摘要
黄曲霉毒素是迄今发现的真菌毒素中毒性最强的一类,是公认的I类致癌物,在粮食、坚果、油脂、乳及其制品等多种食品中均有发现。因此,研究出准确、快速、便捷的检测方法对保障食品安全和人类健康具有重要意义。荧光免疫分析法具有灵敏度高、准确性好、检测速度快、操作简单等优势,适合现场高通量快速筛查,近年来被广泛地用于检测食品中的黄曲霉毒素。该文介绍了4类常用的荧光标记物(荧光素、量子点、上转换纳米粒子和稀土离子螯合物),并详细阐述了5种荧光免疫分析法(荧光免疫吸附法、荧光免疫层析法、荧光偏振免疫分析、荧光共振能量转移免疫分析和时间分辨免疫分析)的检测原理,以及上述方法应用于检测食品中黄曲霉毒素的国内外最新研究进展,为今后的研究提供借鉴。
Aflatoxins are the most toxic toxins among all well-known mycotoxins.They are recognized as a Class I carcinogen,and are widely present in grains,nuts,oils,milk and their products.Therefore,developing an accurate,rapid,and efficient detection method is of great significance for ensuring food safety and for human health.Fluorescence immunoassay has advantages of high sensitivity,good accuracy,fast detection,and simple operation.Therefore,it is very suitable for on-site high-throughput rapid screening.In recent years,it has been increasingly used for detecting aflatoxins in foods.In this review,four commonly used tracers(fluorescein,quantum dots,upconverting nanoparticles,and rare earth ion chelates) were introduced.Then,principles of five fluorescence immunoassays(fluorescence-linked immunosorbent assay,fluorescence immunochromatographic assay,fluorescence polarization immunoassay,fluorescence resonance energy transfer immunoassay,and time-resolved fluoroimmunoassay) were reviewed.Besides,the latest research progress on detecting aflatoxins in foods using these methods nationally and internationally were emphasized to provide guidance for future researches.
