PHENOLIC PROFILE IN SELECTED SICILIAN WINES PRODUCED BY DIFFERENT TECHNIQUES OF BREEDING AND CROPPING METHODS

The phenolic profiles of selected Sicilian wines, produced from grapes that differed from one another in techniques of breeding and cropping methods, were investigated. Phenolics were identified in Sicilian young red wines from autochthonous and allochthonous grapes by a rapid HPLC-DAD/MS method. The effect of cultivation techniques used in vineyard on the phenolic composition was confirmed. This study allowed verifying such dependence considering three techniques of breeding and two horticultural cropping methods. In order to detect tendencies in the analysed samples according to the phenolic compound contents, Principal Components Analysis (PCA) and Canonical Discriminant Analysis (CDA) were used.
