动物饲料 混合饲料中黄曲霉(毒)素B1含量的测定 高性能液相色谱法

[中文适用范围]： 本标准规定了测定动物饲料（包括含有柑橘果肉的饲料）中黄曲霉毒素 B1 含量的高效液相色谱（HPLC）方法。 测定下限为1μg/kg。 注1：本国际标准可适用于多种原料和直接饲料中黄曲霉毒素B1含量的测定，如玉米朊、花生、棕榈仁、干椰肉、柑橘果肉、木薯粉、大豆、米糠、鳕鱼等。 、油菜籽、尼日尔籽和棉籽（见参考文献[1]和[2]）。 然而，这些材料并未包含在该方法的协作测试中。 注2：本标准也可适用于黄曲霉毒素B1、B2、G1和G2总量的测定。 然而，该方法尚未通过协作测试对该参数进行验证。 [外文原描述]： This International Standard specifies a high-performance liquid chromatographic (HPLC) method for the determination of aflatoxin B1 content of animal feeding stuffs including those containing citrus pulp. The lower limit of determination is 1 mg/kg. NOTE 1 This International Standard may be applicable for the determination of the aflatoxin B1 content of a number of raw materials and straight feeding stuffs such as corn gluten, groundnut, palm kernel, copra, citrus pulp, tapioca, soya bean, rice bran, pollard, rape seed, niger seed and cotton seed (see references [1] and [2]). These materials were, however, not included in the collaborative testing of the method. NOTE 2 This International Standard may also be applicable for the determination of the content of the sum of the aflatoxins B1, B2, G1 and G2. However, the method has not been validated for this parameter by collaborative testing.
