The main objective of this research work is to study the effect of antioxidant on preventing the oxidative spoilage of sunflower oil. A sample of sunflower oil was produced from seeds brought from Sudanese agricultural area, the Al-Jazeera project area was investigated separately properties, the physical properties such as color, density and some chemical properties such as acid value and peroxide value upon storing the oil sample in day light zone following the same industrial storage condition. For a period of time ranged from 8 to 16 weeks. Antioxidant such as vitamin C and vitamin E were treated with the stored oil. The change in the physiochemical properties of oil samples were determined. The normal routine analysis of the oil such as GC-MS was done to oils under tests. Concerning GC-MS the major components of the oils were found to be palmitic acid, palmitolic acid, steric acid, Oleic acid and linoleic acid. The average acid value for Al-Jazeera sunflower oil was found to be (3.29, mg KOH/g), prior to the storage period and decreased to (0.31 and 0.50 mg KOH/g), when storing the oil for 8 and 16 weeks respectively. Also the peroxide value of sunflower oil sample was found to be (7.28 meq O2/kg), prior to the storage period and (2.73 and 5.66 meq O2/kg) when storing the oil for 8 and 16 weeks respectively. The initial density 0.9026 g/ml was increase with added antioxidants vitamins, the density values was calculated after storage time and observing in the ranges recommended by standard for edible vegetable oils. Like the density, the color of oils was not change because the oil is rich by the color pigments. However, the vitamins added of fresh sunflower oils increase the oxidation stability. Changes in acid value and peroxide value obtained shows that the oxidative deterioration levels of oils were different between storage conditions. The results of the present study show that light acts as a major catalyst in accelerating the development of rancidity in oils. Also, the addition of vitamins to oil can increase the oxidation stability of oils during storage
