Tropical fruit scenting sulphur volatiles

Tropical Fruit Scenting Sulphur Volatiles (TFSV) in wine recent additional results in quantification and ranging in different varietal wines of Italy... 

The most important Tropical Fruit Scenting Sulphur Volatiles (TFSV) in wine are 3-mercaptohexan-l-ol (3-MH), 3-mercaptohexanol acetate (3-MFLA) and 4-methyl-4-mercaptopentan-2-one (4-MPP). The main problem for quantification of TFSV is their possible very low concentration which may be only a few ng/L. Therefore, only the use of selective isolation and pre-concentration steps allows this difficulty to be overcome. Another problem occurring in thiols analysis is their possible reactivity towards oxidation induced by the working conditions (Rapp et al., 1985) and/or by some components of the matrix in analysis (Murat et al., 2003 Blanchard et al., 2004).
