- Abstract
Çanakkale Bozcaada region, which has witnessed different cultures in different periods for centuries due to its strategic location and wines obtained from grapes belonging to the Vitis vinifera L. species, whose traditional names are Karalahna, Çavuş and Karasakız, have been consumed by the local people for years. Wine is a traditional fermented beverage rich in phenolic substances and antioxidant properties, due to the production process, especially during maceration stage, where grape berries are processed with their skins. The geographical structure, plant flora and climate of the region where the grapes grow can create different quality characteristics in grapes, and this affects the quality of the wine through wine processing methods. In this study, to determine some antioxidant activity values of wines produced from Karalahna, Karasakız, and Çavuş grapes grown in Bozcaada. 2, 2-Diphenyl-1-picryl-hydrazyl (DPPH·) free radical scavenging activity, total phenolic substance (Folin-Ciocalteu), reducing power, total flavonoid, anthocyanin, and condensed tannin amounts were measured. DPPH·% Inhibition value of Karalahna wine was found to be 90.6±1.14, condensed tannin was 54.22±0.612 µg CE/g, anthocyanin was found to be 2.46±0.09 mg cyanidin-3-glucoside/g. The results obtained were examined by comparing them with other wine samples.
