Method of producing silk peptide, silk amino acid by acid hydrolysis of natural silk

A process for preparing silk peptide and serine from natural silk includes such steps as proportioning natural silk and 80-85% phosphoric acid by 1:(2-8), heating phosphoric acid to 50-120 deg.C, dissolving natural silk, reaction at 70-110 deg.C for 1-30 hr, neutralizing with lime milk, filtering to...
