It is also a key ingredient in some margarines. Corn oil is generally less expensive than most other types of vegetable oils.
Corn refiners established the process of separating corn kernels into their component parts to produce a variety of value-added products. The four main component such as oil, protein, starch, and fiber are the primary product from the corn wet-milling process. The Associated Manufacturers of Products from Corn was formed in 1913 when the group ...
Maize is widely cultivated throughout the world, and a greater weight of maize is produced each year than any other grain. [78] In 2020, total world production was 1.16 billion tonnes , led by the United States with 31.0% of the total (table).
Field corn, also known as cow corn, is a North American term for maize (Zea mays) grown for livestock fodder (silage and meal), ethanol, cereal, and processed food products. The principal field corn varieties are dent corn , flint corn , flour corn (also known as soft corn) which includes blue corn ( Zea mays amylacea ), [ 1 ] and waxy corn .
The production of corn (Zea mays mays, also known as "maize") plays a major role in the economy of the United States. The US is the largest corn producer in the world, with 96,000,000 acres (39,000,000 ha) of land reserved for corn production. Corn growth is dominated by west/north central Iowa and east central Illinois. Approximately 13% of ...
This durability has made grains well suited to industrial agriculture, since they can be mechanically harvested, transported by rail or ship, stored for long periods in silos, and milled for flour or pressed for oil. Thus, the grain market is a major global commodity market that includes crops such as maize, rice, soybeans, wheat and other grains.
It can be a source of protein, energy, and pigments for livestock, and is used in pet foods for digestibility. Corn gluten meal is occasionally confused for corn gluten feed, which instead has approximately 22% crude protein and is a mixture of bran, steep liquor, and maize germ oil from the milling process.

World production of main vegetable oils by main producers . Typical productivity of some oil crops, measured in tons (t) of oil produced per hectare (ha) of land per year (yr). Oil palm is by far the highest yielding crop, capable of producing about 4 tons of palm oil per hectare per year.
