Although corn is a very common food, it is known as a "golden vegetable" and is also known as a longevity food. Corn is rich in nutrients. Some people may not know that the calcium content per 100 grams of corn is very small compared to cow's milk.

The glutathione contained in corn is a longevity factor discovered by experts in recent years, which produces an anti-aging ingredient - glutathione oxidase with the participation of selenium. At the same time, the nutrients in the corn germ tip can promote the metabolism of the human body, so it is also known as the same kind of beauty food.

Everyone knows that corn is sweet and waxy, so what is the difference between sweet corn and waxy corn? Maybe a lot of people don't know yet.

◎The taste is different

The reason why these two kinds of corn taste are different is mainly because of the difference in the ingredients and content they contain. The starch content in waxy corn reaches seventy or eighty percent, and most of them are amylopectin, so its taste is soft and glutinous, easy to chew, and it is very suitable for people who do not have good teeth.

The starch content in sweet corn is very small, and most of it contains sucrose, fructose, glucose and water-soluble polysaccharides, which makes it sweeter and juicy.

◎There is a gap in nutritional value

Under normal circumstances, the nutritional value of sweet corn is slightly higher than that of waxy corn. Why? The main reason is that sweet corn not only contains a lot of sugar, but at the same time, it is also a large number of nutrients, such as carotene, riboflavin, protein, linoleic acid, folic acid and a variety of vitamins and minerals, it contains much more nutrients than waxy corn. Therefore, there is a gap in the nutritional value of waxy corn.

◎The cooking method is also different

Whether it is sweet corn or boiled corn, it is recommended to cook it before eating, but the cooking method of both types of corn is also particular. Waxy corn can be soaked in water for a short period of time before being boiled, and then steamed or boiled. After the corn kernels are soft, take out the pot and put it in the steamer, and wait for the water to dry before eating, so that the waxy corn will taste very good and is very popular.

There are also some tips for cooking sweet corn. First of all, when boiling sweet corn, the outer skin should not be completely peeled, one or two layers should be left, and the corn silk should not be thrown away, even the belt must be boiled.

Secondly, sweet corn should be pot under cold water, add a small spoon of edible salt to the water, and you can also add a little baking soda. Corn cooked with salt can make the corn kernels look fuller, the light saltiness of eating can highlight the sweetness of the corn, and baking soda can better release the nutrients in the corn.

Also, don't boil sweet corn for too long, after the water is boiled, turn on low heat and simmer for 20 minutes, then take it out and let it cool, and then peel the skin when you eat it, which can prevent the moisture from losing too quickly and the taste worse.

◎The warranty period is different

Sweet corn cannot be stored for a long time because it contains more juice and sugar, whereas waxy corn is different because it has a lot of starch content, so it can be stored for a lot longer than sweet corn.

Of course, whether you like to eat sweet corn or waxy corn, please pay more attention to the following 2 points:

1. Don't eat deformed corn
