Corn is a grass native to America, which the people in Central Mexico began cultivating at least 7,000 years ago. Corn was a staple in the diet of many Indian groups. They used all parts of the corn. The sugary leaves were used as a sort of chewing gum, immature corn was their vegetable and dry, mature kernels were ground into flour. Today, corn is grown on every continent except Antarctica. Corn is the No. 1 grain crop in the United States. Most corn grown in the U.S. is a variety called field corn or dent corn, which is used as livestock feed and processed into a variety of products. The corn most of us eat is called sweet corn.
Corn is planted in the spring from a seed called a “kernel.” The seed will grow into a stalk which then produces ears of corn. The ears of corn mature over the summer. When they are ready to harvest, in late August or early September, they will turn downward to the ground. Producers use a machine called a combine to harvest the corn. Once in the combine, the ears enter a sheller. The sheller is a metal cylinder that rotates at a high speed and removes all husks and kernels from the cob. The corn is then loaded onto trucks and transported to a nearby grain elevator. The corn is stored at the elevator in bins until it is sold and shipped out for processing. An ear of corn averages 800 kernels in 16 rows. An acre of corn yielding 100 bushels produces approximately 7,280,000 kernels. Illinois and Iowa are the top producing states.
There are more than 3,500 different uses for corn. Primary products are cornstarch, sweeteners, food and industrial items. There are many edible uses for corn including aspirin, marshmallows, ice cream, cereals, corn chips, cornmeal, baking mixes and more.
Some non-edible products that contain or are made from corn include ethanol, book binding, ink, glue, shoe polish, cosmetics, fireworks, paint, paper, crayons, chalk, toothpaste, soap, candles, batteries and charcoal. There are more uses being found every day for corn.
Corn is a member of the vegetable group. Everyone should have 3-5 servings from this group each day. Corn is low in fat and calories and provides almost three grams of dietary fiber per ear. The starch found in corn is a carbohydrate.
Our best customers are Japan, Mexico, Taiwan, Canada, Egypt, and Columbia. The U.S. is the largest field corn exporter, and we use 80% of what we produce and export the other 20%.
TYPES OF CORN
1. Field corn (dent corn)
Hard shell and full of starch
99% corn grown in the U.S.
Livestock and poultry feed
Processed into a variety of products such as:
Corn syrup, cornstarch, sorbitol, glue, fireworks, crayons, chalk, cosmetics, ink
2. Sweet corn
Less than 1% of the corn grown in U.S.
Sugary seeded type of corn
Corn we eat:
Corn on the cob, canned corn, frozen corn
U.S. is number 1
The corn kernel is composed of 4 main parts
Pericarp: Waterproof outer covering
Endosperm: Largest part of kernel where energy is stored and it provides starch
Germ: Contains the genetic information for the plant, and it is used for corn oil
Tip cap: Attaches the kernel to the cob
**Include graphic of the corn kernel showing 4 main parts. Maybe something like that??**
