- Abstract
A determination method for analyzing the plasticizer phthalate acid esters (PAEs) in beer by headspace solid-phase microextraction-gas chromatography-mass spectrometry (HS-SPME-GC/MS) was established in this tests. The migration amount of PAEs in 6 kinds of beer commercially available and inner gasket of bottle cap in beer and simulants (ethanol solution volume fraction 10%) under 3 migration test conditions were determined by single point standard addition method. The beer samples were extracted by 50 μm polydivinylbenzene/carbon molecular sieve/polydimethylsiloxane (DVB/CAR/PDMS) extraction head and incubated in 55 ℃ water bath for 60 min. 16 PAEs components were quantified by this method. The results showed that the migration amount of DBP in beers with PVC and PE inner gaskets was highest by determining PAEs of beer, which was 9.48 μg/L and 8.26 μg/L, respectively, while the migration amount of DIBP and DEHP was lower. However, the contents of DEHP in ethanol solutions of 10% volume fraction was higher. It could be known by experiment that temperature and time were important factors in the increase of PAEs in beer. It should be strictly forbidden to store beer horizontally, upside down or at high temperature to prevent beer from contacting the inner gasket.
