Beer volatile terpenic compounds arise from a network of variables, namely from plant raw-materials metabolism, yeast metabolism, among others, and may suffer modifications during brewing. In order to increase the molecular understanding of beer volatile terpenic compounds, this work intends to perform a comprehensive characterization of these molecules on lager beer, using an advanced multidimensional chromatographic methodology. This research comprises the most detailed screening of lager beer terpenic compounds through the putative identification of 94 mono and sesquiterpenic compounds, distributed over 6 chemical families: alcohols, aldehydes, esters, ketones, hydrocarbons, and oxides. The terpenic profiles allowed the beer terpen-typing according to samples' category clustering: macro and micro-brewer beers. This study adds further insight to the lager beer terpenic volatile composition, and could be applied in large-scale studies in different contexts, namely for understanding the distinctive beer styles or for beer typing.
啤酒挥发性萜类化合物源于一系列变量,即植物原料代谢、酵母代谢等,并且在酿造过程中可能会发生变化。为了提高对啤酒挥发性萜类化合物的分子认识,本工作旨在使用先进的多维色谱方法对拉格啤酒中的这些分子进行全面表征。本研究通过假定鉴定了 94 种单萜和倍半萜化合物,对拉格啤酒萜类化合物进行了最详细的筛选,这些化合物分布在 6 个化学家族中:醇类、醛类、酯类、酮类、烃类和氧化物。萜类特征允许根据样品类别聚类对啤酒进行萜类分型:大啤酒和小啤酒。这项研究进一步深入了解了拉格啤酒的萜类挥发性成分,并且可以应用于不同背景下的大规模研究,即用于了解不同风格的啤酒或进行啤酒分型。
