4. Conclusion
From the present study, it was concluded that Senjed peel aqueous extract can stabilize cold-pressed sesame oil effectively at a concentration of 750 ppm. It inhibits the thermal deterioration of oil by improving its hydrolytic stability, inhibit the lipid oxidation and reduce the loss of polyunsaturated fatty acids (PUFAs). Senjed peel aqueous extract at concentration of 750 ppm has stabilization efficacy comparable to the common synthetic antioxidant TBHQ at its legal limit. Therefore, Senjed peel aqueous extract can be recommended as the potent source of natural antioxidant for the stabilization of food and food product, especially edible vegetable oils rich in unsaturated fatty acids.
