| 摘 要： | 以玉米胚芽油为原料，采用超临界法制备玉米共轭亚油酸(CLA)。通过正交试验方法确定最佳工艺条件为温度80℃、油:碱为1:0.5、时间4h、油:溶剂为1:2、压力15MPa，此时异构化效果理想，经气相色谱检测CLA转化率97.65%，产品中c9,t11-CLA与t10,c12-CLA含量分别为27.72%和30.88%。

| Abstract: | A series of orthogonal array design experiments were conducted for developing the optimum supercritical fluid extraction procedure of conjugated linoleic acid (CLA) from corn germ oil, which was based on 4 h extraction at 80 ℃, 15 MPa with ratios of oil to sodium hydroxide of 1:0.5 (W/W) and oil to solvent of 1:2 (W/W). Gas chromatographic analysis indicated that the CLA product obtained with a conversion ratio of 97.65% was composed of c9,t11-CLA (27.72%) and t10,c12-CLA (30.88%). |
