Taiwan Researchers Develop Silk Protein Extraction Technique

Source: Taiwantrade | Updated: 08 February 2013

Wu Teng-chen, 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.
