Abstract:

The effect of ultra high pressure (UHP) treatment on aroma components of ice wine was investigated. The
aroma components were analyzed by capillary gas chromatography-mass spectrometry (GC-MS) after solvent extraction
and their relative contents were determined by peak area normalization method. The results showed that UHP treatment
caused changes in aroma components of ice wine. The predominant aroma compounds including isoamyl alcohol, phenethyl
alcohol, diethyl succinate, ethyl acetate, and ethyl hexanate were changed obviously. Furthermore, the aroma of ice wine was
made richer and softer after UHP treatment at 300 MPa.

Key words: ice wine, ultra high pressure, aroma components, gas chromatography-mass spectrometry (GC-MS)
