ABSTRACT
Determination of the oligosaccharide composition in different wort samples is important to monitor their change during the brewing process with different yeast types. In our work, the concentration of fermentable and non-fermentable sugars were monitored by capillary electrophoresis to observe the effect of two different types of yeasts, Saccharomyces pastorianus and Saccharomycodes ludwigii. The former first ferments the monosaccharides, then the higher sugar oligomers, such as maltose and maltotriose, to ethanol, while the latter fully ferments the monosaccharides, but ferments only very low percentages of the oligosaccharides. Therefore, breweries use Saccharomycodes ludwigii to produce beers with low alcohol content. The CE-LIF traces of the wort samples represented unique oligosaccharide signatures.
