The process of corn germ oil making

Corn germ oil, also known as maize oil, is a very versatile culinary oil extracted from the germ of corn.

The corn kernel is separated into its component parts: the fiber-rich outer hull, the starch-and-protein-rich endosperm, and the oil-rich corn germ. the kernels are steeped in slightly acidified water, which loosens the hull and makes the endosperm swell up; then they’re ground coarsely. A centrifuge removes the lighter corn germ from the rest of the corn. The remaining grounds are passed through a series of screens. The corn endosperm, grinds into small particles because it’s soft, passes through the screens. The larger pieces of hull stay behind.

After being cleaned and dried, the corn germ is pressed to extract the corn germ oil, then use a solvent such as hexane to extract more oil from the pressed corn germ.

The oil is called crude corn oil , after it’s filtered, bleached, and cleaned to purify it, get  the light-yellow, neutral-smelling refined corn oil.
