초록
Sericin undergoes gelation by the structural transition from random coil to b-sheet transition. In the present study, the gelation time of sericin solution was investigated in the presence ofNaCl, KCl and CaCl2. The addition of salts delayed the gelation time, and CaCl2 had the mostpronounced effect, which delayed about 8 h at maximum. The gelation time increased withthe concentration of salt. The transition of secondary structure of sericin was retarded in thepresence of salt. The effect of salts on the gelation time of sericin might be due to the solvationeffect of relevant cation
