摘　　要：大豆油中所含游离脂肪酸(简称FFA)主要是亚油酸,亚油酸的两个双键之间含有一个活性很强的亚甲基,油脂脱色使用的脱色剂对该亚甲基参与的许多反应是天然的催化剂,本论文通过实验测定了脱色温度、时间、用量对FFA含量的影响。The main FFA included in soybean oil is linoleic acid. There is a methylene inserted between the two double bonds in the linoleic acid configuration. This methylene has very strong activity. The absorbent used in oil bleaching is a natural catalyzer for many reactions which this methylene participates in. In this study the effects of the bleaching conditions on the content of FFA were evaluated, dealing with bleaching temperature, contacting time and ratio of absorbent to oil.
