The Content of Biogenic Amines in Croatian Wines of Different Geographical Origins

Samples of white and red wines produced in two different wine-growing regions, coastal (Dalmatia) and continental (Hrvatsko zagorje) of Croatia, were analysed for biogenic amines content. Biogenic amines content was determined, and its concentration levels were associated to the geographical origin of the wine. Due to its high sensitivity, HPLC method with ultraviolet detector was used, including derivatisation step by dansyl chloride. The method was applied to detect and quantify 11 biogenic amines in 48 red and white wines. It was found that both Dalmatian red and white wines are characterized by tryptamine (0.23-1.22 mg L-1 ), putrescine (0.41-7.5 mg L-1 ) and ethanolamine (2.87-24.32 mg L-1 ). White wines from Hrvatsko zagorje region are characterized by content of isopentylamine (0.31- 1.47 mg L-1 ), putrescine (0.27-1.49 mg L-1 ) and ethanolamine (3.80-17.96 mg L-1 ). In contrast to white wines from Hrvatsko zagorje region, in red wines were found and equally presented all biogenic amines except ethylamine
