the meat, which affects its suitability for sale. Buyers often use color as a measure of quality and freshness of meat. The color of the meat is flowing with the amount and the chemical state of myoglobin in the muscle. Myoglobin is found in the muscle tissue of allanimals and its function is to store and sufficient oxygen through the circular binding molecular oxygen with the creation of an intracellular oxygen source for mitochondria. Pork and poultry meat usually contain a smaller amount of myoglobin than beef and , consequently, they are lighter in color than beef.
Myoglobin involves a binder open site called a hemoma that can bind the indicated small molecules, for example, molecular oxygen (O2 or "oxygen") or water. Myoglobin does not affect the molecule associated with hemea The site and the type of linked ligands near the site of myoglobin binding may lead to a change in the color of the myoglobin.The color of the meat product will be changed based on the amount of available myoglobin, as well as the number and type (types) of the Lyndon Mollet The mole (molecule) associated with the hemoconjugation site, molecular oxygen, acts as a ligand, which is bound to the heme group, providing a biological transfer of oxygen from the blood stream to the mitochondria inside the cell. When oxygen is included in the heme, purple deoxyhemoglobin becomes an oxymoglobin, distinguished by red color. When a molecule of water is linked to the hemoglobin, the myoglobin molecule is brown and it is called methymogon. Relationship with carbon monoxide (CO) can lead to a red color similar to that obtained by the connection with oxygen.
Nitric oxide (NO) forms a persistent pink color of the meat-brine.
Historically, fresh meat products intended for buyers are cooked and packaged for final use, in fact, on the spot of sales. Packaging of the product, which ensures the preservation of the desired color of freshmeats, can promote the suitability and appetite of meat products for buyers. Existing technology of packaging meat can, from different sources, not ensure the preservation of its color, which meets the requirements. The usual packaging method used by retailers for fresh meat is to stretch a thin plastic film around the foil that supports the product. The film penetrates the kis-em, so the color of the meat quickly becomes bright black. However, during storage, the color will remain bright red for only about three days. So, this method of packaging is undesirable, because the color often becomes unacceptable before the meat can be shown or sold, although it remains nutritious and safe to use. As a result, to perform centralized patching operations, trying to create a packaging method that will keep the color of fresh m For a longer period of time. As an option, the meat is packed in vacuum mixes that prevent the penetration of oxygen, which are sealed by creating a vacuum and which prevent the contact of oxygen with meat, until the packaging will not be opened. Reduced meat vacuum products are useful, safe and have a long shelf life, but in consequence they can get unwanted pulp of meat in a package that does not provide the desired red color until the m ' Iso will not be exposed to air. The buyer pays off to meat that has a purple color in less than red meat. In order to provide red color, which is preferred by pork-horses, meat is also packed in packaging with a changeable atmosphere ("MAP"), while meat is stored in sealed packaging containing an atm-mosphere, which differs from air surrounding the environment. For example, one of those available to acquire IDA has an atmosphere, which is different from the air surrounding the environment. For example, one of those available to acquire IDA has an atmosphere, which is different from the air surrounding the environment. For example, one of those available to acquire IDA has an atmosphere,
11

12
enriched with oxygen (up to 80% volume) to better preserve the predominantly red color. In one case, the MAP contains meat in carbon dioxide with a very low oxygen content without doses until the show, when the meat is subjected to oxygen to obtain the desired red color. Alternatively, the meat can contact the IDA, and the one that has such an atmosphere, containing a small concentration of carbon monoxide (CO) (for example, 0.4% of volume) to preserve the predominant red color of the meat. However, although IDAs that contain CMs can provide a shelf life comparable with the storage period of meat packaged with the help of vacuum, the red color, created by the presence of CO, may be perceived as "unnatural" bright redcolor . In addition, there is a tendency towards the spread of red color, created by the CO, a significant part of the meat product, which leads to long-term "pinkness" of the inner part of the muscle, which may remain even after the meat is completely subjected to heat treatment. The bright red complex of CO-myoglobin is called carboxymio gobin. The presence of carbon monoxide may also adversely affect the volume of sales to mAr buyers containing CO.
IDAs also need a free space for the product to contact the modified atmosphere with the surface of the meat to influence them to provide the desired color for a specified time. Such a requirement for the free space over the product leads to an increase in packaging volume, increases the cost of transport and storage requirements, and also restricts the ability to display the appearance of the product, making it less visible due to the high side walls of the container and the gap between the film and surface of the meat.
Necessary packaging products that store an unfavorable color of meat, ensuring that the necessary or increased shelf-life and freshness of meat.
For the salting of meat, non-tritium or nitrate salts are often used, for example, sodium nitrite, and they can also affect the color of meat. TNI nitro and nitrate impurities generally considered bezpech-tion for use in food, andthey are well-known preservatives, Use-tovuvanymy in the salinity of yakokorok products, sausages, bologna sausage and "hot dogs". Nitrates and nitrites are used in the meatindustry for salting and disinfection of meat products, often in the process of providing red color resistant to pink color. For example, in the document UK UK 2187081Areated immersion of meat in aqueous solution of sodium chloride, as well as the effect of ions of polyphosphate and ion on nitrite to preserve meat.

reactors or continuous reactors, processes using a suspension, a solution and a pseudo-liquefied layer, one or more catalysts, including; for example, heterogeneous and homogeneous systems, as well as catalysts 2Ideg, RNIIiRs, me-talocenes, and single catalysts with limited geometry for the creation of polymers with different combinations of properties. Such polymers may be sufficiently branched or actually linear, with their branching, degree of dispersity and average molecular weight may vary depending on the parameters and methods selected for their manufacture in accordance with the techniques used in the industries concerned with the creation polymers
"Polyethylene" is the name of the polymer, the base stream of which differs by the chain - (CH2-CH2-) n. The polyethylene homopolymer is usually described as a solid having a partially amorphous phase and partially crystalline phase with a density of 0.915-0.970 g / cm<sup>3</sup>. The relative crystallinity of polyethylene, as is known, affects its physical properties. The amorphous phase provides flexibility and high impact strength, while the crystalline phase provides a high temperature of softening and hardness.
The unmodified polyethylene usually assumes a high density gomopolymer, with its crystallinity of 70-90%, and the density is close to 0.96-0.97 g / cm<sup>3</sup>. Polyethylenes, the largest of which are commercially available, are not an unchanged homopolymer and instead have an alkyl group of C2-C8, attached to the main chain. These substituted polyethylenes are also known as branched chain polyethylene. In addition, commercially available polyethylenes often include other substitution groups, created by co-polymerization. Branching with alkali groups usually reduces the crystallinity, density and melting point. The density of polyethylene is closely related to the crystallinity. On the physical properties of commercially available polyethylenes are alsoaffected by the average molecular weight and distributionmolecular weight, the length of branches and type ofowners.
Qualified specialists in the art usually relate to "polyethylene" several large catheter polymers and copolymers. The location of a specific polymer in one of these categories, polyethylene, is often based on the density of "polyethylene", and also often determined by an additional reference to the method by which it was made, since the method often determines the degree of branching , crystallinity and density.In general, the used nomenclature is not specific to the compound, and instead, this refers to the range of compositions.This range zones often include both homopolymers and copolymers.
For example, high-density polyethylene (HYPE), which is commonly used in engineering, can be attributed to (a) homopolymers whose density ranges from 0.960 to 0.970 g / cm<sup>3</sup>, and (e) to copolymers of ethylene and alpha-olefin (usually 1-butenabo-1-hexene) having a density of 0.940-0.958 g / cm<sup>3</sup>. HYPE includes manufacturing polymers
with the help of catalysts of type 2Idigor orRIIiIrz, and also include "polyethylenes" with high molecular weight. The opposite is HYPE, polymeric. the chain of which has some branching, are "polyethylenes with ultra-high molecular weight", which are essentially non-isolated specific polymers with a significantly higher molar mass than HYPE, which has a highmolecular mass.
Below, the term "polyethylene" will be used (unless otherwise specified) to indicate ethylene homopolymers and ethylene copolymers of olefins, and this term will be used without taking into account the presence or absence of substituent groups of the branching.
Another broad group of polyethylene is "polyethylene high pressure and low density" (Ι_ΡΡΕ). This formulation is used for the indicated branched homopolymers, whose density is 0.915-0.930 g / cm<sup>3</sup>. ΙΙΡΕ usually contain long branches of the main chain (which is often called the "spine") with alkyl substitutions from 2 to 8 carbon atoms or more.
Low density linear polyethylenes (ΙΙΙΡΡ) are copolymers of ethylene and alpha-olefin having a density of 0.915 to 0.940 g / cm<sup>3</sup>. The alpha olefin used is usually 1-butene, 1-hexene or 1-octene, in which, as a rule, a catalyst is used for the catalyst 2Ieed (although for the production of II-IIPE, which has a density from the higher end of the range, catalysts are also used, and for the other well-known catalysts Various variants of such polyethylene also use metallocene and other types of catalysts).
The copolymers of ethylene and α-olefin are copolymers containing ethylene as a major component that is copolymerized with one or more alpha-olefins, for example octen-1, hexen-1 or butene-1 as a minor component. EOAs include polymers known as ΙΙΙΙΡΕ, ν_YΡΕ, ΙΧΡΕ, as well as plastomeres, and may be manufactured using various methods and catalysts, including meta-lecenins, single-site catalysts with limited geometry, as well as catalysts 2Iedium-Maya and IRIriIz.
Polyethylene of fairly low density (ν__ΡΕ), also called "low-density polyethylene" (υ__ΡΕ), contains ethylene copolymers of α-olefins, usually 1-butene, 1-hexene, or 1-octene, while skilled specialists in this gaseous meadow view it as one having a high degree of linearity of a structure with a short branching, and not a longitudinal characteristic of the branches of ΙΙΡΕ. However, ν__YΡΕ have a lower density than Ι_Ι_ΡΡΕ. Qualified specialists in this field believe that the density of vysyp is in the range of 0.860-0.915 g / cm<sup>3</sup>. The method of procuring ν__ΡΕ is described in the European patent document published under number 120503, the text and figures of which are introduced in this document using a reference to it. Sometimes, the density of which is less than 0.900 g / cm<sup>3</sup>, called "plastomers".

Polyethylenes can be used by themselves, in mixtures and / or with copolymers in both single-layer and multilayer films in cases of packaging of food products such as home-made poultry, fresh red meat and processed meat.
The term "modified" herein refers to a chemical derivative, for example, which has any type of function of an anhydride, for example, maleic anhydride, crotonic acid, citraconic acid, itaconic acid, fumaric acid, etc., regardless of whether grafting it to a polymer, copolymerized with a polymer, or otherwise is fussionally linked to one or more polymers, and also includes derivatives of such functional groups as, for example, acids, glassy ethers and metal salts that are obtained with them. Other examples of conventional modifications arepolyolefins, modified with acrylate.
The terms identifying polymers herein, such as "polyamide" or "polypropylene", include not only polymers containing structural units derived from monomers known in the art to polymerize to form a polymer of the specified type but also to sing monomers, as well as unmodified and modified polymers, for example, by obtaining a derivative of a polymer after its polymerization to add functional groups or particles along the polymer chain. In addition, terms that identify p olimers also include "mixtures" of such polymers. Thus, the terms "polyamide polymer" and "nylon polymer" may be referred to a homopolymer containing a polyamide to a copolymer containing polyamide or mixtures thereof.
The term "polyamide" refers to a polymer having a highmolecular mass having amide bonds (-OPNN-) π that are located along the molecular chain and includes nylon polymers that are known to be well-known polymers, used in many cases , including their use as packaging films, bags and boxes. See, for example, "Encyclopedia of Modern Plastics," 88, vol. 64, 10A, pp.34-37 and 554-555 (MsOgam-NIIІ, IPS. , 1987), introduced here with the help of a reference to it. Polyamides are preferably derived from nylon compounds approved for use in the manufacture of products intended for the processing of food products, handling of them and its packaging.
Used herein the term "nylon" is precisely used synthetic polyamides, both aliphatic and aromatic, both with a crystalline, and zinc crystalline or amorphous form, which differs by the presence of an amide group -OAnN. It can be attributed both to polyamides, and toposipoliamides.
Thus, the terms "polyamide" or "nylon" are encompassed as polymers containing structural units derived from monomers, for example poly-amine polymerization cap-rollactams, and copolymers obtained by copolymerization of caprolactam with a comonomer, which, when polymerized by itself, does not
to form polyamide. It is preferred that the polymers have been selected from compositions considered safe for the manufacture of products for processing, handling and packaging of food products, for example, zeejelon resins approved by the US Department of Commerce for the supervision of medicinal products and foodstuffs at 21 "The Code of Federal Regulatory Acts", §177.1500 ("Nylon Resins"), which is introduced here by reference to it. Nylon polymer resins for use in the packaging and processing of food products include nylon 66, nylon 610, nylon 66/610, nylon 11, nylon 6, nylon 66T, nylon 612, nylon 12, nylon 6 / 12, nylon 6/69, nylon 46, nylon 6-3-T, nylonMXY-6, nylon MXII, nylon 12T and nylon 6I / 6T are disclosed in the 21st "Code of Federal Regulatory Acts" §177.1500.

When using the phrase "amorphous nylon copper copolymer", the term "amorphous" is used here to indicate the absence of the correct three-dimensional arrangement of molecules or subcorporates of molecules passing at distances that are significant in relation to atomic proportions. However, the orderingstructure can exist on a local scale. See. "Amorphous polymers", Encyclopedia of Science and Technology of Polymers, 2nd Edition, pp.789-842 (TmiIeuu & Sop5, Ips., 1985). In particular, the term "amorphous nylon copolymer" refers to material which is qualified in the field of industry Dipere-native scanning calorimetry is considered to be such that it does not have a measurable melting point (less than 0.5 cal / g) or has no melting temperature measured with differential scanning calorimetry, using the instructions AZTM 3417-83 (AZTM-American Society of Materials Testing Experts). Amorphous neelon copolymer can be produced by condensation of hexamethylenediamine, terephthalic acid, and isophthalic acid according to known methods. Amorphous nylons also include such amorphous nylons that are obtained in the reactions of polycondensation of diamines with dicarboxylic acids. For example, aliphatic diamines combine with aromatic dicarboxylic acids, or aromatic diamines combine with which are obtained in the reactions of polycondensation of diamines with dicarboxylic acids. For example, aliphatic diamines combine with aromatic dicarboxylic acids, or aromatic diamines combine with which are obtained in the reactions of polycondensation of diamines with dicarboxylic acids. For example, aliphatic diamines combine with aromatic dicarboxylic acids, or aromatic diamines combine with
21

