Rapid and Precise Discrimination of Wines by Means
of an Electronic Nose Based on Gas-chromatography

Abstract:

An electronic nose of the latest generation, based on the chromatographic principle, was used to analyze the volatile profile of various samples of wine in order to assess the possibility of differentiating wines based on various parameters such as their geographic origin, grapevine variety and its characteristics (such as noble/hybrid character), the yeasts used for fermentation in the winemaking process, the proportions of different wines used in blends or even fraud attempts such as the dilution with water. It was found that the multivariate data analysis procedures such as the Discriminating Factor Analysis, applied to the chromatographic data recorded using the electronic nose, allows for a very good discrimination of the mentioned wine samples. Keywords: wine, electronic nose, sample discrimination, multivariate statistics
