DETERMINATION OF VOLATILE COMPOUNDS IN TXAKOLI WINE FROM BISCAY BY GAS-CHROMATOGRAPHY MASS-SPECTROMETRY

An analytical method combining a Soxhlet extraction and gas chromatogr aphy with mass spectrometric detection is proposed for the determinati on of volatile compounds in samples of Txakoli from Biscay (region loc ated in the north of Spain). The use of direct injection was compared with the results obtained from the organic extract. The extraction of the compounds from the matrix was performed with dichloromethane-hexan e (1:1, v/v). Both procedures were applied to the study of Txakoli var ieties of wine. (C) 1997 Elsevier Science B.V.
