中文摘要:

      目的 研究不同食品包装材料中邻苯二甲酸酯(phthalate esters, PAEs)的迁移规律。方法 采用气相色谱-质谱法(gas chromatography-mass spectrometry, GC-MS)对不同温度、不同时间条件下PAEs从食品包装材料中向水、4%乙酸、50%乙醇与异辛烷食品模拟物中的迁移规律进行研究。结果 PAEs的迁移受食品模拟溶液、温度、时间、包装材料的影响。不同食品模拟物中迁移率为: 异辛烷＞50%乙醇＞4%乙酸≈水; 在同一种食品模拟物中, 随着迁移时间延长和温度增加PAEs迁移量增大, 温度越高迁移速率越快; 食品包装材料的材质不同, PAEs含量不同, PAEs含量越高的包装材料迁移到食品中的量也越大。结论 本研究可以为食品的加工生产、存储、运输过程的安全控制提供理论基础和方法依据。

英文摘要:

      Objective To investigate the migration rules of phthalate esters (PAEs) from different packaging materials of food. Methods The migration rules of PAEs from food packaging materials to food simulants of water, 4% acdic acid, 50% ethanol and isooctane under different temperatures and different time were investigated by gas chromatography-mass spectrometry (GC-MS)．Results It was proved that the food simulant solution, temperature, time and contact materials had effects on the migration of PAEs. The migration of PAEs in different food simulants were in the order: isooctane＞50% ethanol＞4% acdic acid≈water. In the same food simulant, the PAEs migration content increased with the increase of time and temperature, and the migration rate increased as the temperature rose. The migration was related to the content of PAEs in packaging materials, and the migration amount had a positive correlation with the PAEs content in packaging materials. Conclusion The research can provide a theoretical basis and judging method for controlling food safety in production, storage and transportation processing.
