动物饲料.玉米赤霉烯酮含量的定性测定

[中文适用范围]： 本国际标准规定了动物饲料，特别是玉米中玉米赤霉烯酮的定性测定方法。 此方法仅用于筛选目的。 玉米赤霉烯酮的测定限约为50 μg/kg。 注：虽然高粱产生与玉米赤霉烯酮相同的干扰荧光斑点，但该方法仍然适用于这种饲料，因为在第二方向上色谱图展开后，Rf 值不同。 这些斑点不是通过指定的确认技术形成的。 [外文原描述]： This International Standard specifies a qualitative method for the determination of zearalenone in animal feeding stuffs and, in particular, in maize. This method is for screening purposes only. The limit of determination of zearalenone is approximately 50 μg/kg . NOTE Although sorghum gives interfering fluorescent spots identical to those of zearalenone, the method is still applicable to this feed because Rf the values are different after development of the chromatogram in the second direction. These spots are not developed by the specified confirmation technique.
