Using Modern Biotechnology to Promote the Leap-forward Development of China's Maize Further Processing Industry

China is the world’s second largest corn producer with a total production of 120 million tons. At present, the scale structure of domestic corn deep-processing enterprises is irrational, modern bio-technology resources are relatively scattered and insufficiently integrated, which seriously restricts the development of China's corn deep-processing industry, and does not play a proper role in promoting China's agricultural growth and farmers' income. Experts from Jilin Agricultural University and Changchun Science and Technology Bureau of Jilin Province believe that it is necessary to integrate resources and rely on modern biotechnology to push corn deep processing industry to a new level. This is not only an important issue facing the current corn industry, but also a corn-producing region rural area. The strategic focus of economic development and drive new growth points in regional economic development. The rapid development of the corn processing industry shows significant growth According to statistics, China's corn processing volume so far has reached 12 million tons, accounting for 10% of total corn production, corn deep processing industry showed a clear growth characteristics. First, the regional pattern of the corn processing industry has taken shape. Around the main corn producing areas in China, two corn processing industry intensive belts have formed in the northeast and Huang-Huai-Hai, and the corn processing volume accounts for more than 90% of the national total. The main sales area of ​​corn processing products is in the light-developed regions of southeastern China, forming a production and sales pattern of “Northern Plus South”. Second, the corn processing industry has entered a new period of rapid development of modernization. China's corn processing industry has given full play to its advantages of late-developing countries. It has introduced a large number of advanced equipment and technologies from developed countries. After effective digestion and absorption, the level of equipment and technology has rapidly kept pace with the international advanced level. While the quantity of corn processing industry is expanding at the same time, the quality It has also been rapidly improved and is gradually approaching or exceeding international standards. Third, due to the continuous improvement of comprehensive utilization and deep processing, corn deep processing products and markets are expanding. In addition to such preliminary processed products as corn starch, corn oil and fiber feed, deep processed products such as starch sugar, modified starch, and biochemical feed have also been mass-produced, and further refined products of amino acids, organic acids and chemical alcohols have been further developed. The market for corn processing products has also expanded from food, paper, textile, animal husbandry, and other fields to printing, construction, daily-use chemicals, and petrochemicals. Fourth, the intensification of the competition in the corn processing industry has promoted a major turning point and upgrade in this area. This is reflected in three changes: First, the focus of processed product competition has shifted from the area of ​​primary processed products to the area of ​​deep processed products. Promoting the technological upgrading of the corn processing industry and the transformation of the entire growth mode. Second, the competition between the processing industries has shifted from the relative single market competition, the competition for resources to the competition for resources, and the competition for the high point of biotechnology innovation. The new trend of the processing industry moving northwards and upwards; the third is the change from the competition between the main domestic manufacturers to the international competition. This is due to the growth of a number of large processing industries and the involvement of large domestic and foreign enterprise groups. This shift, of course, is effectively pushing corn processing companies toward large-scale grouping and cross-regional and cross-border business operations. Resources and technical advantages are the driving force for accelerating the development of corn deep processing industry. Experts believe that China is facing a new period of opportunity for the development of corn processing industry. China's main corn producing areas have the advantages of resources and biotechnology to develop the corn processing industry. Unique resources advantages: The three northeastern provinces are located in the famous black belt and gold corn belt. This black soil fertile soil, strong carrying capacity, suitable climate, is the most suitable area for food crops, especially corn. In the entire northeastern corn belt, the average annual corn production in Jilin Province reached 15 million tons, and the highest year in 1998 reached 19.977 million tons, ranking first in the country's total corn production. The average annual corn production in the three northeastern provinces and Inner Mongolia reached 43 million tons, and the highest year reached 50.85 million tons in 1998, accounting for about 38% of the country's total corn production. It is the most corn-producing region in China and the most attractive for the development of corn processing industry. The raw material base. Rapidly growing corn processing industry: In recent years, the northeastern region has successively built a corn processing industry based on feed industry and brewing industry. After nine years of development, Changchun Dacheng Industrial Group has become the largest corn deep processing enterprise in Asia with annual processing of 1.66 million tons of corn and foreign exchange earnings of US$66 million. With a production capacity of 150,000 tons of modified starch, 500,000 tons of starch sugar and 130,000 tons of lysine, Dacheng Group ranks first in the same industry in the country. In addition, since 1999, Dacheng Industrial Group’s output value, profits, taxes, and foreign exchange earnings have increased at an average rate of over 50% per year. With the rapid improvement of deep processing capacity, the value of deep processing and finishing has increased per ton of corn. The level of 4217 yuan, corn raw material 900 yuan / ton, corn appreciation rate of 4.7 times, indicating that the overall level and quality of China's corn processing industry has reached a higher level, will inevitably for the corn processing industry and The development of modern biotechnology provides new impetus. Continually advancing corn processing biotechnology: The intensive processing of corn is accompanied by continuous advancement of technology, especially biotechnology, and the process of corn processing industry development is also a process of constant innovation and application of biotechnology. In Jilin Province, the main corn producing area, corn processing biotechnology is continuously advancing through high-intensity introduction and independent innovation, and its level is also leading in China. Dacheng Industrial Group's biochemical research center has reached world-class standards. It has always been aiming at deep processing of starch and has made a fuss about the cost and product differentiation. The lysine strains they have completed have improved, the production process, and the development of inexpensive raw materials have achieved significant results. Breakthroughs, lysine conversion rate exceeded the advanced level of the same industry in foreign countries. Changchun Chemical has made breakthroughs in the research and pilot test of polylactic acid, a high-end product of organic acids. Jilin Light Industry Design Institute is responsible for a number of key projects of the Ministry of Science and Technology, the Ministry of Commerce, and the Bureau of Foreign Experts, and has made good progress in the development of fuel ethanol for the production of scopoletin, starch sugar, and corn stalks. Jilin Province Petrochemical Institute is mainly responsible for large-scale engineering design projects. It has a leading position in Asia and is authoritative. The design of domestic corn processing and construction projects with a capacity of over 100,000 tons is from the Institute. The College of Life Sciences and Molecular Enzyme Engineering Key Laboratory of Jilin University are also committed to the research of corn processing biotechnology. They have achieved a number of achievements in the development of fructose biotechnology and the use of gene recombination technology to open L-lactic acid and new enzyme preparations. patent.
