VOLATILE COMPOUNDS OF BLACK-CURRANT JUICE AND WINE

Volatile compounds of blackcurrant juice, concentrate and wine were analysed by applying a dynamic headspace gaschromatographic method based on selective capillary column trapping. A significant sensorial difference between the wine made from blackcurrant juice and that from concentrate was found by duo-trio assessment for aroma, while only a slight difference was observed in the volatile composition of the wines. Blackcurrant wines contained only a few terpene compounds, whereas numerous terpenes were identified from the juice. Differences between the blackcurrant juice and concentrate were found, with some terpene compounds appearing in higher amounts in the former.
