Abstract: This study was carried out in order to probe the extent of oxidative alterations in Sunflower Oil (SFO), subjected to light and dark storage conditions with, and without added vitamins, over a period of 16 weeks storage. The magnitude of oxidative changes was monitored by the periodical measurement of acid value, peroxide value, iodine value, Density and color throughout storage time. The acid value of sunflower oil increased from initial value 3.74 mg KOH/g to 4.92 mg KOH/g. kept in light and 4.00 mg KOH/g kept in dark. the acid value for oil samples kept in light and dark with added vitamin C, vitamin E and equal amount mixed from vitamin C and E was decreased for 16 weeks. Like the acid value, the peroxide value of sunflower oil increased from 7.46 meq O2/kg to (9.34 and 8.62) meq O2/kg, for oil samples kept in the same conditions with that mentioned in acid value. Unlike the acid value, the Iodine value of sunflower oil decreased from 140.5gI2/100g oil to (97.87 and 107.73) gI2/100g, the initial density 0.9026 g/cm-1 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, peroxide value and Iodine 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. In conclusion, this study has been able to show storage in the light can affect oil stability and minimizes the potency of vitamins in oils, fats or fat-containing products. Therefore, storing in dark (packaging with material protect light) and supporting with antioxidants is the best way to maintain the quality of oils during storage and domestic uses.
