Optimization of Microwave-assisted Extraction of Tannic Acid from Chinese Gallnut Using Response Surface Method
摘要
Abstract
The microwave-assisted extraction process of tannic acid from Chinese gallnut were optimized using response surface method (RSM). The effects of three independent variables, i. e. liquid to solid ratio, microwave extraction time and extraction temperature, on the yield of tannic acid, was also investigated. Results indicated that the optimum microwave-assisted extraction was obtained as the powder of Chinese gallnut 10 g, microwave power 600 W, liquid to solid ratio 32 ∶ 1 ( mL∶ g) , ultrasonic extraction time 7 min and temperature 62℃, respectively. Under this optimum condition, the extraction yield of tannic acid was 65.13%.关键词
