甲醇-6号溶剂-水混合溶剂浸提油茶籽油的研究

Extraction of oil-tea seed oil by methanol-hexane-water

考察了混合溶剂(Methanol-H2O-Hexane)浸提油茶籽油的浸出工艺,得出最佳操作条件为:粉碎脱壳油茶籽至颗粒过40目筛子为宜,浸提时间15 min,浸提温度为50℃,6号溶剂与料比为4(V/W),甲醇溶料比4,水料比为0.4时,油茶籽油得率为84.97%,茶皂素得率为86.79%;在得到粗油茶籽油的同时,也得到纯度较高的茶皂素,从而为油茶籽资源的开发提供了一种新的工艺。

Process of oil-tea seed oil extraction by methanol-hexane-water mixture was studied, the best operation condition was： the particle passing through 40-mesh sieve, of extraction time 15 min, ratio of hexane to stuff 4：1（ V/ W）, ratio of methanol to stuff 4： 1 （ V/ W）, ratio of water to stuff 0.4 ： 1 （ V/W）, extraction temperature 50℃ o Crude tea oil and tea saponin were gained by one step extraction with methanol-hexane-water mixture.
