There are many other names for corn, such as glutinous rice, corncobs, corn, Chinese chestnut, and chestnut rice. Corn has many nutrients, such as vitamins, proteins, trace elements, dietary fiber, etc. It is a food suitable for daily consumption. . Among corn varieties, waxy corn, sweet corn, and old corn are the most common on the market. They are white, purple, and yellow. Which kind of corn has high nutritional value?
Different colors of corn have slightly different health care functions because they contain different types of pigments. Compared with white corn, purple corn has more anthocyanins, which have antioxidant and anti-aging effects. Yellow corn contains carotene and zeaxanthin, which is good for maintaining visual health. Now it is a kind of fruity sweet corn. It has a high sugar content, a low starch content and a sweet taste. It can be directly eaten raw.
Here we look at two kinds of corn: waxy corn and sweet corn
Waxy corn is generally white, and sweet corn and old corn are mostly yellow.
Now we talk about the nutrition and suitability of sweet corn, waxy corn and old corn:
Sweet corn is now a kind of "fruity sweet corn". Its protein and vitamin content is 1-2 times higher than that of normal corn, and its selenium content is 8-10 times higher. It contains 17 kinds of amino acids and 13 species are high. In normal corn, it is easy to digest and absorb. If you do not want to eat raw food, you can cook it. Its total sugar is 33.6%, which is about twice that of ordinary fruits, and it is 30% higher than that of watermelons. Because of sweet corn The sugar content is relatively high, and most of it is sucrose, glucose, which is likely to cause elevated blood sugar, so it is not recommended for people with diabetes.
Waxy corn has a relatively high protein content and is rich in vitamin A, vitamin B1, etc. The amylopectin content is very high and it is not suitable for diabetic patients.
Old corn has high crude fiber content and low soluble sugar content. It is a good choice for people who lose weight and people with diabetes.
The difference between old corn and tender corn
The taste of tender corn is relatively sweeter and softer than that of old corn. The corn in the old corn is fragrant, but the taste is almost the same.
When many people buy corn, hawkers often ask whether they want to use old corn or tender corn. If you say that you want to tender corn, you often take it home and eat it. It is an old corn and it is actually very simple.
The tender corn has uniform grains, green leaves, and soft corn. It is fresh and tender corn. The same batch of corn, try to pick the small grain of corn.
Old corn: It feels like a hard state, its leaves are yellow, and the particles are a bit numb. The same batch of corn, the larger the particles, the older the corn.
TIP: The bald corn is a sign of undernutrition and it is recommended not to purchase it.
How to pick real sweet corn and sticky corn
Since normal corn is also yellow or white, sweet corn and sticky corn cannot be completely distinguished from the color. If the hawker holds a yellowish-colored corn and tells you that this is a sweet corn, holding a white corn, saying that it is sticky corn, you can pay attention.
The real sweet corn is a bright yellowish corn with neat particles and a smooth, flat surface. The regular yellow corn is irregularly arranged and has uneven particles.
The true sticky corn is a white corn with smooth grains and a smooth surface. The regular white corn is irregular and the corn grains are uneven.
TIP: In addition, the market color and purple corn are basically waxy corn. The white and yellow corn grains are mixed, and the taste is determined by the type of particles with more colors. For example, there are obviously more yellow particles and its taste is favored by sweet corn.
Can eat raw fruit corn
Fruit corn is a kind of super-sweet corn suitable for eating raw, which belongs to the new face of the corn market in recent years. It is thin, juicy, and has a sugar content of up to 20%. It is twice that of normal corn and is the first choice for raw and squeezed juices. Both raw and cooked foods are sweet and crisp, like fruits, and are therefore called "fruits." "Maize", raw or squeezed juice is preferred. However, its price is relatively high.
