METHOD FOR OBTAINING PROTEIN HYDROLYZATE FROM ATLANTIC COD PROCESSING WASTE Russian patent published in 2023 - IPC A23J1/04 A23J3/04 

FIELD: food industry.

SUBSTANCE: used to obtain protein hydrolyzate from Atlantic cod processing waste. A method for obtaining protein hydrolyzate from Atlantic cod processing waste has been proposed. The method involves grinding raw materials, processing the crushed raw materials with a 0.5-1.0% solution of acetic acid or citric acid at a temperature of 15 - 20°C and the mass ratio of the raw material and the acid solution is 1:4, separating the precipitate and washing it with cold water to neutral pH values of the wash water and subsequent hydrolysis under the action of the protozyme - proteolytic enzyme preparation, taken in an amount of no more than 0.5% by weight of the original raw material, at a temperature of +60°C. Upon completion of hydrolysis, the reaction mixture is heated to a temperature of +90°C to inactivate the enzyme preparation, the resulting hydrolyzate is filtered, dried, then crushed and packaged.

EFFECT: utilizing Atlantic cod processing waste and obtaining a protein supplement consisting of biologically active peptides with a molecular weight of 30-60 kDa.
