Investigating relationship between water production and interfacial activity of γ-oryzanol, ethyl ferulate, and ferulic acid during peroxidation of bulk oil

Abstract In this study, lecithin (as a surfactant) was added to promote the inhibitory-mechanism of γ-oryzanol, ethyl-ferulate and ferulic acid (based on interfacial phenomena) so as inhibit oxidation stripped sunflower oil. Monitoring amount water production byproduct showed that content lipid system increased remarkably through progress. Lecithin enhanced critical concentration hydroperoxides in reverse micelles, compared basic state (14.8 vs. 9.2 mM), thereby improving hydrogen-donating mechanism antioxidants. The size micelles progressively during oxidation, while two breakpoints were pointed out growth, i.e. at end initiation propagation phases. Based kinetic data, highest antioxidant activity (23.4), (15.5) γ-oryzanol (13.7). Generally, (~ 65%) by performance
