Unsaturated fatty acids are easily affected by metal ions, leading to the changes of their flavor, nutrition, and safety through lipid oxidation. Nevertheless, there is a lack of comprehensive evaluation of the pro-oxidative ability of different metal ions, which have different effects on different lipids. Thus, in this work, crude lipids extracted from abalone were incubated with different metal ions, and the comprehensive lipid oxidation products were analyzed by nontargeted lipidomics approaches using an ultra-high-performance liquid chromatography-Q-Exactive HF-X Orbitrap Mass Spectrometer (UPLC-Q-Exactive HF-X). Results showed that the overall pro-oxidative ability from strong to weak was Fe |
