Study on microwave acid hydrolysis of the corm powder of banana root

In order to research the convenient and efficient saccharification method of the banana root corm powder, this study applied microwave heating method in acid hydrolysis the corm powder of banana root.The influence of acid concentration, liquid-solid ratio, microwave power and time on the hydrolysis rate were studied, and response surface analytical method was used to optimize its reducing sugar yield.Using DesignExpert software, the result was fitted in multiple regression and analyzed, when the hydrochloric acid concentration 0.3mol/L, liquid-solid ratio 23mL/g, microwave time 20min, microwave power 600W, the reducing sugar yield of the banana root corm powder was 48.95 percent, which was in line with forecast.
