不同方法提取茶多酚的比较研究

A comparison study on extracting tea polyphenols by different technique

以新鲜茶叶为材料,比较研究了茶多酚超声波提取和传统有机溶剂提取两种工艺及其对茶多酚提取率和品质的影响。实验结果表明,同等条件下,超声波法具有省时、成本低、操作简便、提取率高、氧化损耗小、产品纯度高等优点,提高了产品的品质和收率,提取的效果优于传统有机溶剂法。

Using fresh tea as material,extracting the polyphenols by ultrasonic wave auxiliary method and the traditional organic solvent extraction method was comparison studied in this paper,the different effect on the extraction rate and quality was also studied too.The conclusion shows:the ultrasonic wave auxiliary method was better than the traditional organic solvent extraction method at the same condition,and have many advantages,for example the time-saving,the high efficiency,the low cost,the easy to operate,the improving product quality etc.
