FIELD: biotechnology. ^ SUBSTANCE: method involves purification of protein raw, addition of water and ice, milling a mixture followed by hydrolysis. After hydrolysis collagen-containing solution is homogenized and collagen is separated. Hydrolysis is carried out for two stages. The first stage is carried out by treatment of the reaction mixture with lipase from fungus Rhizopus oryzae, and at the second stage a proteolytic enzyme as neutral protease is used. Invention provides preparing collagen approaching to natural collagen by physicochemical and structural-mechanical properties. Invention can be used in food processing industry, cosmetic, medicinal and other branched of industry. ^ EFFECT: improved preparing method. ^ 4 cl, 3 ex |
