| Abstract: | The extraction of condensed tannins from grape pomace was examined using a mixture water-sodium hydroxide at 120 °C. The extracts were characterized by solution 13C NMR and have showed characteristic consistent with that of condensed tannins with dominant procyanidin units. The tannin fractions reactivity toward formaldehyde was studied by gel time analysis and thermomechanical analysis in bending. It has been demonstrated that the extracts obtained by using 10% of NaOH (w/w) displayed promising properties for adhesive applications. |
