摘　　要： 植物粗油中含有磷脂、蛋白质、悬浮物等胶体杂质，造成浑浊，影响油的品质．因而食用植物油一般都需经水化脱胶等精炼处理．本文研究了应用磁场处理技术对植物油的水化除磷脂过程的强化作用．结果表明：经适当的磁处理可使大豆油中残留的磷脂量降至未经磁处理的对照样的１／１４；大豆油和花生油的粘度降低了１％～２％；水的表面张力降低了近１／１０；花生油的澄清沉降速度也能提高一半以上．最后初步探讨了磁场的作用机理． There exist many impurities in crude vegetable oil, such as phospholipid, protein and suspension, which may affect the quality of oil, and cause turbidness. Therefore, the edible vegetable oil has to be refined for de-gum by hydration. This research works at the application of magnetic treatment for strengthening the removal of phospholipid with the removal of ration of vegetable oil. It was found that by using a suitable magnetic treatment, the remnants of phospholipid in soybean oil can be reduced to 1 /14 of the control sample; a 1% -2% reduction in viscosity for soybean oil can be made; the surface tension of water can be dropped to about 90% and the settling rate of crude peanut oil can be raised by more than 50%. Finally, the mechanism of magnetic treatment was briefly discussed.
