中文摘要:

      乙烯利是一种常见的含有磷酸基团的植物生长调节剂, 主要作用为释放乙烯与促进植物体释放乙烯, 起到使农作物催熟、增产的效果, 由于其经济易得, 在农业生产中被广泛使用。然而生产实践中缺乏科学有效的指导, 存在不合理或过量使用乙烯利的现象, 影响人民群众健康的同时导致环境的污染。乙烯利在植物源性食品上的残留量低, 常需要进行痕量分析。但由于乙烯利物理性质特殊, 极性大、难挥发、无生色基团, 且植物源性食品的种类繁多、基质复杂, 无法并入现有常用农药多残留分析方法, 而目前主流的检测方法步骤烦琐、危险性大, 给分析检测造成了一定的困难。因此, 本文从国内外研究乙烯利残留分析方法入手, 围绕前处理方法及检测方法进行综述, 总结现有分析方法的优缺点, 并阐述其发展趋势, 为研究人员开发简便、经济、可靠的新方法提供参考, 为保障食品质量安全研究提供依据。

英文摘要:

      Ethephon is a common plant growth regulator containing phosphoric acid group. Its main function is to release ethylene and promote the release of ethylene from plants, so as to accelerate the ripening and yield increase of crops. Ethephon is widely used in agricultural production due to its economic availability. However, the lack of scientific and effective guidance in production practice, unreasonable or excessive use of ethephon phenomenon, affect people’s health and lead to environmental pollution. Ethephon residues in plant-derived foods are low and often require trace analysis, but due to the special physical properties of ethephon, such as large polarity, difficult volatilization and no chromogenic groups, and plant-derived food has many kinds and complex matrix, so it cannot be incorporated into the existing methods for multi-residue analysis of pesticides. However, the current mainstream detection methods have complicated steps and high risk, causing certain difficulties for analysis and detection. Therefore, this paper started from domestic and foreign research on ethephon residue analysis methods, reviewed the pretreatment methods and detection methods, summarized the advantages and disadvantages of existing analysis methods, and expounded its development trend, so as to provide a reference for researchers to develop simple, economical and reliable new methods, and provide a basis for food quality and safety research.
