| 摘 要： | 介绍以陈年绿茶为原料，用超声波法提取茶多酚，并以常温浸提做比较，分别改变提取剂的浓度、体积、酸度、提取时间及料液比对产品提取率的影响进行了探讨。结果表明超声波提取茶多酚的最佳工艺条件为：70％乙醇作浸提剂，pH值为1～2，当浸提时间40min及料液比为1：10。两次超声辐射浸提后提取率为89．29／6，该法与常规溶剂提取法相比，具有提取温度低，产品得率高，氧化损耗小等特点。

| Abstract: | Extraction technology of tea -ployphones from green tea with ultrasomic is checked and modified in the study. As a result, the optimal conditions are as follows: extraction solvent is 70% ethanol, pH is 1-2,extraction time is 40 min,ratio of solvent to material is 10:1 the stage of extraction is 2,and the extraction yield of pigment is 89. 2%. The result shows that this process has a value of high yield,low extraction temperature and less oxygenated cost. |
