Outline
As an important nutritious food, the quality and safety of eggs, especially the problem of veterinary drug residues, have attracted much attention. This paper systematically reviewed the present situation, core challenges and development trend of detection technology for veterinary drug residues in eggs. First of all, this paper analyzed the current situation of the standard system of veterinary drug residue limit in China, and pointed out the key problem that the detection methods and standards are not matched, which is embodied in the lack of targeted detection methods for 24 kinds of veterinary drugs in egg matrix. Secondly, the latest progress of detection technology is emphasized: In the pretreatment technology, the development of improved QuEChERS method,micro-extraction technology and magnetic solid-phase extraction has significantly improved the purification efficiency and automation level; in instrumental analysis, ion trap mass spectrometry and high-resolution mass spectrometry provide powerful tools for multi-residue high-throughput screening and non-targeted discovery. In terms of rapid detection technology, the integration of nano-materials and traditional detection technology has greatly improved the sensitivity and timeliness of on-site screening. Finally, this paper looked forward to the future development of technology, and the development of microfluidic chip technology, spectral analysis method based on artificial intelligence, portable mass spectrometer suitable for on-site screening and multi-technology combined platform will be the focus of development. In order to provide reference for ensuring the quality and safety of egg products and promote the healthy development of the industry.
