The understanding of the migration of mercury from packaging materials to food stuffs is the prerequisite for the development of food safety regulations. In this article, the migration of mercury from food paper-plastic packaging containers to four food stimulants under different migrated temperatures is studied. The results show that the mobility and the maximum migration volume of mercury increase at certain temperatures when the migration time is extended. It is also noted that the time to reach equilibrium is reduced as the temperature increases. Meanwhile, different solvents appear various different while the rates of migration are 3% acetic acid >10% ethanol >20% ethanol >50% ethanol. But they show the same trend at the different temperatures. Our data suggest that different solvents, temperatures, and food stimulants affect the migration rates, and ameliorate those conditions will reduce migration and promote food quality.
了解汞从包装材料向食品中迁移的情况是制定食品安全法规的前提。本文研究了在不同迁移温度下，食品纸塑包装容器中汞向四种食品刺激物的迁移情况。结果表明，随着迁移时间的延长，在一定温度下，汞的迁移率和最大迁移量增加。还注意到，随着温度的升高，达到平衡的时间缩短。同时，不同的溶剂在不同的温度下，其迁移率为 3%乙酸>10%乙醇>20%乙醇>50%乙醇。但它们在不同温度下呈现出相同的趋势。我们的数据表明，不同的溶剂、温度和食品刺激物会影响迁移率，改善这些条件将减少迁移并促进食品质量。
