摘  要:
以香蕉皮为试材,在单因素试验的基础上,运用Box-Behnken法和响应面法考察了料液比、超声功率、提取温度和提取时间4个因素对香蕉皮中单宁提取率的影响,并优化了提取工艺。结果表明:最佳提取工艺条件为料液比1∶22g/mL、超声功率80W,提取温度47℃,提取时间33min,在此条件下,单宁提取率的预测值为89.45%,验证试验值为87.89%。

摘  要:
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∶22g/mL,ultrasonic power 80 W,extraction temperature 47℃,and extraction time 33min.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.
