Corn construction

Last updated

Corn construction refers to the use of corn (maize) in construction. The tassel, leaf, silk, cob in husks, and the stalk are the parts of corn. According to the Michigan Department of Agriculture, "corn can be made into fuel, abrasives, solvents, charcoal, animal feed, bedding for animals, insulation, adhesives, and more. The kernel is used as oil, bran, starch, glutamates, animal feed, and solvents. The silk is combined with other parts of the corn plant to be used as part of animal feed, silage, and fuels. Husks are made into dolls and used as filling materials. The stalk is used to make paper, wallboard, silage, syrup, and rayon (artificial silk)." [1]

History

Corn has long been used in manufacturing. There were a number innovations in the United States in the early 1900s. For example, Henry Ford's conceptual Model U car featured tires with corn-based filler and a corn-based fabric roof.

The Corn Palace, a building in Mitchell, South Dakota, is decorated with murals and designs made from corn and other grains.

Materials

Husks

The outer husk of corn can be used to make corn husk dolls, txalaparta musical instruments, and other crafts. Husks are used as the wrapper for tamales. It is also used in South American countries as a cigarette rolling 'paper'.

Corncobs

Corncobs, the core of corn ears, are very absorbent. They have been used to make inexpensive smoking pipes, and to transport various materials. Ground corn cobs make an effective blasting media, are friendly to the environment, and delicate while maintaining abrasive capacity.

Corncobs are increasingly being used as a low-cost, environmentally friendly insulation material for houses.

Cornstarch

Goodyear BioTRED tires are made using a biologic polymer derived from cornstarch as the filler.

Corn kernels

Corn kernel burning stoves have found increasing popularity following the rise in natural gas and fuel oil prices. Large corn furnaces are capable of heating any size building, and fueling generators to produce electricity. Corn kernels are a natural pellet, which makes corn less expensive and more readily available than wood byproduct pellets. Manufactured pellets sold out in 2005, while corn is readily available for a much better price. Heat savings go up to 75% over natural gas or fuel oil.

Plastics

Recently, corn has been used to make biodegradable containers. Corn can be used to create non-petroleum plastic, which is often compostable.

Straw is an agricultural byproduct consisting of the dry stalks of cereal plants after the grain and chaff have been removed. It makes up about half of the yield of cereal crops such as barley, oats, rice, rye and wheat. It has a number of different uses, including fuel, livestock bedding and fodder, thatching and basket making.

<span class="mw-page-title-main">Sweet corn</span> Variety of corn

Sweet corn, also called sweetcorn, sugar corn and pole corn, is a variety of corn grown for human consumption with a high sugar content. Sweet corn is the result of a naturally occurring recessive mutation in the genes which control conversion of sugar to starch inside the endosperm of the corn kernel. Sweet corn is picked when still immature and prepared and eaten as a vegetable, rather than field corn, which is harvested when the kernels are dry and mature. Since the process of maturation involves converting sugar to starch, sweet corn stores poorly and must be eaten fresh, canned, or frozen, before the kernels become tough and starchy.

Silage is a type of fodder made from green foliage crops which have been preserved by fermentation to the point of acidification. It can be fed to cattle, sheep, and other such ruminants. The fermentation and storage process is called ensilage, ensiling, or silaging. Silage is usually made from grass crops, including maize, sorghum, or other cereals, using the entire green plant.

<span class="mw-page-title-main">Baby corn</span> A type of cereal grain

Baby corn is a cereal grain taken from corn (maize) harvested early while the stalks are still small and immature. It typically is eaten whole—including the cob, which is otherwise too tough for human consumption in mature corn—in raw, pickled, and cooked forms. Baby corn is common in stir fry dishes.

<span class="mw-page-title-main">Corn on the cob</span> Whole sweet corn, consumed as food

Corn on the cob is a culinary term for a cooked ear of sweet corn (maize) eaten directly off the cob. The ear is picked while the endosperm is in the "milk stage" so that the kernels are still tender. Ears of corn are steamed, boiled, or grilled usually without their green husks, or roasted with them. The husk leaves are removed before serving.

