Analysis of Aroma Components in Beer Using HS-20 and Nexis™ GC-2030

Beer contains an extremely large number of aromatic compounds, or aroma components. In this article, nine aroma components which have a large influence on the flavor of beer, including alcohols and esters, were analyzed in five types of commercial beer. A multivariate analysis (principal component analysis, hierarchical clustering analysis) of those analysis results was also conducted, and the beers were compared.
