摘　　要：采用水酶法提取玉米胚芽油,对其预处理参数进行优化。预处理的最佳工艺条件为玉米胚芽粉碎粒度250μm,蒸汽处理温度108℃,时间45min,浸泡液pH3.4。在此工艺参数下,清油提取率达到71.95%。The extraction of corn germ oil by aqueous enzymatic method was adopted. The conditions of pre- treatment were optimized. The optimal parameters of pre-treatment were size of corn germ 250 μm, at 108 ℃ atmospheric bathing for 45 min, and pH of buffer 3.4. Under optimal conditions, the yield of free oil reached 71.95 %.
