A very simple, fast, and non-destructive approach to predict the time at which edible oils submitted to high temperature reach the established limits of safety

► The original percentage in weight of polar compounds %PC0 depends on oil composition. ► Time to reach 25% in weight of polar compounds T25%pc depends on the oil composition. ► %PC0 and T25%pc are very closely related. ► T25%pc can be predicted from %PC0.
