METHOD OF PRODUCING COMPOSITION BASED ON HYDROLYSED COLLAGEN (VERSIONS) Russian patent published in 2024 - IPC A23J3/34 

FIELD: food industry.

SUBSTANCE: invention relates to food industry and is used for production of food products, biologically active food additives, specialized food products. Method of producing a composition based on hydrolysed collagen involves heating mineral water with a degree of mineralization of water equal to 1,145.39 with content of silicic acid H₂SiO₃ 27.9±5.6 mg/1,000 ml to temperature 75 °C, then edible gelatine is added at ratio of 1:99-30:70 and the obtained solution is cooled to 60 °C. Enzyme preparation protozyme is added in amount of 5 g per 1 kg of gelatine, diluted to a liquid state, and hydrolysis is carried out at 55-60 °C for 4 hours with constant stirring. Then the solution is filtered twice and pasteurized at temperature of 90±2 °C for 30 minutes. Method of preparing the composition also involves drying solution at 80 °C and sieving through a sieve with particle size of 1.0 mm.

EFFECT: disclosed method of producing a composition based on hydrolysed collagen increases content of hydrolysed collagen in the composition, simplifies the technology for preparing the composition, increases the biological value of the composition and its bioavailability.
