Evaluation of Nine Oil Crops for Fatty Acid Constituents of their Oils

Oils of nine oil crops were evaluated concerning their composition of the fatty acids. the obtained results revealed that palm oil had the highest content of palmitic acid (45.10%) and canola oil had the lowest (3.90%). the highest stearic acid content was found in palm oil (4.70%) and the lowest was found in canola oil (1.90%). olive oil had the highest content of oleic acid (71.10%) and the lowest content was found in cotton seed oil (17.60%). linoleic acid percentage ranged from 68.0% in sunflower to 9.40% in palm oil. linolenic acid percentage ranged from 52.0% in flax oil to 0.00 % in peanut oil. the lowest saturated fatty acids percentage was 6.80% in canola while the highest percentage was found in palm oil (51.50 %). as for the total unsaturated fatty acids values, they were found to be 93.20%, 90.0%, 87.30%, 84.50%, 82.90%, 82.0%, 74.70%, 72.0% and 48.60% in the oils of canola, flax, sunflower, soybean, olive, maize, peanut, cotton and palm, respectively.
