| 中文摘要: |
| 以新疆石榴籽为原料，超声辅助溶剂法提取石榴籽油，在单因素试验的基础上，通过正交试验确定了超声辅助溶剂法提取石榴籽油的最佳工艺条件。结果表明，石榴籽油的最佳提取工艺条件为：石油醚（60~90℃)为提取溶剂，石榴籽粉碎粒度60目，料液比1∶10，超声功率240 W，超声处理时间50 min，超声处理温度45℃；在该条件下，石榴籽提油率为15.09％。GC-MS分析结果显示，石榴籽油的主要脂肪酸为：棕榈酸6.24％、亚油酸14.64％、油酸11.11％、硬脂酸3.97%、石榴酸43.46％、9，12，15-十八碳三烯酸11.31％、6，9，12-十八碳三烯酸9.28％。 |
| 英文摘要: |
| With Xinjiang pomegranate seed as raw material，pomegranate seed oil was extracted by ultrasound-assisted solvent method. On the basis of single factor experiment，the extraction conditions were optimized by orthogonal experiment. The results showed that the optimal extraction conditions were obtained as follows：with petroleum ether (60-90℃) as extraction solvent, particle size of pomegranate seed powder 60 meshes, solid-liquid ratio 1∶10，ultrasonic power 240 W，ultrasonic treatment time 50 min and ultrasonic treatment temperature 45℃. Under these conditions，the yield of pomegranate seed oil was 15.09％. The analysis results of GC-MS indicated that the main fatty acids of pomegranate seed oil were as follows：palmitic acid 6.24%，linoleic acid 14.64%，oleic acid 11.11%，stearic acid 3.97%，punicic acid 43.46%，9，12，15-octadecatrienoic acid 11.31% and 6，9，12-octadecatrienoic acid 9.28%. |
