Abstract
Vino se ubraja u najstarije poljoprivredno prehrambene proizvode. Glavna karakteristika koja određuje kakvoću vina i ima vrlo važnu ulogu prilikom odabira vina od strane potrošača je aroma. Ona potječe dijelom iz sirovine, alkoholne fermentacije, a dio nastaje odležavanjem i njegovanjem mladog vina. Pojedine komponente arome nastaju tijekom odležavanja vina, a pojedine postupno nestaju te na taj način vino mijenja svoja organoleptička svojstva. Miris vina tvore tisuće hlapljivih komponenata, međusobno povezanih, tvoreći komplekse. Cilj ovog istraživanja bio je utvrditi sadržaj aromatičnih spojeva, polifenola te antioksidacijsku aktivnost u vinima sorte Cabernet Sauvignon dobivenim različitim tehnološkim postupkom proizvodnje. Utvrđeno je da tehnološki postupak proizvodnje utječe na sadržaj aromatičnih spojeva, polifenola i na antioksidacijsku aktivnost u vinu. Rezultati analize vina pokazali su da je vino dobiveno potpunom fermentacijom imalo veći sadržaj alkohola, dok je vino dobiveno ranije prekinutom fermentacijom imalo veći sadržaj tvari arome koje potječu iz sirovine, grožđa. Također, vino proizvedeno ranije prekinutom fermentacijom imalo je veći sadržaj polifenola te antioksidacijsku aktivnost.
Abstract (english)
Wine is one of the oldest agro-food products. The main characteristic that determines the quality of wine and plays a very important role in selecting wines by consumers is the aroma. It originates partially from raw material, alcoholic fermentation, and part of it is generated during aging and nurturing of young wine. Certain aroma components are formed during aging, but some of them gradually disappear, thus changing the wine's organoleptic properties. The smell of wine is formed by thousands of volatile components, interconnected, creating complexes. The aim of this study was to determine the content of aroma compounds, polyphenols and antioxidant activity in Cabernet Sauvignon wines obtained by various technological processes. It has been established that the technological process of production influences the content of aroma compounds, polyphenols and antioxidant activity in wine. The results of the wine analysis showed that the wine obtained by complete fermentation had a higher alcohol content, whereas the wine obtained by the previously discontinued fermentation had a higher content of aroma compounds derived from raw material, grapes. Also, the wine produced by the previously discontinued fermentation had a higher content of polyphenols and antioxidant activity.
