This voltammetric methodology was successfully applied to DIM determination in fresh grapes and red wine samples, with recovery values of 101.0 +/- 12.1% and 105.1 +/- 10.8% (95% confidence interval). Based on quantum-chemical studies and the data obtained by gas chromatography-mass spectrometry (GC-MS), it can be concluded that the site of oxidation of DIM is the non-aromatic double bond, and that the DIM electrooxidation reaction forms the (4-chlorophenyl)-(3,4-dimethoxyphenyl)methanone as a major product.
