常见食品中邻苯二甲酸酯类增塑剂含量及食品包装材料中邻苯二甲酸酯类增塑剂迁移量的测定
Determination of phthalate plasticizers in daily foods and their migration from food packages
摘要
Abstract
A total of 16 phthalates in food samples (beverage,milk and wine) were analyzed by gas chromatography-mass spectrometry (GC-MS) combined with the sample preparation of liquid-liquid extraction and dispersive solid-phase extraction (dSPE).The limits of detection (LODs,S/N =3) for the 16 phthalates were fairly good,ranging from 0.005 to 0.025 mg/L.The relative standard deviations (RSDs) of the peak areas were less than 2%,showing good repeatability.In addition,the recoveries of phthalates in various matrices were generally ranging from 60% to 1 10%.In conclusion,the developed method can help the trace analysis of phthalates in beverage,wine and milk.In order to strictly investigate the migration of phthalates from the daily food packages like plastic wraps and storage bags,iso-octane was used as the simulant of fatty foods.The migration determined using the above optimized method showing the significant migration existing in plastic wraps and some unqualified products in current market is not meeting the national regulations about the migration limits of phthalates.关键词
