ActiveFood contact materials - Polymer - Determination of 1,2-dihydroxybenzene,1,3-dihydroxybenzene,1,4-dihydroxybenzene,4,4'-dihydroxybenzophenone and 4,4'dihydroxybiphenyl in food simulants - High performance liquid chromatography
食品接触材料 高分子材料 食品模拟物中1,2-苯二酚、1,3-苯二酚、1,4-苯二酚、4,4'-二羟二苯甲酮、4,4'-二羟联苯的测定 高效液相色谱法
Application Summary AI generated
This standard specifies a high-performance liquid chromatography (HPLC) method for quantifying five specific phenolic compounds—including dihydroxybenzenes and dihydroxybiphenyls—that may migrate from polymer food contact materials into food simulants. It is applied in the safety testing of plastic packaging, containers, and kitchenware to ensure compliance with migration limits for these substances under intended use conditions. The method is used by regulatory laboratories and quality control departments to verify that food contact polymers do not release harmful levels of these compounds into food.
