enzymes and bio-surfactants have been used for degumming of silk. Recovery of sericin from soap alkali bath has been attempted using micro, ultra and nano filtration methods. Drying has been carried out
using spray drying freeze drying or tray drying. Other methods of purification include precipitation by
ethanol for lab scale applications. The properties of sericin obtained depend upon the method used for its
extraction and recovery. During degumming process,sericin is fully/partially hydrolyzed, and solubilized in degumming medium. Therefore, there is a need to develop extraction processes for sericin that are energy efficient, produce no chemical discharge and cause minimum damage to sericin.
