METHOD FOR PRODUCING A PROTEIN-CONTAINING FOOD INGREDIENT Russian patent published in 2023 - IPC A23J1/10 A23J3/04 A23J3/34 

FIELD: food industry.

SUBSTANCE: method of obtaining a protein-containing food ingredient is implemented as follows. Cuts of connective tissue obtained by processing the edge sections of cattle skins are washed with water at a temperature of 20-25°C. An enzymatic treatment is carried out, where the raw material is treated in a 1% solution of protosubtilin GCl or protepsin in a ratio of 1:2. Intensively mixed in an apparatus with scraper agitators at a temperature of 33°C for 1.5-2 hours. Clarified with a 2.5% hydrogen peroxide solution in a ratio of 1:2 for 0.5 hours. Heated and held in a 0.05% sodium hydroxide solution at a temperature of 60°C for 1 hour. Cooled, filtered and dried in a drum dryer at a temperature of 135-140°C. Grinded, dried to a mass fraction of 8±2% moisture, cooled and packed.

EFFECT: increasing the depth of processing of by-products of the meat industry, obtaining a digestible form of a food protein-containing ingredient with a complete set of essential amino acids.
