Abstract
Hydrogenated vegetable oil (EI-Nakhletane) and two different animal fats (cows Butter and Bulfallo Samn) were analysed by gas liquid chromatography to separate, identify and determine hydrocarbon. sterol and tocopherol in order to detect adulteration of fats. This investigation indicated that hydrogenated vegetable oil is characterized by the absence of cholestrol and E-tocopherol and the presence of C24. Cow Butter is characterized by the presence of hydrocarbon C28 and buffalo-Samn by the presence of hydrocarbon C21.
