Among lipid classes, glycerolipids (GLs),particularly triacylglycerols (TAGs), are the most frequently analysed in food-related studies.Results: Matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) and MALDI mass spec-trometry imaging (MSI) have emerged as powerful tools for lipidomic investigations. While traditionally appliedin biological research, their use in food science is expanding to diverse matrices, including oils, dairy, cereals,algae, and meat. In terms of MALDI matrices, 2,5-dihydroxybenzoic acid (DHB) is most commonly used inpositive ion mode, whereas 9-aminoacridine (9-AA) is typically employed in negative mode. MALDI-MS hasadvanced lipid characterization, and MALDI-MSI now enables mapping of lipid spatial distributions, revealingprocesses such as lipid degradation.Significance: This review underscores the growing utility of MALDI-MS and MALDI-MSI for lipid analysis in foodscience. We highlight their analytical capabilities, workflows, and limitations, it demonstrates how these tech-niques can enhance understanding of food composition, quality, and authenticity.
