The volatile composition of eight varietal wines
Vranec, Merlot, Cabernet Sauvignon, Temjanika and Chardonnay
from the Republic of Macedonia, and Portugieser,
Kékfrankos and Tokaji Aszú from Hungary has been characterized
by means of gas chromatography/mass spectrometry
technique. The wine volatile compounds were extracted
in dichloromethane, and the extracts were concentrated under
nitrogen. Forty-four volatile compounds have been identified
mainly using the NIST mass spectral library and by
comparison with the available standards used for quantification
as well. Differences between the wines were noted for a number of compounds, such as a higher concentration of
1-pentanol and 2-phenyl ethanol in the red wines. Monoterpenes,
linalool and terpineol were detected only in the
white wines, Chardonnay and Tokaji. Macedonian red wines
were characterized by a higher level of alcohols, while the
Hungarian wines contained a higher amount of esters, fatty
acids and lactones. A statistical treatment including one-way
ANOVA, followed by a Tukey’s test has been performed in
order to ascertain possible significant differences between
the wines studied, and principal component analysis to
study the possible grouping of the wines.
