Sweet, sweet, soft and waxy. These four words mean corn. Because of its high nutritional value and good taste, corn is loved by many people and eaten by almost every household. Therefore, although corn can be seen everywhere in supermarkets, vegetable markets and other places, and it is so cheap and grounded, not as small and exquisite as apples and pears, and its nutritional value is also high, it does not hinder people's love for corn. There are many kinds of corn. What are their functions? What's the difference between them?

What nutrition does corn have?

1. Basic nutrition

& gt& gt is mainly carbohydrate, accounting for 73.2%, followed by protein with 8.5% and fat with 4.3%.

& gt& gt contains vitamins, minerals, riboflavin and other nutrients, among which the vitamin content is 5- 10 times that of rice and flour.

The cellulose content in>& gt cereals is very good.

The longevity factor "glutathione" can produce glutathione oxidase under the action of selenium, which has the function of delaying aging.

2. Nutritional differences

In terms of color, different colors of corn contain different pigments.

Yellow corn: Carotene and zeaxanthin are good for keeping eyesight and health.

White corn: contains no plant pigment and is not easy to deteriorate.

Purple corn: anthocyanin, so it has antioxidant and anti-aging effects.

Flower corn: contains some anthocyanins. In addition, flower corn is not a genetically modified product, but is selected through long-term evolution through gene mutation, natural hybridization (recombination), artificial hybridization and other ways.

What's the difference between different varieties of corn?

First, it tastes different.

The fundamental reason for the difference between these two kinds of corn is the difference in composition and content. The starch content of waxy corn itself is as high as 70%-80%, and the starch contained in it is basically amylopectin. Therefore, compared with sweet corn, it tastes soft and chewy. Generally speaking, people with bad teeth had better eat this kind of corn. However, the content of starch in sweet corn is very small, and most of the components are sucrose, fructose, glucose and water-soluble polysaccharide. Therefore, compared with waxy corn, it tastes sweeter with thin skin and more juice. It is for this reason that it is called sweet corn.

Second, the nutritional value is slightly different.

Generally speaking, the nutritional value of sweet corn is higher than that of waxy corn. The main reason is that sweet corn is not only rich in sugar, but also contains nutrients such as carotene, riboflavin, lysine, protein, vitamins, minerals, linoleic acid, folic acid and nutritional fiber, which is much more than waxy corn. Therefore, the nutritional value of waxy corn is much lower than that of sweet corn.

Third, the shelf life is different.

Sweet corn can't be preserved for a long time because of its composition. On the other hand, the storage time of waxy corn is much longer than that of sweet corn because starch accounts for the vast majority.

What is the best way to eat corn? Sweet corn is sweet and tender, suitable for cooking. Just add a little water to the pot and cook the whole corn on it. Pay attention to the skin of sweet corn, don't peel it, it not only locks the sweetness, but also the fragrance of leaves. In order not to destroy its nutrition, it is best not to cook it for too long. Waxy corn is more suitable for soup. The soup boiled with waxy corn is not as thick as sweet corn, which will not destroy the original flavor of the soup and maintain the nutrition of corn.

Which is better, sweet corn or waxy corn? I'm sure everyone knows. Compared with waxy corn, sweet corn should be nutritious in nutritional value. As for taste, it depends on personal preference and taste.
