玉米中黄曲霉毒素B1检测方法最新研究

Recent Research Progress in Detection Methods of Aflatoxin B1 in Corn

玉米及其制品是我国食品行业不可或缺的原料,也是食用动物饲养的主要饲料来源。黄曲霉毒素B1是一种霉变玉米中常见的真菌毒素,具有剧烈的急性毒性,长期食用污染黄曲霉毒素B1的食品可诱发癌变,严重损害了民众的身体健康。本文主要从样品前处理技术和玉米中黄曲霉毒素残留最新检测方法两方面进行阐述,分析了国家标准与近年最新样品前处理技术的优劣,重点探讨了表面增强拉曼散射光谱法、侧流层析快速检测方法、荧光检测方法、表面等离子共振检测方法、高光谱成像方法、免疫分析法和电化学传感器分析法的研究成果与发展趋势,以期为我国玉米中黄曲霉毒素残留监测提供新的技术支持。

Corn and its products areindispensable raw materials for China’s food industry and the main feed sourcefor edible animals. Aflatoxin B1 is a common mycotoxin in moldy corn. It hassevere acute toxicity, and long-term consumption of food contaminated withaflatoxin B1 can induce carcinogenesis, which seriously damages people’shealth. This paper mainly expounds the sample pretreatment technology and thelatest detection method of aflatoxin B1 residue in corn, analyzes theadvantages and disadvantages of the new sample pretreatment technology and therelated pretreatment methods in the national standard, and discusses theresearch results and development trend of the surface enhanced Raman scatteringspectroscopy, lateral flow immunochromatographic assay, fluorescence detectionmethod, surface plasmon resonance assay, hyperspectral imaging assay, immunoassayand electrochemical sensor analysis, which provide new technical support forthe monitoring of aflatoxin B1 residue in corn samples.
