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.
