Horáková, Lenka ; Machát,, Jiří (referee) ; Diviš, Pavel (advisor)
This diploma thesis deals with the chemical characterization of Frankovka red wines and the possibility of using chemical analysis of wines to distinguish Frankovka wines from VOC Modré hory from other Frankovka wines from the Moravian wine region. The theoretical part describes viticulture in the Czech Republic, the characteristics of the Frankovka variety and the wine classification system in the Czech Republic. The next part describes in detail the association VOC Modré hory, the red wine technology and the use of chemometry for wine authentication. The experimental part deals with the determination of the elemental profile of wines by ICP-MS and ICP-OES methods, analysis of selected phenolic substances by HPLC-MS and analysis of organic acids by IC. Furthermore, the analysis of the aromatic profile of wines was performed using the technique HS-SPME-GC-MS and the total content of phenolic substances in wines was determined by the MAS method. A total of 24 wine samples were analyzed, where 12 samples came from VOC Modré hory and another 12 wines came from other Moravian wine regions. Statistical analysis techniques (Mann-Whitney U-test and PCA) were used to classify wine samples into groups in order to separate wines from VOC Modré hory and other wines from other Moravian regions. The results of this work showed that with the help of chemical analyzes and statistical techniques it was possible to distinguish wines from VOC Modré hory from other wines from the Moravian wine region.
