The flavanol compounds, mainly catechin, epicatechin and
procyanidins, are an important group of flavonoids considering
their high antioxidant capacity and sensory properties. The results
in Table 3 show that the epicatechin content is higher than that of
catechin in all wines, and the flavanols content was significantly
lower in CSV30, CSV40 and MV40 than in the control samples. The
involvement of catechins and epicatechins in the formation of
proanthocyanidins may explain the lower amount of these compounds
in the CSV30, CSV40 and MV40 wines (Figueiredo-Gonzalez
et al., 2013).
