Abstract

The content of dibutylphthalate (DBP) and di- (2-ethylhexyl) phthalate (DEHP) in samples of packages used for packaging meat productsand the phthalate migration from packaging materials to meat products were studied. Five samples of textile packaging intended for cooked meat production were analysed as well asthe final product which was filled into packages. Subsequently an analysis was carried out (after 1, 7, 14, 21, and 28 days of storage) of the finished meat products stored over the course of their intended shelf life at ambient temperature of 4 °C. Determination of phthalates was conducted by high performance liquid chromatography (HPLC) method with UV detection at a wavelength of 224 nm on the Zorbax Eclipse C8 column. The content of phthalates in the final product was below the limit of quantification. According to the Regulation of the Commission (EU) No. 10/2011, the specific migration limit of products intended for food contact is 1.5 mg.kg-1of food simulant for DEHP and 0.3 mg.kg-1 for DBP. After filling and the first day of storage of the meat product, four package samples release the said phthalates to an extent that it exceeded the limits of the Commission Regulation (EU) No. 10/2011. Already after the seventh day of storage, all samples (with the exception of sample 2 for DBP) exceeded SMLs. Monitoring of each phthalate migration in individual samples during storage (for 28 days) produced a rising tendency.  In sample 1, DBP increased from 0.40 to 3.37 mg.kg-1, while DEHP from 0.58 to 14.66 mg.kg-1. In sample 2, DBP increased from ≤0.2 mg.kg-1 to 4.34 mg.kg-1, whileDEHP from 1.46 to 28.20 mg.kg-1. In sample 3, DBP increased from ≤0.2 mg.kg-1 to  8.27 mg.kg-1, while DEHP from 1.67 to 14.84 mg.kg-1. In sample 4, DBP increased from 0.27 to 6.12 mg.kg-1, while DEHP from 2.37 to 13.22 mg.kg-1. In sample 5, DBP increased from 0.32 to 11.11 mg.kg-1, while DEHP from 1.91 to 15.42 mg.kg-1.
