Its main use is in cooking, where its high smoke point makes refined corn oil a valuable frying oil. Winkler et al. Cottonseed oil is cooking oil from the seeds of cotton plants of various species, mainly Gossypium hirsutum and Gossypium herbaceum, that are grown for cotton fiber, animal feed, and oil.. Cotton seed has a similar structure to other oilseeds such as sunflower seed, having an oil-bearing kernel surrounded by a hard outer hull; in processing, the oil is extracted from the kernel. General Composition of Corn Oil 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. the tocopherols prevent the oil from oxidizing rapidly. It is sometimes used as a carrier for drug molecules in pharmaceutical preparations. A total of 103 samples of refined corn oil produced over a period of 2.5 years were analyzed by the alkali isomerization procedure. The second major fatty acid is monounsaturated oleic that, in some HOC, nearly equals the amounts of linoleic, opening the possibility of developing new high-oleic cultivars. Authors M … it has a low melting point of 18°c to 10°c. The composition of commercial corn oil from USA corn is remarkably constant. 3. Similarly, it is also true that not all fats are identical.
