With the increasing improvement of people's living standards, more and more attention is paid to the quality of life. Whether the food eaten is safe and healthy has become the focus of discussion after dinner. But are the meat products currently on the market healthy? It is undeniable that the current problem of excessive veterinary drugs in animal meat products is still very serious, and a large number of veterinary drugs residues in meat products pose a huge threat to people's health. Therefore, to better monitor the residues of veterinary drugs in meat products, it becomes more and more important to take effective measures to control and reduce the residues of veterinary external medicine. So, what is veterinary drugs monitoring and residue analysis technology discussion? Let's take a look.
Here is the table of contents:
l Rapid detection method
l Instrument detection method
The rapid detection method of veterinary drugs residues is mainly based on the detection method constructed by immunoassay technology. This method can quickly screen samples in large quantities and detect the residues of veterinary tablets. The rapid detection method is not only fast and convenient to apply, but also can analyze and detect a large number of samples at one time, and the cost investment is relatively low. The most commonly cited methods are the colloidal gold immunoassay and method. In the process of monitoring veterinary drugs residues, colloidal gold immunoassay is very simple to operate and can easily determine the monitoring results. The monitoring work does not have high professional requirements for the staff, which can greatly improve the speed of sample detection. The specific method is to adsorb the colloidal gold-labeled reagent on the binding pad. Affected by capillary action, the sample solution can quickly pass through the paper strip, and then the results are observed by visual means. The method has strong specificity and a high degree of automation, as well as good stability. However, there are also some limitations in the application of this method. For example, in the immunoassay work, if there is cross-reaction, it will easily affect the sensitivity and reliability of the detection, and have a great impact on the detection effect of veterinary powder residues. The principle of the method is that the antibody and antigen recognition reaction generated by the sensitive layer of the sensor and the specific target analyte present in the complex sample cause physical and chemical changes.
The first is chromatography. The principle of this method mainly refers to the distribution difference of various substances in the stationary phase and the mobile phase. If various substances are successively transported to one end of the stationary phase, the veterinary powder will be gradually separated due to the difference in movement time.
Second, chromatography-mass spectrometry. This technology effectively combines the advantages of chromatography and mass spectrometry. The separation effect is very obvious, and it has high sensitivity. It can accurately qualitatively and quantitatively analyze the residual analysis of veterinary tablets in the video and is widely used.
Third, capillary electrophoresis technology. This technology is also called the capillary separation method. In the process of analysis and monitoring, the capillary is mainly used as a separation channel, and the driving force is a high-voltage direct current electric field. An important liquid phase technique for the separation of veterinary tablets.
The above is related to the discussion of veterinary drugs monitoring and residue analysis technology.
