DEVELOPING THE TECHNOLOGY AND EVALUATING THE BIOLOGICAL VALUE OF THE PEPTONE FROM SECONDARY PRODUCTS OF PROCESSING OF FISH RAW MATERIAL OF THE ARCTIC REGION

The results of microbiological and toxicological tests have proved the safety of the bone-muscular cod waste (BMW). Waste (humerus with meat cuts) from cod cutting on fillets contains 18,95 % of a full-grade animal protein and insignificant amount of fat (0.15 %). Thus, the possibility of using them as a protein raw material for producing peptones has been proved. The technology of obtaining peptone from the secondary fish raw material - bone-muscular waste from the cutting of cod fish - has been developed and optimized. Using the cryoextrusion method in the technology of peptone production at the stage of grinding waste is proposed. Using of the enzyme (protosubtilin G3X) in hydrolysis is substantiated; proteolytic activity is established, it is 560,77 μmol TYR / g, the optimal temperature of enzymatic hydrolysis of BMW is (45±1) ˚С.
