Maize, also known as corn, is one of the most versatile cereal crops grown globally. It is consumed in various forms such as popcorn, sweet corn, cornmeal, and corn flour, and also used extensively as animal feed. In addition to being a food staple, maize plays a critical role in the production of industrial products like starch, corn oil, bioethanol, and sweeteners.
Maize is classified into types such as flint corn, dent corn, popcorn, and sweet corn, based on kernel texture and protein composition. In commercial trade, quality grades for maize depend on its intended use—whether for human consumption (food grade) or animal feed (feed grade).

Ensuring the safety and quality of stored maize (corn) is crucial for maintaining its market value and meeting both domestic and international regulatory requirements. Various contaminants and residues can impact the grain’s usability, making regular quality checks and pest control measures essential.
To preserve grain quality and eliminate hidden insect infestations, fumigation is a critical process during storage and before export.