<span class="mw-page-title-main">Corncob</span> Central core of corn ear

A corncob, also called corn cob, cob of corn, or corn on the cob, is the central core of an ear of corn. It is the part of the ear on which the kernels grow. The ear is also considered a "cob" or "pole" but it is not fully a "pole" until the ear is shucked, or removed from the plant material around the ear. It is also the green husk that goes outside the corn.

Corn stover consists of the leaves, stalks, and cobs of maize (corn) plants left in a field after harvest. Such stover makes up about half of the yield of a corn crop and is similar to straw from other cereal grasses; in Britain it is sometimes called corn straw. Corn stover is a very common agricultural product in areas of large amounts of corn production. As well as the non-grain part of harvested corn, the stover can also contain other weeds and grasses. Field corn and sweet corn, two different types of maize, have relatively similar corn stover.

Animal feed is food given to domestic animals, especially livestock, in the course of animal husbandry. There are two basic types: fodder and forage. Used alone, the word feed more often refers to fodder. Animal feed is an important input to animal agriculture, and is frequently the main cost of the raising or keeping of animals. Farms typically try to reduce cost for this food, by growing their own, grazing animals, or supplementing expensive feeds with substitutes, such as food waste like spent grain from beer brewing.

<span class="mw-page-title-main">Maize</span> Genus of grass cultivated as a food crop

Maize, also known as corn in North American and Australian English, is a cereal grain first domesticated by indigenous peoples in southern Mexico about 10,000 years ago. The leafy stalk of the plant gives rise to inflorescences which produce pollen and separate ovuliferous inflorescences called ears that when fertilized yield kernels or seeds, which are botanical fruits. The term maize is preferred in formal, scientific, and international usage as the common name because it refers specifically to this one grain whereas corn refers to any principal cereal crop cultivated in a country. For example, in North America and Australia corn is often used for maize, but in England and Wales it can refer to wheat or barley, and in Scotland and Ireland to oats.

<span class="mw-page-title-main">Dent corn</span> Variety of corn

Dent corn, also known as grain corn, is a type of field corn with a high soft starch content. It received its name because of the small indentation, or "dent", at the crown of each kernel on a ripe ear of corn. Reid's Yellow Dent is a variety developed by central Illinois farmer James L. Reid. Reid and his father, Robert Reid, moved from Brown County, Ohio, to Tazewell County, Illinois, in 1846 bringing with them a red corn variety known as "Johnny Hopkins", and crossed it with varieties of flint corn and flour corn. Most of today's hybrid corn varieties and cultivars are derived from it. This variety won a prize at the 1893 World's Fair.

<span class="mw-page-title-main">Corn husk doll</span>

A corn husk doll is a Native American doll made out of the dried leaves or "husk" of a corn cob. Maize, known in some countries as corn, is a large grain plant domesticated by indigenous peoples in Mesoamerica in prehistoric times. Every part of the ear of corn was used. Women braided the husks for rope and twine and coiled them into containers and mats. Shredded husks made good kindling and filling for pillows and mattresses. The corncobs served as bottle stoppers, scrubbing brushes, and fuel for smoking meat. Corn silk made hair for corn husk dolls. Corn husk dolls have been made by Northeastern Native Americans probably since the beginnings of corn agriculture more than a thousand years ago. Brittle dried cornhusks become soft if soaked in water and produce finished dolls sturdy enough for children's toys. Making corn husk dolls was adopted by early European settlers in the United States of America. Corn husk doll making is now practiced in the United States as a link to Native American culture and the arts and crafts of the settlers.. In other cultures, corn dollies are used to celebrate Lammas. Corn dollies are magical charms thought to protect the home, livestock, and personal wellness of the maker and their family. They may be a home for the spirit of the crop. The tradition pertains to the idea that the crop of grain has a spirit that loses its home after the final harvest and it is therefore to be invited and housed in the home over the winter before being returned to the earth in spring for the next crop.

Corn silk is a common Stigma maydis, the shiny, thread-like, weak fibers that grow as part of ears of corn (maize); the tuft or tassel of silky fibers that protrude from the tip of the ear of corn. The ear is enclosed in modified leaves called husks. Each individual fiber is an elongated style, attached to an individual ovary. The term probably originated sometime between 1850 and 1855.
