中文摘要:
      目的 分析可加热塑料食品包装中的挥发性有机物( VOCs) 。 方法 以甲醇为溶剂,配制异丙醇、乙酸乙酯、苯、乙酸丁酯、乙苯、间 / 对二甲苯、邻二甲苯、环己酮的标准溶液, 利用顶空 / 气相色谱-质谱( HS / GC-MS) 技术对 7 种可加热塑料食品包装进行了检测分析,对比加热前后塑料食品包装中VOCs 的变化。 结果 原味酸牛奶包装袋在加热后环己酮的含量明显增加,小酥肉塑料包装盒在加热后异丙醇的含量增加比较明显,粽子塑料包装袋、玉米塑料包装袋、奶茶塑杯、自加热饭盒、微波饭盒在加热前后 VOCs 含量变化不大。 结论 这 7 种包装中的苯类溶剂残留量均超标。
英文摘要:
      Objective To analyze volatile organic compounds in heatable plastic food packages. Methods With methanol as solvent, standard solutions of isopropyl alcohol, ethyl acetate, benzene, butyl acetate, ethylbenzene, m / p-Xylene, o-Xylene and cyclohexane were prepared. Headspace gas chromatography and mass spectrometry ( HS / GC-MS) technology were used to determine and analyze eight volatile organic compounds ( VOCs) in seven heatable plastic food packages. Differences of VOCs in the packages before and after heating were compared. Results The content of cyclohexane in original yoghurt plastic package after heating was significantly higher than that in unheated package. The content of isopropyl alcohol in heated Xiaosurou plastic box obviously increased. The changes in the content of VOCs in Zongzi plastic bag, corn plastic bag, milk tea plastic cup, self-heating plastic dinner box and microwaveable plastic box were relatively small. Conclusion Residues of benzenes in the seven packages all exceeded the national standards.
