Physical properties of wheat quality include grain mass, hardness, grain size and shape and color. Chemical characteristics of wheat include moisture content, protein (gluten) content, amylase content and fibre content.

Wheat Types

Wheat is a widely cultivated cereal grain that belongs to the grass family Poaceae. There are several types of wheat, each with its unique characteristics and uses. Here are some of the most common wheat types:

1. Common Wheat (Triticum aestivum):

   • Also known as bread wheat, it is the most widely grown wheat species globally.
   • Used to make a variety of products, including bread, pasta, and pastries.
   • Has a high gluten content, which gives dough elasticity and helps bread rise.

2. Durum Wheat (Triticum durum):

   • Primarily used to make pasta, couscous, and semolina.
   • Has a high protein content and a distinctive amber color.
   • Known for its firm texture and ability to hold its shape during cooking.

3. Hard Red Winter Wheat (Triticum aestivum):

   • Grown in regions with cold winters, such as the Great Plains of the United States.
   • Has a high protein content and is used for making bread, rolls, and other baked goods.
   • Known for its hardiness and ability to withstand harsh weather conditions.

4. Hard Red Spring Wheat (Triticum aestivum):

   • Grown in regions with shorter growing seasons, such as the northern United States and Canada.
   • Has a high protein content and is primarily used for making bread and pasta.
   • Known for its strong gluten content and good baking qualities.

5. Soft Red Winter Wheat (Triticum aestivum):

   • Grown in milder climates, such as the southeastern United States.
   • Has a lower protein content compared to hard wheat varieties.
   • Used for making pastries, cookies, and cakes.
   • Known for its soft texture and mild flavor.

6. White Wheat (Triticum aestivum):

   • A type of common wheat with a light-colored kernel.
   • Has a lower protein content than red wheat varieties.
   • Primarily used for making flour, pastries, and crackers.
   • Known for its mild flavor and versatility.

These are just a few examples of the many wheat types cultivated worldwide. Each variety has its unique properties and is suited for specific culinary purposes.

The wheat standard for human consumption refers to the quality standards set for wheat grains intended for human consumption. These standards ensure that the wheat is safe, wholesome, and suitable for human consumption. The specific parameters and criteria may vary depending on the region or country, but generally, the standards cover various aspects of wheat quality, including:

1. Physical Characteristics:

   • Wheat grains should be free from visible defects such as mold, insect damage, or discoloration.
   • The size, shape, and weight of the grains may also be specified to meet certain requirements.

2. Moisture Content:

   • The moisture content of wheat grains is crucial for storage and quality preservation.
   • Standards specify the maximum moisture level to prevent spoilage and maintain the grain’s stability during storage.

3. Purity:

   • Wheat grains should be free from foreign materials such as weed seeds, other grains, or dirt.
   • The purity standards help ensure the quality and consistency of the wheat.

4. Chemical Composition:

   • Standards may specify the levels of certain chemical components in wheat, such as protein, ash, and gluten content.
   • These components influence the nutritional value and functional properties of wheat flour.

5. Microbiological Criteria:

   • Wheat grains should be free from harmful microorganisms, such as bacteria or fungi, that could pose a health risk.
   • Microbiological standards help ensure the safety of wheat for human consumption.

6. Pesticide Residues:

   • Standards may regulate the levels of pesticide residues in wheat grains to ensure food safety.
   • Compliance with these standards helps minimize the presence of harmful chemicals in wheat products.

7. Nutritional Value:

   • Some standards may specify the minimum nutritional requirements for wheat grains, such as vitamin and mineral content.
   • This ensures that wheat-based products contribute to a balanced diet.

By adhering to these standards, the wheat industry ensures that consumers have access to safe, high-quality wheat products that meet their nutritional needs and preferences.

The global wheat trade is a complex and dynamic market, influenced by various factors such as production levels, weather conditions, government policies, and geopolitical events. In 2022, the top 10 wheat exporting countries accounted for a significant share of the global wheat exports.
