چکیده مقاله:

The purpose of the current study was to determine the physicochemical properties and fatty acid profile of sunflower and soy bean oil extracted by Soksleh methods. The physicochemical properties were evaluated by peroxide value, acidity, soapy number, soapy material and non soapy material. The fatty acid compositions of sunflower and soy bean oil were identified and determined using Gas chromatography (GC). The results of physicochemical properties exhibited that except of peroxide value which soybean oil was higher than sunflower oil, all of factors were similar. The results of GC demonstrated that sunflower and soy bean oils were found to be good sources of poly unsaturated fatty acids with total poly unsaturated fatty acid 86.81 %and 83.11% respectively. According to the results linoleic and palmitic acid were most abundant unsaturated and saturated fatty acids in both samples respectively. The level of linolenic acid in soybean oil (6.5 %) was higher than sunflower oil (0.11%).
