METHOD OF PRODUCING FUNCTIONAL PRODUCT BASED ON MOLLUSC HYDROLYSATES Russian patent published in 2025 - IPC A23J1/04 A23J3/32 

FIELD: biotechnology; food industry.

SUBSTANCE: invention relates to biotechnology and food industry. Disclosed is a method of producing a functional product based on hydrolysates of mussels and rapana in the form of a composition of an alkaline hydrolyzate of minced mussel meat with flaps, which are hydrolysed for 3 hours, and an acid hydrolyzate from milled rapana meat, which is hydrolysed for 20 hours, followed by evaporation of the composition. For alkaline hydrolysis, preliminarily defatted mince is used, for which mussels crushed with a flap are heated in water to 85 °C for 30 minutes with constant stirring, with separation of broth, cooling thereof and decantation of fat layer and repeated heating of broth to 80 °C, which is hydrolysed with alkali when heated to 95 °C, separating, filtering and cooling the obtained hydrolyzate to room temperature. For acid hydrolyzate used heated to 60 °C 24% citric acid solution, into which in ratio 1:1 is added rapana meat mince, hydrolysis is carried out, increasing temperature from 60 to 95 °C with constant stirring, then the obtained acid hydrolyzate is filtered and cooled to room temperature. Further, the alkaline and acid hydrolysates are mixed in ratio of 15:1 to pH 5.68, then the composition is evaporated, heating to 80 °C at vacuum minus 650 – minus 700 mbar to dry solute content of not more than 15%, and lyophilised.

EFFECT: invention enables to obtain a lyophilised composition with moisture content in the end product of not more than 6-8% of residual moisture, suitable for crushing a tablet, lyophilization and packing into hard gelatine capsules or tableting.
