摘　　要：采用液相色谱-质谱(liquid chromatography-mass spectrometry,LC-MS)法检测二氨基甲苯(diaminotoluene,TDA)和二氨基二苯甲烷(diaminodiphenylmethane,MDA)同分异构体的迁移量。调查了市场上10种食品复合袋中TDA和MDA向4%乙酸的迁移水平。此外,将盐析、糖析辅助液液萃取与LC-MS结合,研究氯化钠和蔗糖对食品复合袋中2,4’-MDA和2,2’-MDA向10%乙醇溶液和水迁移的影响。结果显示:4,4’-MDA、2,4’-MDA和2,2’-MDA在4个样品中被测出,其中一个样品的MDA总迁移量超过10μg/kg。盐、糖的存在对2,4’-MDA和2,2’-MDA向10%乙醇溶液和水迁移产生显著影响(P<0.05),迁移量随着食品模拟物中盐、糖质量浓度的增加(2、5、10、15、20 g/100 mL)显著降低(P<0.05)。对用于高盐、糖食品的包装迁移测试时,可能需要调整食品模拟物。Liquid chromatography-mass spectrometry(LC-MS)was used to determine the migration of the isomers of diaminotoluene(TDA)and diaminodiphenylmethane(MDA).The migration levels of TDA and MDA from 10 samples of laminated food packaging bags to 4%acetic acid were investigated.In addition,salting-out and sugaring-out assisted liquid-liquid extraction combined with LC-MS was used to explore the effect of sodium chloride and sucrose on the migration of 2,4’-MDA and 2,2’-MDA from laminated food packaging bags to 10%ethanol and water.The results showed that 4,4’-MDA,2,4’-MDA and 2,2’-MDA were detected in four samples,and the total migration of MDA in one of the samples exceeded 10μg/kg.The presence of salt and sugar had a significant effect(P<0.05)on the migration of 2,4’-MDA and 2,2’-MDA to 10%ethanol and water.The migration levels decreased significantly(P<0.05)with increasing salt and sugar contents in food simulants(2,5,10,15,20 g/100 mL).Adjustment of food simulants may be needed for packaging material migration tests on foods with high salt or sugar content.
