Modern analytical instruments are constantly updated, so that there is no hiding of food harmful substances

the development of today's chemical industry and food industry makes the additives in food more and more complex, which puts forward a great problem for food safety inspection, and the development of analytical chemistry provides an accurate and reliable analysis method for food safety inspection. The qualitative and quantitative analysis of various additives and pollutants in food through precise analytical instruments can well avoid food safety risks. Modern analytical instruments have become another guarantee of food safety

the construction of food safety risk monitoring system protects the safety of the tip of the tongue

recently, the food safety risk monitoring system established by the Beijing CDC has attracted the attention of many people in the industry. It is understood that Beijing has initially established a food safety risk monitoring system integrating the whole process of "farmland table hospital", and collected monitoring data on food pollutants and harmful factors at more than 870 sampling points in the city, guarding the "safety on the tip of the tongue" of citizens. From flour and rice to fruits, vegetables and meat, almost all foods that citizens can touch in their lives can be tested in the food testing laboratory here

food safety not only refers to the safety of food directly consumed by human beings, but also includes the safety of these food raw materials, such as animal feed, animal and plant health, etc. In the process from raw material production to final consumption, all links of information need to be complete and sufficient, and the two instruments in the food safety risk monitoring system are particularly important. One of them is pulsed field gel electrophoresis, which can trace the pathogens causing food poisoning. The theme of the conference is the theoretical and experimental analysis of the interaction of friction, wear and fatigue, and the source of results. Another matrix assisted laser desorption ionization time-of-flight mass spectrometer can detect bacterial species within twoorthree minutes under the condition of obtaining pure bacterial cultures, analyze and compare them with the characteristic peak maps of 600 microbial samples in the database, and determine the "culprit" of food disease. It is understood that the current food safety monitoring system has covered 16 districts, with a total of more than 870 sampling points, all located in representative consumer places

the development of food safety standards and the continuous innovation of testing instruments

due to the frequent occurrence of food safety crises, food safety issues have become a hot topic after dinner, and the strict tstdat database data table has reached the level of "talking about food color change". In order to solve the food safety problems that people are most concerned about, the Chinese government has accelerated the construction of food and agricultural product quality and safety standards, inspection and testing, certification and traceability system. In this situation, in order to make food hazards invisible and create a reassuring and reassuring food market for consumers, the field of instrument analysis continues to innovate, and instrument and equipment manufacturers also continue to update food safety detection technology to ensure food safety production

the detection indicators of food safety instruments mainly include the analysis of general components of food, trace elements, pesticide residues, veterinary drug residues, mycotoxins, food additives and other harmful substances. According to the characteristics of the inspected items, the inspection of each index corresponds to the corresponding inspection method. Such as electrochemical method, atomic absorption spectrometry, gas chromatography, high performance liquid chromatography, etc

in the general environment, the rapid development of modern analytical instruments has also promoted scientists to make major breakthroughs in the field of food safety, such as toxicology research, residue analysis research, ultra trace residue precise quantitative analysis, degradation mechanism and so on. In recent years, analytical instruments used in food safety testing have made rapid progress. New analytical instruments are introduced every year, and new analytical methods and techniques are applied. Food importing and consuming countries also continue to formulate and update the maximum residue limits in food to maximize the safety and development of the food industry chain

combined analysis technology helps the development of on-site food testing

food safety inspection and testing technology is constantly developing, and the upgrading of instruments and equipment is also urgent. Its development direction is also different according to the different substances analyzed. With the development of modern scientific instruments, large-scale analytical instruments are more and more widely used, such as organic mass spectrometer, inorganic mass spectrometer and X-ray fluorescence spectrometer. Among them, X-ray fluorescence spectrometry is a non-destructive analysis method and has been developed rapidly

in the use of large-scale analytical instruments, the combined technology of analytical methods has also made great progress. Such as gas chromatography atomic absorption spectrometry, gas chromatography mass spectrometry, etc. The adoption of these combined techniques is faster and more efficient, and completes the inspection effect that can not be achieved by a single analysis method in the past. In addition, based on the fact that spectrophotometry will affect the service life of the device, researchers have developed a pesticide residue detector, which can be used in the field detection of pesticide residues in vegetables in the production, circulation, market and other links. The total weight of the instrument and all auxiliary equipment is only a few kilograms, which is very convenient to carry out, and can be operated indoors and outdoors anytime, anywhere

in terms of the current situation, food safety has never faded out of people's vision, and the future development prospect of the food testing market is still immeasurable. How to sail far with the help of the national reform is still a problem that needs to be pondered in the field of food testing. In general, the problems of the development of food safety rapid testing products are being solved one by one, and the food safety rapid testing market will continue to show vitality
