Abstract
This thesis has focused on the recovery of phenolic compounds from winery by-products and their use in food. In particular, we studied the lignocellulosic fractionation of grape stalks for the recovery of hemicelluloses, cellulose, lignin and antioxidants through a process of auto-hydrolysis. We also studied the influence of variety on the antioxidants extraction from Barbera, Pinot Noir and Nebbiolo grape marc. Finally, a freeze-dried extract from Barbera grape marc was used to improve the shelf-life of hazelnut paste evaluating the oxidation kinetics.
