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.
