Dry polysaccharides

Abstract

Powdered polysaccharide may be made by spray drying an emulsion in a non-aqueous liquid of an aqueous solution of the polysaccharide. Spray dried polysaccharides are novel materials. At least 90% by weight of the particles may be within a size range of not more than 100 microns. The particles may have an average size between 50 and 250 microns or between 10 and 50 microns, and the finer particles can be redispersed into oil.
