NEW RESEARCH ARTICLE: Phenolic characterization of aging wine lees: correlation with antioxidant activities

Aging wine lees are water-wastes produced during the wine aging inside wood barrels that can be considered as alternative sources of bioactive compounds. Phenolic characterization and antioxidant activity (AA) measurements of wines lees solid-liquid extracts have been undertaken on a dry extract (DE) basis. Solvents with different polarities (water, methanol, ethanol, two hydroalcoholic mixtures and […]

Supercritical Water Oxidation (SCWO) with hydrothermal flame sustained by disaccharides without using co-fuel

The High Pressure Process Group of the University of Valladolid has recently proved that hydrothermal flames can be sustained by supercritical water oxidation of disaccharides, thus opening the possibility of processing different waste effluent containing sugars or biopolymers using this technology. Using the Cooled Wall Reactor with a hydrothermal flame inside, developed by the High […]
