Dig "gold" in the corncob

The corncob, which was originally used only for cooking, is regarded as a treasure in Yucheng, Shandong Province. Walking into the villages and towns of Yucheng, you can see signs to buy corncobs everywhere, 200 yuan per ton for wet corncobs and 400 yuan per ton for dry corncobs.

It is reported that from corncob to finished product processing requires a very complicated process, which mainly includes more than 30 processes, such as hydrolysis, purification, evaporation, crystallization, centrifugation, drying, and so on. Xylitol is a sweetener called xylitol, which can prevent dental caries, does not increase the value of blood sugar, and has a certain role in the regulation of intestinal flora. Corncob can also be processed into another sugar-xylooligosaccharides, which can also regulate intestinal flora and can be added to beverages and health foods. Corncob residue after xylitol extraction can extract ethanol as chemical raw material and fuel; after twice extraction, it can continue to extract lignin to generate electricity or grow mushrooms. The author found that many local farmers grow mushrooms, choosing waste residue as sticks can save 50% of the cost, and the quality of the mushrooms planted is also very good. The circular economy chain of corncob has brought more than 10 billion output value to the people of Yucheng.
