[BioTech] Taiwan Researchers Develop Silk Protein Extraction Technique (
Chinese Version)
CNA - Focus Taiwan (2012/12/26) Researchers at the Council of Agriculture's Miaoli District Agricultural Improvement Station said they have developed a technique for extracting protein from silk fibers for possible use in cosmetics and the field of biomedicine.
Teng-chen WU, a researcher at the station, said silk fibers are composed mainly of protein and its base amino acid.
The inner layer of a silk fiber is made of fibroin, a natural protein, while its outer layer is sericin, a gelatinous protein that allows both layers to stick together, WU said.
Sericin can preserve and maintain moisture, is anti-oxidant, and can prevent the penetration of ultraviolet rays, WU said.
Fibroin is also UV absorbing and anti-bacterial, he said.
Both proteins extracted from silk fibers can be used to make cosmetics, health products, synthetic fibers, and biomedical materials, according to researchers.
