Abstract
The autoxidation of purified triacylglycerols obtained from fish, canola, and olive oils in the presence of different concentrations of hydroxytyrosol at 60–100 °C was evaluated by different kinetic parameters including the stabilizing factor (F) as a measure of effectiveness, the oxidation rate ratio (ORR) as a measure strength, and the antioxidant activity (A) which combines the F and ORR parameters. The overall performance of hydroxytyrosol was attributed to the main reaction of chain termination (ROO· + InH = ROOH + In·) as competed with the main oxidation reaction of chain propagation (ROO· + RH = ROOH + R·) and, additionally, the antioxidative side reactions of chain propagation (In· + ROO· = In − OOR and In· + In· = products ), and the pro-oxidative side reaction of chain initiation (InH + ROOH = In· + RO· + H2O) in some cases.
