摘要
利用胶体金快速定量法对玉米、小麦和稻谷中玉米赤霉烯酮测定的可行性进行了系统的分析和鉴定。结果表明：该方法线性范围宽5-900μg/kg,相关系数r〉0.99,检出限为5μg/kg,定量限为12μg/kg,符合GB/T 2761-2011关于食品中真菌毒素限量的要求。正确度平均值为101.5%,加标回收率为84.7%-107.2%,日内和日间精密度实验的变异系数在1.1%-14.4%,均符合GB/T 27404-2008《实验室质量控制规范食品理化检测》附录F对检测方法准确度和精密度的要求。采用配对t检验,与高效液相色谱法测定结果比较,二者无显著差异。
This test uses an enzyme-based acceptor competing reactions of colloidal gold rapid quantitative method for feasi-bility corn,wheat and rice in the determination of ZEN analyzes and identification systems.The results showed that the method is simple,fast detection speed,low cost and good specificity,rapid quantitative determination of corn,wheat and rice in ZEN and suitable acquisitions in the field of food and primary laboratory widely used.
