| 中文摘要: |
| 采用气相色谱-质谱联用技术对花生油及花生油香精中挥发性成分进行分析,剔除共有成分后，对所获得数据采用SPSS统计软件进行分析，将花生油香精中69个特征挥发性成分分为两类。通过对掺伪不同比例花生油香精的花生油样品分析，归为第一类的14种特征物质能很好地区分掺伪花生油香精，其检出限低至0.01%（占花生油体积分数），可为鉴别花生油掺伪花生油香精和评价花生油的品质提供技术参考。 |
| 英文摘要: |
| The volatile components in peanut oil and peanut oil essence were detected by GC-MS. After taking out the same components in peanut oil and peanut oil essence, 69 kinds of characteristic volatile compounds in peanut oil essence were divided into two categories through SPSS analysis. Peanut oils adulterated with different ratios of peanut oil essence were analyzed. The results demonstrated that peanut oil adulterated with peanut oil essence could be distinguished well by the 14 kinds of characteristic compounds in the first category, and the limit of detection was as low as 0.01%(based on volume of peanut oil). The established method could provide technical reference for the identification of peanut oil adulterated with peanut oil essence and evaluation of the quality of peanut oil. |
