Swell, L., P. E. Schools, Jr. and C. R. Treadwell, Am. Crude oil contains approximately 85% unsaturated and saturated fatty acids. Oils derived commercially from corns grown in other countries are generally more saturated than those from USA corn. Smith, E. D., and A. Corn oil: benefits and its composition. Corn oil, hydrogenated Corn Oil, Corn Oil, Organic Corn Oil, Virgin Corn Oil, and Margarine are compared on the basis of fatty acid composition and triglyceride structure, including configurational isomerism of unsaturated fatty acids. Article  PubMed Google Scholar, Beadle, J.B., Just, D.E., Morgan, R.E. 26, 272–7 (1949). Almost all corn oil is expeller-pressed, then solvent-extracted using hexane or 2-methylpentane (isohexane).

After extraction, the corn oil is then refined by degumming and/or alkali treatment, both of which remove phosphatides.Alkali treatment also neutralizes free fatty acids and removes color (bleaching). Final steps in refining include winterization (the removal of waxes), and deodorization by steam distillation of the oil at 232–260 °C (450–500 °F) under a high vacuum.[1]. A total of 103 samples of refined corn oil produced over a period of 2.5 years were analyzed by the alkali isomerization procedure. A., Margaret L.

This is a more expensive product since it has a much lower yield than the combination expeller and solvent process, as well as a smaller market share. Almost all corn oil is expeller-pressed, then solvent-extracted using hexane or 2-methylpentane (isohexane). within one unit of the average value, 123.6. Although much of our experience has been with the alkali isomerization method, the GLC technique is preferred because it is simpler and yields more information on fatty acid composition. Corn oil is twice as good as olive and sunflower in terms of vitamin E, which is the strongest antioxidant and prevents premature aging. Available data suggests that 100 g of corn oil (industrial and retail) contains: 27.58% of monounsaturated fat, 54.68% of polyunsaturated fat, and … A number of corn oils were analyzed by GLC.
