Abstract

The invention discloses a method for removing oil and fat from donkey-hide gelatin peptide, and belongs to the technical field of biology. A donkey-hide gelatin peptide product is obtained by taking adry donkey-hide gelatin heap as a raw material, performing enzymolysis on donkey-hide gelatin protein by using compound protease, degreasing and decolorizing by activated carbon, combining with an ultrafiltration separation and purification method, and performing spray drying. The method for removing the oil and fat from the donkey-hide gelatin peptide disclosed by the invention has the advantages of low cost, short clearing time, less pollution, high clearing rate, simple process and no influence on various functions of the donkey-hide gelatin peptide.

Description

technical field [0001] The invention relates to a method for removing fat from donkey-hide gelatin peptide, which belongs to the field of biotechnology. Background technique [0002] Collagen is an extremely important structural protein in connective tissue, widely present in animal tissues such as bone, tendon, muscle sheath, ligament, sarcolemma, cartilage and skin. Its extracted products have been widely used in medicine, health care, food processing, cosmetics and many other fields. The main source of raw materials for collagen products currently produced is the skin, bone and tendons of terrestrial mammals such as pigs or cattle. The removal of grease from animal hides remains an unresolved problem. [0003] In the production of collagen, defatting is part of the pretreatment. Too much fat content will generate insoluble calcium fatty acid in the subsequent process, and agglomerate, seriously hindering the subsequent operation. In addition, too much oil residue will...
