Popcorn, a versatile snack

Popcorn, also known as popping corn, is a type of corn (maize, Zea mays var. everta) that expands from the kernel and puffs up when heated. Popcorn is able to pop because, like amaranth grain, sorghum, quinoa, and millet, its kernels have a hard moisture-sealed hull and a dense starchy interior. When heated, pressure builds within the kernel, and a small explosion (or "pop") is the end result. Some strains of corn are now cultivated specifically as popping corns.

There are various techniques for popping corn. Along with prepackaged popcorn, which is generally intended to be prepared in a microwave oven, there are small home appliances for popping corn. These methods require the use of minimally processed popping corn.

A larger-scale, commercial popcorn machine was invented by Charles Cretors in the late 19th century.

Unpopped popcorn is considered nonperishable and will last indefinitely if stored in ideal conditions.

Depending on how it is prepared and cooked, some consider popcorn to be a health food, while others caution against it for a variety of reasons. Popcorn can also have non-food applications, ranging from holiday decorations to packaging materials.

History

Corn was first domesticated in Mexico 9,000 years ago from a wild grass.

During the Great Depression, popcorn was fairly inexpensive at 5–10 cents a bag and became popular. Thus, while other businesses failed, the popcorn business thrived and became a source of income for many struggling farmers, including the Reddenbacher family, namesake of the famous popcorn brand. During World War II, sugar rations diminished candy production, and Americans compensated by eating three times as much popcorn as they had before.

At least six localities (all in the Midwestern United States) claim to be the "Popcorn Capital of the World;": Ridgway, Illinois; Valparaiso, Indiana; Van Buren, Indiana; Schaller, Iowa; Marion, Ohio; and North Loup, Nebraska. According to the USDA, corn used for popcorn production is specifically planted for this purpose; most is grown in Nebraska and Indiana, with increasing area in Texas.

As the result of an elementary school project, popcorn became the official state snack food of Illinois.

January 19 is National Popcorn Day in the United States.

Jargon for Differences in Popcorn

In popcorn jargon, a popped kernel of corn is known as a "flake." Two shapes of flakes are commercially important. "Butterfly" or "snowflake" flakes are irregular in shape and have a number of protruding "wings". "Mushroom" flakes are largely ball-shaped, with few wings. Butterfly flakes are regarded as having better mouthfeel, with greater tenderness and less noticeable hulls. Mushroom flakes are less fragile than butterfly flakes and are therefore often used for packaged popcorn or confectionery, such as caramel corn. The kernels from a single cob of popcorn may form both butterfly and mushroom flakes; hybrids that produce 100% butterfly flakes or 100% mushroom flakes exist, the latter developed only as recently as 1998. Growing conditions and popping environment can also affect the butterfly-to-mushroom ratio.

Consumption in the USA

Popcorn balls (popped kernels stuck together with a sugary "glue") were hugely popular around the turn of the 20th century, but their popularity has since waned. Popcorn balls are still served in some places as a traditional Halloween treat. Cracker Jack is a popular, commercially produced candy that consists of peanuts mixed in with caramel-covered popcorn. Kettle corn is a variation of normal popcorn, cooked with white sugar and salt, traditionally in a large copper kettle. Once reserved for specialty shops and county fairs, kettle corn has recently become popular, especially in the microwave popcorn market. The popcorn maker is a relatively new home appliance, and its popularity is increasing because it offers the opportunity to add flavours of the consumer's own choice and to choose healthy-eating popcorn styles.

Some popular brands of popcorn in the United States are Orville Redenbacher's, Act II, Jiffy Pop (all three of which are brands of the ConAgra Foods conglomerate), Pop Secret, Candy Land Gourmet, Jolly Time, Aussie Crunch, Newman's Own, Dale and Thomas and Pop Weaver.

The world's largest popcorn ball was unveiled in October 2006 in Lake Forest, Illinois. It weighed 3,415 pounds (1,549 kg), measured 8 feet (2.4 m) in diameter, and had a circumference of 24.6 ft (7.5 m).