22
aliphatic dicarboxylic acid in order to obtain acceptable amorphous nylons.
Used here, the name "Eunon" refers to the co-polymer of ethylene and vinyl alcohol. BUN is also known as saponified or hydrolyzed ethylene and vinyl alcohol co-polymer, and is concerned with copolymer with vinyl alcohol having an ethylenic comonomer. Eunon is obtained by hydrolysis (or saponification) of copolymer-ethylene and vinyl acetate. The degree of hydrolysis predominates from about 50 to 100% of the molar composition, more preferably from about 85 to 100% of the molar composition, and most preferably of at least 97%. It is well-known as a fairly elegant barrier for oxygen, with hydrolysis-saponification to be performed almost completely, that is, their degree should be at least 97%. Eun is available in the form of resins with different percentages of ethylene, and there is a direct relationship between the content of ethylene and the point of smelting. For example, in the event that Euon has a melting point of about 175 ° C or less, then it characterizes the EuO materials, which contain about 38% of the molar composition or more. Euon, the ethylene content of which makes up 38% of the molar composition, has a melting point of about 175 ° C. With increasing ethylene content, the melting point decreases. In addition, poly-meres Euon, having an increased molar percent of ethylene, have increased gas permeability. The melting point of about 158 ° C will affect the content of ethylene, about 48% of the molarcomposition. Also, Euon copper mines having lowered or elevated ethylene content can be used. It should be assumed that with increased content the processing and orientation will be lightened, but the gas permeability, in particular, relative to oxygen, may become undesirable in certain cases of packaging, which susceptible adult microbes in the presence of oxygen. On the contrary, reduced content can provide reduced gas permeability, but the feasibility of processing and orientation will be more complicated.
As used herein, the term "complex polyether" refers to synthetic homopolymers and co-polymers that contain essential bonds between monomer elements that can be formed using polycondensation methods. The polymeric type is preferably an aromatic complex polyester, and more preferably homopolymers and copolymers of polyethylene terephthalate, polyethylene oleophthalate, polybutylene terephthalate, polyethylene naphthalate, and mixtures thereof. Suitable aromatic polyesters may have a specific viscosity of 0.60-1.0, and preferably 0.60-0.80.
The phrase "atmosphere with reduced oxygen content", if it concerns a packaged product, implies a reduction of the partial pressure of oxygen in contact with the packaged meat product, compared with the partial oxygen content of the atmosphere in the Earth at standard temperature and pressure at sea level. Packages with a reduced oxygen content may include packaging with an altered atmosphere in which the partial pressure of the titanium dioxide is lower than the partial pressure of the Ze-
ml at standard temperatures and pressures at the level of the juice, or vacuum packages with a minimum pressure gas in contact with the packed meat som. In a package with a changed atmosphere, an environment with a significantly reduced oxygen content may be created, and it is desirable that the oxygen content in it is less than 3.0% and less than 1.0%. In the case of processed meat, it is desirable that the oxygen content in the volume is less than 0,5%.
The phrase "vacuum packaging" refers to packaging, in which the active removal of the contents inside the package of atmospheric gases, the precise oxygen and the sealing of the packaging are carried out in such a way that the gas present from the outside of the package could not actually penetrate it. As a result, there will be a packaging with the minimum amount of oxygen remaining in contact with the meat contained within the package. Removal of oxygen from the environment directly surrounding the product, slows down the processes of destruction caused by bacteria and oxidation, thereby allowing keeping meat in a more fresh form for a longer period of time.
"IDA" is the abbreviation "packaging with changedatmosphere". This is such a form of packaging, in the case that in the free space of packaging over the product before the release of its seal gas is actively supplied. Of course, the gas is changed so that it differs from that gas, which is in the normal state in the earth's atmosphere. As a result, they receive a package with a significant amount of gas surrounding the visible surface of the product inside the package. To effectively extend the shelf life, an MAP may be used, intended for fresh meat, which is eitherobricated with oxygen, or has an atmosphere that does not contain oxygen.
"RAR" is the abbreviation "packaging with less atmospheric content". It may be in the form of a MAP in which atmospheric gases are in a minimum quantity, so that the packaging material enters physical contact with the inner contents. RAR, however, may also be a form of vacuum packaging, in which case the atmosphere is not completely retrieved from the inside of the package. Examples include an unusual packaging for fresh meat, such as a "tray wrapped with polyvinyl chloride, spatula-lean", as well as conventional packaging for home-made fiber-optics in the form of a finished shell, when the film is rolled up or the bag is sealed hermetically around the meat tray . Of course, fresh meat has a higher profile than a tray used to hold meat, so that the packaging-on the film surrounding the product,
The phrase "package for the buyer" refers to some sort of container in which the product is contained, in order to display and sell it to householders who are householders.
The phrase "cooked in the shell" refers to the meat packaged and / or marketed in a centralized place, intended for the buyer, and delivered to the market for retail, in such a way that it is easy to use immediately show and
23
96258
24
sell. Package in the form of a finished shell actively continues the storage of fresh meatproduct with the required quality, to provide additional time that takes its packaging in the centralized equipment, delivery to the seller, which engages in retail trade, and furtherdemonstration in the illumination for the selection and purchase of the beetle.
The phrase "improving the color of the myoglobin" refers to any agent (or its precursor) that interacts with or interacts with any structure containing myoglobin (including deoximiglobin, oxymioglin, methymogolbin, carboxymioglobin and oxide-nitrogen myoglobin, but not limited to), whose natural properties are unaltered, found in fresh meat products, to create or preserve the desired color, for example, red, indicating the flesh of the meat. The agent that improves the color of the myoglobin may also interact or interact with the hemoglobin contained in the meat product to provide, maintain or enhance, that is, "fix" the desired color. Thus, the agent that improves the color of the myoglobin, is not a color additive, but acts as a color fixer. Examples of Agents
The term "deoxymioglobin" refers to myoglobin, which contains oxygen in the gem. Atom iron gem is in a state of reduced iron. Theoretically, the molecule of water in the liquid state is a ligand, included in the gem. Deochemioglobin is associated with a non-coated and inflamed pulp pigment of fresh meat.
The term "oxymioglotin" refers to a saturatedoxygen form of deoxymioglobin, wherein the hemoglobin ligation is a molecule of gaseous oxygen. Oxy-myoglobin is associated with a pig of red flaxseed meal.
The term "metmioglobin" refers to an oxidized form of myoglobin, in which iron is found at the onset of an oxidized iron. Methyloglobin can be formed when oxygen leaves heme of oxime-globin and takes away an electron, leaving an iron atom in the state of oxidized iron. Methio-globin leads to the formation of a characteristic oxidized brown pigment of fresh meat.
The term "carboxy moglobin" refers to a reduced form that does not alter the natural properties of a carboxylated deoxymeglucose pigment, in which the hemoglobin lactate is an oxide. Carboxy myoglobin has a red color.
The term "nitroxymioglobin" is a relative form of nitrosated deoxyhemoglobinpigment with unchanged natural properties. The ligand of the heme is a molecule of zakis and nitrogen (N0). Nitrous oxide is also called oxide. Nitroxmioglobin, among other things, is also called oxide-nitrogen myoglobin, nitrosogem-romagen or nitrosomioglobin. Nitroxiomyog-lobin has the same red color as oksiimiogobin and carboximeoglobin.
"Oxide-nitrogen metmioglobin" is a
oxidized form of deoxymeoglobin with unchanged
natural properties when there is a nit-
rhythm It is used to describe the brown
the color of the meat that usually takes place after
tion of nitrite during the canning process.
The term "nitrozogamochrome" refers to nitrozoate protoporphyrin (heme complex), separated from the protein component of globin, myoglobin molecule. Nitrozogamochrome provides a steady rosy tint of reddish brown color of the finished meat, which has undergone a conservation treatment, with the iron heme is in an updated state.
The term "meat" or "meat product" refers to any tissue of livestock containing myoglobin or hemoglobin, for example, beef, pork, veal, lamb, lamb, chicken meat or wild boar, wild game meat, for example, venison , quail meat and duck, fish, fish products or sea products. Meat can have a varied form, including varietal cut, sub sorte cut, retail cut, as well as<sub>:</sub> minced meat, crushed or mixed form. Meat or meat product is mainly fresh raw, not heat treated meat, but it can also be frozen, strongly cooled or defrosted. In addition, it should be assumed that the meat may be subjected to other types of processing, such as radiation treatment, biological, chemical or physical processing. The suitability of any particular of such treatments may be determined without excessive experimentation in the light of what is disclosed herein. Since the agent that improves the color of the myoglobin is effective in promoting the desired color, its development, enhancement or preservation, it can safely be used for this purpose. It is desirable that the period of the meat after slaughter was less than 20 days. More preferably, the post-graft time is less than 12 days or even 6 days,
Various meat cuttings are also called opto-cutting cuttings, both terms refer to the larger parts of the carcasses that are usually sold and / or delivered to butchers who perform further separation of the part of the small part of the part and into individual pieces for retail roses -collection for sale to buyers. The following examples of varietal disassembly are possible: the femur of the beef carcass, the back-end time, the lumbar, the cortex, the short philea, the breast, the rib, the anterior part, the go-throat and the cervical part. Examples of varieties of pork picking include the dorsal part, the ham, the leg ham, the front ham and the breast, the bait for re-sorting are intermediate in size and can be further divided into pieces for retail sale, or sometimes they are sold as shredders for retail sale .; Beef, Obtained by repartition, includes the front leg, ribs, bacon, flesh of the upper part of the beef thigh, the pulp of the lower part of the femur, the upper thick edge of the lateral fold, the lower thick edge of the lumbar spine, the cut and the upper fillets. The pork, received at the repeated disassembly, includes the shoulder edge of the front pig hams, a picnic, a center-

flax cut, lumbar spine, shoulder blade, skeletal hog and side ridge.
Retail disassembly of meat leads to the receipt of pieces intended for the buyer, whereby they are obtained by separating op-cuts cuttings into smaller pieces. Examples of retail pieces of beef include portions-pieces of flesh, for example, beef femur, flesh of the upper part of the beef hip, slicing in the form of cubes, wicker, t-shaped bone, fillet-time, small fillet, fleshy part of the back, rib part , flap, barrel and apex, meat for baking, for example, from shoulder blade, meat for carving in pots and forehead, breast for salting, fresh lentil, meat for slaughtering, end of ribs, kebab, core beef steak, rounded chicken coop, transverse chops of beetroot, portions or rolls, beef and beef bryketyz. Examples of what is obtained in the retail sorting of pork,
The phrase "fresh meat" means meat that has not been heat treated, canned, smoked and marinated. "Fresh meat" is a meat-and-bone after physical separation, for example, by disassembly, crushing or re-mixing. In fresh meat, not reinforced, there is no added salt. Naturally occurring sodium is less than 50 mg per 100 g of meat, while the amount of existing salt is less than about 0.15 wt.%, And preferably less than 0.128 wt. % Values of sodium are listed in the database for food stuffsmall, which is called "National Bank of data on nutrients", while this is published in the Agricultural Reference No 8 "Composition of Food - Raw, Processed, Cooked", and in this "Directory 8"
The term "reinforced meat" means meat that contains added water to it, mixed with other ingredients, such as sodium chloride, phosphates, antioxidants and flavors, for example, to make the meat moist, more delicate and promote an increase in the time its storage. Fresh chicken, pork or poultry meat after "gain" will usually contain 0.3-0.6 wt. % salt (sodium chloride).
The term "processed meat" refers to meat, whichwere modified by heating or chemical processes, for example, through heatprocessing or canning. Smoked ham, hot dogs and snack meat are a piece of meat processed by canning.
The phrase "non-preserved processed meat products" refers to processed meat products that contain no nitrites or nitrates. Non-preserved processed meat products usually contain more than 1.0 wt. %, and usually 1.2-2.0 wt. % Na-triumide (salt) chloride. Examples of non-preserved
Frozen meat is a beef for roast beef and brother-wool, which have undergone a heat treatment.
The term "canned meat" refers to meat which is stored by direct addition of nitrite (or nitrate that passes into nitrite), and in the presence of at least 50 ppm (molliferous particles) of sodium nitrite and at least 1 weight% added salt, that is, sodium chloride, for the purpose of preservation by slowing the growth of bakteri. In canning compositions usually know nitrates, nitrites or their mixtures together with sodium chloride. "Uncooked meat" does not contain nitrite or nitrate that adds. Meat products, which are preserved in a moist state, are soaked in sunflower seeds of cooked salt. In the case of canned food in dry condition, the salt is applied to the surface. Meat products that can be preserved with the help of an extrusion, contain canned salt (preservative), which are introduced into meat by the needle.
Canned, processed meat products often contain 2-3.5 wt. % salt The content of brine is about 3.5-5.0 wt. % (2.6-3.0 wt.% In processed meat) as a level of sodium chloride or salt (some part, or the whole number of Cs1 can substitute chloride) is needed in processed meat for the desired deceleration of bacterial growth to provide a shelf life of about 60-90 days, although at reduced levels of salt to ensure shelf life can also be used and other means of preservation. According to Redd, R.V.apsi R. ZapiCi, 2000, Nigeya Sigiphode Meia. RooC & Chihiiiiop Rgez, Ips., Tgidiiii, ST, canned mallow may have typical salts, which are approximately 1.2-1.8 wt. % in bacon, 2-3 wt. % in the hole, 1-2 wt. % in sausages and 2-4 wt. % in the dried material. It can be assumed that fresh meat, for example, beef, pork or meat homeoptik, does not contain naturally occurring or added nitrates or nitrites.

In Europe, it was assumed that the minimum level of salts and nitrites required by the law for canning is, respectively, 1.0 wt. % and 50 pounds The Ministry of Agriculture of the United States states: "With regard to the policy that is being carried out, the Ministry of Agriculture requires that all preserved products" kept refrigerated ", the minimum content of nitrite included in them be 120 rubles, if an enterprise can not demonstrate that security will be provided with help

Performing a different prevention process from spoiling, for example, heat treatment, with control at this pH or humidity. Such a guideline that the amount of 120 RPT for incorporated nitrite is based on safety data that was considered in the development of the standard relating to bacon "(See the manual" Rossazizd andPressiogh Saziyahiyop Napbiook " ", Rs. 3, p. 12, reworked in 1995.) In the management, it is stated:" There is no regulatory minimum regarding the level of nitrite included, but can be used nitrite in the amount of 40 RPT, because it carries some canningimpact. This amount is also sufficient to fix the color and to provide the expected appearance of canned meat or poultry. "
Meat product may be any meat, suitable for human consumption, which contains a molecule similar to myoglobin. The reference to the total myoglobin in meat products relates to the number of molecules that are similar to myoglobin that are physiologically present in the meat tissue before the preparation for human consumption. Specific maize-products contain levels of myoglobin, sufficient to provide a characteristic color for them. Tobacco-free pieces of fresh cut meat include beef, veal, pork, poultry, lamb and lamb. In these different types of meat products, the concentration of myoglobin is changing. For example, beef usually contains about 3-20 mg of myoglobin per gram of meat, the pork contains about 1-5 mg of myoglobin per gram of meat, the chicken contains less than about 1 mg of myoglobin per game meat.
In fresh meat (muscle tissue after slaughter), oxygen can be continuously bound and dissociation with the heme complex of the myoglobinase molecule with unchanged natural properties. There is a relative set of three forms of muscle pigment with unchanged natural properties, which determines the visible color of fresh meat. They include purple deoxymeglobin (restored myoglobin), red oxymioglin (saturated with mycobacterium oxide) and brown methymogolic (oxidized myoglobin). The form of deoxymioglobin usually prevails immediately after the slaughter of an animal. Therefore, freshly dispersed meat may have a purple color. This purple color can exist for a long time if the pigment is not exposed to oxygen. When cutting or shredding, the pigment will be subjected to the influence of atmospheric oxygen, while the purple color can quickly turn into a bright red (oximeoglobin) or browncolor (metmioglobin). Thus, although deoximio globin technically points to more fresh meat, the main criterion for assessing the freshness that the consumer uses is red or "natural" colorium. It can be assumed, but not limited to, that the predominant red color of fresh meat is when at least 50% of the molecule of deoxyhemoglobin is saturated with oxygen to the state of oxy myo globin. Changes in relative percentage but not limited to the notion that the predominant red color of fresh meat is when at least 50% of the molecule of deoxyhemoglobin is saturated with oxygen to the state of oxy myo globin. Changes in relative percentage but not limited to the notion that the predominant red color of fresh meat is when at least 50% of the molecule of deoxyhemoglobin is saturated with oxygen to the state of oxy myo globin. Changes in relative percentage
Each of these forms can continue to come out when fresh meat is exposed to oxygen for a longer period of time. Direct transition of purple to the desired bright red color or unwanted brown color may depend on the partial pressure of oxygen on the surface. The purple color may contribute to the low-oxygen level, and it can prevail at oxygen levels, amounting to 0-0.2%. The only brown color can be promoted by only a third of the higher oxygen level (0.2-5.0%). The buyer is beginning to distinguish when the relative amount of methomoglobin is 20%. Clearly brown co-liner will be well visible at 40% of methygrobin, which usually leads to the impossibility of selling the meat, although it remains nutritious and useful for use.
Some biochemical reactions occurring in the muscle tissue after slaughter may also be influenced by the color of fresh meat, for example, due to the presence of glycolytic enzymes that convert carbon dioxide into carbon dioxide. Renewable coenzyme, called reducing metmiohlobinu, schoznahodyatsya in the flesh, in turn metmiohlobinnazad deoksymiohlobin and their activity is called "MRA" which is an abbreviation of "activity zvidnovlennya metmiohlobinu." MPA can be described as the ability of muscle tissue to restore methylohexin to reverse its transition to the deoxymoglobin state. MPA will be suspended when the oxidized substrates will be depleted, or when the heat or acid change the natural properties of enzymes. When enzymes stop their activity or change the natural properties, the iron of the hemic pigment will automatically be oxidized to the form of methemoglobin, with the co-radical color will be stable and overwhelming. It lasts for a period of time after slaughter, which depends on the degree of exposure of oxygen to the muscle tissue of the meat. During this period, continuous consumption of oxygen by muscle meat will be carried out. The rate of oxygen consumption is called "SRF". When meat with a high SRF is exposed to oxygen, a stressed state of oxygen will be reduced so quickly that metmioglon-bin in a favorable way appears below the species-my surface. If it is near the visible surface, it will affect the perceived color of the meat. MRA is important in order to bring methemoglobin to the minimum of this layer, which is formed between the colored surface and the purple intrinsic part. When exhausting MPA occurs, the brown metallic layer of methygrobin becomes high and migrates to the surface, leading to the end of the demonstration line. When the MPA is juice, the methyoglobin layer will be thin and sometimes non-dimmed with the naked eye.
Characteristics such as MPAs and RAPs relate to the types of packages that are best suited for retail and retailers so that for longer periods of time they can continue the desired appearance of the meat. Packages, which are hermetically sealed with oxygen barriers, lead to low levels of oxygen on the surface of the meat. So when the education takes place
29

