GAS CHROMATOGRAPHY COUPLED WITH MASS SPECTROMETRY DETECTION FOR THE VOLATILE PROFILING OF VITIS VINIFERA CV. CARMÉNÈRE WINES

The volatile metabolome of Vitis vinifera C. V. Carménère wines, a unique Chilean winegrape variety, was characterized in this work. After solvent extraction with dichloromethane (LLE) or head space solid phase microextraction (HS-SPME), the resulting volatile compounds were analyzed by gas chromato...
