Problems solved by technology

[0004] (1) Domestic cowhide raw materials generally have many kinds and miscellaneous situations. There are many origins of cowhide, resulting in uneven quality of cowhide, which directly affects the quality of subsequent production products. A lot of raw materials are wasted, and the quality of the product cannot be effectively guaranteed;
[0005] (2) Sterilization generally adopts ultra-high temperature method, which will deepen the color of the product, and will lead to the decline or even loss of the activity of the active polypeptide in the product, affecting its functionality;
[0006] (3) Activated carbon powder is generally used in the decolorization process, which will cause irreversible loss of the product (polypeptide) while removing pigment substances;
[0007] (4) The produced collagen peptide has an unpleasant smell and poor flavor

Description

technical field [0001] The invention belongs to the technical field of enzymatic hydrolysis of bovine collagen peptides, and particularly relates to a production process of bovine bovine collagen peptides. Background technique [0002] Collagen peptides are obtained by hydrolysis of collagen. Due to the smaller molecular weight, the increase of polar groups increases the solubility. After the collagen is degraded into collagen peptides, due to the leakage of a large number of hydrophilic groups, the water absorption and water holding capacity of collagen peptides are significantly higher than those of collagen. Using it in cosmetics can maintain skin moisture and improve skin moisturization. Effect. The emulsifying and foaming properties of collagen peptides also make them useful as food additives to improve the quality of food, making the products not only taste good, but also rich in nutrients. In addition to the general functional properties of proteins, collagen peptid...
