Súhrn: The aims of this study were to investigate the occurence of residual dipropylene glycol diacrylates (DPGDA) and tripropylene glycol diacrylates (TPGDA) in three original paper stick packages of crystaline saccharose and in the packaged saccharose, and 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, sorbent Tenax, saccharose and NaCl. LDPE layer efficiency against migration of acrylates was compared with their migration from plain paper. Using gas chromatography-mass spectrometry, DPGDA was found in two packages in contents of 4 mg·kg-1 and 443 mg·kg-1, while TPGDA was found in all packages at levels of 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 the 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 penetration of diacrylates from packagings into food simulants.
