    This phenomenon is even stronger with (most types of) Maize (excluding sweet corn). It requires heavy processing to be turned into glucose sirup or anything resembling edible food. By default, the grains are extremely durable and very difficult to digest.

    But this is essentially what protects it from insects and fungus. Because the grains are so hard to digest by default, they can only be eaten by humans who have the tools to heavily process them before eating; for everyone else it’s essentially uninteresting as a food source and that prevents mold and insects.

      What type of corn are you referring to? I’m not familiar with the history of corn, but what you’re saying doesn’t match my experiences with any variety

      Dent corn is used as livestock feed, and is generally considered the less edible version. Sweet corn can be eaten by humans raw. Basically every variety I’ve ever seen can be eaten if boiled long enough

        Sweet corn is a mutation that was only really cultivated in the late 1700s. Before that dent and flint corn were the norm. These corns require nixtamalization to soft the corn and then need boiling, grinding, and cooking to make something like tortillas.

        Yeah, the effect is stronger for dent corn.

        Dent corn can last upwards of 20 years when stored correctly.

        I’m not sure what that number is for other cereals but i guess it’s less long.

      Corn (Maize) is a selected grass. (Teosinte) Wheat is also a grass (Emmer) which hasn’t been nearly as modified.

      The american indigenous people cultivated and developed corn over 10,000 some years. An ear of corn can be boiled and eaten. Wheat? Not so much.
