Therefore, to ensure the purity of fibroin, the silkworm cocoons need to be pretreated. Since sericin protein is rich in amino acids and has good water solubility, in the process of fibroin extraction, it is usually separated from fibroin fibers by the method of high-temperature water-soluble degumming. The existing extraction process is mainly: degumming, drying, silk reeling, dissolving, dialysis, freeze-drying. The current preparation process is to place the silkworm cocoons in a boiling salt solution for 20 - 90 minutes, stir with a stirring rod during the process, repeat multiple times, then rinse with clean water, manually squeeze out the water, and put it into an oven for drying for the next operation;
