| Abstract: |
| In order to explore safe and efficient methods for vegetable oil analysis as well as provide theoretical references for vegetable oil adulteration, two main analytical methods of oil omics and their applications in vegetable oil adulteration were reviewed. Oil omics is an important method and tool for the analysis of vegetable oil composition, identification of marker metabolites, and judgment of vegetable oil adulteration, and its determination methods mainly include chromatography-mass spectrometry(liquid chromatography-mass spectrometry, gas chromatography-mass spectrometry, supercritical fluid chromatography-mass spectrometry, multidimensional chromatography-mass spectrometry) and shotgun lipidomics. Oil omics is an accurate and reliable method to identify adulterated vegetable oils, which is of great significance to ensure the safety of vegetable oil consumption. The combination of oil omics and chemometric methods (principal component analysis, linear discriminant score, partial least squares, etc.) to extract effective information for modeling from a large amount of complex data is one of the most promising directions for identifying adulterated vegetable oils in the future. |
