The methyl esters of the fatty acids were analysed by gas chromatography (Hewlett–Packard 5790) on a 12 m 0.2 mm capillary column coated with Carbowax PEG 20 (Demirbas, 2009). The physico- chemical properties such as saponification value, acid value, iodine value and peroxide value of the tomato seed oils were determined.
