alt Hacker NewsThere are 4 types of corn. Dimple/dent corn, pop corn, sweet corn, and flint corn. Each variety can be eaten. Prepared differently of course as they have different starches and flavors but the vast majority of corn fields in the United States grow dent corn for feed and biofuels.
Fair point, there’s many types of corn but for anyone interested.
Sweet Corn: For Fresh Eating and therefore harvested with a high moisture content which hurts preservation without freezing and total yield.
Dimple is a Field corn, harvested later resulting in a dryer product, lasts longer and has a higher yield.
Flint Corn: Mostly decorative as it looks cool, but again still edible after grinding.
Heirloom: lots of shapes and sizes but significantly lower yield.
Popcorn: A tiny slice of the market but pops when heated.
