Corn / Maize
Corn, also known as maize, is a cereal grain that is widely cultivated throughout the world. It is a staple food in many countries and is used in a variety of ways, including as a source of animal feed, fuel, and industrial materials.
Corn is believed to have originated in Mexico over 7,000 years ago and has since been introduced to other parts of the world. Today, it is grown in a variety of climates and is one of the most widely produced crops in the world.
Corn is a rich source of carbohydrates, fiber, vitamins, and minerals, and is a popular ingredient in many food products. It can be eaten in its natural state, cooked, or processed into a variety of products, including cornmeal, corn starch, corn syrup, and corn oil.
In addition to its use as a food product, corn is also used in a variety of other applications. It is a major source of animal feed and is used to produce ethanol, a biofuel that is used as an alternative to gasoline. Corn is also used in the production of industrial materials, such as plastics, adhesives, and textiles.
Overall, corn is a versatile and important crop that plays a significant role in both the food and non-food industries.
The specifications of corn can vary depending on the intended use and the country of origin. However, here are some general specifications for corn:
-
Moisture content: Typically, the moisture content of corn should be between 12-14%.
-
Foreign matter: The amount of foreign matter in corn should not exceed 2% of the total weight.
-
Broken kernels: The number of broken kernels in corn should not exceed 3-5% of the total weight.
-
Aflatoxin: Aflatoxin is a harmful substance produced by fungi that can grow on corn. The maximum allowable level of aflatoxin in corn varies depending on the country of origin and the intended use. In the United States, the maximum allowable level of aflatoxin in corn for human consumption is 20 parts per billion (ppb).
-
Protein content: The protein content of corn can vary, but it is generally around 8-10%.
-

-
Size: The size of corn kernels can vary, but they should be relatively uniform in size and shape.
These are some of the common specifications for corn, but again, they can vary depending on the intended use and country of origin. It is important to consult the relevant standards and regulations for specific requirements.
