Abstract

The malting process is a complex system involving two major groups of metabolically active organisms: the barley grains and the diverse microbial population naturally colonising barley. To create a tool for process development and optimisation, FTIR and gas chromatography were applied to detect volatile metabolites produced during industrial scale malting processes. The changes in microbial populations were also monitored. The main volatiles observed during the malting process were carbon dioxide, ethanol and acetaldehyde. Steeping rapidly activated the microbial population colonising the grain. A numerous and diverse yeast population was noticed in the various stages of industrial malting.
