Corn kernels are the fruits of corn (called maize in many countries). Maize is a grain, and the kernels are used in cooking as a vegetable or a source of starch. The kernel comprise endosperm, germ, pericarp, and tip cap.
One ear of corn contains roughly 800 kernels in 16 rows. Corn kernels are readily available in bulk throughout maize-producing areas. They have a number of uses, including food and biofuel. Corn consist of the husk, and the silk, often mistaken for the husk.
Corn kernels are the fruits of maize. Maize is a grain, and the kernels are used in cooking as a vegetable or a source of starch. The kernels can be of various colors: blackish, bluish-gray, purple, green, red, white and yellow. One ear of corn contains roughly 800 kernels in 16 rows. One hundred bushels of corn can contain upwards of 7,280,000 kernels. Corn kernels are readily available in bulk throughout maize-producing areas. Transportation and packaging of dried clean corn kernels to non-producing areas adds to the social media.
The kernel of maize consists of a pericarp (fruit wall) fused to the seed coat. This type of fruit is typical of the grasses and is called a caryopsis. Maize kernels are frequently and incorrectly referred to as seeds. The kernels are about the size of peas, and adhere in regular rows round a white, pithy substance, which forms the ear.
About 82 percent of the corn kernel’s dry weight consists of endosperm. Starch is the primary source and it most widely used part of the kernel. It is known as the key component in fuel, sweeteners, bioplastics and other products.
The germ is the only living part of the corn kernel and also called its embryo. It consists the important genetic information, vitamin, enzymes and minerals for the plant to grow. Germ account 25 percent of the corn oils and it is the valuable part of the kernel.
The tip cap is the attachment point of the kernel to the corn cob, where the nutrient and water flow, and this is the only part that not covered by the pericarp. It contains fiber.
Corn is a popular food throughout the world in many forms. It is used in breakfast cereals in the Western world (as corn flakes) and it is a grain that can be eaten raw off the cob, although it is usually preferred cooked. It may be fed to animals or humans. In the United States, for economic reasons such as government subsidies, corn is the basis of many products, in the form of high fructose corn syrup, in favor of cane sugar. A genetic variant that accumulates more sugar and less starch in the ear is consumed as a vegetable and is called sweet corn.
Corn kernels are used as pelletized fuel for pellet stoves and furnaces. Corn kernels are a natural pellet, which gives them an economic advantage over other man-made biomass pellets and wood pellets.
The use of corn and other grains as a renewable biofuel may have environmental and cost benefits, compared to other energy sources, and may create additional forms of revenue for farmers and other economic industries. However, the use of corn as a fuel stock may increase the price of corn and have adverse effects on corn as a food stock.
