The article studied on the practical technology of alkali refining high - acidity pricklyash seed oil to deacid on the base of previous research
摘要在前人研究的基础上，对高酸值花椒籽油的碱炼除酸实用技术进行了进一步的研究。
The result indicated that traditional technology of normal alkali refining can refine the pricklyash seed oil whose acidity under 20 , but the method of by stage alkali - refining using dilute - solution can process pricklyash seed oil whose acidity above 60 ~ 70
结果表明，传统的常规碱炼技术可以对酸值在20以下的花椒籽油进行精炼；而采用稀溶液分步间歇式碱炼则可以处理酸值高达60 ~ 70的花椒籽油。
