What are popcorn kernels and how do they differ from other corn types?
Popcorn kernels are a specific variety of corn known as Zea mays everta. This unique type of corn has a hard outer shell, or pericarp, which allows it to withstand high pressure when heated. Unlike other corn varieties, such as sweet corn or field corn, popcorn kernels have a higher moisture content trapped inside, which is essential for the popping process. Other types of corn don’t have the same structural integrity and won’t pop when heated.
When heated, the moisture within the popcorn kernel vaporizes, creating steam and building up pressure inside the kernel. Eventually, when the inner pressure exceeds the kernel’s ability to contain it, the kernel explodes, puffing up into the familiar popcorn shape. This popping process is what sets popcorn apart as a unique snack experience compared to other types of corn.
How are popcorn kernels cultivated?
Popcorn cultivation begins with selecting the right seeds. These seeds are typically planted in well-drained soil with a warm climate, as popcorn requires specific growing conditions to thrive.
