PET膜中26种化学元素向酸性食品模拟物的迁移
|
摘要
目的研究4种印刷不同油墨的PET薄膜在酸性条件下26种化学元素的迁移行为。方法采用电感耦合等离子体发射光谱(ICP-OES),测定铅、镉、铬等26种化学元素在PET薄膜中的初始含量;采用电感耦合等离子体质谱(ICP-MS)测定这26种化学元素向食品模拟物(体积分数为3%的乙酸)的迁移量。结果铅、镉、铬等26种元素的迁移量随着温度和时间的增加而增大,并且均能达到各自的迁移平衡。ICP-OES方法的加标回收率为80.2%～109.7%,其相对标准偏差(RSD)为0.3%～12.9%;ICP-MS方法的加标回收率为83.1%～118.6%,其相对标准偏差为0.7%～14.8%。结论 26种化学元素向体积分数为3%乙酸的最大迁移量均低于标准限量值。
The work aims to study the migration of 26 chemical elements in PET films printed with four different inks under acidic conditions. Inductively coupled plasma-optical emission spectrometry(ICP-OES) was used to determine the initial content of 26 chemical elements in food plastic packages, including lead, cadmium, chromium, and so on. Inductively coupled plasma-mass spectrometry(ICP-MS) was used to determine the migration of these elements to food simulant(3% acetic acid). The amount of migration of 26 elements such as lead, cadmium and chromium increased with the increase of temperature and time, and reached the respective migration equilibrium. The spike recovery of ICP-OES method was 80.2%～109.7% and the RSD was 0.3%～12.9%. The spike recovery of ICP-MS method was 83.1%～118.6%, and the RSD was 0.7%～14.8%. The maximum migration to 3% acetic acid of 26 chemical elements are all below the standard limit values.
