“…To propose a methodology aiming at fast non-destructive metabolomic characterization of a beer, exploring its compositional profile, and highlighting potential trends or peculiar samples, Cavallini et al [ 57 ], combined NMR spectroscopy and chemometrics. In this study, one hundred pale beers from different brands were analyzed.…”

Achieving beer quality and stability remains the main challenge for the brewing industry. Despite all the technologies available, to obtain a high-quality product, it is important to know and control every step of the beer production process. Since the process has an impact on the quality and stability of the final product, it is important to create mechanisms that help manage and monitor the beer production and aging processes. Multivariate statistical techniques (chemometrics) can be a very useful tool for this purpose, as they facilitate the extraction and interpretation of information from brewing datasets by managing the connections between different types of data with multiple variables. In addition, chemometrics could help to better understand the process and the quality of the product during its shelf life. This review discusses the basis of beer quality and stability and focuses on how chemometrics can be used to monitor and manage the beer quality parameters during the beer production and aging processes.

“…Today, metabolite fingerprinting by NMR methods is a fast-growing field which is increasingly applied for quality control of foods and herbal products [47]. With reference to beer, bitterness, autoxidation reactions, changes during aging, and other peculiar properties can been investigated by high-resolution NMR techniques [48][49][50][51][52]. The main components of the αand β-acid families of hop have been identified, and their structures were confirmed by high-resolution mass spectrometry and MS/MS experiments.…”

Beer is a complex aqueous mixture of organic and inorganic compounds, such as carbohydrates obtained from barley or wheat malts, hops and yeast, ethanol, proteins, vitamins, and minerals. Phenols and their derivatives obtained by chemical interactions with biogenic amines, together superior alcohols and amino acids, are the other compounds present in minor proportions in beer, Phenolic components possess high antioxidant activities, and regulate the oxidative stability of beer, although bitterness of this beverage originates from hops. Since these antioxidants can produce beneficial effects on the human health after consumption, it is challenging to have in hand the molecular profiles of beers, in order to investigate their contents in bioactive compounds. Today, a significant number of small producers have strongly invested in craft beers, produced by using different hop blends, starting materials that are rich in phenolic antioxidants. The present work discloses an instrumental analytical method which enables the rapid obtainment of the molecular profiling of craft beers, with the assistance of selective extractions made by using multi-walled carbon nanotubes (MWCNTs). In this investigation, high-resolution 1H NMR, and LDMS and MS/MS analysis were applied for the “beeromic” analysis of a craft beer brewed in Calabria (the Southern part of Italy). The spectral data, confirmed that this kind of beer predominantly contains the hop bitter metabolites humolones and lupulones, also highlighting the presence of phenols and phenolamides which are known for their bioactivity against cancer. A profile of the principal volatile hop components was also obtained by GC-MS.

“…92 Along this line, a combination of NMR spectroscopy and chemometrics was proposed by Cavallini et al to characterize beer. 93 The authors compared two multivariate approaches: the full spectra analysis and the analysis of the chemical features extracted by multivariate curve resolution. In addition, PCA was used for exploratory purposes; pareto scaling was used to preprocess the NMR spectra dataset, while autoscaling was used to preprocess the features dataset.…”