Methemoglobin, the apparent surface changes with an undesired brown color. However, if the OCD is high enough to keep it higher than that of oxygen that migrates through a painkiller film, and MRA is sufficient to restore the metiumglobin formed on the surface, then natural decoxymоglobin replaces mettioglobin. After a certain period of time, the perceived color will be changed from brown to purple. These colors are unacceptable to the buyer. For this reason, vacuum packaging in itself is historically an unacceptable form for ready-made fresh meat in the shell, although it is used to transport sub sorts of cuttings and other large pieces of meat from slaughter to shredders that carry out retail disassembly, with the goal of further processing and re-packaging. On the other hand, vacuum packaging is a form of packaging which is chosen for heat-treated and cons-combing meat products, in which the natural properties of pigmentumglobin have been altered by heating. Heat treatment causes a change in the natural state of the globin part of the molecule of nitrotized myoglobin and the separation of the hemovirus. A characteristic co-lire for canned and processed meat is a dissociation nitrogenated heme complex. When oxygen is eliminated from the packaging with the processing of canned meat, the color and taste of the product may become slightly worse than in the event when oxygen is present. In the present invention and the invention, the oxygen must be removed from the medium that feeds fresh raw meat, before a predominant color can be detected. After slaughter and dressing, some of the oxygen penetrates into the meat. This oxygen is eliminated by using ODP / MRA activity. This activity also contributes to the advantage of the myoglobin molecule in the form of deoxymioglobin. It can be assumed, but not limited to, that the activity of the OCD / MRA, in addition, reduces the recovery of nitrite to nitric oxide, when sodium nitrite uses an agent that improves the color of the myoglobin. In this case, the formation of deoxyhemoglobin and nitric oxide ensures the possibility of manifestation of nitroxymioglobin. Oxygen itself is an agent that improves color, because it causes the formation of oximeoglobin, which was described here before. However, oxygen interferes with the reaction wells, which form deoxymioglopin and nitric oxide. Therefore, it creates an obstacle to the manifestation of the resulting color in the presence of nitrite. Thus, the preferred aspect of the present invention is that the oxygen barrier layer is selected,
AGENTS WHICH FOLLOW THE MYOGLOBIN COLOR
In the first embodiment of the invention, the modified agents enhance the color of the myoglobin. "The agent that improves the color of the myoglobin" refers to any agent (or its precursor) that may be bound to or interact with any structure that contains myoglobin with unchanged
natural properties (including deoxime-oglobin, oximeoglobin, metmioglobin, carboxymio globin and oxide-nitrogen myoglobin, but not limited to), available in fresh meat products, for obtaining or preserving the desired color, for example, in red, indicating Sweetness of meat. The agent that improves the color of the myoglobin may also interact with the hemoglobin present in the meat product or interact with it to obtain, maintain or enhance, that is, "fixing" the desired color. Thus, the agent that improves the color of the myoglobin is not a color additive , and acts as a color fixer.
In one preferred embodiment of the invention, a myoglobin-enhancing agent is a "nitric oxide donor compound" ("NOOR donor") that provides an oxidiazole (NO) molecule that is bound to the myoglobin present in meat products to preserve or intensify the redness or giving of this color, or other beneficial coloring
meat products. The compound serving as a donor of nitrogen oxide releases nitric oxide or is a precursor, for example, a nitrate acting as an intermediate compound, which results in the formation of oxide azoto that will be bound to the myoglobin molecule in meat products. Examples of components that serve as a nitrogen oxide donor include nitrosodium sulfonates, including, for example, Egget salt (I / U (ZO2) Ma) 2 or (I / U (ZOZK) 2), inorganic nitrates (MNO3), where corresponding oppositely charged ions (H +) include alkali metals (eg sodium, potassium), alkaline earth metals (eg Calle this), transition metals, protonated primary, WTO-rynni or tertiary amines, or quaternary amines, or ammonium, and include, for example, selitre, as well as inorganic nitrites (MICO2), where the oppositely charged ions (M +) include or metals (eg sodium, potassium)

Compounds serving as a nitrogen oxide donor can deliver a single molecule or a large number of nitric oxide molecules. According to some aspects, compounds that serve as a donor of azo-tin may be a polymeric material that contains several nitrogen oxide transfer sites and, therefore, can produce a large number of nitrogen oxide molecules. Preferably, nitric oxide has been isolated from the polymer chain. For example, US Pat.

Agents that improve the color of the myoglobin also include any compound that acts as a ligand for myoglobin and results in the formation of the desired colour, or any compound that acts as a base and leads to the formation of such a ligand. For example, an agent that improves the color of the myoglobin can be a compound that serves as a donor of carbon monoxide. Carbon monoxide is known to form a complex compound with a hemoglobin for the formation of the desired external appearance of the muscle. The compound, and which serves as a donor of oxide of carbon monoxide, is any compound that releases carbon oxide or acts as a base, leading to the formation of carbon monoxide. Alternatively, the color enhancing agent may be a compound serving as a sulfur oxide donor (50), a nitrogen monoxide (N2O) donor compound, a ammonia (NH3) donor or a compound which serves as a donor of hydrogen sulfide. Such compounds give a specific ligand or act as a base which results in the formation of a specific ligand. The species include complexes of ligand-dau / heme / transition metal and protoprofirin-iron and ligand complexes, including, for example, carbon / heme complexes / transition metal, and complexes of protoporphyrin iron and oxidecarbon. Compounds serving as a donor of oxide-carbon, compounds serving as an oxidizer donor, compounds serving as a nitrogen oxide donor, and compounds serving as a hydrogen sulfide donor include polymer materials with a corresponding functional group serving as a donor chemically bonded to a polymer chain. The compounds include complexes of ligand-dopamine / transition metal and protoprofirin-iron and ligand complexes, including, for example, carbon / heme / transition metal complexes, and protoporphyrin complexes of iron and carbon monoxide. Compounds serving as a donor of oxide-carbon, compounds serving as an oxidizer donor, compounds serving as a nitrogen oxide donor, and compounds serving as a hydrogen sulfide donor include polymer materials with a corresponding functional group serving as a donor chemically bonded to a polymer chain. The compounds include complexes of ligand-dopamine / transition metal and protoprofirin-iron and ligand complexes, including, for example, carbon / heme / transition metal complexes, and protoporphyrin complexes of iron and carbon monoxide. Compounds serving as a donor of oxide-carbon, compounds serving as an oxidizer donor, compounds serving as a nitrogen oxide donor, and compounds serving as a hydrogen sulfide donor include polymer materials with a corresponding functional group serving as a donor chemically bonded to a polymer chain.
The agent improving the color of the myoglobin is preferably present in the desired concentration in contact with the product. The packaging layer for the food contact product preferably contains an agent that improves color, the concentration of which is high enough to provide or preserve the desired appearance of the meat product. Preferably, the color improvement agent is present in a shar that is in contact with the food product at a concentration sufficient to convert at least 50% of the myoglobin molecules to the contacting surface of the meat into the desired state of ligand bonding. The concentration of the color improvement agent is preferably selected so as to bind the ligands that provide the desired appearance or color of the meat, with the myoglobin molecules, at most% or less of the product. For example, it is desirable that the agent that improves the color of the myoglobin which served as a donor of nitric oxide, was in a concentration that was sufficient to convert at least 50% of the myoglobin molecules on the surface that is in contact with meat into the oxide-nitrogen myoglobin, and the color improvement agent is niacin, the concentrate Nationine of niacin is chosen more than the concentration of natinum, naturally found in meat. Answer
bottom to Eeapagbeop and others. (1980, Composition of Food Products.Meat for sausages and snacks (raw, peanut, cooked) Guide No. 8-7, US Department of Agriculture, Department of Education and Education, Washington, DC, Columbia), niacin is naturally present in home-made poultry and red meat in the amount of about 0.05-0.09 mg / g. In the present invention, if as a color improvement agent, niacin is used and it is introduced into meat products, it is customarily used in amounts in excess of 0.1 mg / gm.
The agent that improves the color of the myoglobin can be applied to the inner layer of the polymer film by spraying or rubbing, or by the use of another agent, or this agent can be introduced into the inner layer.
According to other aspects, the agent that improves the color of the myoglobin is introduced into the freshly prepared product containing myoglobin, or applied to the surface of a fresh meat product containing myoglobin. An agent that improves the color of myoglobin may be applied to a fresh meat product containing myoglobin, prior to packaging by dipping, rubbing, dipping, or using another method. An agent that improves the color of myoglobin may be administered a meal containing myoglobin, by mixing this agent directly with meat, for example, minced meat. As a variant, an aqueous composition of an improving agent can be prepared and mixed with water. The aqueous composition may be a suspension of an agent that improves the color of the myoglobin, with water, or the solution of this agent in water.
For the color enhancer, other additives known to those skilled in the art can be added to the data. These additives can be added directly to the food product, or to the padding film, both by the introduction of the inside, and by spraying the surface or its rubbing. Examples of other preservatives include monosodium glutamate, salt, flour paste, soy flour, pro-tein soy concentrate, lactose, dry residue of corn syrup, antifungal agents (which suppress growth of dandruff and mildew), antibiotics, sugar, glycerol, molluscic acid, ascorbic acid, erythorbic acid, α-tocopherol, phosphates, rasma-rin extract and sodium benzoate.
Agents that improve the color of the myoglobin, or their solutions or dispersions, may be colorless, for example, as sodium nitrate, or, for example, sodium nitrite, may have their own dim color (that is, they may not be completely free of Inni), but this color by itself is not usually enough bright to act as a significant colorant or coloring admixture. However, this does not preclude the use of colored agents that enhance the color of the myoglobin, which have a peculiarcolor, or a combination of the color-giving agent, with one or more natural and / or artificial colors, pigments, coloring reagents and / or aromatizing agents , such as annatto, bixin, norbixin, beet

It can be assumed that the agent, which improves the color of myoglobin, will interact with myoglobin in meat products, while maintaining, maintaining or enhancing the desired color of meat. Myoglobin does not include the protein part, which is called hemo, and the protein part, which is called globin. The gem part involves an iron atom in a flat ring. A globulin-like fragment can create a three-dimensional structure that surrounds the heme group and stabilizes the molecule. Gemov's group creates an open mes-this connection, which can bind certain ligands that have the proper form and location of the electron atom of iron. When the ligand is absorbed and its connection with the hemoma, the positioning of the electrons of the ligand can change the shape of the Globe-new part of the molecule in such a way that it ensures weak absorption characteristics of the gem group. So,
When there is no ligand in hemi, myoglobin is called deoxymoglobin, which has a purple color (which is sometimes characterized as purple, saturated red, dark red, reddish blue or reddish-red). Molecular oxygen, O2 ("oxygen"), acts easily as a ligand that will be linked to the germ group, providing the biological transfer of oxygen from the blood stream to the mitochondria in the intracellular cell. When there is a connection of oxygen with hemogram, purple deoxymioglin becomesoxymioglin, which is distinguished by red colon. When separating the oxygen ligand from oxy-myoglobin, the oxidation of the iron atom occurs while leaving iron in the state of trivalent iron. Oxidation of the atom of iron leads to the inability of the molecule to the normal connection, which is the oxygen. When the chemical status of the iron maybe changed from the glandular (Re<sup>2+</sup>) on iron (P.<sup>3</sup>+), the three-dimensional structure of the globin part can be modified in such a way that ensures the possibility of coupling water molecules with hemum. The connection of the molecule of water with trivalent iron, which occurs in hemi, leads to a weak adsorption of hemu. The oxidized form of myoglobin and the water molecule in the hydrogene group is called methymogon, which has a brown color. It is possible to assume that, before the brown coloration results in the oxidation of the iron atom. Other heme ligands, which differ from oxygen and water, can also affect the color of the meat. For example, the presence of carbon monoxide (CO) can ensure the presence of fresh meat reddish-colored, similar to that obtained in the case of oxygen. Although it should be assumed that nitric oxide (ICO) can cause the appearance of dull red color or persistent pink color in the case of canned meat,
nom in fresh, raw, not subjected to technologicalprocessing or non-canned meat. It is found that the manifestation of such a desirable bright red color may take many hours, it usually takes from 1 to 5 days, and that the first co-liter of meat in a vacuum package that has oxygen barrier properties can be changed. on unwanted brown color, until there is an unexpected transition to the desired red color.
Other variables that affect the stability of the globin part also affect the affinity of the gem group related to oxygen, and the tendency to oxidize the chemical state of the iron atom. The acidity and high temperature, such as that associated with cooking, can change the natural properties of the globin part, resulting in the instability of the heme group. In the absence of stabilizing liming ligands, the oxidation of iron heme occurs automatically, when the globin changes naturalproperties.
POLYMER PACKING FILLES FOR CHARACTERISTICS
The present invention provides oxygen barriers for the packaging of food products, which may include surfaces for contact with the food containing an agent that improves the color of the myoglobin. The phrase "contact surface with food" refers to the part of the packaging material, which is intended for contact with the surface of the packaged product. Preferably, an article intended to pack a food product includes a contact surface with a food containing an improving agent of myoglobin in an amount effective to promote production or to maintain the desired color after contact with the product. The agent, which improves the color of myoglobina (MVA), will preferably contact the surface of the meat in an amount sufficient to obtain the desired red color, which mainly does not penetrate the undesirable depth of the thickness of the food product in a reduced amount of oxygen (the development of this color can take, for example, 1 to 5 days). Preferably, the MVA could be found on the surface of the film in contact with the food product (or on the surface of the food containing the myoglobin) in an amount from about 0.01 to about 3, to about 5, to 10 micromoles / inch<sup>2</sup> and with increments about 0.1 micromolar. Must be used larger or smaller mVa, with the brightness of the color being varied depending on the presence or absence of myoglobin.
Thus, the surface of the packaging product in contact with the foodstuff and the product preferably contains an enhancing agent of myoglobin in a concentration that is high enough to create and / or preserve the desired coloration of the surface of the fresh meat product, but rather low to prevent undesired spreading color in the mass of the product. Preferably, an agent that improves the color of the myoglobin is present on the surface that is in contact with the food product at a concentration sufficient to contact at least 50% of the myoglobin molecules when in contact with the surface of the meat, to the desired binding state of the ligand-

dou An acceptable amount or concentration of a myoglobin-enhancing agent is preferably selected so as to bind the ligands that provide the desired coloring of the meat to the myoglubin molecules by at most% inches or by 1/6, 1/8, 1 / 10, 1/12, 1/16, 1/20 inches or less
Meat products, although deeper penetration can be guaranteed if desired. For example, it is desirable that the agent that improves the color of the myoglobin that serves as a nitrogen oxide donor is present at a concentration that is sufficient to convert at least 50% of the myoglobin molecules to the contact surface with the meat into the oxide-nitrogen myoglobin. The agent improves the color of the myoglobin, it can be deposited on a single-layer film or on the inner layer of a multilayer film, or it may have been inserted into it.
The agent that improves the color of the myoglobin is distributed on the surface that is in contact with the foodstuff, preferably uniformly or unevenly. The minimum amount required to ensure the desired coloration depends on the concentration of the myoglobin present in foodproducts. For example, beef products with a content of myoglobin of 10 mg / g may require an amount of 10 times that of a poultry product containing 1 mg / g of mytagglin. In addition, if the desired penetration depth is 0.25 inches, then at least 2.4 mmoles (micromolar) of the agent is required for exposure to all myoglobin molecules (molecular weight of myoglobin is about 17000 g / mol) per square inch beef at a depth of 0.25 inches. , which improves the color of myo-globin,<sup>3</sup>)) Nitrite sodium, as a preferred agent, improves myelosuric acid, has a molecular weight of about 69 g / mol. Thus, 2.4 micromoles of the number N02 are weighed byOD 66 mg and the total number of myoglobin in 4.1 grams, containing 10 mg of myoglobin per gram, gives 41 mg. Beef usually contains a myoglobin level of about 3-10 mg / g. The vast amount of agent that improves the color of myoglobin, which should be present on the product, is 0.72-2.4 mc-rmol / inch<sup>2</sup>. Similarly, pork containsmioglobin at a level of about 1-3 mg / g. Packing product in this case should provide 0,24-0,72 micromoles / inch<sup>2</sup>. In the case of a homeoptium containing myoglobin in an amount less than 1 mg / g, it is preferable to use a packaging product that provides less than 0.24 micromole / inch<sup>2</sup>, for example, 0.12 micromoles / inch<sup>2</sup>. You-rib, in which, as an agent that improves the color of the myoglobin, sodium nitrite is used (molecular mass is 69 g / mol), preferably it should provide 0,050-0,166 mg / inch<sup>2</sup> for meat products from beef, 0.017-0.050 mg / inch<sup>2</sup> for meat products made from pork and less than 0.017 mg / inch<sup>2</sup> for poultry meat products. The product, which is 0.17 mg / inch<sup>2</sup>, will be suitable forvarious types of fresh meat.
The increased amount of the agent that improves the coloriglobin may be preferable to muscle tissue with a darker color, which may have higher levels of myoglobin. If the agent that improves the color of the myoglobin, a predominant matrix containing; for contact with a food product, a layer of single-layer or multilayer packaging film, only a part of it is able to effectively migrate from the surface of the film to the surface of the product for interaction with myoglobin. It is possible to expect the appearance of films with levels of the agent in those exceeding 20 times or more that the number required for effective fixing the color.
Thus, the amount of the agent that improves the color of the myoglubin per unit area of the surface that is in contact with the food product, may be chosen in such a way to provide the desired coloring surface of the packaged fresh meat. For example, a layer for contacting a food product may range from about 0.005 to about 0.900 mg / in.<sup>2</sup> an agent that improves the color of the myoglobin, for example sodium nitrite, preferably from about 0.010 to about 0.400 mg /<sup>2</sup>, and most preferably from about 0.100 to 0.300 mg / inch<sup>2</sup>. In the case of beef products, the layer for contacting the food product may include, for example, about 0.200 to 0.250 mg / inch<sup>2</sup> an agent that improves the color of the myoglobin, in the form of sodium nitrite, while less than the concentration, for example, about 0.100-0.150 mg / inch<sup>2</sup> can be used for pork products.
It is desirable to have a uniform dispersion or coating having a particle size of about 35 microns (microns) or less but preferably 10 microns. Although alsomay be used larger particles of particles, the film to its use in this case, will have less attractiveness of the aesthetic point of the zone. If the size of the particles is significant, it can lead to the initial spotted appearance, although there is a tendency for alignment, and after the end of the time, the homogeneity becomes even greater, and the desired uniform color (ie, lack of spot or surface defects) often occurs in the transition from brown to red to red . Preferably, the agent, which improves the color of the myoglobin, could be applied by the method of wetting the surface of the film layer, which is to contact the food, using for this purpose the agents forming the film, surfactants, binders and other compounds. For example, in accordance with the appended invention, the agent that improves the color of the myoglobin can be sprayed onto the surface of the film that should contact the food product. Tubular films and membranes may also be coated but using other means (including well-known methods of immersion and sediment-tion). Typical agents that improve the color of the myoglobin, it is not easy to pass through the film wall and, therefore, it is preferable to precipitate such an agent from the inner side of the sleeve and / or apply the agent to the inner surface of the sleeve (for example, during the laying of the folds) by spraying, because the external application (for example, immersion) needed can be sprayed on the surface of the film, which should contact with food produktom.Trubchasti films and membranes can also butypokryti but using other means (vklyu nominating well-known methods of dipping and deposited Lock).

