METHOD FOR OBTAINING COLLAGEN MATERIAL IN THE FORM OF PARTICLES AND COLLAGEN MATERIAL OBTAINED BY THIS METHOD Russian patent published in 2021 - IPC A23J1/10 A23L29/281 C08H1/06 

FIELD: food industry.

SUBSTANCE: collagen- and fat-containing initial material of animal origin is subjected to extraction treatment with an aqueous extraction solution with a pH value from 3.5 to 5.5 for a period of up to 30 h. Extraction is carried out in total from two to eight times. If necessary, at least part of an aqueous phase is separated from a residue after extraction. The residue after extraction is divided into a collagen-containing solid phase, an aqueous phase and a fat phase. At least part of the collagen-containing solid phase is mixed with at least part of the aqueous phase in a mass ratio from 1:99 to 1:1. Mixed phases are subjected to at least partial drying at a temperature of 50 to 150°C. Dried phases are crushed to obtain collagen material in the form of particles. Collagen material in the form of particles has an average particle size from 20 to 250 mcm, has water absorption capacity from 1:1 to 50:1 per its own mass and/or emulsifying capacity for fat and water from 1:1 to 20:1 per its own mass. The use of collagen material in the form of particles in the production of food products, primarily meat and sausage products is also proposed.

EFFECT: group of inventions provides the production of pure collagen material in the form of particles, allows for the use of the residue after extraction formed during the production of gelatin (a significant increase in the volume of pure products from the used material of animal origin).
