FIELD: chemistry.
SUBSTANCE: invention relates to compositions of edible films which contain xanthan and chitosan. The invention is used in pharmaceuticals, medicine, veterinary, food or cosmetic industry. An edible film coating made from a thickener, chitosan, water, a solvent and glycerol. The thickener used is a microbial polysaccharide - xanthan, the chitosan solvent used is 3% citric acid solution, with the following ratio of components, wt %: xanthan - 50-55; chitosan - 10-15; water - 5-10; 3% citric acid solution - 5-10; glycerol - 5-10; 3% methyl cellulose solution - the balance.
EFFECT: invention enables to obtain a homogeneous film based on xanthan and chitosan.
