摘　　要：对正戊烷和正己烷浸出的大豆毛油及大豆粕的质量进行比较,论述了正戊烷浸出的优点。研究结果表明,正戊烷的浸出率比正己烷略高,浸出所得的大豆油色泽浅;正戊烷浸出大豆粕脱溶温度低,蛋白溶解度高,加工过程能耗低。正戊烷是一种优良的浸出溶剂。The quality of the crude oil and meal of soybean extracted with n - pentane were compared with that extracted by n - hexane. The result showed that the extraction with n - pentane had more merits than that with n -hexane, such as higher oil yield,light color oil with better quality, lower desolventizing temperature of meal, higher solubility of protein in the meal, and lower cost in the process. The n - pentane is one of good extraction solvents.
