dc.description.abstractCombined use of antioxidants is highly effective in preventing oxidation. In this study, combined effects of ethanolic extracts of turmeric (T) and potato peel (PP), a- tocopherol (a), ss- carotene (ss), ascorbyl palmitate (AP), citric acid (C) and lecithin (L) were evaluated in sunflower oil. The antioxidant activities of these substances were evaluated individually and with binary and ternary combinations with different concentrations. The combined effect of AP (1000 ppm) and T (5000 ppm) was strong when all oxidative evaluation analysis were considered: lowering peroxide value by 3.5-fold, almost doubling the induction time and having the highest protection factor percentage (94.95%). AP in blends was found efficient in terms of protecting sunflower oil against oxidation and was not present in non-efficient mixtures. L followed it regarding efficiency. In the mixtures consisted of AP-,L-PP (83.7% protection factor (PF)) and AP-L-T (19.6% PF), namely in the presence of identical concentrations of PP and T, superior PF for the mixture containing PP was determined, which was thought to be based on the higher hydrophilicity of PP. C and a in mixtures were not effective enough to retard the oxidation. Combinations of PP-L-ss (-23.8%) and T-L-a (-19.5%) showed negative relationships. The results also demonstrated concentration-dependency of the antioxidants in terms of antioxidant efficiency. Our findings about the efficient interactions between different natural compounds could provide information to develop natural plant-based antioxidant mixtures with greater effectiveness than their single use in retarding oil oxidation.en_US
