The Story of Corn History Detective for Students

 


Many Kinds of Corn

Genetic diversity of cornToday there are many kinds of corn. The most common types are flint, dent, sweet and of course popcorn.


Flint corn, also known as Indian corn, has a hard outer shell and kernels with a range of colors from white to red. Today, most flint corn is grown in Central and South America.

Dent corn, often called "field corn" is often used as livestock feed. It is also the main kind of corn used when making industrial products and various foods. It can be either white or yellow.

Sweet CornSweet corn is often eaten on the cob or it can be canned or frozen. Sweet corn is seldom processed into feed or flour. Sweet corn gets its name because it contains more sugar than other types of corn.

Popcorn, a type of flint corn, has a soft starchy center that is covered by a very hard shell. When popcorn is heated the natural moisture inside the kernel turns to steam that builds up enough pressure for the kernel to explode. When the kernel explodes the white starchy mass that you like to eat forms.
