Application of volatile compounds distribution for the assessment of the Czech beer authenticity

Abstrakt

The main goal of this study was the evaluation of the possibility of Czech beer authenticity evaluation on the base of distribution of volatile compounds. For this purpose it is necessary in the first step to tune up suitable analytical procedure. Solid Phase Microextraction (SPME) was the method of choice as simple, effective and fast method of isolation of volatile compounds from beer. Gas chromatography/mass spectrometry (GC/MS) and orthogonal comprehensive gas chromatography with fast TOF-based mass spectrometry (GCxGC-TOF MS) were used as final analytical methods.
