Ph.D. student in food science and technologies
Application of chemical-physical and mechanical tests for the definition of wine grape quality:
• Evaluation of the importance of the grape characteristics for the appraisal of the grape oenological potential and
the prediction of the resulting wine quality.
• Appraisal of grape ripeness through phenolic composition and texture indices.
• Definition of grape texture indices, the methods applied to measure them and evaluation of their importance in
winemaking.
