Abstract: The effects of reaction temperature, pH, enzyme concentration and ch itosan concentration on the hydrolysis of chitosans by papain were studied. It showed that the optimum temperature and pH were 50℃ and pH4.5 respectively. Th e reaction velocity was increased while the enzyme concentration raised. Finall y , the kinetic equation was established.

Key words: chitosan, papain, depolymerization, kinetics
