METHOD FOR PRODUCING A BIODEGRADABLE FILM BASED ON CHITOSAN AND STARCH FOR MEDICINE

摘要

FIELD: chemistry.;SUBSTANCE: invention relates to a method for producing a biodegradable film that retains its integrity in a physiological solution for 5–7 days in a 0.9 % aqueous solution of sodium chloride with a TRIS buffer for 20 days containing starch and chitosan, for use in pharmaceutics, medicine, veterinary medicine, food or cosmetic industry. Method for producing a biodegradable film based on chitosan and starch for medicine includes the preparation of a solution of chitosan in 2 % acetic acid and an aqueous solution of starch, mixing solutions, forming the film, drying, processing with aqueous ammonia solution.;EFFECT: reduction of solubility of the biodegradable film.;1 cl, 2 ex
