Optimization of Ultrasonic-assisted Extraction of Tannic Acid from Chinese Gallnut Using Response Surface Method
摘要
Abstract
The ultrasonic-assisted extraction of tannic acid from Chinese gallnut with water as extraction agent were determined on the basis of single factor experiment using response surface method ( RSM ). According to central composite ( Box-Behnken ) design principle, the effect of three independent variables on the Yield of tannic acid, namely liquid to solid ratio, ultrasonic extraction time, and ultrasonic power was investigated. The results showed the optimum ultrasonic-assisted extraction conditions were: 5 g of Chinese gallnut powder, liquid to solid ratio 38 : 1 ( mL: g), ultrasonic extraction time 32 min, ultrasonic power 250 W. Under the optimum conditions, the extraction yield of tannic acid was 66.0 %.关键词
