Corn starch can be directly used in food, cooking and industry, and can be used to produce modified starch, starch sugar, amino acids, organic acids, enzyme preparations, antibiotics, polysaccharides, alcohol and other biochemical products. Alcohol can not only be used as fuel ethanol, but also be made into intermediate products such as ethylene, ethyl acetate, butadiene and acetaldehyde through chemical reaction, and further processed to produce fine chemical products.

Ordinary starch cannot be gelatinized and regenerated in cold water, and its viscosity is unstable. However, changing the molecular structure of starch through physical and chemical treatment can change its original properties and give it new functional characteristics to meet different uses, and denatured starch can be formed after denaturation. Mainly used in food, feed, papermaking, textile, medicine, casting, construction, oil drilling, mineral processing, environmental protection and other fields.
