Abstract
The autoxidation of purified fish oil in the presence of different concentrations of o-hydroxyl, o-methoxy, and alkyl ester derivatives of p-hydroxybenzoic at 35 – 55 °C was evaluated by different kinetic parameters including the stabilizing factor as a measure of effectiveness, the oxidation rate ratio as a measure of strength, and the antioxidant activity which combines the two parameters. Methyl gallate as the most reactive antioxidant participated only in the main reaction of chain termination (ROO● + InH ROOH + In●). Gallic acid, ethyl protocatechuate, protocatechuic acid, vanillic acid, and syringic acid, respectively, were able to protect fish oil against oxidation in terms of the extent of their participation in the pro-oxidative side reactions of chain initiation (InH + ROOH In● + RO● + H2O and InH + O2 In● + HOO●) and the antioxidative side reactions of chain propagation (In● + ROO● In-OOR and In● + In● products).
