Raw silk consists of silk gum and silk pigment, in which the presence of silk gum and other impurities will carry a certain immunogenicity, affecting the application of silk pigment proteins in biologically related fields. Degummed silk refers to the preparation of silk fibroin containing only sericin proteins after treatment to remove silk glue and its impurities.</span></span></p>
