Maize (Zea mays L), also called as ‘corn’ or ‘makki’ in India, is believed to have been domesticated in Mexico about 9000 years ago. It arrived in India along with the Portuguese in the 16th century when they brought maize crop here from Europe. However, the real push to the cultivation of maize came during the rule of the British in early 19th century when they decided to develop commercial crops in India and brought maize varieties to India.
Maize is a versatile, most produced grain in the world, grown throughout the year and across different agro-climatic regions of the world.
In India, it is the third most important cereal crop after wheat and rice. Andhra Pradesh, Karnataka, Rajasthan, Maharashtra, Bihar and Uttar Pradesh are the major producers of the maize.
Maize Flour in Traditional Indian Cooking
Maize flour is made by grinding of maize kernels. It is used to make the ‘rotis’ and also as a binding agent for pudding or ‘pakoras’. It is used as thickener of soups, sauces, stews and other such recipes.

3/6. Flour corn is made of soft starch endosperm and thin pericarp. Dried corn is ground to make flour. It is popularly called ‘makki ka atta’ in north India.
4/6. Flint corn is called so because of hard outer covering which protects the softer endosperm. It is generally grown in South America where it is also known as ‘Indian Corn’.
5/6. Dent corn is soft due to high starch content and is identified with small dent present at the crown of each kernel. This type of corn is generally used to feed the livestock.

Corn Flour Vs Corn Starch
The process of grinding corn kernels into fine powder is called corn flour. It has the same taste as corn grain. However, Corn starch is made by removing protein, fat and fiber components of the corn and using only the starchy endosperm. It does not have any taste.
Corn flour is generally mixed with the warm water to prevent formation of lumps in flour whereas corn starch is mixed with the cold water for the same purpose. As a thickening agent, corn starch scores more than corn flour.
