Probing the synergistic effects of rutin and rutin ester on the oxidative stability of sardine oil.

Multicomponent antioxidant mixture is proved to be highly effective in imparting oxidative stability to the edible oil. It is believed that the high efficacy of those mixtures is due to the synergistic effect exhibited by two or more components. The current study aims to analyse the synergistic effect of a flavonoid and its corresponding ester in improving the oxidative stability of -3 PUFA rich sardine oil.
