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10 μg/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。

Abstract: 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 10 μg/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.

Key words: diaminodiphenylmethane; high-salt foods; high-sugar foods; laminated food packaging bags; migration; food simulants
