Field corn, unlike sweet corn, is primarily used as animal feed, in industrial products, and as a key ingredient in processed foods due to its high starch content and tough texture. It is not typically eaten fresh off the cob.
Primary Uses of Field Corn:
-
Animal Feed: This is the most significant use. Field corn provides a readily available and energy-rich source of nutrition for livestock, including cattle, pigs, and poultry.
-
Ethanol Production: Field corn is fermented to produce ethanol, a biofuel that can be used as an alternative or additive to gasoline.
-
Processed Foods and Industrial Products:
-
Cornstarch: A versatile ingredient used as a thickener, stabilizer, and binding agent in many foods and industrial applications (e.g., paper production, textiles).
-
Corn Syrup & High Fructose Corn Syrup (HFCS): Sweeteners used extensively in the food and beverage industry.
-
Corn Oil: Extracted from the corn kernel germ, used for cooking and in various industrial processes.
-
Other Products: Field corn derivatives are found in products like plastics, adhesives, and pharmaceuticals.
-
Food Preparation (Nixtamalization):
Field corn undergoes a process called nixtamalization, where it is soaked and cooked in an alkaline solution (usually lime water). This process:
- Improves the nutritional value of the corn (makes niacin more bioavailable).
- Softens the kernels.
- Alters the flavor.
Nixtamalized corn is then used to make:
-
Masa: Ground into masa, used for making tortillas, tamales, and other traditional dishes, particularly in Latin American cuisine.
-
Grits: A coarsely ground corn product, often served as a porridge.
-
Cornbread: Baked bread made from cornmeal (which can be made from ground field corn).
-
Mush: A cooked cornmeal porridge.
In summary, while you wouldn't typically eat field corn directly off the cob, it's an incredibly versatile crop that's vital for animal agriculture, energy production, the food industry, and various manufactured products.
