食品.谷物、坚果和衍生产品中黄曲酶毒素B1、B2、G1和G2总含量的测定.高效液相色谱法

[中文适用范围]： 本国际标准规定了采用免疫亲和柱净化和柱后衍生化的反相高效液相色谱方法，用于测定谷物、坚果及其衍生产品中的黄曲霉毒素。 黄曲霉毒素 B1 以及黄曲霉毒素 B1、B2、G1 和 G2 总和的定量限为 8 μg/kg。 该方法已针对总黄曲霉毒素含量为 24.5 μg/kg 的玉米、含量为 8.4 μg/kg 的花生酱以及含量为 16 μg/kg 的生花生进行了验证。 研究还表明，该方法可用于油籽产品、干果及其衍生产品。 [外文原描述]： ISO 16050:2003 specifies a reverse-phase high-performance liquid chromatographic method, with immunoaffinity column clean-up and post-column derivatization, for the determination of aflatoxins in cereals, nuts and derived products. The limit of quantification for aflatoxin B 1 , and for the sum of aflatoxins B 1 , B 2 , G 1 and G 2 , is 8 micrograms per kilogram. The method has been validated for maize containing 24,5 micrograms per kilogram, for peanut butter containing 8,4 micrograms per kilogram, and for raw peanuts containing 16 micrograms per kilogram of total aflatoxins. It has also been shown that this method can be used for oilseed products, dried fruits and derived products.
