Alternative GC?MS approaches in the analysis of substituted pyrazines and other volatile aromatic compounds formed during Maillard reaction in potato chips

Popis výsledku v původním jazyce

Several methods have been developed for the analysis of substituted pyrazines and related substances in potato chips. Following separation/detection approaches (all employing head-space solid phase microextraction, HS-SPME, for volatiles sampling), havebeen critically assessed in our study: (i) gas chromatography?ion trap mass spectrometry (GC--ITMS), (ii) gas chromatography--time-of-flight mass spectrometry (GC--TOFMS); (iii) comprehensive two-dimensional gas chromatography--time-of-flight mass spectrometry (GCxGC--TOFMS). Although in none of the tested systems full chromatographic resolution of some isomeric pairs could be achieved, the use of GCxGC--TOFMS offered the best solution, mainly because of distinctly lower limits of quantification (LOQs)for all of 13 target alkylpyrazines. In addition to good performance characteristics, a non-target screening and tentative identification of altogether 46 N-containing heterocyclic compounds (pyrazines, pyrrols, pyridines, pyrrolidinones,
