- The effect of the residues of two fungicides (mepanipyrim and fenhexamid) on the color and phenolic profile of Tempranillo and Graciano red wines has been studied. To evaluate possible modifications in color and phenolic composition of wines, control wines (not treated) and wines elaborated with spiked musts were analyzed. Thereby, changes in the color parameters of CIELab space were observed in the wines treated with mepanipyrim and also in Tempranillo wines treated with fenhexamid. In general, the anti-fungal substances had different effects depending on the cultivar and on the phenolic compound analyzed; being monomeric anthocyanins and flavan-3-ol monomers the compounds more affected by the presence of these fungicides.
