METHOD OF HYDROLYSATE PRODUCTION Russian patent published in 2009 - IPC A23J1/04 A23J3/34 

FIELD: food products.

SUBSTANCE: fish raw materials are cut, washed and rinsed by anolyte of electrochemically activated water, milled. Reaction mixture is made by mixing fish raw materials with water and enzyme preparation. Enzymatic splitting of reaction mixture is done. Inactivation of enzyme system by heating up the reaction mixture is performed, partition of reaction mixture is done with extraction of hydrolysate, its de-fatting in the separator and drying. The process of enzymatic splitting is performed, using catholyte in quantity 30% materials weight at the temperature 55°C. To obtain hydrolizate without separation of non-enzymated protein residue, enzymatic splitting is performed 1.5-2 hours before reaching hydrolysis depth with 25-27% filtrate nitrogen of total quantity of materials nitrogen. In order to make hydrolysate with separation of non-enzymated protein residue enzymatic splitting is performed 4-6 hours before reaching hydrolysis depth with 60-65% filtrate nitrogen of total quantity of materials nitrogen.

EFFECT: reagentless creation of media pH, decrease of duration of operating practices of processing, acquisition of final product with low leach content, improvement of hygiene at the place of production.
