《GB/T 8381-2008饲料中黄曲霉毒素B1的测定 半定量薄层色谱法》由TC76(全国饲料工业标准化技术委员会)归口,主管部门为国家标准化管理委员会。
本标准于1987年首次发布,本次为第一次修订。 本标准代替GB/T8381―1987《饲料中黄曲霉毒素B1 的测定方法》。 本标准规定了饲料中黄曲霉毒素B1的两种测定方法,并只能用于半定量测定。 本标准与GB/T8381―1987相比,主要变化如下:
―――在试剂条款中,删除黄曲霉毒素B1 标准溶液制备时仪器校正内容,并增加黄曲霉毒素B1 三氯甲烷标准溶液制备与浓度测定;
―――层析时可选择的展开剂种类由两种增至五种;
―――方法A―――单向薄层色谱法中,增加不同体积的标准溶液和样品溶液的点样点;
―――方法B―――双向薄层色谱法中,减少辅助板的数量,并且点样的分布方式不同;
―――检测中增加薄层扫描仪荧光法;
―――确证试验中增加硫酸推测试验。
Scope
This standard specifies two methods for the determination of aflatoxin B1 in feed, which can only be used for semi-quantitative determination. Method A of this standard is applicable to single feed products such as oilseeds and oilseed meals, peanuts, coconut kernels, linseeds, soybeans, palm kernels, tapioca starch, corn meal, cereals and cereal products, pea flour, potato residues and potato flour . When method A is used to determine the interference of a single feed mentioned above, method B is recommended. Method B in this standard is applicable to compound feeds and single feeds not mentioned above. This method is not applicable to feed containing citrus pomace.
