| 摘 要： | 采用单因素和正交试验法讨论超临界CO2 萃取牡丹籽油过程中萃取温度、压力、时间及CO2 的流量因素对牡丹籽油脂的萃取率及不饱和萃取液中脂肪酸的含量的影响。并采用GC-MS 技术对油脂成分进行分析。结果表明，采用超临界CO2 流体技术可以萃取牡丹籽中的油脂成分，其最佳工艺条件为压力30MPa、萃取温度40℃、萃取时间2.5h、二氧化碳流量25kg/h。此时油脂的萃取率为30.7%，萃取液中不饱和脂肪酸的相对含量可达70.81%。

| Abstract: | Single factor and orthogonal array design method were used to optimize the extraction of peony seed oil using supercritical carbon dioxide (SC-CO2) with respect to the effects of extraction pressure and temperature, length of extraction. Along with this, the chemical composition of the extracted peony seed oil was analyzed by GC-MS. The results showed that the optimized SC-CO2 extraction for 2.5 h at 40 ℃, 30 MPa and a CO2 flow rate of 25 kg/h resulted in a maximum oil yield of 30.7%. The total content of unsaturated fatty acids of the extracted peony seed oil was 70.81%. |
