Progress of Analytical Technologies for Mycotoxin in Foodstuff and Oils

摘要

Mycotoxin is a secondary metabolite produced by fungi species,which now become the most contaminant of foodstuff and can be occurred very widely.Therefore,analytical methods play a great role for monitoring and estimation of the contaminants.Facing so many kinds of current analytical techniques for mycotoxin,we concluded our progress of four different levels of analytical methods as the following,(1) High fidelity method-UPLC-MS/MS,(2) High fidelity method-HPLC-FD,(3) quantitative rapid method (ex portable rapid tester) and (4) qualitative rapid method (ex immunochromatographic strip).%真菌毒素是真菌产生的次生代谢产物,当前已经发展成为粮谷最严重的污染源,其污染分布十分广.因此,检测方法在真菌毒素污染监测和评价中扮演重要角色.我们将当前各种真菌毒素分析技术分成了以下四个层次,(1)超高效液相色谱-多级质谱确证检测方法,(2)高效液相色谱配荧光检测器确证检测方法,(3)快速定量分析方法(如便携式速测仪),(4)快速半定量或定性分析方法(如免疫层析试纸条).首先阐述并比较了每种检测方法的特点,可以帮助分析人员根据具体检测目的选择适宜方法；然后以黄曲霉毒素为例描述了四个层次真菌毒素检测技术研究进展；最后着重强调了真菌毒素检测技术进一步发展面临的主要挑战.我们相信未来的真菌毒素分析方法将趋向于简单化、智能化和便携化,而且为了保护农业环境和农产品及食品质量评价,并保障消费者健康与生命安全,未来分析方法中化学品及毒素标准物质用量也将越来越少.
