METHOD FOR PRODUCTION OF SEA-CUCUMBER DRY HYDROLYSATE AND BIOLOGICALLY ACTIVE FOOD ADDITIVE PRODUCED BY SUCH METHOD Russian patent published in 2015 - IPC A23L1/30 A23L1/305 A23L1/33 A23J1/04 

FIELD: food industry.

SUBSTANCE: method for production of a sea-cucumber dry hydrolysate involves stages of hydrolysis of the prepared raw materials with an enzyme preparation, the hydrolysate drying and the dry hydrolysate milling into powder. Prepared raw materials are represented by sea-cucumbers carcasses cleared of entrails and milled. At the stage of hydrolysis the enzyme preparation is represented by a proteolytic enzyme preparation isolated from sea hydrobionts and having proteolytic activity equal to 3.5-15 PU/g. The weight ratio of the enzyme preparation to the prepared raw materials is 1:50-1:200. Hydrolysis is performed during 2-8 hours at a temperature of 18-35°C. At the stage of drying one uses lyophilic drying till the dry hydrolysate moisture content is no more than 10 wt %. The produced dry hydrolysate has the following physical and chemical composition, wt %: weight fraction of moisture - 7.5-10; weight fraction of crude protein - 30-52; weight fraction of lipids - 3.0-5.0; weight fraction of polyunsaturated fatty acids - 38.1-45.0, including: eicosapentaenoic acid - 12.2-17.0; docosahexaenoic acid - 2.0-6.0; arachidonic acid - 9.0-15.0. The dry hydrolysate is used as a biologically active food additive.

EFFECT: invention allows to increase biological value of dried sea-cucumber products and to reduce the cost of their manufacture due to heat treatment operations minimisation in the technological process.
