摘要
研究了梨皮中多酚的提取工艺,通过正交实验确定了最佳提取条件。结果表明:梨皮中多酚的最佳提取工艺条件为温度70℃,固液比1∶11(w/v),乙醇浓度60%,浸提时间60min。该条件下的多酚提取率为0·5mg/g。
The extraction technology of polyphenols in pear peel was studied and the optimal conditions of the extraction were determined by orthogonal test. The results indicated： the optimal conditions of extraction of polyphenols in pear peel were 70℃,the ratio of solid to liquid 1：11 （w/v）,60% ethanol concentrations and 60min extracting times,the extracting rate of polyphenols was 0.5mg/g.
