| Abstract: |
| An analytical method for the rapid analysis of edible vegetable oils was developed by ambient flame ionization mass spectrometry(AFI-MS).The AFI-MS was used to analyze four edible vegetable oils,including olive oil,sesame oil，peanut oil and sunflower oil.26 kinds of triglycerides and 11 kinds of dialycerides in olive oil,peanut oil,sunflower oil,sesame oil were detected by the AFI-MS.In view of the differences of MS profiles of edible vegetable oils(olive oil,sesame oil，peanut oil and sunflower oil),the relative abundances of triglycerides in edible vegetable oils were obtained.The differences of relative abundances were capable of preliminary identification of four edible vegetable oils.The experimental results demonstrated the feasibility and convenience for fast analysis of edible vegetable oils by the AFI-MS.The results showed that the simple and convenient AFI-method is potential for fast analysis of edible vegetable oils. |
