| titleOfInvention | A kind of silk element oligopeptide preparation method for skin care item |
| abstract | The invention discloses a kind of silk element oligopeptide preparation methods for skin care item, comprising the following steps: (1) degumming: by silk cocoon 0.5-0.8%Na 2 CO 3 Dipping, washing and drying；(2) salt solution: 50-60%CaCl is used 2 , dissolve in boiling water, be centrifuged after cooling, supernatant dialysis obtains small molecule silk fibroin protein solution；(3) double enzymolysis: double enzymolysis processing, centrifugation are carried out with alkali protease and actionozyme, supernatant dialysis obtains low molecular weight silkworm silk fibroin solution；(4) UF membrane: being separated with sephadex chromatography column Sephadex G-15, collects component, obtains silk element oligopeptide solution；(5) fibroin oligopeptide solution kept dry: is subjected to cryogenic temperature freezing drying up to the oligomeric Gly-His-Lys of silk element.Silk element oligopeptide preparation method of the invention is easy to operate, 93% or more recovery rate, the adding raw materials suitable for skin care item and cosmetics. |
