Product
a colloidal protein coated on the outer layer of silk silk. Off-white or light yellow powder, easily soluble in water, positive for ninhydrin reaction.
Total nitrogen (%): ≥14.
PH value: 5.0-7.0
Polar side amino acids accounted for total amino acids (%):> 70 or more
Application: Serine and aspartic acid are very high in polar side groups. It is a protein with extremely rich hydrophilic groups. Among them, amino acids with hydrophilic polarity reach about 75%, and the content of serine is 30%. Its hygroscopicity is 50 times stronger than that of glycerol. Therefore, it has very good hygroscopicity, moisture retention, breathability and antimicrobial properties as a raw material for cosmetics and chemical fiber coatings . And its film-forming property is also very good, its film is shiny, hair feels good, and elastic. At the same time, sericin has excellent oxidation resistance. It can effectively inhibit the activity of polyphenol oxidase in food, is an excellent natural antioxidant for fat foods, and has very significant value for the development of additives that extend the shelf life of dairy foods. Using sericin as the main raw material and cross-linking with a cross-linking agent, coating on products such as chemical fiber, underwear, bedding, skin-friendly products, leather, etc., can achieve silky effects such as skin care, skin-friendly, antibacterial and comfort.
