Abstract

The invention relates to a cordyceps militaris polypeptide and a preparation method thereof. The preparation method comprises the following steps: S1) drying and crushing cordyceps militaris and then adding into distilled water, cooking for 1-2h, and then cooling to room temperature, thereby obtaining a cordyceps militaris aqueous solution; S2) regulating the pH value of the cordyceps militaris aqueous solution to 5-9, and then adding a compound enzyme for performing enzymolysis on the protein and cellulose in the cordyceps militaris aqueous solution, thereby obtaining an enzymatic hydrolysate; and S3) performing filtering decolorizing treatment on the enzymatic hydrolysate so as to obtain a decolorized solution, and then sequentially performing membrane filtration, concentration and spray-draying on the decolorized solution, thereby obtaining the cordyceps militaris polypeptide. According to the preparation method provided by the invention, the polypeptide matter in the cordyceps militaris can be effectively extracted, the active polypeptide in the cordyceps militaris can be effectively utilized, and the extracting efficiency is high.

Description

technical field [0001] The invention relates to the technical field of polypeptides, in particular to a polypeptide of Cordyceps militaris and a preparation method thereof. Background technique [0002] Cordyceps militaris and Cordyceps sinensis belong to different species and are very close to the medicinal ingredients and pharmacological functions of Cordyceps sinensis. They belong to the family Ergotaceae and are recognized as fungi with high medicinal value at home and abroad. Cordyceps militaris has anti-tumor, improving immune function, anti-aging and related effects in cardiovascular and other aspects. There are many research reports on the nucleosides and polysaccharides in Cordyceps militaris, but there are few researches on its protein peptides. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a Cordyceps militaris polypeptide and a preparation method thereof for the deficiencies of the prior art.