A complex and more expensive sweep operation on the outside of the inner side of the sleeve to ensure the contact between the agent that improves the coloriglobin and the surface that is to contact the meat. The application of other impurities and coating compositions by spraying the solution during or after the laying of the folds is a common and economical way, and contributes to ensuring a properly calculated distribution of the covering of the inner surface of the sleeve. For example, ointments and other compositions are applied by different methods, such as deposition, spraying, or contact coating of the inner surface of the tubular-polymeric membrane by means of a fixation for laying the folds, and these are well known (see, for example, for example, U.S. Patent No. 3,778,379 (named after ZPiPeig), 3451827 (on behalf of the VerbindTogb), 4397891 (on behalf of KaeIihegh, etc.) 5256458 (on behalf of Oheieu, etc.), 5573800 (on behalf of SHІІpoІІ) and 6143344 (on behalf of Йоη, etc.), all of which are entered here with reference to them). The forging of the invention may be coated with an agent having the features of the invention that improves the color of myo-globin by deposition in order to obtain a uniformly thick coating.
The application of tubular or non-tubular forms (for example, to a sheet or web) of film for the packaging of a food product can be effected by dry or wet spraying, or by spraying, or by coating a roller or coating using a plate of Mayer or rocket nozzle, or with the help of print media (for example, using deep printing or flex-printing) or by electrostatic transfer. In addition, in the process of manufacturingproduction can occur in different places, for example, by mixing, introducing into the mother liquor or adding to the poly-dimensional layer before extrusion, or by spraying, spraying or coating during or after extrusion, or during the formation of po or the sleeve, or during the winding or the manufacture of the bag, for example,
In one embodiment, it is intended that the layer for contact with the food product may contain from about 1000 RPT (0.1%) to 50,000 RPT (5.0%) of the agent, which improves the color of the myoglobin, more preferably about 5000 to 25,000 rpm, and most preferably - from about 7,500 to 20,000 rpm. Of course, the layer for contact with the food product contains from about 1.5 to 2.0 wt. % or less (15000-20000 rpm) of nitrite salt for packaging a fresh product in the form of a beef farther, or from about 0.75 to about 1.5 wt. % and nitrite salts for the packaging of fresh meat products from the pine forest. For different types of meat, it is preferable to use quantities in the range from 0,75 to 2,25 wt. %

Preferably, the films correspond to a large number of functional faces that can be pushed to one or more layers, or to a combination of layers. For example, a one-layer film can combine the oxygen barrier function and the agent contact, which improves the color of the myoglubin, along with one or more additional functions such as puncture resistance, resistance to misuse, printability, moisture barrier creation , the possibility of heat sealing, transparency, high gloss, low toxicity, resistance to low temperature, flexibility at low temperature, etc. As an option, to add functionality opportunities can be used a large number of layers. The present invention is intended for use in a large variety of available on sale of packaging films, such as those sold by Sigadob, Ips. with trademarks AVR, Sieag-TIIe, Sok-TIIe, RegPheh, Rho-Siahs, Rgo-TIIe, Sigiat®, Sigio® and Ziggoipb, and others, such as those that place on the marketAISap, AzPI, SguOuAs, KigaPa, Wesiog, RhIIUU , RgIpIrask, UIzhkaze and SHIRak with trademarks orfacilities of the trademark Sguuoas®, T-SegIez, Sguuas® E-ZeaI MaIgiIaZ, AISap O® SegeIz, AISapReyeI RieI ™ ReeI ZuZiTets, AISap O<sup>4</sup> Eigth Epidemic, KegPaIop®, AISap Maga EIech® Mop-EOGITIPI EITI, SHIrak SotIiPeGt, ShIrak ViAiOp, ShIrak ViAhEg and Shira VIAkOR. Typically, in such a way as to obtain useful results, a food packaging film, made according to the present invention, may have an inner layer for contact with the surface of the food product, which also serves as a sealing layer, as well as an outer surface layer , which has a heat resistance and resistance to improper handling, with an average layer between them, that place oxygen barrier material. Another usual adhesive film has adhesive layers on each side of the middle oxygen barrier layer for joining with the surface layers.

Options for the implementation of multilayer films for the packaging of foodstuffs for the invention may have an outer surface and an internal top, and include 2, 3, 4, 5, 6, 7, 8, 9 or more polymer layers.
Film thickness
The product for packaging the foodstuff can be made in the form of a single-layer or multilayer film, the total thickness of which is less than about 10 milli (thousandths of an inch), but more preferably that the film has a full thickness of from about 0.5 to 10 milli (12.7 -254 micron (μm)). The thickness of the film in many embodiments of the invention is preferably from about 1 to 5 milliL, and in some typical embodiments, from about 1.5 to 3 mill. For example, all single-layer or multilayer films; or any one layer of a multilayer film may have any acceptable thickness, including 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 milli, or an increment between them, which is close to 0, 1 or 0.01 mill. You can also create more thick or thinner films. Although it may be possible to make acceptable packaging films for food products,<sup>!</sup> the thickness of the most typical films will be within the range of 1.5-3 mils (38-76 microns). Particularlypreferable for use as films for food products are films in this embodiment, whenlarge layer film has a thickness of about 2 to 3 milli (50.8-76.2 micron). Such films provide satisfactory resistance to improper handling and the possibility of their processing.
The product for packaging a food product can be made in the form of a single-layer or multilayer sheet having a total thickness of less than 10 milliliters, more preferably a sheet having a total thickness of from about 10 to 50 milliL, and most preferably a sheet having a full thickness of about 10 to 30 milliL .
Layers for contact with food and forsilting under the action of heat
It is important that the film for the packaging of the haphth products, according to the invention, is malasar, intended to come into contact with the food product. This layer can also function as a layer that creates a heat seal or enhances the ability to seal under the action of heat, although the tubular plastic shells can be used and sealed, for example, by using clips known in the art. In the preferred films according to the present invention, a layer for contacting a food product having sealing properties is used.
The term "heat-sealing layer" or "sealing layer" can be used interchangeably to indicate a layer that provides heat-sealing sealing, that is, capable of connecting with melting using conventional heat-generating means of indirect action that generates sufficient heat at least on one contact surface of the film to transfer it to the limiting contact surface of the film and form a connection between them without losing the integrity of the film. The connection between
the boundary inner layers are preferably sufficient physical strength to withstand the patching process, as well as subsequent handling with it, including, for example, stresses created by accompanying such processes by stretching and pulling out the presence of a mass of product that is sealed inside the packaging with the use of a film that is a layer that is compacted by heat. It is important that the connecting area of the contact is still heat-resistant, to prevent leakage through a gas or a liquid when exposed to temperatures above or below the ambient temperature, for example, during one or more of the following cases : packing operations, and storage, loading-
unloading, transporting, displaying or disposing of a food product. Heat-sealing compartments can be designed in such a way that they correspond to different conditions for the expected use, while in the art, various types of heat-induced heat shrinkage are known and may be used in conjunction with the present invention. In the case of some variants, the seal produced by the action of heat can be exposed to the temperature of the conditions under which there is a pasteurization or thermal treatment, for example, in a sealed bag, in a package in the form of a vacuum membrane or a package in the form of a sealed tray. When used in cases of heat treatment inside the packing-forging, such seals must withstand the temperature rises raised to about 160-180 T (71-82 ° C) or higher, for example, up to 212 T (100 ° C), pro- the traction of a long period of time, for example up to 4-12hours in the surrounding environments, which may vary from the state of the warmed air or steam to the state of immersion in hot water. Preferably, the layer that serves to contact the food product or to seal under the influence of heat not only provides the possibility of compaction in relation to itself, but could also be sealed with respect to other objects, films or layers, for example, to a tray, when it is used as a film that acts as a lid, or to the outer layer in the event of sealing onward, or in the specified variants for the outer wrapper of the tray. In addition, in some embodiments, there is no need toperform the heat seal against the sha-r, which purpose tion to contact harchovymproduktom and contains an agent that improves color mioh-lobinu. which can vary from the state of heated humid air or steam to the state of immersion in hot water. Preferably, the layer that serves to contact the food product or to seal under the influence of heat not only provides the possibility of compaction in relation to itself, but could also be sealed with respect to other objects, films or layers, for example, to a tray, when it is used as a film that acts as a lid, or to the outer layer in the event of sealing onward, or in the specified variants for the outer wrapper of the tray.

The sealing layer is preferably located at the inner surface of the packaging film or is packed from; this surface, while it can be an internal surface layer, which provides the possibility of forming a single-layered or multilayer film for obtaining packages, for example, when used as a pressure container condensed relative to the tray, for example, when used as a film that serves as a lid , or compacted in relation to a film that serves as a lid, for example, when it is used as a tray. The sealing layer can be an agent that improves the color of the myoglobin and a pre-dense polymer that is compacted by heat,

for example, a copolymer of ethylene and α-olefin, a mixture of nylon or an ionomer. The upper layer can also be a layer that is compacted under the effect of the heat, and can be used for this purpose in place of the inner layer or in addition to it.
The layer for contact with the food may be a sealing layer, and may also contain a polymeric material that is compacted under the action of the heat, for example, polyolefin or a mixture thereof, for example, polyethylenes such as low density polyethylene (IBBE), high density polyethylene (NBRE ), copolymers of ethylene and α-olefin, including, for example, plastomeres, low density polyethylene (UBBRE) and linear polyethylene-bearing density (BBBRE) or polypropylene homopolymers, polypropylene copolymers or homogenous polyolefin polymers for example, those made in catalysts with a limited geometry or in metallocene single catalysts, including, for example, copolymer-ethylene or propylene with at least one of C4-8 or higher α-olefins (e.g. butene-1, hexane-1 or octen-1, or their combinations), the greater part of the polymeric elements that are scoured from ethylene or propylene. Copolymers of ethylene and vinyl acetate (EUA), ethylene toluene acetate copolymers (EVA), ethylene copolymers and methyl ethyl acetate (EMA), ethylene copolymers and methacrylic acid (EMAA) copolymers or ethylene urea ethyl acrylate copolymers (EAAs) are also acceptable mate- rials for the formation of internal surface-layer, which is compacted under the action of heat. The ball that serves for sealing and / or contacting the food product may also contain an ionomer which is, in fact, neutralized with ethylene and acrylic or methacrylic acid methyl ester. Suitable materials of a layer that is used to compaction / contact with a food product often include ionomers, polyolefins or their mixtures, for example, those disclosed in US Patents 6964816, 6861127, 6815023, 6773820,
6682825, 6316067, 5759648, 5663002, as well as the published applications for the United States Patent No. 2005/0129969 (on behalf of ZnElI et al.) And 2004/0166262 (on behalf of VyssNe et al.) Which are incorporated herein by reference to them.

