Abstract:: Taking banana peel as material,base on the single factor experiment，effects of extraction conditions such as ratio of solid to solvent，ultrasonic power，extraction temperature，extraction time on the extraction effects and the optimum process were evaluated by Box-Behnken central composite experimental design and response surface methodology.The optimal extraction conditions were as follows:ratio of solid to solvent 1∶22 g/mL，ultrasonic power 80 W，extraction temperature 47℃，and extraction time 33 min.Under these conditions，the experimental values of tannin extraction yield was 87.89%,which was good agreement with the predictive value of 89.45%.It showed that optimization ultrasonic extraction process parameters for tannin from banana peel by response surface methodology were accurate and reliable.
