马铃薯皮中绿原酸提取工艺研究

Optimization of chlorogenic acid in the potato peel the best extraction process.The content of chlorogenic acid was determined by an ultraviolet visible spectrophotometric method.The ultrasonic-assisted extraction of chlorogenic acid in potato peel was optimized by a single factor test and an orthogonal experiment. Results show that Chlorogenic acid extraction rate was 3.85% in the potato skinthat,the optimal extraction conditions were: ultrasonic irradiation time 50 min,volume fraction of ethanol 60%,ultrasonic power 80W,liquid and material ratio 1:15. from which to extract chlorogenic acid, abundant raw material sources, extraction process is simple, high efficiency.
