Maize, Zea mays L. (corn), is the most abundantly produced cereal in the world. It is grown in every continent except Antarctica. About 50 species exist and consist of different colors, textures, and grain shapes and sizes. White, yellow, and red are the most common cultivated maize types. The white and yellow varieties are preferred by most people depending on the region. Maize, which was domesticated in central Mexico around 1500 BC, was introduced into Africa around 1500 AD, and spread to every corner of the continent within a relatively short period and is now Africa’s most important cereal crop.
