Dent, popcorn and sweet corn are the most popular types grown in the United States. Corn is classified by its kernel type, with the exception of pod corn. Click on the images below to learn more about the six corn varieties.
Flint
Known as calico corn, this variety is harder than dent corn and
sometimes used as decorative corn because of the multiple kernel
colors. While the ears of this corn type are long and slender, grown
in Latin America, South America, and parts of Europe, it has not been
commonly grown in the United States since colonization. Flint corn is
processed into cornmeal, hominy, and grits.
Flour
Flour corn has been traced back to Aztec and Incan civilizations,
the soft kernels on this corn were grounded into flour after they had
been dried.
Dent
Also known as field corn, it spotted by the dent in the crown
of each kernel of corn. Dent corn is used in grain products, animal
feed, and some liquors due to the high starch low sugar content.
Almost always yellow, but sometimes the kernels can be white.
Sweet
Sweet corn is a variety with high sugar content and is the result
of a naturally occurring mutation in the genes that control the
conversion of sugar to starch in the corn kernel. While most corn is
picked when it reaches full maturity so it can be turned into a grain,
sweet corn is picked while it is immature so it can be eaten as a
vegetable. Since it is harvested before the kernels dry out, sweet
corn must be eaten fresh, canned, or frozen.
Popcorn
Regarded as the oldest surviving type of corn, this variety of corn
that expands and puffs when heated. The kernels are shaped like rice,
with pointed tips, and contain a certain amount of moisture and oil,
which is why it can be popped as freshly popped corn and in popcorn
confections.
Pod
This variety is not grown commercially and mainly used for ornamental purposes since each kernel is enclosed in a husk.
