Content and type of triacylglycerols (TAGs) in edible oils are closely related with our health, it is of significance to develop a fast and high-efficiency method for the determination of TAGs. In this manuscript, a fast and direct method for qualitative analysis of TAGs was established using matrix-assisted laser desorption/ionization Fourier transform ion cyclotron resonance mass spectrometry (MALDI-FTICR-MS). 2,5-DHB was employed as matrix and dichloromethanewas used as solvent for dissolving edible oils. With laser power of 15%, laser frequency of 100 Hz and 100 laser shots, repeatability was evaluated using relative standard deviation (RSD) and less than 10% was obtained. Different kinds of edible oils could be directly distinguished from each other using MS and MS/MS results.With confidence level of 95%, principal component analysis (PCA) results show that 34 different kinds of edible oils were clearly classified. Using this method 5% doped canola in olive was identified directly,indicating that MALDI-FTICR-MS has the potential for rapid analyzing and screening edible oils.
