| 中文摘要: |
| 以栀子渣为原料，利用二次回归正交实验对栀子渣油超临界CO2O萃取工艺条件进行优化，利用正交实验对有机溶剂萃取工艺条件进行优化。初步确定超临界CO2萃取法的最优工艺参数为：萃取压力40 MPa、萃取温度55℃、CO2O流速15 kg/h；有机溶剂萃取法的最优工艺参数为：萃取温度50℃、料液比1∶4.5、萃取时间240 min、原料水分含量4.0%。对两种制取方法在最优工艺条件下所得栀子渣油的品质比较可知，制取高品质的栀子渣油宜采用超临界CO2萃取法。 |
| 英文摘要: |
| The oil were extracted from gardenia pomace by supercritical CO2 extraction and organic solvent extraction methods, and the extraction conditions of supercritical CO2 extraction were optimized by quadratic regression orthogonal experiment, and the extraction conditions of organic solvent
extraction were optimized by orthogonal experiment. The optimal extraction conditions of supercritical CO2 extraction were intially determined as follows：extraction pressure 40 MPa, extraction temperature 55℃, velocity of CO2 15 kg/h. The optimal extraction conditions of organic solvent extraction were determined as follows：extraction temperature 50℃, ratio of solid to liquid 1∶4.5, extraction time 240 min, moisture content of raw material 4.0%. The comparison in quality of gardenia pomace oils extracted by these two methods under the optimal conditions showed that supercritical CO2 extraction was suitable for extracting gardenia pomace oil with high quality. |
