May I ask if sweet corn is genetically modified corn?
No, it is a variant of corn screened out, that is, a variety of corn mutated by itself, not man-made genetically modified varieties. There are also sweet glutinous types, as well as colored corn. Several criteria for judging genetically modified foods: size. Traditionally, tomatoes have a certain size, for example: a small tomato as big as the head of a thumb is definitely genetically modified. Another example is soybeans, also known as soybeans, is to make tofu, soymilk that kind of beans, the shape should be like animal offal: the waist of the look, a little flat, but now the soybeans, all the round, a lot of big, like peas like soybeans, the yield is very high, it is genetically modified. Colors. Anything different from conventional is definitely GMO, like colored cotton, colored peppers. Yield. Genetically modified crops generally yield quite a bit more than conventional crops in the beginning years. Season. With the exception of greenhouse vegetables, other foods that are out of season are prone to be genetically modified. Pests. Any crop that pests like to patronize is not genetically modified, and any crop that pests are afraid of, i.e., no pests, or very few pests, is genetically modified.
