FIELD: food industry.
SUBSTANCE: method involves cleaning the low-value fish raw material feedstock, cutting into fillets with removing the entrails, bones and fins, grinding, hydrolysis, heat treatment, pressing with separating the press liquoor, and centrifuging with separating the protein mass and fat. Target products are extracted from each obtained fraction separately. The protein mass is subjected to drying, cooling, CO2-sterilisation, and grinding to obtain food fish meal. The fat is separated, refined and deodorized. The press liquor is subjected to concentration and enrichment. The bones and fins are dried, cooled, and ground to obtain fish bone meal.
EFFECT: invention provides the complex processing of low-value raw fish material.
