中文摘要:

      农药施用是农业生产中预防作物病虫害的有效措施之一, 但是大量且大规模的农药使用也带来了食品农药残留问题, 进而给人体健康带来安全隐患。明确农药在食品中的空间分布和代谢转移途径对于食品安全具有重大意义。传统的检测分析方法仅仅只能对农药进行定性和定量分析, 无法直接观察到农药在食品中的分布情况。质谱成像技术的出现实现了食品中农药残留的可视化分析, 且具有高灵敏度、高空间分辨率和操作简便等优点, 已经成为农药残留检测方面的重要分析工具。本文整理归纳了近5年国内外质谱成像技术用于食品中农药残留检测的研究进展, 重点概述了质谱成像技术的原理、特点及不同技术类型之间的差异性; 并综述了质谱成像技术在食品农药残留检测(包括不同食品来源及不同农药类型)中的应用研究。最后分析了质谱成像技术在农药残留检测中存在的不足和挑战, 并提出未来展望。本文旨在为质谱成像技术在农药残留检测方面的研究与创新发展提供参考。

英文摘要:

      Pesticide application is one of the effective measures to prevent crop diseases and insect pests in agricultural production. However, large-scale use of pesticides also brings food pesticide residues, which brings safety risks to human health. It is of great significance for food safety to clarify the spatial distribution and metabolic transfer pathway of pesticides in food. Traditional detection and analysis methods can only perform qualitative and quantitative analysis of pesticides, unable to directly observe their distribution in food. The emergence of mass spectrometry imaging technology has enabled visual analysis of pesticide residues in food, with advantages such as high sensitivity, high spatial resolution and ease of operation. It has become an important analytical tool for pesticide residue detection. This paper summarized the research progress of mass spectrometry imaging technology for pesticide residue detection in food over the past 5 years, both domestically and internationally. It focused on outlining the principles, characteristics and differences between various types of mass spectrometry imaging techniques. Additionally, it reviewed the application studies of mass spectrometry imaging technology in detecting pesticide residues in food (including different sources of food and different types of pesticides), finally analyzed the deficiencies and challenges of mass spectrometry imaging technology in pesticide residue detection, and proposed the future prospects. This paper aims to provide a reference for the research and innovation development of mass spectrometry imaging technology in pesticide residue detection.
