Wheat (Triticum spp.)
One of the most widely cultivated cereal crops globally, wheat is used for flour production in baking bread, pastries, and other baked goods. It comprises diverse varieties including durum wheat, used for pasta, and soft wheat, for cakes and pastries.
Rice (Oryza sativa)
Serving as a staple food for over half of the world’s population, rice comes in various types such as long-grain, medium-grain, and short-grain, each with unique culinary properties. It is integral to many Asian, African, and Latin American cuisines.
Maize (Corn) (Zea mays)
A versatile crop used for food, feed, and industrial purposes, maize is utilized in the production of cornmeal, corn syrup, ethanol, and animal feed. It plays a significant role in the diets of many cultures worldwide.
Barley (Hordeum vulgare)
Primarily used for brewing beer and whiskey, barley is also utilized as animal feed and in soups, stews, and salads. It is known for its tolerance to diverse environmental conditions.
Oats (Avena sativa)
High in dietary fiber and known for their heart-healthy properties, oats are commonly consumed as oatmeal or rolled oats for breakfast. They are also used in baking and as livestock feed.
Rye (Secale cereale)
Thriving in colder climates and poor soils, rye is used for making rye bread, whiskey, and as a cover crop to prevent soil erosion. It contains more fiber and nutrients compared to wheat.
Sorghum (Sorghum bicolor)
An important cereal crop in arid and semi-arid regions, sorghum is used for food, fodder, and ethanol production. It is a gluten-free grain gaining popularity in various food products.
Millet (Pennisetum glaucum)
A drought-tolerant cereal crop grown in dry regions, millet is consumed as a staple food in many parts of Africa and Asia. It is also used as birdseed and in traditional alcoholic beverages.
Quinoa (Chenopodium quinoa)
A pseudocereal known for its high protein content and nutritional value, quinoa is a gluten-free grain alternative gaining popularity in health-conscious diets. It is native to the Andean region of South America.
Teff (Eragrostis tef)
An ancient grain native to Ethiopia and Eritrea, teff is used to make injera, a traditional Ethiopian flatbread. It is rich in essential nutrients like iron and calcium.
Spelt (Triticum spelta)
An ancient grain with a nutty flavor and high nutritional value, spelt is tolerant to poor soils and adverse weather conditions. It is used in baking, cooking, and as livestock feed.
Emmer (Triticum dicoccum)
An ancient wheat variety with a high protein content, emmer was historically cultivated in the Fertile Crescent region. It is used in baking, brewing, and as a cover crop.
