Abstract:

In order to shorten the aging time of red wine and improve its quality, high-voltage pulsed electric field was used to treat red wine. Compared with spontaneous aging, the evolution of proanthocyanidins was monitored by reversed-phase high performance liquid chromatography (RP-HPLC) coupled with UV-visible detector to evaluate the effect of high-voltage pulsed electric field on proanthocyanidins content in freshly brewed dry red wine. After the treatment of high-voltage pulsed electric field, the content, average polymerization degree and monomer composition of proanthocyanidins exhibited a significant change, which revealed the similar effect with the spontaneous aging of red wine in a bottle. During the treatment of electric field below 18 kV/cm, the aging effect of treated wine was more close to the spontaneous evolution of wine with increasing electric field intensity. However, the aging effect on red wine exhibited a decrease trend when the electric filed intensity was over 24 kV/cm. These investigations suggest that appropriate pulsed electric field treatment could accelerate the mature and aging of red wine and improve its quality.

Key words: freshly brewed dry red wine, pulsed electric field, proanthocyanidins
