Introduction. Pescabivona isthe name of an autochthonous peach [Prunus persica (L.)Batch] population of the central west of Sicily. In a previous work,this fruit was submitted to chemical analysis, while in this paper,sensory evaluation is considered. Materials and methods.Samples of four Pescabivona landraces were harvestedthroughout the harvest season. A trained panel outlined the sensoryprofiles and the data were processed by ANOVA and Principal ComponentAnalysis (PCA). A correlation between sensory analysis and instrumentaldata was finally carried out. Results and discussion.The results demonstrated a high standard of quality for the fourlandraces studied, with some differences in aroma intensity and insome other parameters, with sweetness and aroma being highly correlatedwith overall liking. PCA did not clearly separate the differentlandraces as they have the same origin. Some correlations betweensensory analysis and instrumental data were verified. The sensory likingwas correlated with the main ripeness parameters, as well as with thepulp firmness. Conclusion. The data obtained contribute tooutlining a complete fruit profile for product comparison and shelf-lifemonitoring. As previously verified for chemical parameters, thesensory evaluation indicates a substantial similarity among the landraces.The good agreement between sensory evaluation and composition makessensory analysis a precious tool to assess quality of Pescabivonalandraces.
