正己烷-无水乙醇体系萃取茶叶籽浆液工艺研究

Study on extraction technology of tea seed slurry by hexane-ethanol system

改变了传统的提取工艺,利用正己烷-无水乙醇体系对茶叶籽浆液进行萃取,静置分层后得到茶油、茶皂素及蛋白。在单因素试验的基础上设计正交试验,得出了最优工艺条件为茶叶籽浸泡24 h、混合液质量比(正己烷∶无水乙醇∶浆液)1∶1∶1、萃取温度30℃,振荡萃取时间0.5 min和萃取2次。

The traditional extraction technology was changed and tea seed slurry was extracted by hexane-ethanol system to get tea, tea saponin and protein. On the basis of single factor experiment, the process conditions were optimzed by orthogonal experiments as follows： tea seed soaking 24 h, mass ratio of mixed liquor （hexane ： ethanol ： slurry） 1 ： 1 ： 1, extraction temperature 30℃, oscillating extraction time 0.5 min, and extracting 2 times.
