A study employing a chemometrics-guided lipidomics approach analyzed the degradation of four common vegetable oils—soybean, rapeseed, sunflower, and palm oil—through 40 frying cycles. This research assessed how the lipid profiles of these oils changed under repeated thermal exposure, revealing a significant reduction in triglyceride concentrations, particularly in soybean and sunflower oils. Notably, the study identified several lipid species as markers for thermal deterioration, demonstrating the potential of lipidomics for improved quality control in food production.
