has developed and constructed key technologies for safety control and quality improvement of milk and milk products. A basic database of milk product quality, safety and nutritional quality has been constructed to reveal the harm mechanism of mycotoxin coexistence, and an authoritative platform for risk data exchange has been established. Since 2015, relying on the database to submit 205 reports to the competent authorities, the government regulatory authorities have implemented active and efficient supervision based on the types and dynamic changes of the main risk factors in milk and dairy products. Since 2016, the Ministry of Agriculture and Rural Affairs has continuously released the”China Dairy Industry Quality Report” and”China Dairy Product Quality and Safety Research Report” to the public every year based on database data to objectively convey the quality and safety status of the dairy industry and respond to social concerns and strengthen risks. Communication and boosting consumer confidence are of great significance. Developed synchronous detection technology for main risk factors in milk and milk products, developed detection standards for prohibited additives, and formulated technical specifications for safety control in the production process. Synchronous detection technology saves more than 80%of time and more than 60%of costs. It solves the problems of low efficiency and high cost of milk and dairy products testing in the laboratory. It has become a national fresh milk quality and safety monitoring plan and a major national dairy product risk assessment project The method of specifying. Formulated the first international identification standard for reconstituted milk, developed a quality evaluation method for milk and dairy products, integrated quality improvement technology, and developed high-quality pasteurized milk with the lactoferrin and β-lactoglobulin content of imported pasteurized milk. 8 times and 10 times that of sterilized milk, significantly enhance the core competitiveness of demonstration enterprises, and lead the domestic dairy industry to upgrade from safety to high quality. This achievement won the first prize of”2018-2019 Shennong China Agricultural Science and Technology Award”.
has established key technologies for quality improvement and green and low-carbon processes for high-quality milk production. Successfully constructed the”Milk and Milk Product Quality Safety and Nutritional Quality Evaluation Database” and developed my country’s first raw milk grading technology, which solves the problem of the mixed use of milk sources regardless of grade, resulting in a large amount of waste of high-quality milk sources, and major industries where high-quality milk is difficult to price. problem. Develop and create high-quality milk green and low-carbon processing technology, realize the integration of high-quality milk source and high-quality processing technology, lead the dairy industry to upgrade from a quantitative dairy industry to a high-quality green dairy industry, and significantly enhance the core competitiveness of domestic milk. The research and development and establishment of high-quality milk product quality evaluation technology reveals that the difference between domestic milk and imported milk lies in heat damage, and for the first time the scientific concept of “high-quality milk produced from local milk” has become a breakthrough in the structural reform of the supply side of the dairy industry. The green low-carbon processing reduces the processing temperature of pasteurized milk from 95°C to 75°C, increases the content of active substances such as lactoferrin by more than 50%, reduces processing costs by more than 15%, and significantly reduces the amount of water vapor cleaning agent; The standardized technology system for milk production has been demonstrated and applied in more than 50 dairy companies in 25 provinces across the country. This achievement won the”2018 Great Wall Food Safety Science and Technology Award Special Award”.
has carried out the integration, promotion and application of dairy cattle raising technology. Established a”dairy cow raising technology system for improving quality and efficiency”, integrating high-quality whole-plant corn silage production technology that integrates processing and modulation, quality evaluation and efficient utilization, to relieve heat stress and improve perinatal dairy cow health as the core nutrition Regulating technology, the precision feeding technology of total mixed ration based on milk test formula, created the agricultural industry standard of”Technical Specification for Production of Complete Mixed Diet for Dairy Cows”, which promoted the quality and efficiency of dairy cattle breeding. The establishment of an”inverted pyramid” multi-support technology promotion model has played an important role in promoting the high-quality development of the Beijing-Tianjin-Hebei dairy industry.
