荧光反射薄层扫描法测定食品中黄曲霉毒素Ｂ_１的技术探讨谭雯茵，陈捷目前国内测定食品中黄曲霉毒素Ｂ１（ＡＦＴＢ１）普遍采用薄层色谱法。此法延用已久，但由于手续繁复，用肉眼观察荧光强度进行测定，易引起系统误差，一般仅限于半定量。使用薄层扫描仪测定ＡＦＴＢ?.. Determination of Aflatoxin B1 in Food by Fluorescence Reflectance Thin Layer Scanning TAN Wen-Yin, CHEN Jie At present, the determination of aflatoxin B1 (AFTB1) in foodstuffs is generally carried out by thin-layer chromatography. This method has been used for a long time, but due to complex procedures, with naked eye fluorescence intensity measurement, easily lead to systematic errors, generally limited to semi-quantitative.
