Preparation method of donkey-hide gelatin small molecular peptide

Abstract

The invention relates to a preparation method of a donkey-hide gelatin small molecular peptide. Donkey-hide gelatin is adopted as a main raw material, and the donkey-hide gelatin small molecular peptide is prepared by adopting the technologies such as raw material pretreatment, enzymolysis, filtration, decolorization and drying, wherein an enzymolysis process is characterized in that enzymolysis is carried out for multiple times by adopting multiple proteases, and collagen in the donkey-hide gelatin is treated by enzymolysis to obtain a small molecular peptide easy to be digested and absorbed by a human body. The preparation method of the donkey-hide gelatin small molecular peptide has the beneficial effects that a compound biological enzyme enzymolysis technology is utilized, enzymolysis is carried out by sequentially adopting alkaline protease, neutral protease and pepsin for enzymolyzing macromolecular protein contained in the donkey-hide gelatin into the donkey-hide gelatin small molecular peptide, the molecular weight of the obtained donkey-hide gelatin small molecular peptide is mainly distributed within 100-1000D, and the obtained donkey-hide gelatin small molecular peptide is mostly a small molecular peptide such as dipeptide, tripeptide and tetrapeptide, belongs to a small molecular structure and is extremely easily absorbed and utilized by the human body.

Description

technical field [0001] The invention relates to a preparation method, in particular to a preparation method of donkey-hide gelatin small molecule peptide. Background technique [0002] Donkey-hide gelatin is hard and brittle, the cross-section is bright, and the fragments are brown and translucent when viewed against light. Donkey-hide gelatin contains a large amount of collagen, as high as more than 80%. It has the functions of nourishing blood, nourishing yin, moistening dryness, and stopping bleeding. It is a good blood tonic. Most donkey-hide gelatin in the market is oral ointment in paste form. The high content of collagen is difficult to digest and absorb in the human body, especially for patients with weak spleen and stomach. Oral donkey-hide gelatin is less digested and absorbed so that it is difficult to achieve the efficacy of the medicine, and it also increases the burden of gastrointestinal digestion. Contents of the invention [0003] In order to solve the ab...
