Food rapid detector is expected to achieve standardization

As one of the important events in the world food safety exchange, on the 8th of April 2014, BSFDT 2014 Beijing International Food Testing and Retrospective Conference will be listed as one of the important themes in the Beijing International Exhibition Center (Old Building) BSFDT2014. Many domestic and foreign academic organizations and technology manufacturers rely on the rapidly growing Asia-Pacific food market to focus on the world's most advanced rapid food testing technology. Contents include rapid food safety testing, rapid pesticide residue testing, food quality testing, edible oil analysis, food formaldehyde detection, dairy analysis, beverage analysis, water activity analysis, oil oxidation stability analysis, fiber determination, food volume determination, protein fast There are dozens of categories such as assays, tissue analysis, and cream centrifuges. It covers the whole industry chain of planting and breeding, procurement, production, logistics, and even terminals for food production materials.

The rapid growth of the testing market not only promoted the rapid development of domestic testing institutions, but also attracted foreign testing agencies to invest in China to establish laboratories. The broad market prospects in the field of rapid food safety detection have attracted a large amount of capital to enter this industry, which has a certain positive significance for the rapid development of the industry and technological progress. However, various equipment manufacturers should dig deeper into market segments based on their own advantages to better provide products in advantageous areas to meet the multi-faceted market demand.

The rapid detection of food industry development is mixed

Along with the rapid growth in the demand for rapid food safety testing, the rapid food testing equipment industry has also seen mixed growth. Because there are many manufacturers of fast-check products, the accuracy of fast-checking of their products is also different. Zhang Hongyan, deputy chief of the department of urban and rural warehousing supermarkets in Haidian District of Beijing, believes that the accuracy rate of most regular quick-check products on the market is about 70%. Because there are many manufacturers of fast-check products, the accuracy of fast-checking products varies from product to product. In the actual operation of the quick inspection product, there will be false positives, that is, the quick inspection has detected problems, but after further tests conducted by a state-qualified laboratory, there is no problem; there are also false negative cases, that is, there is no problem in quick inspection. However, after further tests conducted by nationally qualified laboratories have identified problems, these situations can sometimes cause food problems to escape the net and sometimes cause miscarriage of justice.

At present, relevant departments of the State are brewing mechanisms for the entry and product certification of manufacturers of fast-check products. Actual testing is performed on accuracy, detection limit, precision, repeatability, reproducibility, anti-interference, and analysis time of the entire process. This is to evaluate the effectiveness of rapid inspection equipment, improve product production and sales thresholds, ensure healthy development of the industry, and truly play the role of fast inspection as a primary guarantee of food safety technology.

Fast detection instruments tend to be portable and informatized

More than a decade ago, the funds for rapid testing of projects were very few. Now that the funding for rapid inspection projects has been increased, the government is paying great attention to the rapid detection technology research. From Beijing Zhongwei in the 1990s to Wanger after 2000, to now Weideweikang, Qinbang Biology, and Sino-German Biology, China’s professional team for rapid detection and R&D has become increasingly large, and the rapid detection technology has developed rapidly. Fast, the technology level of the domestically-made rapid testing instruments and kits has been greatly improved, and the types are increasing. I think that the current domestic rapid inspection equipment is not inferior to the imported rapid inspection equipment and can fully meet domestic demand.

At present, we have put some new technologies into practical use, but there are still some new technologies that are still in our laboratory research stage. In the future, we will gradually realize the commercialization of the instruments so that we can more widely promote applications and meet more market demands.

Gao Zhixian believes that more portable, serialized, informatized, and integrated are the development direction of rapid detection instruments. It is more portable and can even be packed into pockets and brought to the scene to carry out risk monitoring. In series, such as protection against emergencies and large-scale activities, daily supervision and monitoring, we can give a series of coping solutions; information is very important. After the on-site inspection, the data will be directly transmitted to the laboratory for confirmation. This will have a more rapid and more accurate significance for the next step. The future rapid detection instruments will become more and more integrated, such as with molecular imprinting technology, nano-biotechnology, With the combination of new materials and technologies such as biosensing technology, there will be more room for rapid detection.

Rapid inspection of food safety has entered the law

Li Yujia, deputy director of the China Food and Drug Administration, also said that "rapid testing is legally statutory," and the relevant laws and regulations, including the Food Safety Law, stipulate the food safety supervision departments, especially the grass-roots regulatory agencies, and food safety. In the daily supervision process, rapid detection methods should be used to promptly identify problems. "This is clear and the law is stipulated." At the same time, he also mentioned that according to the results of rapid test results, penalties for relevant units and individuals need to be further defined by laws.

Yu Jun, director of the three divisions of the State Food and Drug Administration, said at the meeting: "At present, domestic rapid detection products are widely used in government departments." "But there is no department or related policy to regulate the rapid detection of product quality."

In this case, Yin Jianjun, the secretary general of the National Standardization Technical Committee for Quality Supervision and Inspection of Key Products, said that “the “professional working group for the food safety and rapid inspection method of the National Standardization Technical Committee for Testing Methods for Quality Control Key Products” will be established.” “The main work content is” "The establishment of rapid verification methods for food safety compared with verification standards", according to which "screening rapid detection methods at home and abroad," "a good way to" form a "quick detection standards."
