摘　　要：目的 对一次性纸质食品包装制品(盒、袋、桶、杯等)中挥发性饱和烃矿物油(MOSH)组分的含有情况进行检测分析,以确定纸质食品包装材料及制品中各挥发性MOSH组分向外挥发的性能以及对所包装食品(食品模拟物)的潜在危害性。方法 将样品裁切(5 mm×5 mm)后,取适量样品采用固相微萃取法进行萃取富集,然后使用顶空气相色谱-质谱进行检测,通过NIST质谱库检索、特征离子碎片检索以及标准样品比较相结合的方法进行定性。同时,为确定各样品中挥发性MOSH组分的迁移性能,在时隔6个月之后,对以上样品采用同样的方法进行取样、检测、分析。最后,根据2次检测的结果,判断市售一次性纸质食品包装材料及制品中挥发性MOSH组分的迁移性,以确定其对食品安全性的影响情况。结果 结果表明,所测的16种样品中均含有挥发性MOSH组分,并且其含量随着时间而降低;同时发现,没有印刷图文或印刷图文面积极小的纸质包装制品中挥发性MOSH组分向外迁移的速度较低。结论 SPME-HSGC-MS适用于纸质包装材料或制品中挥发性(半挥发性)MOSH组分的检测与分析。为降低由纸质食品包装材料及制品中挥发性MOSH组分对人体产生的危害性,建议纸质包装材料或制品制作完成后,在不增加仓储压力的情况下,放置一段时间,并加大其存储空间的通风,再用于食品包装。The work aims to detect and analyze the content of volatile mineral oil saturated hydrocarbons(MOSH)components in paper food packaging products(such as boxes,bags,buckets,cups,etc.),so as to determine the volatility of volatile MOSH components in paper food packaging materials and products and the potential harm to packaged food(simulants).Samples were cut to small pieces(5 mm×5 mm),then extracted by solid phase microextraction,and lastly detected by headspace chromatography-mass spectrometry (HSGC-MS). The NIST mass spectral library, characteristicion fragment and standard sample comparison were combined to conduct qualitative analysis. In order to determine themigration performance of the volatile MOSH components in each sample, the samples were taken, detected and analyzedby the method mentioned above after 6 months. Finally, the results of the two tests were compared, and the migrationof the volatile MOSH components in the disposal paper food packaging materials and products on the market wasjudged to determine the impact on food safety. The results showed that all the 16 samples tested contained volatile MOSHcomponents and their content decreased with time. The migration velocity of volatile MOSH components was lower inpaper packaging products without printed graphic or with minimal graphic area. SPME-HSGC-MS is suitable for the detectionand analysis of volatile (semi-volatile) MOSH components in paper packaging materials or products. In order toreduce the harm of volatile MOSH components to the human body in the paper food packaging materials and products, itis recommended to place paper packaging materials or products for a period of time without increasing storage pressureand increase the ventilation of storage space before using them for food packaging.
