Do you need to thaw frozen corn before cooking?

It depends on the situation. If it is frozen cooked corn, it is best to thaw it in a cool place for about 10 minutes before cooking, which will make it taste better. If it is frozen raw corn, you don't need to thaw it. Peel off the thick outer skin and leave the thin inner skin. Wash it and cook it directly in the pot. Boil it for about 20 minutes after the water boils. Boil corn in cold water. It is best to leave a few layers of inner skin and silk on the corn for a more fragrant taste.

How to tell if corn is spoiled

You can look at the color of the corn kernels. If the corn kernels are gray-black, it means the corn has gone bad. You can also look at the corn germ. If there is black matter in the germ, it means the corn has gone bad. If the corn smells rotten, it means the corn has gone bad.

When corn goes bad, it will produce aflatoxin, a substance that is highly toxic, carcinogenic and difficult to remove, so bad corn cannot be eaten.

Where are the nutrients in corn mainly stored?

The nutrients of corn are mainly stored in the endosperm. Corn is a monocotyledonous plant, and its seeds are generally composed of seed coat, embryo and endosperm. The endosperm is located inside the seed coat, accounting for about 80% to 85% of the total weight of the seed, and stores the main nutrients of corn.

The nutrients of monocot seeds are mainly stored in the endosperm, while the nutrients of dicot seeds are mainly stored in the cotyledons. Corn belongs to monocots, and the corn kernel is composed of epidermis, endosperm, plumule and root cap.

Corn has extremely high nutritional and medicinal value. Its vitamin content is about 5 to 10 times that of rice and wheat. Compared with traditional grain crops, corn has strong drought resistance, cold resistance, and environmental adaptability, making it an excellent grain crop.
