How to make soybean oil ?

Soybean oil

Soybean contains about 19 percent oil. To extract soybean oil from the seed, the soybeans are cracked, adjusted for moisture content, rolled into flakes, and solvent-extracted with commercial hexane. Afterwards, the oil is refined and blended for various applications – and often hydrogenated.

It is often that commercial brands mix soybean oil with cheaper ones to make the end product more affordable. But there are unrefined soybean oil products, cold-pressed and expeller-removed. They usually have a stronger flavor, but are said to retain a higher nutritional value than refined oils.
