FIELD: fish processing industry.
SUBSTANCE: invention relates to method for production of chitin from raw materials belonging to class Crustacea. Claimed method includes maxillopod grinding, enzymatic hydrolysis of proteins, hydrolyzate separation followed by drying, demineralization deproteinization. Enzymatic hydrolysis is carried out by using own maxillopod enzymes. Autoenzymolisis is carried out in aqueous medium with addition of bioconserving agents in raw/bioconserving agent solution of 1:(3-4) for 21 h at 35°C. As bioconserving agent milky whey or aloe juice is used. After protein hydrolyzate separation chitin semi-product is demineralized.
EFFECT: decreased product cost, product of improved quality, environmentally friendly method.
