The migration of photoinitiators, phthalates and plasticizers from two paper and cardboard materials into food simulants (50% and 95% EtOH and Tenax) and foodstuffs (rice, cereals and milk powder) was studied. In the case of liquid simulants migration was observed to reach the equilibrium after 60 min and depended on the material type and the physicochemical parameters of the migrants, whereas the temperature (room temperature and 60 °C) did not show significant effects. The study of migration of the compounds from a baking paper to Tenax at high temperatures (150 and 250 °C) evidenced an increment of migration when increasing temperature, except for the most volatile analytes. Finally, the migration to foodstuffs was studied using fully validated analytical protocols. Overall, the comparison of the migration rates demonstrated that Tenax was adequate for the simulation of the migration to rice and cereals, but underestimated the migration to infant milk powder, for which 95% EtOH resulted a more suitable simulant.
研究了两种纸和纸板材料中的光引发剂、邻苯二甲酸酯和增塑剂向食品模拟物（50%和 95%乙醇和 Tenax）和食品（大米、谷物和奶粉）中的迁移情况。对于液体模拟物，迁移在 60 分钟后达到平衡，这取决于材料类型和迁移物的物理化学参数，而温度（室温与 60°C）没有表现出显著影响。研究烘焙纸中化合物在高温（150 和 250°C）下向 Tenax 的迁移情况表明，除了最易挥发的分析物外，随着温度的升高，迁移量会增加。最后，使用经过充分验证的分析方案研究了向食品中的迁移情况。总体而言，迁移率的比较表明，Tenax 适用于模拟向大米和谷物的迁移，但对婴儿奶粉的迁移估计不足，对于婴儿奶粉，95%乙醇则是更合适的模拟物。
