摘要:

采用4 种食品模拟物包括超纯水、30 g/L乙酸水溶液、10%乙醇水溶液和异辛烷对食品金属罐中4 种双酚物(包括双酚A、双酚F、双酚A二缩水甘油醚和双酚F二缩水甘油醚)迁移情况进行研究,并建立半经验的双酚物迁移规律数学模型。结果表明:4 种双酚物同时在10%乙醇溶液中出现最大迁移,且贮存温度和时间对迁移量变化有显著影响。根据模拟实验得到的迁移数据和Fick第二定律建立数学模型,初步确定扩散系数DP,再根据DP估计得到包材的特征参数AP的范围为35.38~48.48。

Abstract:

Four kinds of food simulants including ultrapure water, 30 g/L acetic acid-water solution, 10% ethanol-watersolution (V/V) and isooctane were used to study the migration characteristics of four kinds of bisphenol compounds includingbisphenol A, bisphenol F, bisphenol A diglycidyl ether and bisphenol F diglycidyl ether in food packaging metal cans. Thenthe semi-empirical migration rule of bisphenol compounds was established. The results showed that the food simulant ofethanol-water solution was the most suitable for bisphenol releases. Besides, storage temperature and time had a significanteffect on the migration. Based on the migration data and Fick’s second law, migration models were established to determinethe diffusion coefficient (Dp), which was then used to estimate the characteristic parameter of the package (AP), which rangedfrom 35.38 to 48.48.
