Every year from August to October, it is a period of sadness and joy for families with corn. The joy is the bumper harvest of corn, and the sadness is to start cleaning the corn. Before, there was no special machine for removing corn kernels. The whole family was handmade. After a few days, blood bubbles were all over their hands. The removed corn kernels were made into corn flour, corn oil or stored as food, and then sold at a good price to subsidize the family. The remaining pile of corncob blames drying for firewood. But with the understanding of corncob, it is found that its function is more than that. With the rising price of fertilizer, farmers cast their eyes on corncob.

The main components of corncob are sugar and a lot of crude protein and crude fiber, which is really a good choice for feed. Pigs eat the processed corn cob mixed feed, which is not only delicious, but also easy to gain meat. When it is sprinkled on farmland, it can continue to emit nutrients. In rural areas, many people also use corncob as a Petri dish for edible fungi, put corncob in the shade, and cultivate Pleurotus ostreatus, Lentinus edodes and so on after fermentation and mycelium placement. The value of Xunlei corncob, which is often eaten, has been paid more and more attention in our country. Many glasses, buttons, electronic components, auto parts and so on will use corn cob. Nowadays, people rarely use corncob as a firewood spoon, which is too wasteful. The money earned by hoarding and waiting for others to buy corncob can even be comparable to that of corn kernels, because corncob will go abroad and cross the ocean to Japan, the United States, South Korea and so on. Especially in South Korea, corncob is a hot commodity, which is very different from the new usage of corn in our country.

Korean corn cob appears on the conspicuous shelves of major supermarkets as a delicacy, and one can sell for two pieces. Koreans who love pickles, corncob is like a clear stream, conquering the taste buds of Koreans, and even treating it as a treasure. They have developed a variety of ways to eat corncob. Our country is keen on drinking all kinds of tea. Koreans love to drink water soaked in corncob. They think that corncob has certain medicinal value. Drinking more corncob water can strengthen the body, and even mix corncob with cereal, sugar and honey. It is a favorite drink for men, women and children. It is a common way to eat breakfast in Korea to crush corncob and add rice to cook porridge. In addition, the corncob is sliced as seasoning, and various kinds of soup porridge such as rice cake soup, miso soup and pickled vegetable soup are added, or added to dishes. It is thought that this can give soup a drink, enhance the flavor of dishes, and taste the fresh fragrance of corn. In Korea, many families may not hoard rice, but they will choose to hoard corn, which has become an essential part of their cooking. Why are Koreans so keen on corncob?

Because there are many sisters-in-law in Korea, the arable area is small, so we can't give up planting Chinese cabbage. The amount of other grains planted is very small, and the climate in Korea is very cold, so many vegetables can't be planted, so there are not many kinds of edible grains, and the resources of products are scarce, and they have a special liking for corncob with high nutritional value, storage resistance, simple production and wide use, so they are imported from China in large quantities. China's export price of corn cob is not high, which is a kind of food with good quality and low price for South Korea. Every year, one ton of corn cob is transported to South Korea, and China's export of corn cob alone earns more than 4 billion yuan, which can not only solve the demand of South Korea for eating corn cobs, but also benefit Chinese farmers, which is simply a business with the best of both worlds. After the value of corn cob was developed, the corn thresher also solved the problem of corn foaming.

Nowadays, corncob is also made into xylitol, dietary fiber and other foods. Adding it to paper pulp can also increase the toughness of paper. From this point of view, the new uses of corn will be more and more.
