| Abstract;Conditions for preparing water-soluble sericin as a food material was examined and the general components of the sericin obtained and its in vitro and in vivo digestibility was studied. A general composition analysis of water-soluble sericin that was prepared by heat extraction of home-use silk thread with a 0.05% sodium carbonate solution followed by dialysis and freeze-drying showed that 90% of it was proteins and Ser, Asp, and Gly made up about 50% of the amino acid content. In addition, the rates of artificial digestion of the water-soluble sericin were at 33%, 29%, and 34% with pepsine, trypsin, and chymotrypsin, respectively, which were lower than 87.2%, or that of casein. The true ratio of in vivo digestion of the water-soluble sericin in rat was 45%. |
