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.
