Abstract

The invention provides a collagen tripeptide product, the collagen tripeptide contains tripeptide of which at least one end is alkaline amino acid, the molecular formula of the tripeptide of the alkaline amino acid comprises Gly-X-Arg, Gly-X-His and Gly-X-Lys, X is amino acid; based on the total weight of the collagen tripeptide, the content of the basic amino acid is not less than 10%. The invention also provides a method for preparing the collagen tripeptide, which comprises the following steps: adding water into the collagen to ensure that the pH value of the solution is 5-8, and adding the compound protease which is 0.5-5% of the weight of the collagen; carrying out enzymolysis for 2-6 hours at 45-60 DEG C; the compound protease comprises ficin protease and ginger protease; adjusting the pH value of the enzymatic hydrolysate to 7-8.5, adding a leavening agent accounting for 1-8% of the weight of the collagen, and fermenting at 30-42 DEG C for 2-4 hours; the leavening agent is prepared from debaryomyces hansenii, pediococcus pentosaceus and micrococcus mutans; and carrying out solid-liquid separation on the fermentation liquid, and collecting filtrate.

Description

technical field [0001] The invention relates to a collagen tripeptide product, a preparation method of the collagen tripeptide product and the application of the collagen tripeptide product in cosmetics. Background technique [0002] Collagen is an important component of extracellular matrix, and its content is about 1 / 3 of human protein, which plays an important role in maintaining the structure and function of the body. Collagen is lost as people age. At the same time, due to the low reversibility of collagen in the extracellular matrix of the dermis of skin tissue, it is more likely to undergo non-enzymatic reactions with metabolic molecules such as glucose to generate advanced glycation end products (AGE), such as glycosylated collagen, etc. A series of adverse effects on the organization. [0003] Collagen peptide is a small molecule peptide product made by enzymatic hydrolysis of macromolecular collagen. According to research reports, collagen peptides can improve s...
