As one of the three staple foods in China, corn is the staple food with the highest yield. It is planted in many places all over the country. It can be eaten as fruit corn, coarse grains and corn starch, made into corn steamed bread, and processed into snacks such as popcorn.

Of course, corn can also be processed to extract ethanol gasoline and used as feed.

Every autumn, after the corn harvest, farmers thresh it. At present, mechanical threshing is often used, and the threshed corncob is mostly dried by farmers as firewood, mushroom culture medium or feed.

However, this kind of corn cob discarded by farmers everywhere has become a delicacy in South Korea, and it is sold in almost every supermarket, and its retail price reaches RMB in 2 yuan, which is incredible. We should know that there is only one fruit corn in 3 yuan, so why can worthless corn cob sell so much money?

11, the value of corn cob

As a high-protein crop, corn is also a very important grain in the world. It is a treasure all over the body. In addition to corn kernels, corn stigma can also be soaked in water to taste, which can have the effects of diuresis and heat clearing, and has a remarkable effect on the three high people.

In fact, seemingly insignificant corncob also has very high nutritional value, in which crude protein content accounts for 2-6%, crude fat accounts for 1.5%, and crude fiber accounts for 33.1%.

In addition, it also contains mineral elements such as calcium, iron, magnesium and potassium, which is of great help to promote human metabolism.

In rural areas, corncob is most commonly used in mushroom production. Because of its rich mineral components, it can cultivate fungi such as auricularia auricula, Agrocybe aegerita and Hericium erinaceus.

The sugar content in corncob accounts for 51%, so after hydrolysis, xylitol and maltose can be extracted. The former can play a role in beautifying and lowering blood pressure, which is good for diabetics. It can also be added to chewing gum to avoid tooth decay.

The contents of cellulose and lignin in corncob are also very high, and these components are easy to degrade, which can be made into new environmentally friendly tableware to reduce the damage of plastic products to the environment and human body.

Because of its strong wear resistance and excellent toughness, corncob is also used as one of the raw materials for tire making, thus increasing friction and prolonging tire life.

At the same time, the soles made of corncob are more wear-resistant.

Of course, corncob has a very strong adsorption capacity, so it can adsorb dust, dander and so on, leaving no residue and not hurting clothes, so it is very popular in the market.

Of course, plant ash after burning corncob can also be used as lubricant, which can remove oil stains while lubricating the machine.

corncob can also be used for wine-making. Usually, 25 kilograms of liquor can be brewed from 111 kilograms of corncob, and the degree of liquor can reach 51 degrees.

Of course, corncob can also be used to make paper, and the paper processed with it is more wear-resistant.

12. Become a delicacy in Korea

In China, corncob is most often used for feed processing, but in Korea, it has become a delicacy.

Therefore, many businessmen collect corncob and export it to Korea.

It is reported that the export price of corncob can be 311-1111 yuan/ton, which has created 4 billion foreign exchange earnings for Shandong people so far.

In a Korean supermarket, a pack of five corncob costs 2,111 won, which is RMB 11, and one corncob is 2 yuan.

In China, people never imagined that such a humble corn cob could be sold to 2 yuan.

But in Korea, it is already a very cheap thing, and it is deeply loved by Koreans because of its rich nutrition.

It is difficult to carry out agricultural production on a large scale because of the small size of Korea, and there is a shortage of fresh ingredients. The prices of agricultural and sideline products in supermarkets are very high, for example, watermelons need RMB 151, cabbages need 51 yuan, an apple costs more than RMB 11, and a corn costs RMB 18.

In contrast, corncob is really much cheaper, and it is deeply loved by people at the bottom.

So, what kind of delicacies are corncob made by Koreans?

1. Making tea

Koreans like to drink corncob tea and regard it as a daily essential drink. They will cut the bought corncob into pieces and boil it in water for 31 minutes, so that they can make tea and taste it, which can reduce fire and relieve eye fatigue.

2. Cooking porridge

In some supermarkets, corncobs are processed into granules so that people can buy boiled porridge.

Koreans will mix it with rice and cook it. In their view, corncob porridge can lower cholesterol, beauty and blood pressure.

3. Boiling soup

In China, many people like to cook soup with corn, but in Korea, corncob has also become a must for cooking soup, which can make the soup fragrant and delicious.

4. Barbecue

On the streets of South Korea, roasted corn is also a big food. They will roast corn cob in the stove and add pepper and cumin to enhance the taste, which makes it a delicious food, and many people queue up to buy it.

Maybe it's not delicious in China, but it's rare in Han Min's eyes.

Due to the lack of agriculture in South Korea, corncob is difficult to meet the needs of more than 51 million people in China, so it can only be imported in large quantities from China. Shandong people found this business opportunity, and then started to build factories to process corncob and export it to South Korea, thus creating an output value of 4 billion.