Barrier Layers
Barrier layers can be manufactured, which can be used as an agent that improves the color of myoglobin. The barrier layer preferably operates as a gas barrier layer, although other types of barriers, such as the luminescence bubble layers, may also include an agent that improves the color of the myoglobin. The gas barrier layer is over-the-air represents the oxygen barrier layer, and it is usually an intermediate layer, located between the first and second layers. For example, the oxygen barrier layer may be in contact with the first surface layer and the adhesive layer, or may be located between two binding layers and / or between two surface layers.
In order to achieve all the benefits provided by these inlets, it is important that the film with the agent, which improves the color of the myoglobin, has been used in vapors in combination with an atmosphere in which the reduced oxygen content is reduced. The barrier layer may create the necessary oxygen barrier to desirable store the item that should be packaged in the expected storage conditions. Accordingly, in one aspect, the oxygen barrier is used in the case of packaging for meat or packaging materials stored in an atmosphere with reduced oxygen content. The oxygen barrier is preferably selected in such a way as to provide a sufficiently reduced oxygen permeation for the ability to absorb or preserve the desired color within the packaged meat. For example, a film may contain an oxygen barrier having permeability, for oxygen, which is rather low for the reduction of activity related to the restoration of myoglobin, tesenzyme in meat that restores mettioglobin, and / or to preserve the atmosphere with a reduced content of the contact in the body; with meat, with a measure of reducing the oxygen that binds to the myoglobin on the surface of packaged fresh meat.
The oxygen barrier layer may comprise any suitable material, for example, nylon, Euon, RUN, polyvinylidene chloride, polyamide, a complex polyester, polyalkylene carbonate, polyacrylonitrile, nanocomposite, metallized film, for example, by depositing aluminum vapors on polyolefin and the like, known to skilled specialists. in this industry. The layer of the film that creates the oxygen barrier may preferably contain EEOON, although also important oxygen barrier layers containing copolymer polyvinylidene chloride - vinyl chloride (RUBS or UBS-CS), or copolymer of vinyl chloride and methyl acrylate (UBS-MA), and may also be preferred mixtures thereof. The barrier layer can also provide the desired optical parameters when it is vinorarged by stretching, including prose and low turbidity, as well as tensile behavior compatible with the layers surrounding it. It is desirable,
45
96258
46
size of shrinkage, mainly at lowtemperatures, orientation of lightness, resistance to overspray and optical properties. Acceptable Com-Shinei and this layer in multi-layer glass films produce less than 15%, for example, and from 3 to 13% of the total thickness of the film, and preferably less than about 10% of the total thickness of the multilayer film. More thicknesses can be used, but there is a tendency to a relative travel of polymers that create an oxygen barrier, and therefore it is possible to assume that in other layers less expensive polymers will be used to provide the desired properties when the applied thickness is used, to provide a property such as the creation of a gas barrier, for the combination of film layers. For example, the thickness of the average oxygen barrier layer can preferably be less than about 0.45 milliliters (10.16 microns) and more than about 0, 05 milli (1.27 micron), including a thickness close to 0.10, 0.20, 0.25, 0.30, 0.40 or 0.45 mill. It is preferred that multilayer films include an average oxygen barrier layer. Can be used any acceptable materials to form a layer that creates an oxygen barrier. Such a charcoal can preferably contain EHO, although it may also be preferred by oxygen barriers containing polyvinylidene chloride-vinyl chloride copolymer (RUCUS or UUC-CS) or copolymerivinylidene chloride methyl acrylate (UUC-MA) and mixtures thereof. One of the predominant barrier materials of Euon is polymer E151B, where the molar ethylene composition is 44%, which sells ΕνθΙστοοοο οί Ategis with the trade name ΕναΙ® I_C-1151B. Other examples of EuOn, which may be acceptable, can be obtained from Νίρροη Sobze (or Zoagiz, I_I_C in the USA) with the trade name ZaagpoI® AT (Euon with 44% ethylene ethanol) or ZoagpoI® ET (EuOn with 38% molar ethylene). Oxybeering films for the packaging of food containing Euone, such as a myoglobin-enhancing agent, can be formed by methods disclosed in U.S. Patents 7,018,719, 68,150,23,
6777046, 6511688, 5759648, 5382470, 4064296, all of which are introduced here in their entirety by reference to them.
Nylons or nylon-new mixtures can be used to provide the oxygen barrier properties of the skin. In addition, a combination of barrier materials can be used. For example, the magnitude of the number of barrier layers of nylon and EOON is sometimes used to provide acceptable barrier properties in the case of packagingproduct and meat, while the layers are mixtures of Euon and nylon. These and other knownmaterials can be used to form a layer that creates an oxygen barrier.
In the case of perishable products, oxygen permeability (O2) is desirable to minimize. For typical films that create an oxygen barrier, the permeability of O2 will be less than about 310 cm<sup>3</sup>/ m<sup>2</sup> for a period of 24 hours, at 1 atmosphere, 0% relative humidity and 23 ° C, preferably less than 75 cm<sup>3</sup>/ m<sup>2</sup>/ day, and even more usually less than 20 cm<sup>3</sup>/ m<sup>2</sup>/day. Barrier poly
Mayors, for example, RUCUS or EWO in the average layer can be adjusted by mixing compatible polymers to change the orientation parameters of the film or its gas permeability, for example, O2. The thickness of the middle layer can be changed, and to obtain positive results, it can range from about 0.05 to 0.30 microns (1.3-7.62 microns).
The outer layer is resistant to improper driving
In the case of single-layer and multi-layer packaging films, according to the embodiments of the invention, since they will be inspected by the user / buyer, the outer surface of the film should enhance its optical properties, in which it may be preferable that it has a strong gloss. In addition, it mustcontact contact with sharp objects andprotect abrasion resistance, and from these pr-tion her upper layer is often called a layer, resistant to improper handling. This stable, improper handling of the upper layer is also possible or not, used as a layer that thickens under the influence of heat. Being the upper surface layer of the film, this layer most often also serves as the top layer of any package, bag, bag, tray or other container, which is made of a film having signs of the invention, and therefore subject to various manipulations and improper handling, for example, from the equipment during packaging, or for washing other packages and transport containers, as well as shelf for storage during transport and storage. Such contact leads to the creation of erosion forces, stresses and pressures, which can cause the stripping of the film, resulting in defects of what is printed, the deterioration of optical characteristics, or even punctures, or in the collision of the integrity of the package. Therefore, the upper surface layer is usually made of materials that are selected in such a way that they are opposed to abrasion and piercing, as well as other stress and misuse, which packaging can be subjected to during its use. The upper surface layer must ensure the easy operation of machineprocessing (that is, to provide the possibility of lightfeeding and manipulating machines, for example, fortransport, packaging, printing oron the part of the process of making a film or bag). It should also facilitate orientation during rooting when the desired film with a significant shrinkage, in particular at low temperatures, is formed, for example, 90 ° C and below. By means of a suitable choice of materials in the upper layers often provide the necessary hardness, flexibility, resistance to cracking at bending, elasticity modulus, tensile strength, coefficient of wear, printing suitability and optical properties. This layer can be chosen so that it has characteristics that are suitable for creating desired seals under the action of heat,
47
96258
48
to be used as a surface for sealing under the heat, for example, when using compression at the outset.
The top layer may be formed from a mixture similar to the mixture for the inner layer. In one embodiment, polyolefin and polymers, and most preferably a composition such as (i) ΕνΑ, (ii) EAO (e.g., νyyPE) and (iii) are used, both for the internal and for the upper layers, a copolymer of ethylene of hexene-1 having a melting point of about 80-98 ° C., and preferably of 80-92 ° C<sup>0</sup>. Each of the three polymorphs is usually 20-40 wt. % of the layer ΕνΑ, when it is used in the outer layer, advantageously contains from 3% to 18% vinyl acetate to ensure optimal shrinkage, if desired, for shrinkage. In the outer layer for obtaining useful results may also be used mixtures EAO.
The thickness of the top layer is usually about 0.5-1.0 mill. Layers of less thickness may prove less effective in terms of resistance to improper handling, while more thicker sheets, although they are more expensive, can be advantageously used to create films that have unique, rather desirable properties, which are in the stability of preprolining and / or resistance to improper handling. Films of a large thickness, usually of 5-7 mils or more, are needed in the necessary cases of use, which can usually be secured with the help of fairly expensive and composite layered film structures, and / or for auxiliary packaging materials, such as protective devices for bone parts , substrate and external shifter.
In one of the barrier layers, according to the invention, the upper thermoplastic layer of the coating multilayer film is found on the opposite side of the middle layer layer of the inner layer and in direct contact with the environment. In the accepted version with three layers, this upper layerdirectly adheres to the middle layer, which is predominantly oxygen barrier layer.
Intermediate layers
The intermediate layer is any interlayer between the upper layer and the inner layer, and may include oxygen barrier layers, binder layers, or layers having functional power, which are useful for the structure of the film or the vectors of its intended use. Intermediate layers can be used to enhance, render or modify a large number of characteristics, for example, the suitability for printing for structures that perceive the printing color, shrinkage, orientation, technology, processing, properties related to the possibility of stretching, draping, flexibility, hardness, modulus of elasticity, the expected splitting, features related to the ease of opening, properties related to the rupture, strength, elongation, optical properties, moisture r'yernyh properties oxygen-
or other gas barrier properties, the selection of radiation, or the creation of a barrier for y-radiation, for example, for the wavelengths of ultraviolet radiation, etc.
Binding Layers
Together with the upper layer, the inner layer and the intermediate layer, such as the barrier layer, the multilayer packaging film may further comprise one or more adhesive layers, also known in the art as "binding layers", which may be selected to facilitate the adherence of adjacent layers to each other in a multilayer film and to prevent unwanted split-tub. Preferably, a multifunctional layer is formed to facilitate the adhesion of one layer to another layer without the need to use separate adhesives through the compatibility of the materials of this layer with the first and second layers. In some embodiments, the adhesive layers contain materia ali, which are found in both the first and second layers. The adhesive layer may, accordingly, be less than 10%, and preferably from 2% to 10% of the total thickness of the multilayer film. Adhesive resins are often more expensive than other polymers, so the thickness of the binding layer is usually preserved at a minimum, which corresponds to the desired positive result. In one of the variants, the multilayer film contains a three-layer structure with an adhesive layer, located between the first and second layer, and in contact with them. In another variant, the multilayer film comprises a multilayer structure consisting of a first adhesive layer, which is arranged between the upper layer and the middle oxygen barrier layer, and in the indirect contact with them, and, moreover, necessarily, has a second binding the layer between the middle medium oxygen barrier layer, and the inner layer, and in direct contact with it to create a five-layer film, and multi-layer films can; contain any acceptable number of contacts ulcerative or adhesive layers with any acceptable composition. Different adhesive layers are made with a predetermined composition and placed in such a way as to provide a desired level of adhesion between the defined layers of the film in accordance with the composition of the layers that are found in contact with the binder layers.
For example, adhesive layers that are in contact with a layer containing a complex polyester, such as PET (polyethylene terephthalate), preferably contain a suitable mixture of polyolefins with other adhesive polymers. One of the predominant components of the adhesive layer, located in the contact with the polyester layer of PET, is the EMAS Zr1330 (which reportedly has a density of 0.948g / cm<sup>3</sup>, a melt index of 2.0 g / 10 min, a melting point of 93 ° C., a softening point of 49 ° C. and a content of me-ethyl acrylate (MA) of about 22%).
The inner, top, intermediate, or binder layers can be formed from any suitable thermoplastic material, for example, from polyamides, polystyrenes, styrene co-polymers, for example, copolymers of styrene and bu-addiene, polyolefins, in particular, elements of polyethylene families such as ΙΙΙΙΡΕ,
49

vinyl, polypropylene, copolymers, polypropylene, ionomers, polybutylenes, alpha olefin polymers, complex polyethers, poly-carbonates, cyclic olefin copolymers, polyurethanes , polyacrylamides, polymers, modified anhydrides, polymers, modified acrylates, lactic acid polymers, or various mixtures of two or more of these materials.
In another embodiment, the upper, inner, and / orone or more intermediate layers may containcomposition with a nylon mixture or actuallycompound from it. Preferably, the composition with the jejunol mixture comprises at least an amorphous nylon, such as a 6I / 6T nylon copolymer, in combination with at least one semi-crystalline nylon homopolymer or copolymer, for example, nylon 6/12, nylon 6/69, nylon 6/66, nylon MXY6, nylon 6, nylon 11 or nylon 12.
In yet another embodiment, one or more of the upper, inner and / orone or more intermediate layers contains at least one polyester polymer. Polysilver polymers contain aromatic polyesters, and more preferably homopolymers or copolymers of polyetylene terephthalate (PET), polyethylene naphthalate and their mixtures. Suitable folding polyester may have an intrinsic viscosity of between 0.6 and 1.2 and preferably 0.60-0.80. The complex polyester may be an aliphatic polyether resin, but preferably an aromatic polyester resin. Materials with complex polyester can be obtained, for example, from dicarboxylic acid components, including terephthalic acid and isophthalic acid as preferred examples, and t-but dimers of unsaturated aliphatic acids.
cyclohexanedimethanol, and 2-alkyl-1,3-propanediol. More precisely, examples of dicarboxylic acids forming the polymeric resins may include terephthalic acid, isophthalic acid, phthalic acid, δ-t-butylisophthalic acid, naphthalenedi-carbon acid, diphenylethery-carboxylic acid, cyclohexanedicarboxylic acid, adipic acid, oxalic acid, malonic acid, butyric acid, azelaic acid, sebacinuric acid, and dimeric acids containing dimeric-unsaturated fatty acids. These acids can be used by themselves or as a combination of two or more species. Diols can be used either by themselves or as a combination of two or more species.
According to some aspects,

which contain aromatic polyester resins that are
a component in the form of an aromatic dicarbon-

Particularly important examples thereof may include copolyester derived from a substitution of a part, and preferably as much as 30% of the molar composition, and more preferably more than 15% of the molar composition, of terephthalic acid to another dicarboxylic acid, for example, to isophthalic acid, copolymers obtained for by replacing the part of the diol component, for example, with ethylene glycol, another diol such as 1,4-cyclohexanedimethanol (for example, 'UhiCiap9921', manufactured by the νοτΗίαη division of Eazithap Setiasia Co.), and a copolymer Dimensions of polyester and polyethylene containing complex polyester as a preferred component (for example, a complex polyester-plated ether between a com-component in the form of a dicarboxylic acid, which substantially contains terephthalic acid and / or its ethereal derivative, and a diol component which mainly contains tetramethylene glycol tetramethylene oxide glycol, and preferably the content of the residual polytetra methylene oxidigly-stalk in the ratio of about 10-15 weight%). It can also be used in a mixture of two or more polyisoboric polyester resins.

Additives to the layers used at the discretion
Polymers used in one or more than one of the top, inner, and intermediate or binding layers of the package for the foodstuff containing them may be introduced with different preserves. For example, the layer may be coated with anti-aging powder. In addition, one or more layers of the film may be added to the tea-like antioxidant, anti-adhesive additives, polymeric plasticizers, acid, volatile substances or gas (eg, oxygen), slip agents, dyes, pigments, organo- The peptic agents, or the film may not contain suchadditional ingredients.

MANUFACTURING METHODS
A single-layer or multi-layer packaging film having the features of the invention may be prepared by conventional processes, which are modified to provide for the administration of an agent that improves the color of the myoglobin. Such methods, which serve to create flexible films, may include, for example, the processes of casting or film production. Single layer or multilayer films can be made using means known in the art, modified in the same way as tytobic, for the administration of an agent that improves the colorigiglobin. Description of acceptable methods of manufacturing and orientation of the films are provided, for example, in US patents 5759648, 6316067 and 6773820, as well as in the United States Patent Application Publication No. 2004/0166262 (on behalf of Wisl et al.), Entitled "Shrink wrapping that is easy to open "
Various methods of fabrication can be used which will be apparent to qualified specialists in the art in light of the proposed idea. For example, US Patent No. 4,448,792 (named Ps.Pigget, etc.) discloses a method comprising the stages of common extrusion, orientation in two axes and irradiation, and US Patent No. 3741253 (named after Vhach et al.) discloses a method of extrusion, irradiation, dispersion / coating using extrusion and orientation on two axes, with both patents incorporated herein in their entirety by means of by force on them. Processes can be changed to exclude orientation on one axis or biped, or to add the next stage of annealing to form a shrink film.
In the case of the predominant manufacturing process, the resin beds and any admixtures are introduced into an extruder (usually one extruder on a layer), where they can be plasticized, providing them melting with the help of heating, and then they are moved to the extrusion head (or joint extrusion) with the formation sleeve or flat sheet. The temperature of the extruder and the head, in general, should depend on the specific resin or mixtures containing the resin to be treated, and acceptable temperature ranges for available on sale of resins are generally good Idoma people in this verticals-with, or indicate the technical summaries, which provide accessto resin manufacturers. Tempera tours during processing can vary depending onother chosen parameters of the process. However, one can expect changes that may depend on such factors as changing the choice of polymer resin,
process parameters. It should be assumed that the actual
process parameters, including pro-
the assignment will be provided by qualified specialists in
this industry without excessive experimentation in
the light of what is disclosed in this document.
In general, it is known in the art that the properties of resins can be further altered by mixing two or more resins with each other, and it can be assumed that various resins, including, for example, homopolymers and copolymers, may form separate layers of a multilayer film or to be admixed with them, or may be added to the data as additional layers, while such polymers include polyolefins, for example; resins in the presence of copolymers of ethylene and unsaturated ester, mainly copolymers of vinyl ester, for example, EuA, or other etherpolymers, low density polyethylene (UBORE), linear low density polyethylene (BBYURE), low density polyethylene (BORE ), high density polyethylene (NORE), ionomers, polypropylenes, or mixtures thereof. Other polymers, which may be included as separate layers or as a combination, include polyamides, for example, neu-lon, ruvus, euon and rnet. These and other resins may be mixed with well-known means using commercially available drum coatings, mixers or blenders.
Additionally, if desired, well-known additives, such as antioxidants, process additives, slip agents, anti-adhesion and anti-valent agents, pigments, etc., as well as mixtures thereof, may be present in the film. For example, a layer comprising an agent that improves the color of the myoglubin and / or other layers may additionally contain an antioxidant, an anti-slip agent, an anti-thiage agent, a colorant, a color enhancer, a flavor agent, gun, organoleptic agent, agent for changing the coefficient of friction, lubricant, surface active reactive wine, encapsulating agent, oxygen absorber, agent for changing pH, film forming agent, lubricant, polyphosphate, humectant, dehydrating agent, antimicrobial agent, chelating agent, binder Well stuff, starch, stabilizer, buffer, phospholipid, butter, fat, pro-tein, polysaccharide, chain transfer agent, or a combination thereof.

