| 摘要: |
| 采用微波辐照诱导萃取南瓜子油,并利用GC-MS对其脂肪酸进行化学成分分析和鉴定。结果得到,用微波辐照诱导萃取南瓜子油的最佳工艺条件是在微波功率900W下,用正已烷提取50s,南瓜子油得率为41%。南瓜子油中亚油酸含量高达56.54%,不饱和脂肪酸含量达到65.43%,是制备营养保健油的优质原料。微波提取的南瓜子油颜色澄清、香味自然,与其他提取方法相比,具有提取时间短、得率高等优点。 |

| Abstract: |
| Pumpkin seed oil was extracted by the microwave method and the chemical components of fatty acids were analyzed by GC-MS.The results show that when pumpkin seeds were extracted at 900W with n-hexane for 50s, the obtained rate of pumpkin seeds oil is 41%.The relative contents of Linoleic acid from pumpkin seeds oil was up to 56.54% and the unsaturated fatty acids were 65.43%, they were the high quality material to make nutrimental and sanitarian oil.Pumpkin seeds oil extracted by microwave method is quite clear and fragrant.The microwave method has more advantages than the other extracting methods on shorter extracting time, higher obtained rate etc. |
