Application of isolatachophoresis for the determination of compounds binding sulphur dioxide in wine.Peer-reviewed article

J. KOVÁČ, J. FARKAŠ, M. SVOBODA

The application of isotachphoresis for the determination of acetaldehyde, pyruvic acid and 2-oxoglutaric acid in wine is described. These compounds react with sulphur dioxide. The fixed SO₂ is no more active. The method is quick, accurate enough and permits the evaluation of the formation of SO₂-inactive compounds in production plants.