has undergone heat treatment, can be formed by reaction of erythrocytes with nitriding agent and reducing agent at elevated temperatures, as described in US Pat. Nos. 5,230,915, 5,44,385 and 5,425,956, which are introduced herein by means of a reference to them.
Various modifiers of polymers may be introduced to increase the impact strength, orientation, elongation and / or other properties of the film. Other modifiers that may be added include those that increase shock tolerance at low temperatures or provide strength, as well as modifiers that modulate the modulus of elasticity or hardness. Examples of modifiers include copolymers of styrene and butadiene, styrene and isoprene, as well as ethylene and propylene.
Used herein the phrase "machine on-line" and its abbreviation "MN" refer to the direction "on the length of the film", that is, the direction of the film when itformed during extrusion and / or coating. Used here the phrase "transverse direction" andthe abbreviation "PN" refers to the direction transverse to the plane perpendicular to the machine or pseudo-directional directions.
Typically, the film is made by a shrink-wrap using orientation when stretching. Orientation in stretching can be ensured by using various known methods, for example, orientation in the machine direction (MN) is important, provided with the use of groups of clamping rollers, rotating from different velocities for stretching or stretching film, sheet or sleeve in the machine direction, while providing an extension in the machine direction, which is established by means of cooking. Other methods include spreading, which is commonly used to orient the sheets, or a well-known technology of a captured bubble or a bubble-shaped bubble for targeting sleeves, for example, as described in US Pat. No. 3,455,444, which is incorporated herein by reference in its entirety. In the case of bubble-receiving technology, the extruded sleeve leaves the head for extrusion of the rye-coffee cooled and flattened, and then mainly will be oriented with re-heating and infusion to form an expanded second bubble, which will again be cooled and flattened. This flattened, stretched film can be wound on a drum in the form of a sleeve, or cut into sheets or cloths and wound, or it can be subjected to further processing, for example, by annealing and irradiation, as described above.
Shrink films usually are such that stretch on two axes. The directional orientation in the transverse direction (PN) is carried out using the aforementioned infusion for radial expansion of the heated film, which is cooled to thicken the film in the expanded form, or by the pre-film extraction in the transverse on-line during the extension. Orientation can be completed in either or both directions. It is important that the output sleeve is simultaneously extended to two axes in the radial
direction (transverse direction) and in the longitudinal direction (machine direction) to create a multilayer film that is shrinkable at temperatures below the melting points of most of the polymeric compounds, for example at 90 ° C or lower. The stretching degree during the orientation must be sufficient to create a film with a total thickness of about 10 mils or less, in which the total thickness of the preferred films will be less than 5 milliliters, and usually 1.0 to 4 milliL. The degree of stretching in the MN usually amounts to 2.5-6, and in the MF - usually 2.5-6. General or full degree of stretching (stretching in MN, multiplied by stretching in PN), which is approximately 6.25-36, is acceptable.
The usual process of annealing, by means of which two shafts are stretched, heat shrink films are heated under controlled tension to reduce or eliminate shrinkage values, which is well known in the art. If desired, the film may be annealed to provide reduced values of shrinkage desired for a specifictemperature. Accordingly, using an annealing process, the shrink films can be fabricated in the form of non-shrink films, for use in some of the embodiments described herein.
Alternatively, films of the invention may be subjected to a variety of treatments by means of radiation. In the process of irradiation, the film is subjected to treatment with strong irradiation, for example, corona discharge, plasma, flame, ultraviolet radiation, X-ray promenes, gamma rays, beta rays, and high energy electrons. Such treatments of irradiation can be made from various sources, including, for example, changing the characteristics of the surface to increase the adhesion of the surface of various substances, for example, to meat or printing ink, or to increase the inclining of the inner layer to improve the inclining of the layer , which is located on the inner side, and to avoid unwanted slamming. The important known use of irradiation of the field is to provide cross-links between molecules of irradiated materials. Irradiation of laminar films to obtain favorable properties, such as crosslinking, is well known in the art and disclosed in US Pat. Nos. 4,737,391 (BizTid et al.) And 40,642,96 (VogPTeil et al.) Introduced herein in all their completeness by means of a link to them.The patent on behalf of Voglseyil et al. The use of ionizing radiation for the formation of cross-linkages of a polymer present in a film is disclosed. In some preferred variants it is preferable to form cross-links in the entire film to expand the range of thermal seal. This is mainly done by irradiating a beam of electrons at equal dosing levels, which are at least about 2 mega (MR), but are mainly in the range of 3 to 8 megarads, although higher doses may be applied. The irradiation maybe performed in relation to the outlet sleeve with the additional balls applied to it, or beacon, or after orientation on two axes. Last

A case called further irradiation is described in US Patent No. 4,737,391 (Business Patent). The advantage of further irradiation lies in the fact that the processing is subjected to a relatively thin film instead of a relatively thick outlet sleeve, while reducing the energy required for this level of processing.
Alternatively, the formation of transverse bonds may be provided by the addition of a chemical agent that serves for this, or by using the irradiation in combination with a modifier for the formation of transverse bonds added to one or more layers, such as on- an example is described in US Pat. No. 5,055,328 (Eugene et al.).
The basis of the present invention is the administration of an agent that improves the color of myoglobin, with an oxygen barrier film. Packing films may have any acceptable structure, but it is important that the agent that improves the color of the myoglobin could be found on the surface of the film that comes in contact with the food product inside the surface or could migrate to it.
If the agent that improves the color of the myoglobin is coated with the inner layer for contact with the food product, or such agent is introduced internally to this layer, then it can be applied by the aid of any suitable method, for example, as described above, and including dry or wet spraying, spraying, mixing, coating, for example, with roller bearings, bearing, settling, insertion into matte mix, printing method, etc. Preferably, an agent that improves the color of the myoglobin is equally distributed over the contact surface of the layer / or across the layer to ensure that any length of the film comprising the layer contains approximately the same amount of compound inside the sealing layer for the purpose of uniform -release to meat through the contact surface.
If the agent that improves the color of the myoglobin, cover the surface of the layer of the film to contact with the food product, then it can usually be carried at different times. Thus, the agent can be applied to the surface of the meat, for example, by immersion or spraying, immediately before or during the preparation of the bag, with the addition or omission of starch, which is used as a contributing agent further opening the bag. It can be caused during the woundoperations, which accompany the cutting operations, or during the manufacture of packages or during the making of sleeves. It can be co-applied with or instead of starch using electron beam irradiation and / or treatment with a corona discharge, as further described in US Pat. No. 5,407,711 (ΜίΙήοίί et al.), which is entered everywhere with reference to it. Multiagents that improve the color of myoglobin, soluble in vinegar or alcohol, while the solutions of such an agent can be applied to the film by themselves, ormay be combined with other agents such as the film forming agents and / or moisturizing agents, or with other materials , such as zein,
casein, dextrin, starch or shellac, etc., for use, for example, to carry the side-son as described in US Pat. No. 6,143,344 (Copper et al.), which is incorporated herein by reference. The agent can also be applied in the presence of an aqueous solution on a film, the surface of which for the contact with the food product is changed in such a way that it is hydrophilic, or adapt or modify otherwise in relation to adsorption or ab-sorption of water-based fluids or oils containing an improving agent color of myoglobin. According to one of the aspects of the present invention, the films that contain the transferring modifier can be used to carry the agent, which improves the color of the myoglobin, using, for example, such films that have in their composition a layer for contact with the foodstuff suitable for effective transfer,
If the agent that improves the color of the myoglobin is injected into the inner layer, it can be added to the base polymer before or during the extrusion film. The base polymer may be any suitable polymer, for example polyolefin, such as polyethylene, and may be a polyethylene with a fairly low density (UBOOR or iOORE), linear low density polyethylene (BBOOR), low density polyethylene (BORE), ESA , polypropylene, ionomer, nylon, RVOS, PET andetc. Mixing the melt is an acceptable method of mixing the base polymer and the agent, which improves the color of the myoglobin. The materials of individual components can be combined into a mixing device of high intensity, such as an extruder. The basic polymer is melting to form a viscous fluid or "melt". An agent that improves the color of myoglobin may be combined with the polymer before, during or after melting. A high-intensity mixing device is used to uniformly distribute a compound that improves the color of the myoglobin, inside the base polymer. The amount and functionality of the dispersing agent may depend on the choice of the agent that improves the color of the myoglobin, from the composition of the base polymer and from the mixing device. It is desirable to achieve optimal pealing for uniform dispersion of the agent, which improves the color of the myoglobin, inside the melt, while the presence of clumps from poorly moistened particles is undesirable. It may be desirable to include in a mixture of additives, for example anti-acid additives, anti-adhesives, or slip agents.

It may be desirable to include in a mixture of additives, for example anti-acid additives, anti-adhesives, or slip agents.
The agent that improves the color of the myoglobin may be added directly to the base polymer directly, or may be provided in a solution, for example, in a solution based on water or oil, which is added to the polymer before the molten polymer state or in such a state. In the case of the direct addition of a dense, granular or powdered agent, it is worthwas to expect that the crushing of a dense agent for the formation of reduced particles will allow

bake it more evenly. It is also to be expected that, in the case of a water-soluble material, the creation of an agent that improves colorimgoglobin in the form of an aqueous solution may provide better dispersion of the compound inside the polymer as compared to the addition of the insoluble agent. The aqueous solution can be prepared from a water-soluble agent, which improves the color of myo-globin, and is mainly closer to the saturatedconcentration of the aqueous solution, while it caninclude from about 20 to 42 wt. % of the compound, which acts as an agent that improves the color of the myoglobin. An aqueous solution may be directly introduced into a polymer melt, for example, in an extruder, heated to a temperature higher than 300 ° C to facilitate non-stirring to form a mixture.
If the impurity is a solution, then should be provided with means for venting vapors from the extruder; The polymeric mixture comprising an agent that improves the color of the myoglobin may: be expressed in the form of balls or directly in the form of a film. Agent that improves the color of myoglobin, may be mixed with a carrier resin or basepolymer to form a masterbatch. The balls from the masterbatch may be suitable for further use in order to produce the products. Bubbles from the masterbatch can then be mixed with the base polymer or with another in the polymer during the film forming process.
When used for the purpose of creating a matrix mixture, a sufficient amount of solution can be introduced into the polymer melt to obtain a mixture with a high concentration of a colorimiglobin-enhancing agent, for example from about 2 to 10 wt. % of the compound improving the color of the myoglobin, and preferably from about 4 to 6% by weight.
Single layer barrier films
In one embodiment, the invention provides single layer packaging oxygen barrier films containing a food contact layer and one comprising an agent that improves the myoglobin color. The agent can be applied to a surface of a single-layer film, or it can be contained in it, for example, during the process of ex-truism. Such a film creates an oxygen barrier and may have an agent that improves the color of the myoglobin that is applied to it or injected into it.
Multilayer barrier films
Multilayered oxygen barrier films having an agent that improves the color of the myoglobin that is in contact with the surface of the meat product may, as it is desirable, contribute to the formation of a moderate red color of the myoglobin, to preserve this color, or to amplify it.
According to one aspect of the invention, the agent that improves the color of the myoglobin-bin is introduced into the contact layer with the foodstuff, which is preferably a compartment layer. In multilayer films, one or more additional layers may be used to provide useful film properties. Multilayer films have increased flexibility in their use in relation to single-layer films due to the fact that special layers can be created for the introduction of
marked distinctive features. Sometimes materials that may be unacceptable in themselves may be used predominantly in a multi-layered structure. For example, ΕνΟΗ possesses oxygen barrier properties, but is rather susceptible to moisture and is exposed to its harmful effects, however, when protection from contact with moisture is provided by means of adjacent moisture-barrier layers, ΕνΟΗ allows to obtain a film that perfectly creates a barrier for oxygen Ki-seventh layers may be arranged in a layer of abrasion resistant, or a layer resistant to improper handling, and a layer for contact with the food product and containing an agent that improves the color of the myoglobin, to protect the barrier layer and the possibility of use more thin oxygen barrier layers. When barriers are used by ΕνΟΗ, It should be assumed that in contact with material ΕνΟΗ, as an option, there may be a layer containing polyamide. Non-limiting examples of various preferred configurations of multilayer films include the following layers:
resistant to improper handling (top-of-the-line) / oxygen barrier / contact with foodstuff and sealing (internal);
resistant to mistreatment (top-of-the-line) / medium / oxygen barrier / medium / compacted (internal);
resistant to mistreatment (top-to-bottom) / binder / mid-

Preferably, all seven layers have been obtained by co-extrusion, but they can also be formed by dispersion coating, emulsion coating, dissolution, coating or layer formation, for example, extrusion layer-shaping, thermal layer formation, adhesive layer-layer formation, layeredformation with dry clutch, layer-shaping without solubility, layer-shaping-by-drawing, or extrusion application, orby their combination.
The first binding layer 112 promotes adhesion or provides adhesion between layer 102 resistant to improper handling, which is a top layer 32, and an average polyamide layer 104. Similarly, the binding layer 116 promotes adhesion or provides adhesion between the second polyamide layer 38 and the contact layer 122 with the food product, which is the inner layer 34.

Form-forming films
Thermoformed multilayer films and films are used for the formation of containers resistant to food sizes or other products. Constructions or containers are made by softening the part of the film by heating, deforming the softened film to give the desired shape and cooling the film to obtain a frozen form. Of course, hot dogs are packed in containers made of thermoformed sheets. The thermoformed films described herein can be used in accordance with the present invention by introducing a myoglobin-enhancing agent into the inner layer that is to be contacted with the food product.
The thermoformed films can be manufactured using single or common extrusion using a flat head, single or common extrusion for slit casting, or joint extrusion to blow a single bubble. Films made with these processes may be non-orientated or oriented by means of extension or lengthening of the pu-zirya to such an extent that it ensures the possibility of further implementation of the orientation / stretching.

Food packaging
In yet another embodiment of the invention, apple-forgings are prepared for food products containing fresh mycelial food containing myoglobin. Packages for food products preferably include a polymer film containing an agent that improves the color and oxygen barrier.
Fresh meat product may be any meat suitable for human consumption, which includes a myoglobin-containing molecule. By exerting a total myoglobin in meat, it is supposed to include in them any structure that contains myoglobin, including any ligand present in the structure of myoglobin (e.g., deoxymioglobin, oxymoglobin, methymogonin, car- bauximeoglobin and oxide-nitrogen myoglobin). It is important that the level of myoglobin in meat products be sufficient to ensure or maintain the desired appearance or color. Pieces of acceptable meat dispensing include yarrow, veal, pork, mutton, lamb, poultry - chicken, turkey, duck, goose, and also game, fish and seafood.<sup>1</sup> In various types of meat products, the concentration of myoglobin varies, but it is preferable that the content of myoglobin in the meat product is sufficiently high to provide the desired color when about 50% of the structure of the myoglobin in the meat will be converted into a state of communication - the formation of a ligand that provides the desired color.Of course, beef contains about 3-10 mg of miogoblin per gram of meat, pork contains about 1-3 mg of myoglobin per gram of meat, and the chicken contains less than about 1 mg of myoglobin per gram I will The concentration of total myoglobin compounds in the meat product can be, for example, from about 0.1 mg to 25 mg of myoglobin compounds per gram of meat. It is of the utmost importance that the concentration of total organophosphate may be from about 3 to 20 mg per gram of fresh meat. In other options, the concentration of total compounds of myoglobin can range from about 1 to 5 mg per gram of fresh meat. In yet another embodiment, the concentration of total compounds of myoglobin can be at least 1 mg per gram of fresh meat. In the case of one variant, the concentration of total compound hydrochloride is less than 1 mg per gram of fresh meat.
It is desirable not to be subjected to heat treatment
Meat product was the fresh meat product,
which is stored at such a period of time after slaughter,

which allows for the desired level of freshnessand safety. Preferably, the myoglobin-containing food product is packed less than 20 days after slaughter, and more preferably less than 14, 12, 10, 6, 5, 4, 3, 2, or 1 day. Of course, the harvested product is fresh meat packaged for about 2 to 14 days after slaughter, and most preferably from about 2 to 12 days.
Usual meat contains moisture (water), protein andzhir. Fresh meat can contain from about 60% to 80% moisture, and in lean meat, the content of the vogue is usually even greater. In fresh meat products such as beef, chicken and minced meat, the moisture content is from about 68% to 75%, which depends on the content of fat in the meat (meat with a higher content of fat tends to be less moist moisture and vice versa). Canned meat often has a higher moisture content due to the forging of preserved compounds on the basis of water. Products in the form of sausages may have a reduced moisture content. For example, the moisture content of the swine may be about 40% or higher. It is important that in the packaged meat products the moisture content is at least about 5%, 10%, 15%, 20%, 30%, 40%, 50%, 60%, 70%, 80% or more.
The food packaging preferably includes a polymeric oxygen barrier film containing an agent that improves the color of the myoglobin, but it may also include a film coupled to a food product having a surface that is swollen with a myoglobin-enhancing agent prior to packaging. Food packaging may additionally contain an oxygen barrier layer as part of a film forming such a package. The oxygen barrier layer may contain any suitable material and in a multilayer form, it will safely be located between the top layer, resistant to mistreatment, and the inner layer for contact with the food product. The barrier layer , may be a copolymer of ethylene and vinyl alcohol (Euon) or lyulinidhenchloride (RUCUS). Gazobar ' An overlay for packing the food product described above with reference to multilayer packaging films. One or more bonding layers may also be provided. The binding layers of the packaging for food products are described above with reference to multilayer packaging films.
Preferably, the packaging for foodstuff is a meat product in a finished shell containing a fresh meat product that includes myoglobin.
Meat products in the finished shell, in general, can be defined as fresh meat that is packed upward, which, as an option, in a centralized place is pre-applied with a label, and which is supplied to the retail market prepared for a final sale. More and more meat products, such as ground beef, native and chicken products, are supplied to retail outlets in supermarkets in the United States in the form of ready-made vagas. In many supermarkets, mainly in the so-called "ba-potash mega stores", meat products in the finished
shells not only provide cost savings
Bov, obtained by minimizing it
or eliminating the cost of performing on-site
packing and packaging, but improving sanitation
and reduce the likelihood of product damage.
Packing a product that preserves the desired coloring matter, especially fresh meat, can contribute to the availability of meat products for sale and its attractiveness for customers. In order to meet the increased requirements for meat products in agglomerates, it is preferable that they provide a given mass and / or volume of common meat products, such as chicken or chicken breast. The meat product in the finished shell may include a polymer film for preserving freshness, for example, a film described herein. The meat product may be supplied fresh, frozen, strongly cooled, defrosted, reinforced, treated or subjected to heat treatment, with the film predominantly providing Protect at different temperatures. The choice of a film for the packaging of food products may include consideration of criteria such as bar ' Properties, cost, durability, resistance to piercing, resistance to cracking at bending, compliance with food packaging rules, for example, approved by the US Food and Drug Administration (UAC), processing, optical properties such as glue and turbidity, suitability for printing, strength of seal, shrinkage, shrinkage strength, hardness and durability. A package that allows you to keep the desired color of the meat can promote the availability of meat products for sale. Moment of compactness, shrinkage, shrinkage strength, hardness and durability. A package that allows you to keep the desired color of the meat can promote the availability of meat products for sale. Moment of compactness, shrinkage, shrinkage strength, hardness and durability. A package that allows you to keep the desired color of the meat can promote the availability of meat products for sale.
According to another aspect, the packaged food product includes fresh meat that contacts a thin plastic film containing an agent that improves the color of the myoglobin on the contact surface of the product and extends the pinch of foam material supporting the product. The film is preferably is a multilayer membrane that is sufficiently oxygen-tight and so the color of the meat can be preserved with the provision of the desired color (for example, red) for more than three days, and preferentially for 5, 7, 10, 15 or more bers. It is important that the meat product is packed in vacuums containers, for example, in shrink wrap or shrink bags or bags, molded packages, trays or clogged membranes that are sealed-not by vacuum and prevent the contact of oxygen with meat ,
In certain cases, the use of ready-made shells, meat products are sometimes packed in a modified atmosphere ("IDA"), while the meat is stored in a sealed package containing free space over the product with an atmosphere that differs from; the surrounding air. Thus, it is possible to store red meat in carbon dioxide with a fairly low oxygen content, for example, in packagings where the main packaging is subsequently opened and the individual packages contained therein are pro-
67

