dc.description.abstract | Wine contains polyphenols that are responsible for its quality. Moreover, phenolic compounds
have antioxidant properties and benefits on human health. Cyclic voltammetry
(CV) was the first electrochemical method used for polyphenols characterization
and determination of polyphenols content in wine products. Electrochemical behaviour
of standard solutions of phenolic compounds has been investigated and evaluated
the importance of the phenolic concentration and pH. The electrochemical parameters
extracted from the voltammograms have been correlated with the antioxidant potential
in wine products. In addition, CV allowed establishing differences in the antioxidant
activity of wines with different addition of grape seeds. In winemaking by-products,
different
Ipa and Q500 values were found depending on the state of maturation of the grape
pomace. On the other hand, the total flavonoids and phenolic acids contents were significantly
correlated to the electrochemical parameters. Differences for the electrochemical
parameters were found between by-products, being pomace and seeds which presented
the greatest values of Q500. Simple regression analyses showed that voltammetric parameters
are correlated to their values of lipid peroxidation inhibition by thiobarbituric
acid reactive substances method. Our results open the possibility of CV as a promising
technique to estimate the global antioxidant potential of wine products rich in phenolic
compounds. | es |
