Furan fatty acids (FuFAs) have been recognized as beneficial food ingredients to human health. Herein, a targeted quantitation approach by gas chromatography coupled to triple quadrupole tandem mass spectrometry (GC-TQ/MS) was developed for the identification of FuFAs in common marine and other edible oils in multiple reaction monitoring (MRM) mode without any isolation and enrichment. The limit-of-quantitation (LOQ, 0.6 pg) was determined under the optimized parameters in MRM mode. Identification of FuFAs in common edible oils demonstrated that marine fish oils were concentrated sources of 9-(3-methyl-5-pentylfuran-2-yl)nonanoic acid (9M5), 11-(3,4-dimethyl-5-propylfuran-2-yl)undecanoic acid (11D3) and 11-(3,4-dimethyl-5-pentylfuran-2-yl)undecanoic acid (11D5). However, FuFAs were not identified in common plant oils. Additionally, 11D5 was identified in the lipids of Schizochytrium limacinum at a comparable level with that in marine fish oil. We believe that this protocol could facilitate the qualitative and quantitative analysis of FuFAs in food and biological samples.
