SILK SOLUBILIZATION METHOD FOR PRODUCING SILK PEPTIDE FOR IMPROVING MEMORY AND COGNITIVE FUNCTION AND METHOD FOR PRODUCING HYDROLYZATE THEREOF

摘要

The present invention relates to a method for dissolving silk and a method for producing a hydrolyzate thereof. Silk fibroin solubilization method according to the present invention is a sericin removal step of mixing the cocoon and purified water and heat treatment to remove sericin and obtain silk fibroin; Solubilizing the silk fibroin in a mixed solution containing sodium chloride; And removing the mixed solution from the lysate. In the case of the present invention, silk fibroin can be solubilized without using high-purity calcium chloride, which is generally used for solubilization of silk fibroin. Therefore, it can be used to use silk fibroin for various purposes.
