Abstract
Antheraea pernyi silk fibroin (SF) hydrolysate were characterized using UV–VIS spectrometer, amino acid composition and heavy metal contents to explore its potential sources for food or cosmetic additives. The hydrolyzed A. pernyi SF was separated into two parts: (a) SFA, alanine-rich fraction and (b) SFB, tyrosine-rich fraction. SFB exhibited strong absorption peaks at 210 and 280 nm due to the presence of the tyrosine. Heavy metal analysis showed that arsenic and mercury did not detect. Other heavy metals, which includes lead, cadmium, etc., were recorded only a trace amount. Therefore, A. pernyi SF hydrolysate could be safely used as sources of food, cosmetic and pharmaceuticals.
