食品接触塑料中化学成分迁移研究方法进展

塑料以其优良的物理化学性能和低廉的价格广泛应用于食品接触制品中。然而食品长期与塑料包装接触可能导致塑料中化学成分向食品中迁移,进而造成食品污染,并最终危害消费者的身体健康。故食品接触塑料中化学成分的迁移行为受到国内外政府机构和科研工作者的广泛关注。本文简述了食品接触塑料迁移实验中食品模拟物的选择、迁移实验条件的设定,以及受限物质的检测方法。并对食品接触塑料中的光引发剂、重金属元素、增塑剂等三类化学成分的迁移规律的研究进行综述。

Review on migration method of chemical substances in polymeric food contact material

Because of the lower price and the excellent physical and chemical properties, plastics have been widely applied in food packaging industry. However, during contacting with food at long time, part of the chemical substances from polymeric food contact materials may migrate into food. The contaminated food ate by consumer may cause some health problems. Hence, the migration of chemical substances in food packaging materials has been drawn great attention with governmental agencies and researchers. This article reviewed the research progress of selection with food stimulants, experiment condition setting and detection method of certain substance. The migrations of photoinitiator, heavy metals and plasticizers in food contact materials have also been summarized.
