英文摘要:

      Sulfonamides residues are important animal-derived food safety problems. It is of great significance for human health to detect the sulfonamides residues in food. First of all, the general pretreatment methods and principles of sulfonamides residues detection in food in recent 5 years were condensed. The results showed that the pretreatment methods of sulfonamides in food had obvious common characteristics. The common characteristics embodied in that general formula of sulfonamides detection methods would be possible to be made under the same or similar matrix between the characteristics of food by their principle and procedure of pretreatment operation in sulfonamides, which was helpful to improve the detection efficiency. Different pretreatment methods met different requirements such as high throughput, high sensitivity, and high efficiency, respectively. Additionally, this paper introduced new pretreatment techniques for the detection of sulfonamides, analyzed the feasibility of the new technology combined with the actual situation, and compared the advantages of sensitivity between new technology and the common technology. Finally, the research direction of sulfonamides residues detection technology was discussed.
