摘要
建立了食品接触材料中16种多环芳烃类化合物溶出暴露的气相色谱质谱联用(GC-MS)分析方法。样品以异辛烷为模拟物,按实际使用情况进行模拟浸泡实验,所得浸泡液用GC-MS进行分析。结果表明,食品接触材料中4种多环芳烃类化合物(萘、菲、荧蒽和芘)存在一定程度的溶出暴露水平,检出率分别为萘24.3%、菲77.1%、荧蒽48.6%、芘44.3%。其中部分食品用容器多环芳烃的溶出水平最高达33545 ng/kg(萘)、46296 ng/kg(菲)、17739 ng/kg(荧蒽)、15594 ng/kg(芘),并发现常规项目蒸发残渣(正己烷)的溶出与多环芳烃的溶出存在一定的正相关关系。萘、菲、荧蒽、芘等四项多环芳烃的方法平均回收率为76.5%~100.7%,相对标准偏差为1.0%~3.5%,本研究方法具有较好的准确度和精密度。
A method was established for the analysis of 16 kinds of the polycyclic aromatic hydrocarbons migration in food contact materials by GC-MS.Basing on the actural conditions of use,the sample was taken isooctane as the migration simulation and immersed,analyzed by GC-MS.As the results,there were 4 kinds of PAHs( naphthalene,phenanthrene,fluoranthene and pyrene) had a certain migration exposure level,in the food contact materials and the positive detection rate was 24.3%( naphthalene),77.1%( phenanthrene),48.6%( fluoranthene),44.3%( pyrene).And migration level of food contact container was up to 33545 ng/kg( phenanthrene),46296 ng/kg( phenanthrene),17739 ng/kg( fluoranthene),15594 ng/kg( pyrene),which was found that there was a positive correlation between the dissolution of evaporative residue( hexane) and the dissolution of polycyclic aromatic hydrocarbons.The four kinds of detected PAHs( naphthalene,phenanthrene,fluoranthene and pyrene) had a average recovery between 76.5% and 100.7%,the RSD between 1.0% and 3.5%,this method showed that a good level of accuracy and precision.