Some oxygen films are exposed to the atmosphere, so as to provide red colored meat. In addition, the provision of a better color of the mousse can be promoted and can be supported by the use of IDA, which has a higher oxygen content. Similarly, IDA, which has a small concentration of carbon monoxide (CO), can be used to ensure and preserve the predominant red color of fresh meat. Also developed methods for processing fresh meat meat oxide carbon to packaging for cases packaging in the finished shell. The bright red complex of CO-myoglobin is called kar-bauximeoglobin. The presence of carbon monoxidecanappropriately affect the possibility ofdeals to buyers of meat products containing CO.
It can be assumed that the present invention can be used in conjunction with IDA. For example, vapors in the form of a tray in which the film contacts with a significant part of the visible surface of foodproduct, but not with all this surface, atmospheres containing CO, can be used toprovide the desired color in those areas of the upper product, which are not in direct contact with the packaging film. This variant can be advantageously used, for example, in some types of wrapper tray and packaging with a tray where the film can usually contact the top surface of the food product, but not in all locations along the side, or in packages with a petty or without a tray unevenly formed individual objects in the presence of gaps between adjacent surfaces of meat, which, for example, may occur in the case of such products,
Food packaging usually consists of a multi-layer polymer film. Packings preferably comprise one or more polyamide middle layers in contact with the oxygen barrier layer of the first variant of the multilayer strontium Euon polyamide. Food packaging products may include a three-layer oxygen barrier formed from the EuO layer in contact with the first polyamide layer on one side and a second polyamide layer on the opposite side. Food packaging may also include a heat-resistant layer, a sealing layer, one or more adhesive layers having any acceptable composition as described in the second embodiment. The polyamide layers that are in contact with the barrier layer of Euone may or may contain, in fact, a polyamide or a polyamide composition as described in relation to the first embodiment.
Preferably, a heat-resistant layer may contain, or that it actually contains a mixture of amorphous neodymium copolymer, low temperature polyamide and high-temperature polyamide. The glove-free layer is preferably placed near the outer surface of the packaging film or near it, while it may be an upper
layer, and also can form a polyamide layer. In some embodiments, the food packaging may further comprise a sealing layer located near or near the inside of the package, such as an inner layer. The packaging layers for the foodstuff are described above in relation to the multilayer packaging films.
The sealing layer is preferably located at the inner surface of the package or folded from it, for example, as an inner layer. Adhesive layers can also be introduced between; a heat-resistant top layer and a first polyamide-a-layer or between a sealing layer and a second polyamide layer. In some embodiments, the packaging for the food product may be a package for heat treatment in it, and most preferably when the packaging contains a sealing layer formed from a material that is compatible with the heat treatment conditions.
If desired, food packaging may be shrink-wrap. Packages are important to include a multilayer component that creates an oxygen barrier, and if they are thermosetting, they have a total free shrinkage, measured at 90 ° C, which is at least 30%, 40%, or 50% in at least one from the machine or the transverse directions. Packages for foodproducts preferably have free shrinkage, which is at least 30% at 90 ° C in one direction, and more preferably - at least 30% in two directions, with each direction being either the machine direction or the transversedirection. Even more and more, if the packaging for food products has free shrinkage, which is at least 40% in the first direction and not less than 50% in the second direction. Preferably, food packages are oriented to two axes or are shrink-wrapped, or both orientated on two axes, and ter-shrink. It is preferred that the packages have a full free shrinkage at 90 ° C, which is at least 80%. For example, food packaging may have free shrinkage at 90 ° C from about 80% to 120%. In some embodiments, the packaging may have total free shrinkage at 90 ° C, which is at least about 90%, more importantly, at least about 95%, and even more advantageous, at least about 100%, and even more preferably at least about 105%.
Food packaging preferably contains at least one heat-resistant layer, which may comprise a mixture of a copolymer of an amorphous nylon, a low-temperature polyamide, and a high-temperature polyamide, or is actually made up of this mixture. The heat-resistant layer may be located near or near the outer surface of the packaging film, and may represent a top coat. The heat-resistant layer can be oriented on two axes. In some cases, five-layer heat shrinkable and heat-resistant packages or packages for food products that can be formed from multilayer films by common extrusion can be created. Packages for food products can also be formed with
69
96258
70
seven layers, which may be thermoshrinkable or non-shrinkable and heat-resistant films, coated with a common extrusion. In some variants, the shrink wrapping for a foodstuff can be a package for conducting in it heat treatment, and mainly when the packaging does not contain a sealing layer. "Forging for heat treatment" is a term used to indicate a film or bag in which the food product is heat treated or pasteurized. Such a film or bag is used to co-hold and protect food products and / or to provide them with the form of those who handle food (by the manufacturer) during the cooking or pasteurization process, after which the film can be removed (sometimes a rumor -reate "zander"), or it can be left as a protective barrier during transportation and,
Here we can assume the implementation of packages for food products formed from multilayer films having from two to fourteen layers, each layer being selected from the group consisting of layers containing a heat-resistant composition with a nylon mixture, adhesive layers, layers create an oxygen barrier, moisture-barrier layers, bulky layers and sealing layers. Preferably, the top layer surface comprises a nylon mix composition having an amorphous nylon copolymer and a low-temperature polyamide. It is also important that the layer that provides the inner surface is a sealing layer.
Consider Fig. 5, which is a schematic view of the transverse section of the tray 50 containing meat. The tray 51 has a bottom part 52, one side having side walls 52a and 52b, which holds for retail sale a cut piece of meat 53, for example, from pork. The film 54 densifies the upper portion of the tray 51 and ensures a sealed seal 55a and 55b everywhere along the continuous flanges of the side walls 52a, 52b. The film 54 is sealed either under vacuum or in an altered atmosphere, with the surface 57 which is in contact with the food product and contains a myoglobin-enhancing agent, is in direct contact with the meat surface 58. The surfaces 59a and 59b of the side of the meat are not in the contact with the layer 57 and are instead subjected to the influence of the atmosphere 56, altered by gas, for example, carbon monoxide.
Now, let's consider FIG. 6, in which a representative view from above the packaging 62, with the food product 63 containing the myoglobin, for example, a piece of meat with the bone inside it, is located on the substrate and is covered with a packing film 64 as a vacuum sheath; which has a surface that is in contact with meat, which is applied to an agent that improves the color of the myoglobin. Prozor's film for the possibility of perceiving the color and character of the surface of the meat.
Now, let's consider FIG. 7, in which a schematic schematic view of a cross-sectioned container 70 containing meat, wherein a piece of fresh meat 71 containing myoglobin, is located in a thermoformed package72 that is heat-sealed relative to a non-oriented film 73 around a piece of meat near the thermal seal 74a that is continuous is connected to a thermal seal 74b to form a sealed vacuum package having an atmospheric atmosphere with a reduced oxygen content at a tightcontact between the surfaces of the film 72 and the film and 73, which contain an agent that improves the color of the myoglobin.
Packing in a vacuum shell
Vacuum packing (νδΡ) is another method well known in the art, which uses a thermoplastic packing material to cover the product. Different devices and methods are described in U.S. Pat. Nos. 3,835,618,39,509,199 and in the reprint of 30009, all of which are Rugby specimens. The method of packing in a vacuum container to a certain extent is a type of a method of thermoforming, in which the subject to be packed, serves as a form for thermoformation. The item may be packed on a support element, a plate, solid or semi-solid, or on another bottom part, after which the retention object is passed into the chamber, where the film that is on top, drag over the heated dome, and then impose its surface object. Moving the plastic film, which is from above, is controlled by vacuum and / or air pressure, In this case, in the case of a device for packaging with a vacuum box in the inner part of the container will be pumped before the final seal of the superconducting film relative to the support. The thermoformed material can also be used both as an upper film and as a bottom support with an intermediate support for products held on the other side as shown, for example, in US Pat. No. 39,660,45.
In the case of packaging using a vacuum membrane, the product to be packaged is placed on the support element. The product is used as a form for thermoformed polymer film. However, the term "packing in a vacuum shell" (hereinafter "νδΡ") refers not only to the fact that the thermoformed film is formed around the product with the help of a vacuum or a drop in the volume of air, but also the fact that the product is packed with a vacuum, and in the volume containing the product, during the packaging, pumping out.
When performing the processes of packaging in a vacuum-mum shell, usually use a vacuum chamber with an open top. The product (on an impermeable panel from the back side, through which the vacuum can not be created) are placed on the platform inside the vacuum chamber. The upper part of the ka mers cover a sheet of film, which is tightly pressurized to the chamber to form an air-permeable coating. The chamber is pumped out, while the film is heated to its temperature
71
96258
72
forming and softening. Then the platform is lifted to bring the product to a softened film, with the air being re-introduced into the chamber, can be used around the film for its tight fit to the product.
When packed in a vacuum shell is also known to reset the vacuum and provide the possibility of the introduction of ambient air into the chamber, afterthat in the chamber was pumped out, and the product was reduced to softened bythe film film or vice versa. In this case, the thermoplastic film to a greater or lesser extent formsform the surface of the product and in relation to it, sincein the package is a vacuum created, and from the outside of the outer packaging of the air acts under the pressure of the environment, or under pressure, moreoverthe pressure of the environment.
When packed in a vacuum jacket, a solid tray, which, for example, is made of a thermoformed film to support the product, is naturally used. Transparent upper film, which, for example, is made of thermoformed film, which may or may not be oriented in two axes, is formed or imbedded around the product during the vacuum packing process. The film forms a shell around the whole surface of the product. Preferably, the layer-top transparent film in contact with the food product includes an agent that improves color. As a variant, the tray may also include a color-enhancing agent in a layer in contact with a food product. Examples of trays, films, and methods used for packaging in a vacuum coat are disclosed in U.S. Pat. Nos. 4,611,456 to O.I.I.O. et al., 5846582 MauTiMe et al., And 5916613 ZIOSKEKU III, which you will enter here using a link to them. and
Ways of packaging
In accordance with yet another aspect of the invention, methods for packaging a food containing a myoglobin are created. In an embodiment of the invention, a method for manufacturing a vacuum packaging for a fresh meat product, comprising supplying a container containing a film containing a layer comprising an agent that improves the myoglobin color, may be created, with the film substantially non-permeable to oxygen; the location of a piece of meat intended for retail trade, insidecontainer; removal of the atmosphere found in the container; ensuring the immediate contact of the transparent part of the film with the least part of the surface of the meat; sealed sealing container for covering fresh meat and preventing contact with it, which is known from the outside of the container; the creation of compact packaging, which has a fairly reduced internal level of oxygen, to promote deoxymoglobin or metiumglobin, which is favorable for the meat surface, and the corresponding purple and brown color associated with them, during the formation of oxymoglobin; storage of the packaging in a cooling state for sufficient time to reduce the activity of the meat covered in order to facilitate the formation of nitroxymoglobin on the surface of the muscle to the extent that the corresponding cohesive
the color associated with it, to ensure the visible red surface of the meat.
When performing the above-mentioned variations, a wide range of MBAs, in terms of polymers, films, properties and parameters, which are here exposed, which will be understood by skilled practitioners in this field in the light of the proposed idea, can be used.
The meat product may be packaged in a suitable packaging and / or packaging film, for example, vapors and films as described herein. Preferably, with the meat product, the surface of the packaging contacting the food product containing the improved agent of the myoglobin is in contact with the meat product. It is essential that the agent, which improves the color of the myoglobin (MVA), contacts the surface of the meat to the extent sufficient to create The desired black color, which does not predominantly penetrate unwanted depth on the thickness of the product under conditions of reduced oxygen content (this color can be manifested within, for example, 1-5 days). It is advantageous for the IBA to be on the surface of the film that contacts the food product (or on the surface of the product with myoglobin) in an amount from about 0.05, to 3, to 5, to 10 micromoles / inch<sup>2</sup> and with increments about 0.1 micromolar. Larger or smaller amounts of mW can be used, with the brightness of the color may be altered depending on the presence or absence of myoglobin. The contact liner for the food product contains an agonist that improves the color of the myoglobin, for example NO2, in an amount from about 0.001 mg /<sup>2</sup> up to 0.9 mg / inch<sup>2</sup>. In addition, the packaging should store the food product in an environment with a reduced content of oxygen, which has a reduced partial pressure gas oxygen. The packaging with a reduced volume of oxygen may contain a layer that creates an oxygen barrier having an oxygen rate of less than about 310, 200, 100, 75, 150, 40, 30, 20, 10, 5 or 3 see<sup>3</sup>/ m<sup>2</sup>/ 24 hours, measured at a relative humidity of 0% and 23 ° C. It is important that the layer that creates the oxygen barrier has an oxygen transmission rate of less than about 310 cm<sup>3</sup>/ m<sup>2</sup>/ 24 hours, measured-at a relative humidity of 0% and 23 ° C more more important - less than about 75<sup>3</sup>/ t<sup>2</sup>/ 24 hours, even more preferably less than 20 cm<sup>3</sup>/ m<sup>2</sup>/ 24 hours. In addition, it may be desirable to bring the fork with the food contained therein totemperature of about 4 ° C (40 ° B) or higher to promote the color, then the temperature can be adjusted to the desiredoptimal value for storage , transport or showcase.
In many cases, packaging, for example, in vacuum packaging, desirable packing film for food products, compacted by the action of heat. Sacks and bags can be made of heat-sealed layers. A type packaging package for a food product can include three sides, sealed under the action of the producer of the package, and one side that remains open, for the possibility of entering it product Flexible packaging containers for food products, such as bags or bags, can be manufactured using cross-
73
96258
74
th cutting of tubular billets from single-layer or multilayer film and trimming part of the tube containing the sealed end, by creating a large number of separated from each other cross-connecting seams on tubular preparation and opening by cutting the side of the tube, by applying one to another flat sheets of the film and their densification on three sides, or by bending the flat sheet and its seal on the two sides. After this, a pre-seen product may be introduced, for example, fresh, frozen, chilled, defrosted, raw, reinforced, conserved or processed meat, ham, domestic pepper, meat chopped, obtained during the initial or redistribution, minced beef and other products containing myoglobin, from the performance of the sealing seals for sealing the product in the bag. This final consolidation is mainly due to the pumping of gas (for example, by vacuum removal). Flexible food packaging containers, for example, bags or packages, can be manufactured by using a transverse seam of a tube-frequent preform from a single-layer or multi-layer film and cutting a part of a tube containing an elongated end using two spaced-apart ones from one one transverse sealing seams on tubular billet and opening by cutting the lateral side of the tube, with the help of the overlapping of each other flat film sheets and their seals on three sides, or for help bending flat sheet and its uschil-ment on two sides. The final seal after the introduction of the food product can be carried out with a clamp, but usually use a thermal sealing seam, similar to the original sealing seams, manufactured by the bag manufacturer, although the actual sealed sealing equipment may be modified. Typically roughing rods or impulse sealing devices are usually used to perform thermal sealing seams.
Film for packaging foodstuff can also be used in those options in which the trays are used, for example, as a lid film or for wrapping the tray. For packaging of poultry, for example, chicken or meat of another kind, such equipment as the Oxide Polymer Container Seals, Rocky Mountain, North Carolina, USA, or Raspipe, Ips., Woodstock, Georgia may be used. , USA. As an option, packaging with the use of trayscan include the replacement of the gaseous mediumin the package of one or more gases toprovide some benefits, for example, relative to the promotion of product conservation: but forpreferring the most beneficial results due to dan the invention of at least part of the film, which creates an oxygen barrier,
surface of meat with fixed color through
transparent part of the film.
Accordingly, at least 10%, more preferably at least 20%, and even more preferably at least 30% or 50% or more of the surface of the film creating the oxygen barrier, is transparent for the visual evaluation of the color of the edible product after it is packed through it. We can assume that meat that has a bright red color, apparently to a greater extent and ensures greater clarity of the difference in physical topography, structure and changes in the color of the meat, for example, as it is determined in the case of execution finishing under marble. It can also be assumed, but not limited to the idea that light components of the muscle, such as fats, skin and light muscle fibers, will be more pronounced due to the proximity of the myoglobin, due to the agents that improve the color of the myoglobin, which fixes the bright red color , which is opposed to the purple, blue or brownish colors. In this way, the white parts look more white-me in the poultry and other types of meat, including beef and pork. This, in turn, allows buyers to get a clearer idea of the surface of meat, which increases the confidence of the buyer when purchased in comparison with meat, which has worse characteristics that are related to the appearance of the surface.
EXAMPLES
Below are examples and comparative gadgets.
The results of the experiments and the authorizations relating to the examples presented below are based on the following methods of tests or on actually similar methods of testing, unless otherwise indicated:
the velocity of gaseous oxygen passing (O2 STP): LZMP I-3985-81;
the rate of penetration of water vapor (MTUR): LZTM R 1249-90;
size: LZTMU-2103;
Melt index: AZTM Ү-1238, Condition E (190 ° C) (except for propane-based polymers with content C3> 50%), tested under the TEC conditions (230 ° C));
melting point: AZTM Ү-3418 at a heating rate of 5 ° C / min.
The values of shrinkage: the value of shrinkage is determined as the values obtained by measuring the free shrinkage of the sample area of 10 square centimeters immersed in water at 90? C (or at the specified temperature, if different) for five seconds. The four test pieces are cut off from the given sample of the film subject to the test-tion. The samples are cut in the form of squares with a length of 10 cm in the machine direction and 10 cm in the transverse direction. Each sample is completely immersed for 5 seconds in an aqueous bath at 90 ° C (or at a pre-set temperature, if it is different). Then zra-zok is removed from the bath and measure the distance between ends of the stable sample, both in MN, and in the MN. The difference of the measured distance for the standard sample and the original 10-centimeter side is multiplied by ten, so that the percentage of shrinkage for the sample in each

