Sažetak
This study was performed in order to determine changes in concentration of some aroma compounds during the alcoholic fermentation of the Plavac mali wine from the Peljesac peninsula, appellation Dingac. Higher alcohols and esters were detected by gas chromatography/headspace analysis. In all samples reductive sugar and ethanol have also been determined. Concentration of carbonyl compounds is the highest in the first phase of the alcoholic fermentation. Acetaldehyde content has been steadily decreased after three days of the alcoholic compounds, but synthesis of diacetyl were determined during all eight days of this process. Higher alcohols have been synthesized during the alcoholic fermentation, but content of this compounds is the highest in the first three days. Acceptation was 1- butanol which part were decreased. Very interesting is i-amyl alchol which concentration 150 mg/L were determinate. Higher alcohols in concentration of 0, 3 g/L contribute to the desirable of aroma of wine but higher concentration of these compounds have undesirable influence. Esters contribute most to the desirable aspect of the fermentation bouquet of wine. Ethyl acetate, ethyl propionate, isoamyl acetate, ethyl hexaonate, ethyl lactate and ethyl octanoate were identified. During first four days of the alcoholic fermentation the content of these esters have been increased.
