The article presents the results of the global migration, sensory evaluation, content of styrene and the other substances from the selected polystyrene packaging intended for the chocolate products. The results obtained do not exceed the overall migration limit (10 mg/dm²). Styrene monomer content, determined by gas chromatography was from 180 to 230 mg/kg. It was found that the content of styrene in the package at 210 mg/kg causes a slight change in odor of packaging. For packages containing more than 230 mg/kg of styrene, in a preliminary assessment of odor intensity is clearly perceptible odor (3 in assessment scale). A negative result obtained in the study of sensory disqualify the package, even though the level is below the overall migration limit. SPME method combined with GC/MS gas chromatography and mass detection is a good complement to sensory analysis of food packaging.
