利用生石灰水沉淀法提取都匀毛尖加工废弃物中茶多酚工艺研究

The Use of Lime Extraction Technology of Tuyun Maojian Tea Polyphenols in Processing Waste Water Precipitation

采用生石灰水沉淀法与四因素三水平的正交实验方案对都匀毛尖加工废弃物中茶多酚提取工艺条件进行了研究,找到最佳的工艺参数以指导生产实践。结果表明,当茶末筛取筛网大小为10目,在热水浸提温度为90℃,时间为30min,搅拌强度80r/min时,茶多酚的实际提取率为2.25%左右。

By orthogonal experimental scheme of lime water precipitation method with four factors and three levels of Tuyun Maojian tea processing waste tea polyphenols extraction process conditions were studied to find the optimal process parameters to guide the production practice. The results show that when the tea picking up the screen size is 10 mesh, in the hot water extraction temperature is 90℃, the time for 30min, stirring intensity 80r/min, the actual extraction rate of tea polyphenols was about 2.25%.
