Today, the use of natural antioxidants is attracting the attention of consumers. Black plum peel is the waste of plum processing and is the source of antioxidants. In this research, the effect of black plum peel extract (BPPE) (0, 400, and 800 ppm) as a natural antioxidant and storage time (0, 8, and 16 days) on the oxidative stability parameters (peroxide value, free fatty acids, thiobarbituric acid, conjugated dienes, and carbonyl value) of sunflower oil with response surface methodology (RSM) method was studied.
