Problems solved by technology

At present, most of the bioactive peptides of giant salamander are prepared from the muscle, skin, viscera, fat, and blood of giant salamander through enzymatic hydrolysis and separation. Active peptides with different functions can be obtained by using different separation techniques, but most of them have a single function
So far, there is no relevant report about giant salamander active peptides that can scavenge free radicals, improve the body's immunity and promote the growth of skin fibroblasts

Abstract

The invention discloses a giant salamander active peptide and an application. The giant salamander active peptide is prepared by the following steps: conducting enzymatic hydrolysis on giant salamander meat which serves as a raw material by virtue of a complex enzyme of marine alkaline protease and papain; separating an enzymatic hydrolysate by virtue of a trypsin immobilized ultra-filtration membrane separator; and then conducting separation and purification by virtue of Sephadex LH-20 molecular sieve chromatography and high performance liquid chromatography, so that the giant salamander active peptide is obtained. The giant salamander active peptide is capable of effectively scavenging free radicals and boosting body immunity, and meanwhile, the active peptide can also promote proliferation of skin fibroblasts; therefore, the giant salamander active peptide has a broad application prospect in the fields of food, medicines and cosmetics.

Description

technical field [0001] The invention belongs to giant salamander products, and in particular relates to a giant salamander active peptide capable of scavenging free radicals, improving body immunity and promoting the growth of skin fibroblasts and its use. Background technique [0002] Studies have shown that the muscles, skin, viscera, fat, and blood of giant salamanders are rich in protein, amino acids, fatty acids, and trace elements. Deep processing of giant salamander proteins can obtain a series of bioactive peptides of giant salamanders that are beneficial to human life activities. Potential source of health food and medicine. At present, most of the bioactive peptides of giant salamander are prepared from the muscle, skin, viscera, fat, and blood of giant salamander through enzymatic hydrolysis and separation. Active peptides with different functions can be obtained by using different separation techniques, but most of them have single functions. So far, there is n...
