Chemical characterization of different granulometric fractions of grape stalks waste

The chemical composition of grape stalks wastes from wine production was investigated after milling and separation in three different size material fractions. The chemical characterization included summative composition, total polyphenols, condensed tannins, lipophilic extractives ash composition, d...
