From the results, it can be inferred that alcoholic solvents enable extracting corn oils with a typical fatty acid composition; aqueous ethanol leads the extraction of higher levels of tocopherols and tocotrienols and absolute isopropanol has the best performance in the extraction of carotenoids .

Therefore, the aim of this study was to evaluate the extraction of corn germ-bran oil with these alcohols and their aqueous solutions, at temperatures from 50 up to 80°C. The results showed that the oil and carbohydrate extraction yields are influenced by the type and hydration level of the solvent and temperature, while this last variable has not shown influence on liquid holdup.

In order to understand the corn oil extraction process and how corn oil is extracted during ethanol production, it helps to first understand how corn is processed. Broadly speaking, corn processing is broken up into wet milling and dry milling. Processing Corn by Wet Milling. Wet milling is primarily used to make food ingredients: sweeteners, starch, corn oil, and so on.

How Corn Oil is Extracted from the Corn. Oil is being pressed from the germ using a heated screw press, which can yield as much as 50 percent of the germ oil. Then the pressed oil should be extracted in the corn oil extraction plant, the remaining oil is stripped from the "press cake" with the solvent hexane, a volatile by-product of gasoline production.

Corn oil is oil extracted from the germ of corn . Its main use is in cooking, has high nutritional value, where its high smoke point makes refined corn oil a valuable frying oil. It is also a key ingredient in some margarines. Corn oil is generally less expensive than most other types of vegetable oils.

An efficient process for recovering high quality corn oil from corn germ. The process involves pre-treating corn germ by Rehydration, conditioning and, optionally flaking. This is followed by extrusion, which is the core operation in the preparation of corn germ for corn oil recovery. Water is provided up front in the process, prior to extrusion.

Production. Almost all corn oil is expeller-pressed, then solvent-extracted using hexane or 2-methylpentane . The solvent is evaporated from the corn oil, recovered, and re-used. 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 .
