In some areas, people will take sweet corn as industrial raw material and extract a lot of starch for sale. There are many ways to eat sweet corn. Fresh sweet corn can be directly fried, made into soup or made into salad for later consumption.
Difference between waxy corn and sweet corn
1, different flavor
There are obvious differences between waxy corn and sweet corn in taste, because waxy corn has a particularly high starch content, up to 70%~75%, and almost no amylopectin. This kind of corn tastes particularly soft and waxy, especially suitable for people with poor chewing ability, while sweet corn contains a lot of fructose, glucose and sucrose, with a high sugar content and tastes very sweet.
2. Water content
The water content of waxy corn and sweet corn is obviously different. Even fresh waxy corn has low water content, because it contains a lot of starch, while sweet corn does not. The water content of fresh sweet corn is very high, up to 40~50%. It will make people feel juicy when cooking in the future.

Sweet corn can be stored in natural environment for less than 10 days, while waxy corn can be stored for about 20 days. If stored in cold storage, it can be stored for one year or even longer without deterioration.

Both waxy corn and sweet corn are suitable for cooking before eating, but the organization of these two kinds of corn is different. When cooking waxy corn, you need to soak it in clear water for several hours, and then cook it in a pot. When the corn kernels are soft, take them out and steam them in the pot, and then take them out for later use. This kind of waxy corn tastes particularly good, and sweet corn is suitable for cooking with skin, which will make the cooked sweet corn taste particularly good.
Nutritional composition, efficacy and function of corn. Nutritional value of all kinds of corn.
1, sweet corn has high sugar content.
Sweet corn tastes sweeter and smoother than ordinary corn because it contains more water-soluble sugar. The sugar content of ordinary corn is only 4%, ordinary sweet corn can reach 6%, and super sweet corn can double on this basis. This kind of corn is very sweet, so you should pay attention to it.
2. Waxy corn is rich in vitamins.
As far as the most common waxy corn and sweet corn in the market are concerned, waxy corn is mostly white, with a relatively high content of protein, which is rich in nutritional elements such as vitamin A and vitamin B 1. The starch content of waxy corn is as high as 70%~75%, and almost all of them are amylopectin. This starch makes waxy corn sticky and soft to eat. Compared with ordinary hard corn, it tastes softer and is very suitable for people with bad teeth. At the same time, it is precisely because of the high content of amylopectin (a polysaccharide) that it is not suitable for diabetic patients.
3. The crude fiber content of old corn is high.
Old corn is mostly yellow, with high crude fiber content and low soluble sugar content, which is a good choice for dieters and diabetics.
In addition, diabetics can take corn silk to help lower blood sugar. Corn silk tastes sweet and flat, and has no side effects on human body. Corn silk contains a variety of ingredients that are beneficial to human body, among which saponins, flavonoids and chromium are the main effects of lowering blood sugar. Saponins are the main components for lowering blood sugar. Flavonoids also have strong antioxidant capacity and can prevent diabetic complications; Chromium is a component of glucose tolerance factor, which is helpful to strengthen the function of insulin.
Therefore, corn stigma is an important prescription for diabetic patients to lower blood sugar. However, the mechanism of corn stigma has not been thoroughly studied. Corn stigma can not be used as an absolute hypoglycemic substance, but only as an auxiliary hypoglycemic treatment.
4. Fruit corn is easy to absorb and digest.
At present, a sweet corn is popular in the market. Because of its thin skin and juicy texture, it can be eaten raw directly. Like fruit, it is also called "fruit corn". Fruit corn is mostly yellow with low starch content. The content of protein and vitamins is 1~2 times higher than that of common corn, and the content of selenium is 8~ 10 times higher, which is easy for human body to digest and absorb.
However, the sugar content of fruit corn is high, and the total sugar content reaches 33% and 6%, which is about twice as high as that of ordinary fruit. Because sweet corn contains more sucrose and glucose, it is easy to cause blood sugar to rise, so it is not recommended for diabetics to eat.
Purchasing skills of fresh corn
First, look at the leaves: the leaves are light green, no yellow leaves, no dead leaves, straight and fresh; If it is wilting, it means that it has been off for a long time.
Second, look at the fracture: if the fracture is rusty, it is definitely not fresh. If it is black, it can better explain that there is something wrong with this corn.
Third, look at the corn stigma. The bare corn beard is dry; Pull the bracts apart a little, and you can see that the corn silk inside is naturally colored (some are green, some are white), not withered, and relatively fresh.
Fourth, look at the corn kernels: the corn kernels don't collapse, they are full and shiny, and they can overflow with a little pinch of nails. When you get old, it dries up and collapses, and the middle is empty.
