Abstract

The invention discloses an extracting method for crocodile skin peptide. The extracting method for the crocodile skin peptide comprises the following steps: S1, pretreating crocodile skins; S2, cooking the crocodile skins to form primary soup; S3, discharging the soup and pumping the soup into a primary soup storage device; S4, fermenting and hydrolyzing to form enzyme-deactivated hydrolysate; S5,filtering; S6, concentrating: concentrating circularly filtered clear liquid until the concentration reaches a set value to form clarified concentrated liquor; and S7, spraying drying: carrying out spray drying on the clarified concentrated liquor according to a set air inlet temperature and a set air outlet temperature to form a crocodile skin peptide finished product. By the extracting method,small molecule peptides are converted and extracted from the crocodile skins of crocodiles which are bred artificially, the molecular weight of the crocodile skin peptide is 10000 Dalton or below, theoriginal active ingredients of crocodiles are retained, furthermore, digestion and absorption property and utilization rate are quite high, and the crocodile skin peptide is digested parenterally, and can be directly utilized by human bodies.

Description

technical field [0001] The invention relates to the technical field of crocodile deep work extraction, in particular to a method for extracting crocodile skin peptides. Background technique [0002] Crocodiles are the oldest reptiles and have survived on earth for more than 230 million years, so they are known as "living fossils". The twenty-sixth volume of "Chinese Materia Medica" contains: the Chinese alligator (Alligatorsinensis) A tablet, the drug name is Tujia, has the functions of removing blood stasis, eliminating accumulation, and killing insects. Intestinal wind hemorrhoids. Crocodile meat has the functions of strengthening tendons and bones, filling and nourishing marrow, and has curative effect on rheumatism and bone pain. Crocodile skin, meat, blood, oil, internal organs and other parts of the body are rich in protein, DHA, lecithin, unsaturated fatty acids, iron, zinc, phosphorus, magnesium and other 10 kinds of trace elements, more than 18 kinds of amino acid...
