Abstract

Cilj završnog rada bio je opisati proizvodnju, kemijski sastav grožđa i bijelog vina te analizirati osnovne parametre kakvoće domaćeg bijelog vina iz vinogorja Vrgorac. Vino je proizvedeno u podregiji Dalmatinska zagora tradicionalnim postupkom u privatnoj vinariji od sorata Zlatarica, Medna i Kuč. Analiza vina je provedena kemijski i kromatografski. Analizirani su osnovni parametri kakvoće: ukupni šećer, alkohol, slobodni, vezani i ukupni sumpor te hlapive i ukupne kiseline. Papirnom kromatografijom dokazano je prisustvo mliječne, vinske i jabučne kiseline. Tekućinskom kromatografijom visoke djelotvornosti (HPLC) u vinu su detektirani etanol, glicerol i mliječna kiselina. Rezultati analiziranog domaćeg bijelog vina su u skladu s vrijednostima Pravilnika o vinu iz 1996. godine.

Abstract (english)

The goal of my final work was to describe production, chemical composition of grape and white wine and addtionally to analyse basic quality parameters of domestic white wine from Vrgorac vineyards. The wine is traditionally produced in a household of subregion Dalmatinska zagora from domestic grapes such as Zlatarica, Medna and Kuč. Analysis of wine was done by chemical and chromatographical methods. The basic parameters were analysed such as: total sugars, alcohol, sulphur and volatile and total acids. Thin-layer chromatography revealed the presence of lactic, tartaric and malic acid. High performance liquid chromatography (HPLC) detected in analysed wine ethanol, glycerol and lactic acid. The results of analysed domestic white wine are in accordance with the values from the Croatian wine regulations from year 1996.
