Súhrn: The aims of this study was (i) to investigate the occurence of residual dipropylene glycol diacrylates (DPGDA) and tripropylene glycol diacrylates (TPGDA) in the three original paper stick packages of crystaline saccharose and in the packaged saccharose and (ii) to evaluate the efficiency of low density polyethylene (LDPE) coating on the decrease of DPGDA and TPGDA into food simulants: 10%, 50% and 95% ethanol solutions, 3% acetic acid, olive oil, Tenax, saccharose and NaCl. LDPE layer efficiency against migration of acrylates was compared with migration from plain paper. Using gas chromatography-mass spectrometry DPGDA was found in two packages in content 4 mg·kg-1 and 443 mg·kg-1, TPGDA in all packages at levels 40 mg·kg-1, 52 mg·kg-1 and 222 mg·kg-1. Concerning the transfer of diacrylates into food simulants at 40 °C the highest levels of migration were found for 95% ethanol when more than 80% of TPGDA and 30% of DPGDA were transported from packaging via LDPE into the simulant. The levels of migration into the other liquid simulants were much lower. The study proved that the layer of LDPE is a functional barrier against the penetration of diacrylates from packages into food simulants.
