| 摘 要： | 菜籽油的物理精炼,是借助蒸汽的汽提作用除去油内的游离脂肪酸及其他有气味的物质和易挥发的杂质,精炼中不产生皂脚和处理皂脚带来的污染问题,且中性油损失较少,因此,这是一种有前途的植物油脂精炼新工艺。本文主要讨论菜籽油物理精炼的物理化学原理。

| Abstract: | The physical refining of edible oils has aroused people's interest, for in comparison with the chemical refining, it can remove all the free fatty acid as well as the odorant and volatile impurities by steam strip- ping. In refining process there will be no soap stock, and so no pol- lution problem caused by waste treatment. And the proess can reduce neutral oil loss to a minimum. Our study of the physical refining of rapeseed oil is made on a laboratory scale. This paper deals with the physical and chemical fundamentals of physical refining of rapeseed oil. |
