食品中矮壮素与缩节胺的形成及其检测方法研究进展

植物生长调节剂是一种特殊的含有植物激素活性的农药,能够起到改善农作物质量和控制植物生长的作用,近年来植物生长调节剂的毒性及其残留危害吸引了众多研究人员的关注。其中,矮壮素(CHLM)和缩节胺(MEP)作为常用的2种植物生长调节剂,其使用不当和残留危害所引起的食品安全问题并没有引起足够的重视。最近的研究工作将CHLM和MEP确立为大麦麦芽烘烤过程的副产品,而用于研究的大麦属于生态类型,经验证不含任何植物生长调节剂。由此可知,CHLM和MEP是由食品中的天然成分经过热加工处理后形成的化合物。CHLM和MEP作为新的食品加工污染物已成为食品安全问题的研究热点。对CHLM、MEP在食品中的形成进行了综述,并对其检测技术进行总结,以期为CHLM和MEP的研究提供参考。

Research Progress on the Formation and Detection Methods of Chlormequat and Mepiquat in Food

Plant growth regulators are special pesticides with phytohormonal activity that can be used to improve crop quality and regulate growth.In recent years,the toxicity and residual hazards of plant growth regulators have attracted the attention of many researchers.Chlormequat(CHLM)and mepiquat(MEP)are two plant growth regulators commonly used in agriculture in China.But their toxicity and residual hazards have not received enough attention.Recent research work has established CHLM and MEP as by-products of the barley malt roasting process.The barley used for the study was of the ecological type and had been verified to be free of any quaternary ammonium pesticides.Therefore,CHLM and MEP are compounds formed by thermal processing of natural ingredients in food.As new food processing contaminants,they have become a research hotspot in food safety issues.In this study,the formation of CHLM and MEP in food were reviewed,and their detection methods were summarized,in order to provide reference for the research of CHLM and MEP.
