摘　　要：以淀粉加工副产物玉米胚为原料,经过超临界CO2流体萃取脱脂处理后,再经过破壁而使还原型谷胱甘肽充分溶出。根据实验室条件及试验要求,本试验采用冻溶、微波及超声波破3种方法进行对比破壁,以GSH溶出量为考核指标,确定最佳细胞破壁方法为超声波破碎,并且确定超声波破碎工艺条件为:工作时间5s;间隔5s;超声次数30次;温度常温;输出功率为400W。With corn embryo being coproduct in corn starch production as material,the glutathione （GSH）was extracted by breaking the cytoderm after supercritical CO2 fluid extraction.According to the laboratory conditions and test requirements,three methods with cold solvent,microwave and ultrasonic was compared to the amount of assessment indicators for GSH dissolved.The results showed that the best method in breaking the cytoderm is ultrasound wave treatment and the best conditions is：time 5 s;interval 5 s;times 30;power 400 W.
