Characteristics and fatty acid compositions of the lipid components of the main fractions (germ, starch, gluten, and fiber) obtained in the wet milling of corn and grain sorghum kernels have been determined. Dauqan et al. On the other hand, good fats such as polyunsaturated and monounsaturated fatty acids (PUFAs and MUFAs) tend to lower this risk. These differences were found to be similar in both grains.

These oils are treated with hydrogen to achieve stabilization. Corn oil (maize oil) is oil extracted from the germ of corn ().Its main use is in cooking, where its high smoke point makes refined corn oil a valuable frying oil. 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. The oil constitutes about half of the germ (embryo) of the corn kernel, which is separated from the rest of the kernel during the operation of milling to produce meal, animal Healthful oils are an essential part of all diets. Other industrial uses for corn oil include soap, salve, paint, erasers, rustproofing for metal surfaces, inks, textiles, nitroglycerin, and insecticides. High-oil corn (HOC) genotypes adapted to temperate and subtropical regions containing up to 8% oil have been developed. Corn oil is also a feedstock used for biodiesel. In fact, the corn oil is more likely to boost this rate. 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. Herbert E. Longenecker.
