@@@@Enzymatic hydrolysis of sunflower oil catalyzed by lipase was investigated in a solvent-free system. Using response surface experimental design with hydrolysis temperature, pH, enzyme dosage for the trial factor, the hydrolysis rate was the response value, a mathematical model of enzymatic hydrolysis conditions were optimized. The results showed that the optimal hydrolysis conditions were:hydrolysis temperature 42℃, pH=9.8, the enzyme dosage 0.014 mg/g. Under optimal conditions, the predicted hydrolysis rate was 79.53 %, the experimental hydrolysis rate was 80.91 %. Derived from regression model fitting in good condition and meet the design requirements.
