This video explains how high voltage electric pulses can be used to improve the extraction of phenolic compounds in wine production. The process involves despatching the grapes, separating the grains from the raspons, and then propelling the mixture of hollejos and juice through a chamber with a linear flow where electric pulses are applied.

• 00:00:00 This video explains the technology behind high voltage electric pulses, commonly referred to as "pez." This new process for food processing involves intermittent application of fields of high and short-intensity electric currents of the order of microseconds to a material placed between two electrodes. This treatment results in the phenomenon called electroporation, which is the formation of pores in cellular membranes. This transformation can be temporary or permanent, with little or no increase in temperature. Electroporation has two potential applications in the food industry: the inactivation of microorganisms at temperatures that do not affect food properties and the improvement of extractive properties of ingredients that are of interest to the food industry. This video presents a potential application of high voltage electric pulses for the improvement of extraction of phenolic compounds in wine production. The process is as follows: first, the grapes are despached, separating the grains from the raspons. The grains and part of the extracted juice are collected in a tolva and propelled with a peristaltic pump to a chamber treated with high voltage electric pulses. The mixture of hollejos and juice passes through a chamber with a linear flow where electric pulses are applied to a river that varies between 100 and 3,000 kilograms per second. Once treated,
