石墨烯/低密度聚乙烯复合包装膜中2种抗氧化剂向食品模拟物异辛烷的迁移
Migration of Two Antioxidants from Graphene/Low Density Polyethylene Composite Food Packaging Films to the Food Simulant Isooctane
摘要
Abstract
A high performance liquid chromatography (HPLC) method was established for detecting two antioxidants (Irganox1076 and Irgafos168) in graphene/low density polyethylene (LDPE) composite food packaging films.The effect of time,temperature and the presence of graphene and graphene nanoplatelets on the migration of the antioxidants from LDPE films to isooctane as a fatty food simulant was studied.The interactions of the two antioxidants with isooctane during migration were discussed.The experimental results showed that the migration rates of the antioxidants increased until reaching equilibrium with increasing time or temperature.The antioxidants synergistically affected the migration of each other.The presence of graphene and graphene nanoplatelets hindered the migration of the antioxidants due to their agglomeration and adsorption capacity.关键词
