Current Research: Developing methods for analyzing beer flavor compounds/working with local breweries in community-based research
Beer has played an influential role in society since its creation in the fifth millennium BCE. It continues to be a prominent part of human culture today, both socially and economically. This is evident through the increasing market for products of mass-production brewing companies and drastic proliferation in the small-scale brewing industry, the “microbrew movement.” A thorough understanding of the compounds contributing to flavor and aroma is an important field of research for brewers and consumers. Many compounds contribute to flavor and aroma. However, VOC’s from hops and yeast metabolism are the foremost contributors for the flavor and aromatic characteristics. Therefore, detailed analysis of VOC’s in beer provides valuable information regarding flavor and quality control.
Most large brewers today have the financial means to access the instrumentation necessary for analysis, while many small brewers do not. There are limited contract research facilities available that provide analysis for microbreweries. Even these cost upwards of $200 per sample, require a significant sample volume, and takes approximately two weeks to obtain results. In contrast, our methods provide local microbreweries more time and cost-efficient alternative for scientific analysis of beer. In our research, we have developed a novel approach, floating solid phase microextraction (FSPME), as a cost-effective method to prepare beer samples for analysis using standard gas chromatography and mass spectrometry (GC/MS) techniques. This has allowed us the opportunity to collaborate and conduct community-based research with local brewers to improve beer quality .
Our approach has already yielded positive results for the breweries with whom we collaborate, answering many of their questions and concerns. For example, we have analyzed the effects of centrifugation, dry hopping and fermentation time on beverage profiles which have informed changes in their procedures.
