中文摘要:

      目的 对食品中苏丹红I的检测方法进行探索与研究。方法 参照国标GB/T 19681-2005及欧盟标准方法, 采用wateres 2695高效液相色谱仪对食品中苏丹红I进行测定。结果 平行进样RSD小于2%, 标准曲线时相关系数能达到0.999以上, 平均回收率为90.4%, 最低检出限为0.02 μg/mL。对不同种类食品的前处理方法、标准曲线的制备、液相色谱的条件进行了改进, 并取得了一定的成效。结论 改进后的方法精密度高、准确度好、完全能满足食品中苏丹红I的定性定量分析。

英文摘要:

      Objective To explore and investigate the analytical method of Sudan red I in food. Method According to GB/T 19681-2005 and European standard method, Sudan red I in food was determined using wateres2695 high-performance liquid chromatography (HPLC). Results Parallel sampling RSD was less than 2%, standard curve correlation coefficient reached above 0.999, the average recovery was 90.4%, and the low-est detection limit was 0.02 μg/mL. The pretreatment method for different types of food, standard curve preparation, liquid chromatography condition was improved and certain results were achieved. Conclusion The improved method has high precision, good accuracy, can fully meet the qualitative and quantitative analysis of Sudan I in food.
