Bruker Wine-Profiling Module 3.1 for NMR FoodScreener

Bruker has released version 3.1 Wine-Profiling module of its NMR FoodScreener platform. The release improves coverage of white wines in the three most recent vintages and enhances coverage of certain regions, appellations and grape varieties.

Wine profiling by nuclear magnetic resonance (NMR) combines quality control and testing of authenticity. Based on 19,000 reference samples (an increase of 46% from version 3.0), the release delivers easy and cost-efficient analysis for quality and authenticity of samples regarding origin, variety and the addition of water.

The wine-profiling module has added capabilities for verification of geographical origin by country for white wines (Austria, France, Germany, Italy, Spain) and for red wines (Chile). It verifies special regions: Bourgogne (red, white), Languedoc (red), Rhone (red) and Loire (red), as well as certain appellations: Chablis (France) and Valpolicella (Italy), and one new grape variety: Verdejo (Spain).

The analysis of wine using NMR spectroscopy relies on the acquisition of the spectroscopic fingerprint specific to each individual sample. These metabolic profiles are compared to a large database of authentic wine samples using a multivariate statistical approach. This high-throughput technique provides a wide range of information that is both targeted (quantification of defined substances) and non-targeted (identifying deviations from reference spectra).
