What are the corn deep processing products?
Corn oil. Corn oil is one of the deep-processed products of corn, and the high oil content corn cultivated abroad can reach 72%~7.5%, the oil content of corn in China is generally 35% 4% is about 4%, while the high oil content corn cultivated in China can reach 8% 10%. The corn oil produced by the deep processing of corn can be further processed into corn salad oil, which can add value to corn. Corn oil is an edible and health vegetable oil worth promoting, with an unsaturated fatty acid content of more than 85%, mainly oleic acid and linoleic acid, and the absorption of aluminum is more than 97%. It is an excellent functional health food, long-term consumption can not only provide calories for the human body, but also is an essential nutrient for the human body. Sitosterol contained in corn oil can inhibit the increase in cholesterol, alleviate arteriosclerosis, **coronary heart disease, and promote human health. With the increasing importance of people's health, the market demand for corn oil will increase.
Corn meal. Corn meal is a by-product of corn oil production, it is a nutrient with protein as the main component, in line with modern nutrition concepts. Due to the shortage of supply in the domestic market, its economic benefits are high and the prospects are broad.
Corn saccharification. The waste residue after corn saccharification, fermentation and distillation can be dehydrated and dried into flour, or processed into pellets to make DDGS protein feed. In the fermentation process, the corn raw material only consumes starch, and other nutrients are not reduced, but relatively increased, such as increasing protein, so that the amino acid composition is more reasonable. Testing of DDGS products has shown that it contains 18 amino acids needed for animal growth and can also be used as food additives. A large number of experiments and practical applications at home and abroad have shown that DDGS can improve the weight, yield, cost and benefit of cattle, chicken and fish compound feed. However, China's DDGS production is a new industry that has developed in the past decade, and its production capacity is still small. According to the statistics of the industry association, the annual production capacity of DDGS is about 250,000 tons, which has not yet formed a large production capacity, which can not meet the demand of the domestic feed industry for protein feed. In 2001, only 50% of the total demand for protein feed was met, and the market potential is huge.
Water-soluble proteins.
Aqueous proteins extracted from crops such as corn are the essence of protein and superoxide dismutase. It has an anti-aging effect, can be directly absorbed by the human body, and participates in metabolic regulation. It is an indispensable and important ingredient for skin care, beauty cosmetics and health care products. The market demand is large, and the supply exceeds the demand, **year by year**. Superoxide dismutase is in short supply in the world.
What is the importance of corn deep processing?
Optimize the industrial structure: As an important form of agricultural industrialization, corn deep processing can extend the industrial chain and increase the added value of products. At the same time, it is also an important measure to solve the problem of agriculture, rural areas and rural areas.
Promote the development of related industries: The rapid development of corn deep processing industry can drive the development of related industries, such as textile, automobile, food, medicine, materials and other industries.
Improving economic efficiency: Through a comprehensive understanding and in-depth study of the important role of corn industrial processing and its impact, and formulating scientific development countermeasures, it is of great significance to take the initiative to do a good job in macroeconomic regulation and control of grain, maintain the balance between corn supply and demand, and promote the healthy development of China's economy.
