Evaluation of beer deterioration by gas chromatography–mass spectrometry/multiv...

Beer stability is a major concern for the brewing industry, as beer characteristics may be subject to significant changes during storage. This paper describes a novel non-targeted methodology for monitoring the chemical changes occurring in a lager beer exposed to accelerated aging (induced by thermal treatment: 18 days at 45 ◦C), using gas chromatography–mass spectrometry in tandem with multivariate analysis (...
