摘　　要：以多级孔MOFs材料(macro-microporous ZIF-8,M-ZIF-8)作为吸附剂进行净化,建立高效液相色谱法(HPLC)同时检测肉制品中4种偶氮类合成着色剂(胭脂红、日落黄、柠檬黄、苋菜红)的方法。结果表明:在优化仪器条件下,4种偶氮类合成着色剂线性良好,相关系数大于0.999,定量限(LOQs)为0.3~0.5 mg/kg,回收率为92.0%~105.1%,相对标准偏差为0.5%~2.2%。该方法高效快捷,可以同时检测肉制品中的4种偶氮类合成着色剂,缩短了前处理时间,且可循环使用至少5次,降低分析成本。因此,该方法在肉制品中偶氮类合成着色剂的检测中具有较好的运用前景。A high-performance liquid chromatography(HPLC)method was established for the simultaneous detection of four azo synthetic colorants(carmine,sunset yellow,lemon yellow,amaranth)in meat products,using multi porous MOFs(macro microporous ZIF-8,M-ZIF-8)as adsorbents for purification.The results showed that under optimized instrument conditions,the four azo based synthetic colorants had good linearity,with a correlation coefficient greater than 0.999,a limit of quantification(LOQs)of 0.3-0.5 mg/kg,a recovery rate of 92.0%-105.1%,and a relative standard deviation of 0.5%-2.2%.This method is efficient and fast,capable of simultaneously detecting four types of azo synthetic colorants in meat products,shortening the pre-treatment time,and can be reused at least 5 times,reducing analysis costs.Therefore,this method has good application prospects in the detection of azo synthetic colorants in meat products.
