摘　　要：为了提高玉米胚芽油的提取率,采用冷冻-微波解冻和乙醇冷浴辅助水酶法提取玉米胚芽油,通过正交实验优化冷冻-微波解冻预处理条件和乙醇冷浴预处理条件。实验结果表明:优化冷冻-微波解冻预处理条件,包括冷冻温度、冷冻时间、粉碎时间和微波解冻时间,得出玉米胚芽油提取率为69.22%;优化乙醇冷浴预处理条件,包括冷浴时间、冷浴温度、乙醇质量分数和m(玉米胚芽)∶V(乙醇),得出玉米胚芽油提取率为58.27%。To enhance the extraction yield of corn germ oil,the oil was produced using freeze-microwave thawing and ethanol cold bath assisted enzymatic extraction.The conditions of freeze-microwave thawing pretreatment and ethanol cold bath pretreatments were improved by orthogonal experiment.The experimental results showed that the corn germ oil yield was 69.22%by optimizing the freeze-microwave thawing pretreatment conditions,including freezing temperature,freezing time,crushing time,and microwave thawing time.The corn germ oil yield was 58.27%by optimizing ethanol cold bath pretreatment conditions,including cold bath time,cold bath temperature,ethanol mass fraction,and m(corn germ)∶V(ethanol).