direction. The shrinkage of the four specimens is averaged to obtain the value of shrinkage of this sample film in MH, as well as shrinkage of the four specimens all-round to obtain the value of shrinkage in PN. The term "shrink film at 90 ° C" herein refers to a film having a free shrinkage of at least 10 % in one direction.
Shrinkage force: The film shrinkage force is the force or tension required to prevent the film from being shortened, and it is determined by the pre-assimilation of samples taken from each film. Additionally, four samples of the film are 1 "wide (2.54 cm) and 7" (17.8 cm) in the machine direction, and 1 "(2.54 cm) in length and 7" (17.8 cm) in length. in the pop-river direction. Determine and record the average thickness of the film samples. After that, each ray of the film is fixed between two clamps located at a distance of 10 cm from each other. One clamp is in a fixed position, and another clamp is connected to a strain gauge voltage sensor. Then fixed zra-zok films and clips immersed in a bath with silicone oil, held at a constant elevated temperature for a period of about five seconds. During this time, the power of the graphs is recorded, which is manifested by the strain of film shrinkage at elevated temperature. After the end of this time, a sample of the film is obtained from the sheet and provides its cooling at room temperature, immediately after which also write-in force in grams at room temperature. In addition, the force of shrinkage of the film sample determine the equation given in the following equation in grams per milliliter film (g / mil).
Shrinkage force (g / mil) = P / T, where G is the force in grams, and T is the average thickness of the film in mill.
With respect to other acceptable tests, reference can be made to the following documents, which are herein incorporated in their entirety: USSer application. No. 09/652591, entitled "Irradiated Film, Focused on Two Axes," Zossi Ibiaz, and US Patents 6777046 and 5759648.
The following are non-limiting examples of the compositions, films, and packages poured here. In all of the examples given below, unless otherwise indicated, the film compositions are usually created with the use of the device and method described in US Pat. No. 3,455,444 to the United States Patent No. 3456044, which describes the use of a double bubble method, as well as in accordance with the above detailed description . All percentages, unless otherwise indicated, represent weight percentages.
Single-layer and multilayer tubular films are made by means of the orientation process by dilution along two axes. There can be developed films with five or more layers. Multi-layer films containing the features of the invention may include additional layers or polymers for addition or variation of the various properties of the desired film, for example, heat sealing, sticking layers to one another, sticking to the surface of the food product, shrinkage, force shrinkage, shrinkage resistance , resistance to pro-
scratching, printing suitability, shockwave, gas and water barrier properties, abrasion resistance and optical properties, such as gloss, cloudiness, lack of lines, strips or thickening. These layers can be formed using any suitable method, including joint extrusion, coating using extrusion and lamination.
EXAMPLE 1
The solution of the desired colorimetric (MVA) providing agent, as described above, is prepared by dissolving the corresponding amount of such an agent in a solvent. Accepted by the concentration of the color-enhancing agent is approximately 0.60 mole of the agent in 60 grams of the solvent. The solution is prepared at room temperature by gradually mixing the mixture of solvent and MVA.
(a very low density polyethylene). The ΑΤΤΑΝΕ® 4201-C (obtained from IsoodSpetisaI Sotrapa, MibiapB, MI) is loaded into a buckler of a gravitational dispensing unit, which is used to feed the polymer into the main supply opening of the extruder ΑΡν Ehigizioz Zuizet MR2050 from a 50- millimeter, rotating in one on-line with double screw. The feeder is designed to provide an ATHENS dose of about 41 kg / h. The mixing elements of the extruder with a dual screw are located in such a way as to ensure the supply and smelting of V ^^ P, injection and mixing of the solution consisting of solvent and mVa, solvent removal, pressure increase in the head and formation of continuous passes from homogeneous mixture V ^^ PPE / MVA.
An extruder with a double auger is heated electrically, with the feed zone at 200 ° G, and the other part of the extruder - at 330 ° G. When the extruder zones reach the given temperature, the drive motor is introduced into the clutch for the rotation of the screw extruder at a speed of about 578 rpm. V ^^ РЕАФТΑΝΕ are dispensed into a main vent hole at a rate of 41 kg / h. As soon as a stable, homogeneous extrudate is obtained, a mixture of solvent and colorimetric enhancing agent is introduced into the molten V ^^ P through the inlet. To feed the opening of the dilution, consisting of a solvent and an agent, which improves the color, use a gear shaft. The inlet is located in the area of the ex-laborer, which is designed so that it has a large free volume and low pressure. The rate of filing the solution is calculated by changing the time mass of the mixture from the solvent and the agent, which improves the color. The expected concentration is close to 5% achieved by adjusting the speed of the pump. Acceptable speed of the pump is about 33 rev / min. The rate of delivery of the rose factor and the agent, which improves the color of myoglobin, is about 5.4 kg / h.

In the near-by-direction migration, the free-throttle chokes are used.
After the injection, there is a rapid rise in the temperature of the solution, which forms a reducing agent and an agent, which improves the color of the myoglobin. The solution of the solution that forms the solvent, and evaporates and eventually boils. The resultant solvent will be isolated through an outlet open at an atmospheric pressure. Some of the solvent may also be dispensed through the main supply well. After the mixing section, the mixture of VARO and MVA is shifted to the area of pressure increase, and finally comes to the head with 8 holes to create the trash. When leaving the head, the resulting continuous ribs are cooled in an aqueous bath. At the outlet of the combustion bath, the air nose removes some moisture, which adheres to the surface of the belt. After the exit of the cat-som from the influence of an air knife, they cut the desired granules using a granulator type rotary knife. These granules then dry the conventional furnace at about 50 ° C, pack the foam containing aluminum foil, and store for use, while they are called matte granules. Non-limiting examples of different technologies for the preparation of masterbatches are described at the same time in the US application Ser. No. 11/408221, entitled "Methods of introducing additives for polymer melt," Nitzier, etc., incorporated herein by reference.
Films are made of uterine granules. Rhythm of the loading of the mother-of-pearl granules is changed to create a film with VARGE with an effective concentration of the agent, which improves the color, and the packaging is made using the film of the inner layer. Food products, in particular, meat products, are packed inside the packages with the formation of vacuum and observe them for a specific period of time.
EXAMPLE 2
The use of mother-to-beads in accordance with example 1 with a basic polymer in the form of UBOREAATHNA 4201 for the manufacture of an internal layer of thermoformed multilayer film. Film is a layer of 85% nylon 6-15% nylon 6I / 6T (11% weight) / binding layer (20% weight) / layer of 85% nylon 6-15% nylon 6I / 6T (8.5% weight) / layer of EOON (9.4% weight) / layer of 85% nylon 6-15% nylon 6I / 6T (8.5% weight) / binding layer (20% weight) / layer of 70% YOUNG - 30% Masterbatch (22.6% by weight). The film is made by the method of dressing for a single bubble to create a non-Orion-hardened thermoformed film.
EXAMPLES 3a, 3b and 3c:
A bull was killed and three days after the slaughter of its meat was formed, a jagged lobar part was formed. Approximately five pounds of this truncated porcine part were put in portions of smart bags, while the meat was flattened to a thickness of 0.75 inches. After 7 days of storage in a chilled state, the meat was cut in the form of rectangular samples of 2.5 by 3.5 inches. For the example For a diet pill of 300 mg, vyigo-transpired Uiiatip MogIS containing 10 mg nicotinic acid in combination with dicalcium phosphate
cellulose, vegetable stearic acid, silica and vegetable magnesium stearate was placed on one of the samples of meat, after which the zra-zok was packed in a shell on a machine MIiUasT200, and using a film for packaging a waxy shell obtained on the basis of polyolefin and has A layer of Euon to create an oxygen barrier and a layer of polyethylene to contact the food product. The provided color of red meat began to spread from meat that is located near the tablet, after 24 hours of storage in a cooled state.
For example 3b, a second rectangular sample of the lowered shoulder blade was sprayed with an aqueous solution of niacin and packed as described in the example of Po. A solution of niacin was obtained by dissolving a similar niacin tab-medication in water. The provided red color appeared on the surface of the meat sample. However, the brightness of the red color was less than the brightness of the red color formed around the tablet.
In the case of Example 3c, the control sample was created by packing the third sample of the formed cut beef as described above for Example Po, but without the addition of niacin. The color on the surface of the sample remained burgundy without the formation of a red color, which could be seen in examples 3a and 3b.
All three packages made in Examples 3a, 3b and 3c were opened and inspected after 15 days of post-packing. After opening the packages of colored olives in each package was an even red color. Heat treatment in an open grill for roasting with gas resulted in the preparation of three samples that did not differ from each other. Inside the shiny color of both processed and untreated specimens had a pink tint.
EXAMPLES 4a, 4b and 4c
The lumbar spatula containing approximately 5% visible fat was crushed 4 days after slaughter; The chopped meat was put in a pair of flexible bags that create an oxygen barrier and packed in a car with a Coca chamber. The color of the meat was converted from red to dark purple within 4 hours. In the case of Example 4a, after 24 hours of storage in a cooled state, one of the vacuum packets with a split loofah was opened, and a portion of the meat was mixed with niacin to obtain a grated chicken containing 0,025 wt. % niacin. Then this mixture was placed on white polypropylene fiber, which creates an oxygen barrier, which holds the barrier layer of Euon. Similarly, in the case of Example 4b, the rest of the packaged meat was opened and placed on a tray of the same type without any addition of niacin. The jagged split blade part was wrapped in a vacuum jacket on a MIiUasT200 machine using a film to pack a spontaneous oxygen barrier shell (U5P), which appears as a barrier to the Eunon. In the case of example, 4 more than one part of the packaged meat was opened and placed on a tray without any addition of niacin. After that the tray was packed on a ma-

MiShouAs T200 bus with UZR film containing a 2% sodium nitrite weight seal. After 24 hours of cooling in a cooled state, niacin-treated meat, Example 4a, was dyed to a predominantly red color, while at the same time as an untreated sample of meat, Example 4b, showed a dim purple color character of the fresh m ' Gida packed with the help of the vacuum. Meat on the third tray with a film containing nitrite, example 4c, gained a grayish-purple color for the first 24 hours, after a color turned into a bright red color.
The color of the meat processed by niacin was darker than the meat in the package with a film containing nitrite. The lower side and central parts of the meat treated with niacin had the same saturated red color as the surface. Red colored colourants in a film containing nitrite penetrated blizko 1 / 16-1 / 8 inches from the surface of the meat.
After storing in a refrigerated state for 1 week, all three samples of meat were unpacked. Subsequently, samples of meat were placed on an open grill for frying with gas. They were subjected to slow heat treatment at 200-250 ° E approximately in 45 minutes with turning-on every 5-10 minutes to achieve the optimal level of heat treatment. The color of the heat treated subjects and the internal parts of the meat made by niacin, packed in UZR of oxygen-jet film, and raw meat packed with UHF oxygen barrier film, was the same. The red color continued to exist on the visible top of the surface of the meat that is in contact with a film that has no added niacin, which was packed in a film containing nitrite, Example 4c, with the same depth of penetration that could be observed in the crude product .
EXAMPLE 5
The powder of nicotinic acid (obtained from ZIDdta AISgISP SpetIsaI Sotrapa, MIdiAaykee, AI) was mixed with granules UBORE Oom ΑΤΤΑΝΕ®4203 (0.5 decigram / min, 0.912 g / cm<sup>3</sup>; copolymeretylene and octene obtained from Oom SpetIsaIstrap, MibiPap, MI) by mixing in the drum until the powder evenly covers the surface of the granules. The number was chosen so that the contents of the nicotinic acid glass was about 5 wt. % (14.25 kg DOS and 0.75 kg nicotinic acid). The mixture was loaded in a bunker of a gravitational dispensing unit, which is installed in such a way as to feed the polymer into the main cavity of the extruder AGC Exigentio ZuzietMR 2050 with a 50-millimeter dual screw that rotates in one direction. The feeder is designed to provide a pre-fed supply of nicotinic acid and UBOREZ at a rate of about 36 kg / h. Mixing elements of an extruder with a dual screw compound-
in such a way as to ensure the supply of a mixture of nicotinic acid and VARGE, intensively mixing nicotinic acid to penetrate it in the DOMAIN, with the formation of pressure at the head and the formation of continuous cones of homogeneous mixture.
An extruder with a dual auger is electrically heated, so that the feeding zone is at a temperature of 200 ° E, and the other part of the extruder is at a glance of 320 ° E. The metered supply to the main cavity hole of the nicot-new acid mixed in the drum and WORD is about 36 kg / h. As soon as a stable homogeneous extrudate is obtained, continuous strands are cooled by their passage through an aqueous bath. On the way out of the water pool, the air knife removes moisture that adheres to the surface of the belt. After the passage passes from under the influence of an air knife, they are cut into separate granules using a rotary knife type granulator. The resulting pellets have a slightly reddish-brown color. At the end of the time at the output of each of the heads of the holes you can see the accumulation of powder.
EXAMPLE 6
Repeat Example 5, except that nicotinic acid is replaced by nicotinamide (retrieved from ZITA AIBgIsP SpetIsaI SotrAp, MIdiAaikee, MI). It can be seen that the resulting gametes have a brown color.
EXAMPLE 7
Repeat Example 6, except that the speed of rotation of the screw extruder is reduced to about 200 rpm. The tablets have a fairly bright yellow-brown color, and their surfaces have a high gloss. Strengths are stable, and the efficiency of production is much higher compared to example-house 6.
EXAMPLE 8
Repeat Example 5, except that the speed of rotation of the screw extruder is reduced to about 200 rpm. As in Example 7, the color of the game-zero is much lighter. The rate of growth in the flush over the head openings is much lower than the joints, which are fixed in example 5.
All polymers according to Examples 5-8 containing MBA can be used to form containers suitable for packaging a myoglobin containing food product to maintain the desired surface color in it.
In films, bags or packages, the combination of characteristics described in one or more embodiments may also be used.
The above examples are only illustrative and should not be considered as imposing restrictions, since in the light of the proposed idea of the invention, for the skilled specialists in the art, additional modifications to the options disclosed herein will be apparent. It should be assumed that all such modifications should be in the scope of the options discussed here.
