Résumé

Analysis of the volatile components of the white truffle (collected in central Italy) by purge and trap methods, showed the important contribution of 2,4-dithiapentane to the aroma. Tubers were stored at either 0 or 25 deg C. Aroma degradation showed great dependence on the storage conditions. At 0 deg C, there was only a slow decrease in 2,4-dithiapentane concentration, and amyl alcohols were released. At room temperature, the conversion of 2,4-dithiapentane into dimethyl disulphide was a more important factor influencing flavour.
