| 520 | |a A combination of FTIR and chemometrics was applied to classify Slovenian whitewines. The identification of the geographical origin of wines is of greatinterest for wine consumers and producers since it may provide determinant criteria for guarantee of quality. Many researches described the possibilities of prediction of wine origin using efficient methods of wine components analysis connected with multivariate data analysis. The aim of our work is focused on white wine classification. Wine samples were scanned in transmission on a WineScan FT 120 from wave numbers 926 to 5012 cm-1. All samples were sourced from 2004 to 2006 vintage. The present study deals with description and classification of the wine samples originated from several regions of south-west Slovenia by means of the following variables: relative density, content of total, non-volatile and volatile acids, ash, reducing sugar, free sugar, SO2, ethanol and pH. An important additionally available variable was sensorial quality of wine. This sensory variable positively correlates with content of ethanol and content of volatile acids. The effect of the variety of wine and geographical origin was examined and many significant differences were found in the mentioned descriptors. | ||
