Application In Veterinary Drug Residue Detection
After research, it has been found that the QuEChERS method has more prominent characteristics and can be applied in a variety of applications, including not only fruits and vegetables, but also milk, blood, and meat. In order to obtain more satisfactory test results, the researchers improved and innovated the QuEChERS method on the existing basis, so that the QuEChERS method can be applied to the detection of meat food, and the pesticide residue on the meat food can be detected. If you want to purify meat food, you must remove its fat.
Therefore, relevant personnel should use a reasonable and scientific method to remove fat. In most cases, purifiers and extractants are used to purify meat food, so that the purity of the meat obtained and the accuracy of the test results are higher. This method has the advantages of simplicity, ease of operation, and low cost, so experts must actively use this method to create a safe and healthy food market for people, and apply this method to the detection of more high-fat foods, such as milk, various cooked foods, etc., which can accurately measure and analyze the pesticide residues of these foods to ensure food safety, and also promote the development of the agricultural market economy.
Li Feng and others used the QuEChERS method combined with liquid phase tandem mass spectrometry to detect 12 kinds of sulfonamides, 19 kinds of quinolones, and 8 kinds of benzimidazole drugs and metabolites in chicken liver. Finally, good effects of protein denaturation precipitation centrifugation, matrix water removal, fat and carbohydrate removal, and degreasing are achieved. Wang Zhi et al. improved the QuEChERS method, using 0.5% acetic acid acetonitrile as the extraction solution, PRIME HLB solid phase extraction purification, nitrogen blowing concentration, and reconstitution. Combined with UPLC-MS / MS high-throughput rapid detection of 8 kinds of hormones, 6 kinds of β-receptor agonists, and 4 kinds of antibiotic growth-promoting drugs in bovine liver. The results showed that the recovery rate was satisfactory and the relative deviation was small.
The QuEChERS method has the advantages of convenience, economy, and high accuracy of the test results, so it is widely welcomed in food testing. The traditional food safety detection method has low technical content, insufficient accuracy of the detection results, and limited detection range. The QuEChERS method has a wide range of applications and can detect food, agricultural, and veterinary drug residues in a timely, efficient, and accurate manner.
With the continuous improvement of scientific and technological levels and the efficient research and development of new extractants and catalysts, the QuEChERS method will greatly play a role in the detection of food, agricultural and veterinary drug residues.
