三片食品罐外壁涂膜中有害物质向内涂的迁移
Migration of Hazardous Substance Residues in the External Coating of Three-Piece Food Cans
摘要
Abstract
The migration of residual hazardous chemical agents including melamine,benzene and toluene from external can coatings to internal coatings during the stacking process was studied in this paper.A high performance liquid chromatography（HPLC） method was used to determine the substances in three different simulated aqueous food systems,including distilled water,3%（m/V） acetic acid solution and 10%（V/V） ethanol solution.The migration was monitored in the cans stacked at constant temperature（30 ℃）,moisture（（60 ± 2）% RH） and pressure（3.4 kPa） for two months.It was found that all the harmful substances in the exterior coatings were migrated into the internal wall of the food cans in the migration range of 0.04-1.60 μg/mL,which had a great impact on the safety of inner wall and probably caused further pollution of canned foods.关键词
