"Everyone doesn't need to check the authenticity of beef and mutton through the soil method." On July 14, the reporter learned from the Ningxia Food Inspection and Research Institute that the laboratory of the hospital cracked the problem of fake and adulterated beef and mutton and products through the biological code. It effectively solves the problems of difficult detection, identification and supervision of adulteration of beef and mutton products. "Since 2013, we have continuously received complaints from consumers that the beef and mutton in the market are sub-filled and counterfeit. However, due to the lack of practical testing methods in practice at that time, the inspection work could not be carried out normally. "The staff of the institute said. In order to allow consumers to eat real beef and mutton with confidence, the Ningxia Food Inspection and Research Institute gathers the scientific research forces of the whole hospital, consults a large number of relevant research materials, conducts hundreds of experimental comparisons, and determines to use real-time quantitative PCR (Real-time PCR) technology Aligned gene sequences, established a method for detecting adulterated ingredients of chicken, duck, horse, and donkey in beef and mutton products, and implemented the "Real-time fluorescent PCR method for detection of chicken and duck-derived ingredients in food" in 2014 The two local standards for the detection of meat products, "Real-time fluorescent PCR method for the detection of components derived from horses and donkeys in food", filled the gaps in this field of detection. In 2016, the Ningxia Food Inspection and Research Institute declared the Ningxia Hui Autonomous Region key research and development (Science and Technology Huimin) project "Ningxia beef and mutton products in the identification of foreign-derived animal-derived substances identification method", through 231 market sales of more than 5000 samples of beef and mutton Group data verification. In 2017, adulterated ingredients of fox origin and dog origin in beef and mutton products were discovered, and the "Real-time fluorescence PCR method for detection of dog-derived components in meat and meat products" and "Fox in meat and meat products" were formulated and implemented. The original component detection method Real-time fluorescent PCR method "two other local standards for the detection of meat products, making the detection tend to be perfect. In January 2018, the project "Recognition of Identification Methods of Introduced Substances of Exogenous Animal Sources in Ningxia Beef and Mutton Products" was successfully accepted.
