The report is focused on determining the level of di-n-butyl phthalate (DBP) and di-2-ethylhexyl phthalate (DEHP) in materials used for packaging meat products and monitoring the extent of PAE migration into meat products after thermal treatment. Was analyzed 50 samples of packaging. The DBP concentration ranged from 0.19 to 23.95 µg.dm-2 and that of DEHP was between 0.01 and 103.33 µg.dm-2. Analysed packages containing higher concentrations of phthalates (5 samples) were subsequently used for monitoring the phthalate migration into the product due to thermal treatment. The determination of phthalates was conducted using high-performance liquid chromatography (HPLC) with UV detection at a wavelength of 224 nm. The DBP concentration ranged from 0.19 to 23.95 µg.dm-2 of the sample surface and that of DEHP was between 0.01 and 103.33 µg.dm-2 of sample surface. With regard to the specific migration limit (1.5 mg.kg-1 for DEHP and 0.3 mg.kg-1 for DBP), four of the analysed samples packages (a total of 5 samples) ceased to meet legal limits after thermal treatment, i.e. 70 °C in the product core for 10 minutes. Our analysis has confirmed that the migration of phthalates is influenced by temperature.
