Corn oil is composed mainly (99% of the refined or 96% of the crude
oil) of acylglycerols (mono-, di- and primarily tri-), and has 59% polyunsaturated
(PUFA), 24% monounsaturated (MUFA) and 13% saturated
fatty acid (SFA). The PUFA to SFA ratio (P/S) is about 4.6. Corn oil has one
of the highest PUFA levels after sunflower, safflower, walnut and wheat
germ oil (Landers and Rathmann, 1981). The primary PUFA is linoleic
acid (C18:2n−6), with a small amount of linolenic acid (C18:3n−3)
giving a n−6/n−3 ratio of 83. Corn oil contains a significant amount
of ubiquinone and high amounts of gamma-tocopherols (vitamin
E) (Dupont et al., 1990). These high contents of PUFA and vitamin E
may contribute to the health benefits of corn oil consumption
