Quantitative Monitoring of the Fermentation Process of a Barley Malt Mash by Benchtop 1H NMR Spectroscopy

Abstract In order to investigate benchtop NMR spectroscopy as a monitoring tool for fermentation processes, we used barley malt mash and took various samples over time analysed them by with 3-(trimethylsilyl)-2,2,3,3-tetradeuteropropionic acid sodium salt (TSP-d4) an internal standard the quantification of ethanol validated results two different enzymatic test kits analysis. We could show that between were consistent having much lower deviation. Finally, discussed applicability method well possibility quantify other substances.
