Grain

A wheat is a small, hard, dry seed, with or without a layer of stomach or accompanying fruit, harvested for human or animal consumption. A wheat crop is a grain-producing plant. The two main types of commercial grain crops are cereals and nuts.

After being harvested, dried grains are more durable than other staple foods, such as starchy fruits (plantains, breadfruit, etc.) and tubers (sweet potatoes, cassava, and more). This resistance has made the grains very suitable for industrial agriculture, as they can be mechanically harvested, transported by train or boat, stored for long periods in silos, and milled for flour or pressed for oil. Thus, major global commodity markets exist for canola, corn, rice, soybeans, wheat, and other grains but not for tubers, vegetables, or other crops.

Grains and cereals

Grains and cereals are identical to caryopses, fruits of the grass family. In agronomy and trade, the seeds or fruits of other plant families are called seeds if they resemble caryopses. For example, spinach is sold as "wheat spinach", and the spinach product can be described as "whole grains". The pre-Hispanic civilization of the Andes has a wheat-based food system but, at higher altitudes, no grains are cereals. All three original grains to the Andes (kaniwa, kiwicha, and quinoa) are broad-leaved plants rather than grasses such as corn, rice, and wheat.

Classification

Grain of cereals

All cereal plants are members of the grass family (Poaceae). Cereal grains contain lots of starch, carbohydrates that provide dietary energy.

Warm season cereals

• finger millet
• fonio
• the leaf of the rombong
• Japanese Millet
• Job's Tears
• kodo milet
• corn (corn)
• milet
• millet pearl
• proso millet
• sorghum

Winter Cereal

• barley
• oats
• rice
• rye
• spelled
• teff
• triticale
• wheat
• wild rice

Pseudocereal grains

Grains of broad-leafed plant families (dikot):

• spinach (Amaranth family)
• buckwheat (Smartweed family)
• chia (Mint Family)
• quinoa (Amaranth family, formerly classified as Goosefoot family)
• kaÃÆ' ± ± iwa
• kiwicha

Nuts or seeds, family members of peas, have a higher protein content than most other plant foods, about 20%, while soybeans have as much as 35%. As with all other whole plant foods, nuts also contain carbohydrates and fats. General pulses include:

• chickpeas
• normal beans
• regular peas (garden peas)
• fava beans
• lentils
• lima bean
• lupine
• green beans
• nuts
• pigeon pea
• runner seed
• soybeans

Oilseeds

Seed oil seeds grow mainly for the extraction of their vegetable oils. Vegetable oil provides food energy and some essential fatty acids. They are also used as fuel and lubricants.

Mustard Family

• black mustard
• Indian mustard
• rapeseed (including canola)

Aster Family

• safflower
• sunflower seeds

Other families

• flaxseed (Flax family)
• flaxseed (hemp family)
• poppy seeds (Poppy family)

The historical impact of grain farming

Because the grains are small, hard and dry, the grains can be stored, measured, and transported more readily than other food crops such as fresh fruits, roots, and tubers. The development of grain farming allows the excess of food to be produced and stored easily which can lead to the creation of the first permanent settlement and the division of society into the classroom.

Occupational safety and health

Those who handle grain at a grain facility may face many dangers and job exposures. Risks include wheat traps, where workers are awash in grain and can not erase themselves; explosions caused by fine particles of grain dust, and falling.
