China's enzyme preparation industry continues to grow rapidly.

Sponsored by the Enzymes Branch of the China Biofermentation Industry Association, the Enzymes Branch of the China Food Science and Technology Association, the School of Food Science and Nutritional Engineering of the Agricultural University of China, and co-organized by Jiangsu Yiming Biological Co., Ltd., the 5th National Symposium on Enzymes Research and Development Application Technology was held on September 13 at the Agricultural University of China.
Shi Weichen, chairman of the China Biofermentation Industry Association, said in his speech: "The development of China's enzyme preparation industry has mixed feelings, and the next few years will be a critical period for the healthy and stable development of the enzyme preparation industry."
seize the opportunity, accurately grasp the market orientation, adjust the development strategy in a timely manner, and promote technological progress and industrial upgrading in related industries.
" China's enzyme preparation industry continued to grow rapidly Professor Zhang Jianhua, Vice President of China Agricultural University, said in his speech that in recent years, China's enzyme preparation development is rapid, more varieties, more and more application technology more and more in-depth.
With the deepening of enzyme products and expanding applications, china's enzyme preparations to high-grade, high-activity, multi-species direction of development, so that China's enzymes formed an independent industry, in the development of the national economy has occupied an important position.
Food industry is the most important industry for the application of enzymes, widely used in fruit and vegetable processing, baking, meat and dairy processing and other fields, enzymes are China's 12 trillion yuan output value of the food industry is an important driving force for the development.
Shi Weichen said that in recent years, China's enzyme industry has maintained a sustained and rapid growth trend.
, China's enzyme production in 2015 was about 1.2 million tons, an increase of about 4.3% year-on-year.
products, domestic enzyme enterprises mainly produce varieties of glycase, phytase, amylase, fungal amylase, protease, cellulase, glycosyme, etc. ;
, the compound enzyme products represented by feed compound enzyme, beer compound enzyme, etc. have been developed rapidly.
the trend of extending the production of end products based on key enzymes has been further expanded.
domestic market share of domestic enzyme preparation products has increased significantly, reaching nearly 30%.
compared with 2014, imports of enzyme products continued to show growth in 2015, by 9.5% and imports by 4.0%, while exports increased by 3.9% and exports by 5.8%.
Shi Weichen said, with the expansion of enterprise scale and the application of new production technologies and processes, the quality of enzyme products in China has been greatly improved, in new products and new applications in the development, patent technology applications, follow-up technology reserves, etc., enzyme preparation enterprises have invested more funds and energy.
Technological innovation lays the foundation for the enzyme preparation industry The experts held in-depth exchanges and discussions on new technologies, new processes and new equipment for the production of enzyme preparations around the development trends of enzymes, basic research of enzymes, applied research and industrialization at home and abroad.
Professor Lu Fuping, Vice President of Tianjin University of Science and Technology, said in a report entitled "Research and Development of Alkaline Protease" that since the 1950s, the application of alkaline protease has been uninterrupted and has been widely used in washing, food processing, medicine and other industries.
but alkaline proteases need to be further strengthened in key technology applications in the food industry.
First, the characteristics of strong hydrolyzing capacity of alkaline proteases are used to develop compound enzyme preparations suitable for different food processing processes, and to improve the efficiency and characteristics of different food processes; In the screening of complex enzymes and the preparation of target functional peptides, the third is to continuously expand the application of proteases in food functional peptide preparation, including the preparation of protein peptides for different sources and the application of enzyme-dissolving conjunctivation membrane technology in the preparation of specific molecular weight peptides.
Professor Zhang Guocheng, Dean of the School of Bioengineering of Jiangnan University, introduced in the report "The study of enzyme conversion L-amino acid synthesis alpha-ketoic acid" that ketoic acid is widely used in the food and health industries, such as adding alpha-ketoic acid to the food of patients with poor liver and kidney function to replace the corresponding amino acids, which can reduce the liver and kidney burden of patients.
addition, alpha-ketoic acid can also improve the flavor and taste of food.
with advances in technology, L-amino acids are improved in the efficiency of the conversion of synthetic alpha-ketonic acids by enzyme method.
Zhengqiang, Vice Dean of the School of Food Science and Nutritional Engineering, Agricultural University of China, introduced the progress of "Ganlu polysaccharase and its application in the preparation of lulu oligosaccharine".
applications of glycerides in the food industry include: increasing the rate of coffee leaching, softening fruits and vegetables with other enzymes to speed up juice clarification, and preparing glycerol (MOS) and soluble dietary fiber.
research shows that gum and soluble dietary fiber as an important probiotic, its main functions include: to promote the proliferation of probiotics in the intestine, inhibit the growth of harmful microorganisms, but also have a certain effect on lowering blood pressure, blood sugar, blood lipids and so on.
So far, researchers have developed three high-performance glyceride enzymes and efficient production, using these three glycosin enzyme hydrolyzed taro powder, guar bean gum, etc., can efficiently prepare functional licoride and soluble dietary fiber.
Shi Weichen said that at present, China's enzyme enterprises pay more attention to innovation investment, the top 5 enterprises have their own research and development team and research and development laboratory.
industry has the state-recognized enterprise technology center, academician workstation, central local co-construction engineering research center, technological innovation so that domestic enterprises have their own technology reserves, with independent intellectual property rights of invention patents, for the sustainable development of the enzyme industry has laid a solid scientific and technological foundation.
Industry, science and research cooperation to achieve the upgrading of the enzyme preparation industry Shi Weichen stressed that in the industry progress at the same time must also see the development of the problem is more prominent, wherein the technical level of the problem is mainly reflected in the following aspects: First, the problem of a single variety is still more prominent, homogenization is serious, the lack of new high-end enzyme varieties, resulting in unfair competition between enterprises, the overall interests of the industry is damaged.
is that the development of complex enzymes lags behind.
compound enzyme is an important direction for future development, and its added value is higher.
the development of compound enzymes must have strong application research based on, and most of the domestic enzyme enterprises in this regard still lack of technical strength.
is the lack of refined enzymes.
Due to China's extraction and post-preparation technology, technology and equipment level is relatively backward, enzyme products are still mainly crude enzymes, lack of refined enzymes, dosage forms are relatively single, so that its application is greatly limited.
experts at the meeting said that in order to realize the sustainable development of the enzyme preparation industry under the new situation, we must strengthen the industrialization ability of new enzyme species, broaden the application field of enzymes, so that laboratory technology can really go to market and achieve industry upgrading.
Jiang Zhengqiang believes that the series of products, such as oligosaccharides and water-soluble dietary fiber, with ganlu as the main chain, have many functions and will play an important role in the large health industry.
Professor Lu Fuping believes that through the screening and transformation of enzyme molecules, the construction of efficient expression system, large-scale production and enzyme engineering application technology, will break through the bottleneck of high-performance, low-cost, high-quality industrial enzyme production, and help to achieve the leapfrog development of industrial enzymes.
At present, China's enzyme industry development into the adjustment, integration stage, on the one hand, the original part of the enzyme production capacity is not or transfer production, or close, on the other hand, the rapid development of key enterprises, the first group and the enterprise behind the distance is getting bigger and bigger.
" the above-mentioned problems can not be separated from the close cooperation between industry, science and research.
, " said Shi Weichen.
