Method of producing morphologically uniform microcapsules and microcapsules produced by this method

Abstract

The invention relates to a preparation of microcapsule methods, wherein the microcapsule comprises as the active ingredient peptides other, or proteins of bioactive material, according to the encapsulation concentration of microcapsule the method and system results are 3-30 weights %; the diameter is less than 8 μ thereof. According to the invention, wherein the polymer dissolution of biodegradable of the non-halogen solvent or the solvent agent, and is penetrated through the upper the active ingredient a fragrant to the upper transfusion, wherein the field of cushion pH of 6.0-8.0. Is comprises a surfactant watery solution of W/O the latex (W/O/W the latex), and removing solvent. Without the agglomeration dynamic according to the capsule of the method and system of results. Encapsulation of the method rate is provided 90-95%.
