植物源性食品中氨基酸类有机磷除草剂分析方法的研究进展
氨基酸类有机磷除草剂是一类含有磷酸基团且能干扰杂草氨基酸生物合成的除草剂, 主要代表品种有草甘膦、草铵膦、双丙氨膦和草硫膦等, 因其除草谱广且经济易得, 在农业活动中应用广泛, 过量与不合理使用除草剂对环境、食品安全造成一定隐患。该类除草剂残留量低, 极性较大且缺少生色基团, 使得常规分析具有一定挑战性; 另外, 植物源性食品种类繁多, 基质成分复杂, 在食品中残留量低, 根据样品特点和分析要求选择合适的分析方法对提高检测的准确度和灵敏度至关重要。因此, 本文对国内外植物源性食品中氨基酸类有机磷除草剂及其代谢物残留量检测所用的传统和新型样品前处理方法以及检测技术进行综述, 总结并展望现有分析方法的优缺点和发展趋势, 为开发简单、快速、准确的新技术和新方法提供参考, 为食品安全研究提供依据。
Amino acid organophosphorus herbicides are herbicides those contain phosphonic acid group and can influence the biosynthesis of amino acids in weed. The main representative varieties of amino acid organophosphorus herbicides include glyphosate, glyphosate, bialaphos, glyphosate-trimesium and so on. These herbicides are widely used in agricultural activities due to their broad-spectrum weeding capability and economically accessibility. However, excessive and unreasonable utilization of these herbicide cause environment and food safety hazardous. Due to the low residue of the herbicide, possessing high polarity and lacking chromophores in spectrum, it is challenging to determine these herbicides by using conventional analytical methods. Additionally, there are complex matrix components in various plant-derived foods with low residues, thus, for purpose of improving the accuracy and sensitivity, it is very important to select appropriate analysis method based on characteristics of monitored samples and analysis requirements. This article summarized the traditional and novel sample preparation method and detection technologies excessively applied for determination of amino acid organophosphorus herbicide and metabolites residues in plant-derived foods at home and abroad, and prospected the advantages, disadvantages and development trend of analytical methods, so as to provide support for formulating simple, rapid and accurate new technologies and methods for further study on food safety control.
