| Abstract: |
| 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. |
