Abstract:
For the very first time, this study investigates the simultaneous migration of several metals and bisphenol compounds from coated tinplate cans into vegetable foods highly consumed worldwide. The role played by heat treatment, food type and brand, storage conditions, can denting and cooking food directly in cans is also assessed. Migration of bisphenol compounds (only BPA and BADGE·2H2O detected) was mainly affected by sterilization, whereas metal release was greatly influenced by storage. Based on a Principal Component Analysis different migration pattern groups were highlighted: BPA and Zn (and Pb to a lesser extent) showed similar migration trends, with dependence on food type, brand and storage temperature. Cd, Ni and Cu were similarly influenced by food type and can brand. Fe has a particular trend, with clear influence of storage time, and to a lesser extent of food type. Overall Fe and BADGE·2H2O migration were favored in acidic food.
