Embodiment 1

[0047] This embodiment provides a method for preparing biologically active peptides from snail protein, which specifically includes the following steps:

[0048] S1. Processing of snails: wash the snails, remove the shells, and separate the viscera and snail meat;

[0049] S2. Preparation of helicase: add phosphate buffer solution with a pH value of 5.5 to the viscera obtained in step S1, the mass volume ratio of the viscera to buffer is 1:3g / mL, pulverize with a meat grinder, and centrifuge at 3000r / min for 15min , taking the supernatant, using an ultrafiltration membrane with a pore size of 1000D to concentrate to a relative water density of 2, and freeze-drying to obtain helicase;

[0050] S3. Preparation of minced snail meat: crushing the snail meat with a meat grinder to obtain minced snail meat;

[0051] S4. Snail enzyme enzymolysis: Add 75 parts by weight of water and 2 parts by weight of helicase obtained in step S2 to 50 parts by weight of the minced snail meat obtai...

Description

technical field [0001] The invention relates to the technical field of active peptides, in particular to a bioactive peptide prepared from snails and its preparation method and application. Background technique [0002] Snails belong to gastropod terrestrial molluscs, which have high edible and medicinal value. The species commonly bred in China is the white jade snail, whose mucus mainly contains active ingredients such as collagen, allantoin, chondroitin sulfate, vitamins, and natural antimicrobial peptides. Among them, allantoin can regenerate the skin; protein and vitamins can increase the nutrition of the skin, making the skin more delicate and smooth. At present, most of the application and development of snail products are concentrated in the fields of food and cosmetics, and the research on it is mainly the extraction of polysaccharides, helicase, and secretions, but there is no research report on the extraction of cosmetic-grade snail mucus. [0003] "Comparative ...
