Abstract
Abstract
The results of study of phenolic composition, antioxidant activity and oxidation state of phenolic substances of white and red table wine materials were presented. Close correlational between the antioxidant activity of white table wine materials, the oxidation parameter of phenolic composition and the content of monomeric, oligomeric and polymeric forms of phenolic compounds were established., The correlation between antioxidant activity and oxidation parameter of phenolic substances has not been established for red wine materials. Direct effect of the oxidation state of phenolic substances in white table wine materials on their antioxidant activity was shown. The oxidation parameter of phenolic substances can be used as a criterion of assessing the antioxidant properties of white table wine materials and wines. The method of potentiometric titration may be recommended for use in processing, training and experimental analytical laboratories to assess the antioxidant activity of white table wine materials and wines.
