The present disclosure provides a micromolecular type III collagen peptide capable of promoting secretion of type III and IV collagens, and a preparation method therefor, belonging to the field of micromolecular peptides. The method for preparing the micromolecular type III collagen peptide comprises the steps of pretreating livestock and poultry skin, enzymatically hydrolyzing the livestock and poultry skin by using a combined enzyme and the like. The micromolecular type III collagen peptide may include any one or more of amino acid sequences shown in SEQ ID NOs. 1-8. The preparation method of the present disclosure has short production period. The resulting product has good color and smell, high recovery rate, high content of the micromolecular type III collagen peptide and a specific sequence.

Micromolecular type III collagen peptide capable of promoting secretion of type III and IV collagens, and preparation method therefor

A type III collagen peptide and a preparation method thereof are provided. The preparation method includes: degreasing a raw material, performing ultrasonic treatment and fermentation to obtain a total crude protein extract; extracting a crude collagen extract under an acidic condition; adding a clarificant to remove impurities; addingfor fermentation to obtain a type III collagen; adding a compound protease for enzymolysis, followed by inoculatingfor fermentation; and separating and purifying to obtain the type III collagen peptide. The type III collagen peptide has an average molecular weight of 300-3,000 Daltons, contains a symbolic peptide fragment of type III collagen, is safe, free of toxic and side effects, and easy to digest, can be used as a raw material of medicines, cosmetics, dietary supplements, and food, and be added into acidic beverages, and can promote generation of type III collagen in human's body.
