Abstract
The migration of bisphenol A (BPA) from epoxy-phenolic can coating into canned meat products, produced for the needs of the Serbian Armed Forces, was investigated in this work. The tinplate cans were made according to the special military demands, filled with the beef goulash or the meatballs in tomato sauce, and preserved by sterilization. The structure of internal can coating was analyzed by FTIR spectroscopy. The migration of BPA into content of the cans was investigated after storage under regular conditions in typical military facilities. The samples of beef goulash (BG) produced in 2010-2016, and the meatballs in tomato sauce (MB) produced in 2014?2017 were tested for the presence of BPA. Thereafter, the impact of storage temperature and degree of can damage on BPA migration was examined. Both meat products were thermostated on 20 and 40 ?C, and BPA level was measured after 3, 6, 9 and 12 months of storage. The level of BPA was determined in the content of undamaged cans, and cans with lower and higher degree of damage. The BPA was extracted from food with acetonitrile and the extracts were purified by QuEChERS procedure. The level of BPA was determined by LC?MS.
