Electrical, mechanical, and chemical effects of high-voltage electrical discharges on the polyphenol extraction from vine shoots

This study gives significant information about the action mechanisms of high voltage electrical discharge treatment presenting relevant data for the design of the process. It shows the effectiveness of electrical discharges for the intensification of the extraction of bioactive molecules (polyphenols) from a specific byproduct (vine shoots). The paper also presents an energy-saving extraction process, relevant for industrial application, since no organic solvents were used. Process duration and temperature were also reduced.
