摘　　要：采用气相色谱-质谱联用法测定多种不同材质的食品接触材料中PAEs(18种邻苯二甲酸酯)的含量。结果表明,DIBP,DBP,DEHP检出率较高。模拟微波炉使用条件,研究了含有PAEs的食品接触材料在4种食品模拟物(蒸馏水、乙酸3%、乙醇水溶液15%、精炼橄榄油)中PAEs的迁移量和迁移比例。结果表明,样品在蒸馏水、乙酸3%、乙醇水溶液15%这3种模拟物中都是微量迁移,而在精炼橄榄油中迁移较大。通过研究微波条件对食品接触材料在精炼橄榄油中迁移量的影响,发现随着微波功率的增大和加热时间的延长,样品中PAEs向精炼橄榄油中的迁移量增大。Concentrations of phthalate acid esters(PAEs)(18 phthalates)in many different kinds of food contact materials were detected by using high performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS).The results showed that the detection rate of DIBP,DBP,DEHP was high.The migration and migration ratio of PAEs in four kinds of food mimics(distilled water,acetic acid 3%,ethanol aqueous solution 15%,refined olive oil)were investigated by simulating the conditions of microwave oven.The results showed that the migration behaviour was micro in distilled water,acetic acid 3%and ethanol aqueous solution 15%,but the migration behaviour was obvious in refined olive oil.The effect of microwave conditions on the migration of food contact materials in refined olive oil wastested.The results showed that the migration increased with increasing the microwave power and heating time.
