Establishment of chemical compounds responsible for odorant areas of three wines from local grape varieties from Moldova

Abstract

Three wines from local grape varieties from Republic of Moldova were submitted to both sensory and gas chromatography – olfactometry analyses (GC-O). Through descriptive analysis, a set of aroma attributes has been described. In order to identify these odor active compounds, the wines were evaluated using qualitative detection frequency analysis (n=7). The panelists generated in total 697 descriptions distributed in 126 odorant areas (OAs), but only 565 (81 %) distributed in 45 OAs were validated as being representative. According to coincidence of gas chromatographic retention data and on the similarity of odor with standards were identified the chemical compounds responsible for odorant areas.
