Cereal-based foods form the basis of human nutrition world-wide. Their main task is the supply of nutrition energy as they are rich in high polymer carbohydrates, mainly starch. Besides, cereals can and do contribute a significant amount of biologically active constituents that promote beneficial physiological effects like dietary fiber and their fractions, vitamins and polyphenols, to name only a few. There is a large variety of cereal species that has been and could be used for human nutrition, as well as starch-rich seeds that can be used like cereals, the co-called pseudocereals.

Priority regions for research on dryland cereals and legumesVIDEO ON THE TOPIC: What are Legumes?
A grain is a small, hard, dry seed , with or without an attached hull or fruit layer, harvested for human or animal consumption.
The two main types of commercial grain crops are cereals and legumes. After being harvested, dry grains are more durable than other staple foods , such as starchy fruits plantains , breadfruit , etc. This durability has made grains well suited to industrial agriculture , since they can be mechanically harvested , transported by rail or ship, stored for long periods in silos , and milled for flour or pressed for oil. Thus, major global commodity markets exist for maize , rice , soybeans , wheat and other grains but not for tubers, vegetables, or other crops.
Grains and cereal are synonymous with caryopses , the fruits of the grass family. In agronomy and commerce, seeds or fruits from other plant families are called grains if they resemble caryopses. For example, amaranth is sold as " grain amaranth ", and amaranth products may be described as "whole grains". The pre-Hispanic civilizations of the Andes had grain-based food systems but, at the higher elevations, none of the grains was a cereal. All three grains native to the Andes kaniwa , kiwicha , and quinoa are broad-leafed plants rather than grasses such as corn, rice, and wheat.
All cereal crops are members of the grass family Poaceae. As is the case with all other whole plant foods, pulses also contain carbohydrate and fat. Common pulses include:. Oilseed grains are grown primarily for the extraction of their edible oil. Vegetable oils provide dietary energy and some essential fatty acids.
Because grains are small, hard and dry, they can be stored, measured, and transported more readily than can other kinds of food crops such as fresh fruits, roots and tubers. The development of grain agriculture allowed excess food to be produced and stored easily which could have led to the creation of the first permanent settlements and the division of society into classes. Those who handle grain at grain facilities may encounter numerous occupational hazards and exposures.
Risks include grain entrapment , where workers are submerged in the grain and unable to remove themselves;  explosions caused by fine particles of grain dust ,  and falls.

Bioactive Molecules in Food pp Cite as. Legumes are part of the human edible panel since prehistory times but the remains that reached our last centuries were all from a period posterior to fire domestication. In all parts of the world where human civilizations developed, pulses were associated with cereals and the combination of their proteins managed to cover the essential amino-acid requirements of Humans and animals. Legumes gathering more than 19, different species, all present high protein content due to specific symbiosis with rhizobia and arbuscular mycorrhizae present in the soils. These associations are thought to originate from first symbiotic events dating from more than 60 million years before present.
Legumes and Cereals
Cereal processing , treatment of cereals and other plants to prepare their starch for human food , animal feed , or industrial use. Cereals, or grains, are members of the grass family cultivated primarily for their starchy seeds technically, dry fruits. Wheat, rice, corn maize , rye, oats, barley, sorghum, and some of the millets are common cereals; their composition is shown in the table. Starch , a carbohydrate stored in most plants, is a major constituent of the average human diet, providing a low-cost energy source with good keeping qualities. Cereals are high in starch, which may be used in pure or flour form. Starches are also obtained from such root sources as potatoes and from the pith of tropical palm trees. Various starches are used commercially in food processing and in the manufacture of laundering preparations, paper, textiles, adhesives, explosives, and cosmetics.
Without the use of flour mills, many of the grains consumed in a variety of different forms would not be available to the general public. The bread loaves, pancakes, muffins, pasta, and all other products that come from grain would not be so easy to obtain without a reliable and efficient way to change them from their natural state into an edible product. What is a flour mill? The most commonly eaten types of grains are cereals and legumes. Legumes are beans, soybeans, lentils, peas, even peanuts. These need to be processed in order to be transformed into consumable products for the masses, but they do not have to be broken down to the extent that cereal grains are. Due to the physical structure of cereal grains such as wheat, barley, and rye, they have to be broken down by machines in order to produce products like flour. Flour mills, which are sometimes referred to as grain mills, break down the grain into smaller parts and separate them. These machines can range in size from a small version that will fit in the kitchen, to a large commercial version made for manufacturing space.

A cereal is any grass cultivated grown for the edible components of its grain botanically, a type of fruit called a caryopsis , composed of the endosperm , germ , and bran. The term may also refer to the resulting grain itself specifically " cereal grain ". Cereal grain crops are grown in greater quantities and provide more food energy worldwide than any other type of crop  and are therefore staple crops. Edible grains from other plant families, such as buckwheat Polygonaceae , quinoa Amaranthaceae and chia Lamiaceae , are referred to as pseudocereals. In their natural, unprocessed, whole grain form, cereals are a rich source of vitamins , minerals , carbohydrates , fats , oils, and protein. When processed by the removal of the bran, and germ, the remaining endosperm is mostly carbohydrate. In some developing countries , grain in the form of rice , wheat , millet , or maize constitutes a majority of daily sustenance. In developed countries , cereal consumption is moderate and varied but still substantial. The word cereal is derived from Ceres , the Roman goddess of harvest and agriculture. Agriculture allowed for the support of an increased population, leading to larger societies and eventually the development of cities. It also created the need for greater organization of political power and the creation of social stratification , as decisions had to be made regarding labor and harvest allocation and access rights to water and land.

How Does A Flour Mill Operate?
Starch is also an essential nutritional component of human and animal diets and has various food and non-food industrial applications. Starch is a primary insoluble polymeric carbohydrate produced by higher plants and consists of amylose and amylopectin as a major fraction. Legume seeds are an affordable source of not only protein but also the starch, which has an advantage of being resistant starch compared with cereal, root, and tuber starch. For these reasons, legume seeds form a good source of resistant starch-rich healthy food with a high protein content and can be utilized in various food applications. The genetics and molecular details of starch and other carbohydrate components are well studied in cereal crops but have received little attention in legumes. In order to improve legume starch content, quality, and quantity, it is necessary to understand the genetic and molecular factors regulating carbohydrate metabolism in legume crops. In this review, we assessed the current literature reporting the genetic and molecular basis of legume carbohydrate components, primarily focused on seed starch content. We provided an overview of starch biosynthesis in the heterotrophic organs, the chemical composition of major consumable legumes, the factors influencing starch digestibility, and advances in the genetic, transcriptomic, and metabolomic studies in important legume crops. Further, we discussed breeding and biotechnological approaches for the improvement of the starch composition in major legume crops.
Food processing is the transformation of raw ingredients into food, or of food into other forms. Food processing typically takes clean, harvested crops or butchered animal products and uses these to produce attractive, marketable and often long shelf-life food products.
