Silk Fibroin

The resource and characteristics of silk fibroin:With the adoption of modern bio-technology, silk essence, unglued from silk, derives from the hydrolyzation of fibroin protein, which creates polypeptide and amino acid. Multiple amino acid and dipeptide, tripeptide are extracted from natural silk. With abundance of 18 kinds of amino acid, namely, glycin, alanine, alpha-amino-beta-hydroxyrpropionic acid, beta-parahydroxy-phenylpropionic acid (up to 80%), silk fibroin is white crystallized soluble powder and is prone to be absorbed by human beings. So silk fibroin is added to the cosmetics. Regarding the unique feature of reactive peptide, silk essence, varying from ordinary blended amino acid, has bright prospect in food and cosmetic industry. The quality index of silk essence:External appearance: white or light yellow powder with proper smell
