食品接触纸中杀菌剂迁移量的测定方法

Determination Method of Migration of Germicides in Food Contact Paper

利用超高效液相色谱-串联质谱,建立了食品接触纸中多菌灵、戊唑醇、丙环唑、环丙唑醇等10种杀菌剂迁移量的测定方法。结果表明,此方法对10种杀菌剂迁移量的水基食品模拟物方法检出限为0.0005~0.025 mg/L,橄榄油方法检出限为0.0004~0.02 mg/kg;平均回收率为71.7%~117.7%,相对标准偏差为0.3%~5.2%。此方法灵敏度高,具有较好的准确性和精密度,对食品接触纸的安全风险监测有一定的意义。

A method was established for determination of migration of ten germicides including carbendazim,tebuconazole,propiconazole,cyproconazole,etc.in food contact paper by Ultra High Performance Liquid Chromatography-Tandem Mass Spectrometry.The results showed that the detection limits of this method were from 0.0005 mg/L to 0.025mg/L for aqueous food simulants and from 0.0004 mg/kg to 0.02 mg/kg for olive oil food simulants.The meant recoveries were from 71.7% to 117.7%,with relative standard deviations from 0.3% to 5.2%,indicating that this method was sensitive and accurate,which could be used to precise for safety risk monitor of food contact paper.
