CHEMICAL AND BIOTECHNOLOGICAL PROCESSING OF COLLAGEN-CONTAINING RAW MATERIALS INTO FUNCTIONAL COMPONENTS OF FEEDS TO OBTAIN HIGH QUALITY MEAT OF FARM ANIMALS
The process of chemical biotechnological processing of collagen-containing raw materials into functional components of feeds for effective pig rearing has been studied. Protein components of feeds were obtained as a result of hydrolysis in the presence of lactic acid of the animal collagen from secondary raw materials, which was used as split, skin and trimmings with tendons of cattle. For comparison, a method is described for preparing protein components of feeds by cultivating Lactobacillus plantarum. Analysis of the kinetic data of the conversion of a high-molecular collagen protein to an amino acide - polypeptide mixture showed an advantage in obtaining protein for feeds by microbiological synthesis. Feed formulations have been developed, including the components obtained, which make it possible to obtain high quality pork for the production of quality meat products.
