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。结果表明 ,传统的常规碱炼技术可以对酸值在 2 0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。实验室试验表明稀溶液分步间歇式碱炼的工艺流程 ,可以在低炼耗的水平上得到酸值较理想的花椒籽碱炼油 ,同时该碱炼方法也能显著的降低花椒籽油的色度。
The article studied on the practical technology of alkali refining high acidity pricklyash seed oil to deacid on the base of previous research.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.The experiment indicated that the technology process can acquire pricklyash seed oil whose acidity is appropriate at the level of losing,meanwhile the method can notably decrease chroma of the pricklyash seed oil.
