What are the prospects for the development of corn deep processing? What are the development directions?

Corn is not only a common food, but also a very important industrial material. Corn can be processed into more than 3000 kinds of industrial products. So in what direction can corn deep processing develop?

I. the development prospect of deep processing of corn

Corn is the main food crop, which can be used for agricultural planting and marketing, primary food, feed processing and so on. In addition, physical and chemical methods and fermentation engineering are also used for deep processing. Corn deep processing products mainly include corn starch, corn gluten meal, modified starch, corn starch sugar, corn oil, edible alcohol, fuel ethanol, glutamic acid, lysine, polylactic acid, xylitol, chemical alcohol, protein feed, fiber feed and so on. Corn deep processing products are widely used in textile, automobile, food, medicine, materials and other industries. With the deepening of the processing level, the corn economic system is formed.

In recent years, the corn deep processing industry is developing continuously. Corn is one of the most suitable industrial raw materials among the food crops, and it is also the food crop with the highest degree of processing. The corn processing industry is characterized by large processing space, long industrial chain and rich products, including starch, starch sugar, modified starch, alcohol, enzyme preparation, condiment, medicine, chemical industry and so on, but mainly starch and alcohol. most of the other products are deeper processing products or by-products of these two products, which have high value, that is, they have high added value. This will lead to high profits.

Corn deep processing is still a promising industry in the corn industry, and it is also a rapidly growing part of corn consumption, which can be used in many fields, such as food, medicine, chemical industry and so on. The prospect of future development is also very good.

Introduction of Corn Deep processing Industry

Although there are many deep-processed products in the corn processing industry, the most important ones are ethanol, starch, chemical alcohols and other related fields.

1. Corn starch processing industry

The proportion of corn starch in the starch processing industry is increasing. China is rich in starch raw materials. China has the capacity to produce more than 400,000 tons of modified starch, but the actual production is only more than 200,000 tons. in addition, thousands of tons are imported from abroad every year. In recent years, the state has mainly organized a number of industrialization development of corn modified starch technology, realized the localization of key equipment, and gradually solved the situation that there are few varieties of modified starch, low serialization and some products still need to be imported in China. Some products can replace similar foreign products. The demonstration project of corn modified starch processing industrialization has significantly increased the added value of corn production of modified starch products, which is dozens of times of the original value of corn, and has great potential to develop modified starch industry. With the continuous progress and innovation of technology, modified starch is the inevitable trend of starch deep processing.

two。 ethanol

Fuel alcohol produced from corn is cheap and environmentally friendly, and fuel alcohol will never cause adverse reactions to automobile engines, so the market potential is huge. Ethanol will enter the field of petrochemical basic raw materials. The technology of producing ethylene from ethanol has been mature, and it is an excellent basic raw material for daily chemical industry. As a renewable recycling resource, ethanol is not only a new energy, but also can produce ethylene to support the petrochemical industry in the "post-oil era", thus becoming a new basic industry in this century.

3. Corn chemical alcohol

The status of corn chemical alcohol is equivalent to ethylene in petrochemical industry. With corn chemical alcohols, all the products that petrochemical alcohols can produce, such as synthetic fibers, engineering plastics, special resins and polyurethanes, can be derived from almost anything. Corn chemical alcohol and petrochemical alcohol have the same molecular formula, the same use, the only difference is that the raw materials are different.

Corn chemical alcohol is used in textile, the coloring degree is better. With the production and application of corn chemical alcohol, the development space of corn deep processing is broader. To produce 1 ton of chemical alcohol, 8 tons of oil is needed. If corn is used instead of oil, only 1.76 tons of corn is consumed. The cost of producing tons of oil is about 7000 yuan, while the cost of producing tons of corn is about 4200 yuan. The resource and cost advantage of corn industry can be seen from this. Corn chemical alcohol production can improve the scientific and technological content of corn deep processing, and corn chemical alcohol can also be produced for the products that petrochemical alcohol can produce.

Third, the direction of corn processing

Corn is one of the most important food crops, and its nutrition is better than that of rice and potato. But the disadvantages of corn are large grains, low stickiness and poor taste. However, after processing, corn can form a variety of corn food and increase the value of corn.

1. Special corn meal and embryo meal: the fat content of corn grain is high, and it will produce bad taste due to fat oxidation during storage. The oil content of the processed special corn flour is reduced to less than 1%, which can improve the edible quality and the grain size is fine. It is suitable for mixing with wheat flour to make all kinds of pasta. Because it is rich in protein and more vitamins, the added food has high nutritional value and is a good food for children and the elderly.

two。 Puffed food: corn puffed food is a convenience food that has sprung up since the 1970s and is rapidly popular. It has the characteristics of loose and porous, uniform structure and soft texture. It not only has good color, aroma and taste, but also improves the nutritional value and food digestibility.

3. Cornflakes: it is a kind of fast food, which is easy to carry and can be preserved for a long time. It can not only be eaten directly, but also be used to make other foods. It can also be made into convenient foods with different flavors, which can be eaten by brewing with water, milk and soup.

4. Sweet corn: can be used as a vegetable or fresh food, processed products include whole ear quick freeze, grain quick freeze, canned three kinds.

5. Corn beer: because the protein content of corn is close to that of rice, but lower than that of barley, and the content of starch is close to that of rice, but higher than that of barley, it is an ideal raw material for beer production.

Corn is a very important crop, and the nutritional value of corn is also very high. Deep processing of corn can not only preserve the nutrients of corn, but also enhance the value of corn, and the economic benefit is higher. In some areas, there are also subsidies for deep processing of corn.
