Unveiling the World of Millets in 2023: A Comprehensive Exploration

Table of Contents


Millet, a cereal grass with a rich history spanning over 4,000 years across Asia and Africa, holds a prominent position in agriculture. Western regions use Millet for pasture and hay, while developing nations rely on it as a crucial food staple. Recognizing its importance, the United Nations Food and Agricultural Organization has designated 2023 as the “year of the millets.”

Characteristics and Types:

Millet plants, usually annuals, range from 30 to 130 cm (1 to 4 feet) in height. Pearl millet, a towering variety, can reach up to 3 meters (10 feet). Their inflorescences vary, displaying spikes, racemes, or panicles adorned with clusters of small florets. Millet seeds, except for pearl millet, retain their hulls after threshing, usually in a creamy white hue.


  • Pearl Millet (Bajra in India): Thrives in low fertility and limited moisture soils, serving as a staple food crop in India and Africa.
  • Little Millet: Primarily a food crop in India.
  • Proso Millet: Commonly used in birdseed mixtures and consumed as a cereal food in Asia and Eastern Europe, ripening within 60–80 days post-sowing.
  • Foxtail Millet: Grown for hay in North America and Western Europe, crucial as a food crop in China and various Asian nations.
  • Finger Millet: An essential food grain in southern Asia and parts of Africa.
  • Japanese Millet: Primarily cultivated in Japan and the United States as a hay crop.

Nutritional Content:

Millet grains boast high carbohydrate content, with protein ranging from 6 to 11 percent and fat from 1.5 to 5 percent. Known for their distinct taste, millets are commonly consumed in flatbreads and porridges, similar to rice.

Benefits and Adaptability:

Millets exhibit greater tolerance for poor soils and drought compared to other grains, requiring fewer inputs like fertilizers and pesticides. Certain deep-rooted millet varieties contribute to erosion reduction and desertification mitigation.

Cultural Significance:

Boza, a traditional fermented drink in Eastern Europe and the Middle East, features wheat, millet, or bulgur as key ingredients.

Wheat and Poales

 Wheat, a crucial cereal grain, plays an indispensable role in global agriculture and belongs to the grass family (Poaceae) within the order Poales.

Poales - Grass Order of Flowering Plants

Poales, a significant order housing over 18,000 species of monocotyledons, encompasses major groups like the grass group, cattail group, and sedge group.

Grass Group (Families within Poales):

  • Poaceae (Grasses): Encompassing over 10,000 species in 668 genera, this family dominates global vegetation, found in diverse habitats worldwide. Economically crucial, providing essential grains like rice, corn, and wheat.
  • Restionaceae: Boasting 50 genera and 520 species.
  • Centrolepidaceae: Comprising 3 genera and 35 species of small grasslike plants.
  • Anarthriaceae and Ecdeiocoleaceae: Represent low herbs in southwestern Australia.

Cattail Group (Families and Genera)

  • Sparganiaceae (Bur Reed Family): Characterized by spherical flower heads and creeping rootstocks.
  • Typhaceae (Cattail Family): Recognizable for an elongate flowering spike, commonly cultivated for ornamental purposes.

Sedge Group (Families within Poales)

  • Cyperaceae (Sedge Family): Generally annual or perennial herbs with wind-pollinated or self-pollinated flowers, encompassing 4,350 species.
  • Juncaceae: Including rushes (Juncus) and woodrushes (Luzula), globally used for weaving.
  • Thurniaceae: Featuring two genera, Thurnia and Prionium, distributed in South America and South Africa.

In summary, wheat, a vital cereal grain, is part of the grass family (Poaceae) within the order Poales, encompassing various significant plant groups with ecological, economic, and cultural importance.

Oats (Avena sativa)

  • Oats, scientifically known as Avena sativa, are domesticated cereal grasses in the Poaceae family, cultivated primarily for their edible starchy grains

Characteristics and Cultivation

Annual plants with a height reaching up to 1.5 meters (5 feet). Oats can grow in various soil conditions, including sandy, low-fertility, or highly acidic soils. Relatively resistant to diseases and pests, but susceptible to rust and anthracnose on stems and leaves.

Uses and Products

  • Human Consumption: Rolled oats are used primarily for oatmeal. Oat flour is utilized in cookies and puddings. Grains are high in carbohydrates, containing about 13 percent protein and 7.5 percent fat.
  • Livestock Feed: Oats are used in pure form and in mixtures for livestock feed.
  • Industrial Use: Oat hulls serve as a source of furfural, a chemical used in various solvents.

In conclusion, oats play a significant role in both human and animal nutrition, offering a versatile grain source with diverse applications in food and industry.


Malt is a grain product used in beverages and foods as a basis for fermentation and to add flavor and nutrients, prepared from cereal grains, with barley being the primary choice.

Major Uses

  • Brewing of Beer: Largest quantities of malt are used in brewing beer.
  • Distilled Alcohol Production: Malt is used to make distilled alcohol for whiskey and other beverages.
  • Food Products: Malt extracts are used for flavor, enzyme activity, and starch content in various food products.

Malting Process

The malting process involves steeping, germination, and kilning, where enzymes produced during germination break down starch into simpler carbohydrates, mainly malt sugar (maltose). In brewing, malt is added to a cereal mash for its enzymes to convert starches into maltose.

Malt Extract

Produced by mashing malt, removing solids, and concentrating the aqueous fraction. A thick syrup containing sugars, vitamins, and minerals.

Historical Aspect

London brewers departed from the traditional process of making beer from successive extracts in the 18th century.

Specialty Malts

Controlled heating of wetted or dry malt produces specialized malts (e.g., crystal malt, chocolate malt) to enhance beer color and flavor.

In summary, malt is a versatile ingredient crucial in brewing, distilled alcohol production, and various food products, contributing to flavor, enzyme activity, and nutritional content.
