Preparation method of yak skin gelatin for promoting platelet activation

Abstract

The invention relates to a preparation method of yak skin gelatin for promoting platelet activation. The method comprises the following steps: (1) cleaning fresh Tibetan plateau yak skin with hair, and performing irradiation with ultraviolet lamps to obtain irradiated yak skin; (2) cutting the irradiated yak skin into blocks of 1-3cm, performing extraction in boiling water, taking out the yak skin, and piercing the yak skin with a spiny plate; (3) putting the yak skin obtained in the step (2) into an enzymolysis solution with the mass concentration of 0.5-8% for enzymolysis, and performing filtration to obtain filtrate; (4) adding active carbon into the filtrate, performing full stirring, performing boiling and filtration to obtain a first enzymolysis solution and filter residue respectively; (5) putting the filter residue into an enzymolysis solution with the mass concentration of 1-10% for enzymolysis so as to obtain a second enzymolysis solution; (6) combining the first enzymolysissolution and the second enzymolysis solution, performing boiling for 5 to 40 minutes, and performing centrifugal separation to obtain supernatant; and (7) ultra-filtering the supernatant with a hollowfiber membrane to obtain a yak skin collagen solution, and freeze-drying the yak skin collagen solution to obtain the yak skin gelatin. The method of the invention is simple and easy to implement.

Description

technical field

[0001] The invention relates to a preparation process of collagen, in particular to a preparation method of yak skin glue which promotes platelet activation. Background technique

[0002] At present, the research on yak skin has been carried out with collagen after depilation, ignoring the effect of yak hair. Cow hair is mainly composed of keratin, which has a long chain of amino acids. Keratin is similar to collagen. There are two main proteins, one is intercellular protein with more sulfur elements, which contains cystine; the other is sulfur-containing Less fibrin.

[0003] Cystine is a sulfur-containing amino acid, which is mostly contained in keratin. It is one of the essential amino acids for the human body and has no adverse effects on the human body. In medicine, it can promote the oxidation and reduction function of body cells, increase white blood cells and prevent the development of pathogenic bacteria. It is also used for dysentery, typhoid, inf...
