Headspace solid-phase microextraction for the determination of volatile organic sulphur and selenium compounds in beers, wines and spirits using gas chromatography and atomic emission detection.

11 Aug 2009 A rapid and solvent-free method for the determination of eight volatile organic sulphur and two selenium compounds in different beverage samples using headspace solid-phase microextraction and gas chromatography with atomic emission detection has ... Read more...

Changes in antioxidant endogenous enzymes (activity and gene expression levels) after repeated red wine intake.

10 Aug 2009 The antioxidant properties of wine have been largely related to the reactive oxygen species (ROS) scavenging ability of phenolic compounds. Polyphenolic compounds are hardly absorbed and quickly transformed into metabolites. Their antioxidant ... Read more...

Application of amperometric biosensors for analysis of ethanol, glucose, and lactate in wine.

10 Aug 2009 This article presents the application of amperometric biosensors based on platinum printed electrodes SensLab and immobilized enzymes, alcohol oxidase, glucose oxidase, and lactate oxidase, for wine analysis. Created devices demonstrate linear ... Read more...
