Abstract

The invention discloses a method for preparing collagen peptide by hydrolyzing bovine bones, and the collagen peptide. The method comprises the following steps: S1, cleaning bovine bones, and freezingand preserving the cleaned bovine bones at a temperature from -20 DEG C to -1 DEG C for 3-11 hours; S2, grinding and crushing the frozen and preserved bovine bones in step S1 into bone residues; S3,adding 0.5-1.5 times of water into the bone residues in step S2, performing homogenizing, adjusting the temperature to 40-50 DEG C, then adding protease, and performing enzymolysis under a certain condition; and S4, performing enzyme deactivation treatment after the enzymolysis is finished, performing filtering by a plate-frame filter press or performing purifying refining by membrane separation,and performing drying after double-effect concentration to obtain the bovine bone collagen peptide. The technological method provided by the invention has the advantages of short enzymolysis time andgood enzymolysis effect; and the obtained protein peptide product is easy to dissolve in water, and has a high nutritional value and good dispersibility.

Description

technical field [0001] The invention relates to the field of preparation of protein peptides, in particular to a method for preparing collagen peptides by hydrolyzing bovine bone and the collagen peptides. Background technique [0002] Collagen is a structural protein of the extracellular matrix, the main component of animal connective tissue, and the most abundant and widely distributed functional protein in mammals. It is involved in the formation, maturation, transmission of information between cells, and joint Lubrication, wound healing, calcification, blood clotting and aging are closely related. In addition to the many physiological activities of collagen, collagen peptides also have properties that collagen does not have. Compared with collagen, collagen peptide, as a small molecule peptide, has a lower molecular weight and better digestion and absorption. It can be directly absorbed by the intestinal tract, enter the blood, and reach various parts of the body such a...
