Chemometric characterization of Slovenian red winesIvanović, Milena (Avtor) Petek, Anja (Avtor) Islamčević Razboršek, Maša (Avtor) Kolar, Mitja (Avtor) Slovenian red winesquality parameters of winepolyphenolschemometric analysisTotal phenolic (TPC), flavonoid (TFC) and tannin (TTC) contents, total $SO_2$, total acids, pH, and reducing sugars were measured in twenty five Slovenian red wines from three key wine producing regions, Podravje, Posavje and Primorska. The results were chemometrically analysed and the wines were classified according to wine growing region and vine variety. Principal component analysis proved that TPC, TFC and TTC contents were primarily responsible for variation in the wines. Additionally, linear discriminant analysis (LDA) was performed and resulted in the satisfactory classification of samples by both vine variety and region.20172017-10-03 09:48:42Znanstveno delo68635ISSN: 1318-0207UDK: 66OceCobissID: 14086149COBISS_ID: 20730646DOI: 10.17344/acsi.2016.2868ISSN pri članku: 1318-0207NUK URN: URN:SI:UM:DK:KDTHXVG3sl
