Abstract
A method allowing parallel fingerprinting of proteins and maltooligosaccharides directly from untreated beer samples is presented. These two classes of compounds were detected by Matrix-Assisted Laser Desorption-Ionisation-Time of Flight-Mass Spectrometry (MALDI-TOF-MS) analysis of beer mixed with 2.5-dihydroxybenzoic acid solution. The maltooligosaccharide profiles acquired from the MALDI sample spot center were not found characteristic for beers of different source and technology. On the other hand, according to profiles containing protein signals acquired from crystals formed on the border of the MALDI sample spot, we were able to distinguish beer samples of the same brand produced by different breweries. The discriminatory abilities of the method were further examined on a set of 17 lager beers, where the fingerprints containing protein signals enabled resolution of majority of examined brands. We propose MALDI-TOF-MS profiling as a rapid tool for beer brewing technology process monitoring, quality control, and determination of beer authenticity. (C) 2012 Elsevier Ltd. All rights reserved.
Abstract (in Czech)
Byla vyvinuta metoda pro paralelní profilování proteinů a maltooligosacharidoun přímou MALDI-TOF MS analýzou neupravených vzorků. Zatímco maltooligosacharidové profily se neukázaly být charakteristické pro zdroj či použitou technologii, na základě proteinových profilů bylo možné rozlišit většinu vzorků piva dle značky či výrobce. Metoda je navržena jako rychlý nástroj pro monitoring výrobní technologie, kontrolu kvality a potvrzení původu vzorků piva.
