摘要: 选用三片罐食品迁移物双酚A二环氧甘油醚（BADGE）及其6种双酚类物质衍生物为实验对象,探究了这些物质在模拟物体系中经不同灭菌方式后的稳定性以及各物质的转化产物。在此基础上,选取不同的储藏条件来进一步研究各物质之间的转化规律。结果表明:BADGE、BADGE·H2O和BADGE·HCl在常压灭菌后以及储藏过程中会发生水合,转化成相应的水化物。BADGE·2HCl、BADGE·2H2O和BADGE·H2O·HCl在常压条件下,性质比较稳定。BADGE·HCl、BADGE·2HCl和BADGE·H2O·HCl在经过高压灭菌后,三种氯化物在醇性模拟液中,会转变为BADGE及其水化物。本研究为金属包装材料中双酚类物质的迁移分析提供参考依据。Abstract: The stability and transformation products of bisphenol A diglycidyl ether( BADGE) and its derivatives from three- piece metal cans in simulants after different sterilizing processes were studied,and the transformation rules of these compounds under different storage conditions were further explored. Results showed that after atmospheric pressure sterilization and during the storage,BADGE,BADGE·H2O and BADGE·HCl hydrolyzed and transformed to their hydrates.BADGE·H2O·HCl,BADGE·2H2O and BADGE·2HCl were stable under the same conditions.However,the chloride of BADGE in ethanol transformed into BADGE and its hydrates after high pressure sterilizing.The study provided the references for the analysis of migrations of bisphenols from metal packaging materials.
