Corn or maize oil is the oil extracted from the germ of corn or maize. It has a variety of uses, both in cooking and non-cooking applications. Its high smoke point makes it valuable for cooking and deep frying. When it comes to industries, it is used as cleaner and lubricant, as well as to make fuel for gasoline and diesel.

This oil is widely available and most of the times it is chosen due to its accessible price, compared to other vegetable oils.

Market overview and production

The industrial process through which corn oil is obtained is called “wet milling”, because the corn grain is pre-soaked to soften the kernel and begin separating it into its constituent parts. It’s then fed through a series of mills and centrifuges. These separate the germ, starch, fiber, and gluten proteins. The corn oil that comes out of the wet-milling process is primarily intended for human consumption. The other process is called “dry milling”, but the corn oil obtained is used supplement feed, or as the basis of biodiesel.

The region of South America and the Caribbean represents more than 10% of cereal production (mainly maize) in the world, being Argentina, Brazil and Mexico the main producers.

Currently, in the Argentinian national ranking of oil production corn oil occupies the 4^th place. Argentina is ranked in the 7th place worldwide. Along the country there are three corn oil processing plants, all located in Buenos Aires.
