【摘要】 基于食品中采用免疫亲和层析净化荧光光度法测定黄曲霉毒素含量,建立了免疫亲和层析净化荧光光度法测定鸡饲料中黄曲霉毒素B1、B2、G1、G2含量。该方法的检出限2.0μg/kg,相对标准偏差低于10%,平均回收率85%～90%。更多还原

【Abstract】 A detection method of the total amount of aflatoxins(B1,B2,G1and G2)in chicken feed using immunoaffinity chromatography purification by fluorescence spectrophotometry was developed.The developed method exhibited a detection limit of 2.0μg/kg,the relative standard deviations below 10%and the recoveries of 85%～90%.更多还原
