In recent years, China's food safety incidents have occurred frequently and frequently, which not only has an impact on industrial development, but also poses a threat to the health and safety of the people. It has become a key livelihood issue for the society. Chromatographic analysis instruments - gas chromatography, liquid chromatography, etc., are one of the main means of food analysis, and are widely used in the analysis of food ingredients, toxic and hazardous substances, heavy metals and other items. Recently, I interviewed Yang Yongtan, a vice chairman and secretary general of the Food Safety Branch of the China Instrument and Control Society, on the current status of China's food safety and the development potential of chromatographic instruments in the food industry. Food industry: opportunities and challenges coexist Regarding the current form of food safety in China, Yang Yongtan talks about implementation measures from the guiding policy to the serious problems facing food safety. At present, the Chinese government attaches great importance to food safety. It has repeatedly emphasized from different aspects that it is necessary to use the "four most stringent" measures to effectively strengthen food safety supervision, and to improve the most stringent regulatory system covering the entire process from farmland to table. Agricultural products and food safety. "On May 4th, the Ministry of Science and Technology just released the "13th Five-Year Food Safety Special Project Application Guidelines for Exposure Drafts". These food safety projects will be implemented this year. For future food safety guarantees, confidence in food safety will be enhanced. Has a major impact." Yang Yongtan said. Although China has strongly supported the issue of food safety regulation at the government level, there are still some challenges. Yang Yongtan said, "Due to historical reasons, China's food source pollution is serious, the process control ability is weak, and the lack of supervision and support capacity has not been completely solved. The identification and toxicity mechanism of food safety hazards and the migration and transformation of hazardous materials in food raw materials are carried out. And the safety control mechanism needs to be further studied; in the food production, storage, logistics and other links need to strengthen the process control, inspection and testing, monitoring and evaluation, supervision and emergency technical research, food safety rapid detection reagents and equipment localization rate research is very critical Therefore, food safety issues have both opportunities and challenges for food safety workers. Industry trends: domestic chromatography instruments will play a greater role in food safety In the analysis industry, almost everyone knows that pesticide residues, veterinary drug residues, food additives, mycotoxins, benzopyrene and polycyclic aromatic hydrocarbons, plasticizer additives, trans fatty acids and other toxic and harmful substances are frequently concerned. They are all solved by gas chromatography, liquid chromatography or chromatography-mass spectrometry; some nutrients such as fatty acids, triglycerides, vitamins (including water-soluble and fat-soluble), and sugars are also analyzed by chromatography or Chromatography-mass spectrometry is used as an analytical tool. “We have learned that some of the governing units (including universities, research institutes, central enterprises) and some other third-party testing professional organizations have configured a large number of chromatographic instruments (or chromatographic-mass spectrometers) for their testing projects and tasks. The related instrument companies have also invested a lot of manpower and financial resources. While promoting the instruments, they have developed new testing technologies based on customer needs, and formed a complete set of application solutions, which also improved the technical level of food safety guarantee. But relatively speaking, The food industry is a relatively low-margin industry, and it is difficult for grassroots food companies to allocate expensive foreign chromatographic instruments." Yang Yongtan said. How to adapt the chromatographic technology to the "low profit" of the food industry, Yang Yongtan said: "In recent years, with the country's generous investment in scientific instruments, the gap between the technical level of domestic chromatographic instruments and foreign instruments is constantly narrowing. And because of its certain price advantage, it will play a greater role in the safety and security of the food industry." Learn the role: a bridge between vendors and users Yang Yongtan is the vice chairman and secretary general of the Food Safety Branch of the China Instrument and Control Society. He is also the deputy chief engineer of the COFCO Nutrition and Health Research Institute of COFCO. He shared the Lanzhou 21st National Chromatography Academic Conference and Instrument Exhibition Conference. The report titled “Application of Chromatography in Safeguarding Grain, Oil and Food Safetyâ€. According to the report, based on the quality and safety risk monitoring needs of COFCO's major industrial chains, the Yang Yongtan team systematically researched and developed typical agricultural products for the technical problems faced in the detection of agricultural and veterinary drug residues, food additives, mycotoxins and plasticizers in the food safety field. And high-quality sample pretreatment methods such as agricultural veterinary drug residues, mycotoxins, plasticizers, benzopyrene, high-throughput pesticide residue screening technology and veterinary drug residue immunization rapid test products, and cooperated with Shandong Luchuang Instrument on chromatographic instruments. The technical system of food safety testing indicators such as agricultural and veterinary drug residues, mycotoxins, benzopyrene and plasticizers of COFCO Group was constructed and demonstrated and promoted in the relevant business units of the Group, providing technical support for the quality and safety of the Group's products. At the same time, as a frontline practitioner in the industry, serving the food safety industry is mainly reflected in the development of analytical technology methods, technology applications, etc., and as a member of the Food Safety Testing Instrument and Technology Application Branch of the China Instrument and Control Society, it is committed to creating the club. A bridge between the chromatographer manufacturers in food safety and those engaged in food safety testing, and also plays a communication role in the promotion and application of domestic chromatographic instruments in the grain, oil and food industry.
