为了获得含量较高的茶多酚,对白茶茶多酚的回流提取工艺条件进行了优化研究.以茶多酚的提取率为考察指标,以水为溶剂,通过正交试验,考查了浸提温度、时间、料液比和浸提次数对茶多酚提取率的影响.结果表明,最佳条件为:浸提次数3次,浸提温度70℃,浸提时间60min,浸提料液比1:30,按此条件,白茶茶多酚水提取率为25.58%.

In order to obtain high content of tea polyphenols, the extraction process of tea polyphenols from white tea was optimized. The effect of extraction temperature, time, ratio of material to liquid ratio and extraction times on the extraction rate of tea polyphenols was studied by orthogonal test, the extraction rate of tea polyphenols and water as solvent. The results showed that the optimum conditions were: 3 times of extraction, the extraction temperature of 70℃, the extraction time of 60min, and the ratio to 1:30, the extraction rate was 25.58%.
