通过纸张表印油墨的实验室印制方法,模拟真实纸包装油墨中四种增塑剂向食品模拟物Tenax的迁移,使用气相色谱法检测不同温度（50℃、70℃和100℃）、纸张克重（240g/m2和400g/m2）和增塑剂初始含量下的迁移量。结果表明,纸包装油墨中增塑剂的迁移行为由其扩散系数和分配系数决定,温度和纸张克重对增塑剂迁移行为影响较大,实际中要避免增塑剂的迁移对人体造成的危害。
A series of food safety incidents have caused widespread concern over the safety of plasticizer.Three phthalates(dibutyl phthalate(DBP),bis(2-ethylhexyl) phthalate(DEHP),di-n-octyl phthalate(DOP)) and a new environmental plasticizer acetyl tributyl citrate(ATBC) are commonly used in inks.Gas chromatography (GC) was used to measure the migration of four plasticizers from inks in lad-made printing paper to food stimulant(Tenax) at different temperature(50 ℃,70 ℃ and 100 ℃),different paper weight(240g/m2 and 400 g/m2) and the different initial content of plasticizers.The results show that the lab-made printing paper can stimulate the real paper packaging with inks and the migration of plasticizers from inks depends on the diffusion and partition coefficients.The migration behaviour is significantly affected by the temperature and paper weight. Maximum migration increases with increasing temperature and decreasing paper weight.
