25 June 2013: Bruker Chemical and Applied Markets (CAM), Fremont, California, US: Bruker has released a set of application notes detailing off-flavor beer analysis using the new 456-GC-based Beer Analyzer. The technique provides reliable trace analysis of vicinal volatiles, such as ketone and sulfur components, that develop during the brewing process and, in excess concentration, contribute to unpalatable tastes. The 456-GC analyzer is available with two or three channel mode to provide quality control for use within breweries and QC laboratories, respectively. This ensures a consistently high product quality, independent of production time or product location. The application notes are downloadable at http://bit.ly/BCA529
Bruker Beer Analyzers reliably analyze vicinal volatiles that contribute to bad tasteThe application notes demonstrate how two and three channel 456-GCs are used to identify and quantify the key flavors within the beer, malt and wort brewing processes. The two channel set up is best suited to local breweries where it is capable of batch-to-batch product confirmation tests, while the increased sensitivity of an additional third channel allows identification of trace components such as dimethyl sulfide (DMS), which indicate the possible presence of bacterial contamination. The components threshold covers ppm down to sub ppm range to accommodate the human sensitivity to flavors. Three channel analysis achieves this level of sensitivity through incorporation of flame ionization, pulsed flame photometric and electron capture detectors.
“The 456-GC based beer analyzer with the new intuitive ChromSync software is optimized perfectly for the analysis of “off flavor” in beer,” commented Bruker CAM Product Marketing Manager Hans van den Heuvel. “Maintaining the high quality of taste and smell is extremely important for reputation,” noted Dr van den Heuvel. “Breweries can no longer solely rely on their nose.”
