METHOD FOR MANUFACTURING SILK PEPTIDE

摘要

Method for manufacturing silk peptide is disclosed. The method according to the present prepares 40 ~ 60% of CaC12 solution using food grade CaC12 and purified water. And then solubilizes cocoon by inputting the cocoon into the CaC12 solution, and dilutes the CaC12 solution by inputting 150±10% of purified water with respect to the solution by weight ratio into the solubilized solution, filtering, desalinating, and sterilizing the diluted solution. And then adjusts the pH using food grade acetic acid or sodium acetate, inputting protease-N solubilized with pufifying water into the solution, and hydrolizing it a certain time. According to the present invention, it is able to reduce possibility of fire and/or water polution might be happened in case of the conventional silk peptide manufacturing method using ethanol in solubilization step, and also manufacturing cost could be reduced.
