Determination of carbonyl compounds in wine.Peer-reviewed article

O. PETROVÁ, G. JANÍČEK, J. DAVÍDEK

The article deals with a polarographic method which has been developed for determining carbonyl compounds in wine. The method is based on the reduction of semicarbazones. The results of ten analyses covering ten different sorts of wine fit very well the results of iodometric analyses. The method enables to determine all volatile carbonyl substances which are shown as acetaldehyde within 45 minutes. The described method is reasonably accurate and can be recommended for routine analyses.
