Improved and more gentle process for extracting useful substances from grapes, grape must extracted therefrom and wine produced therefrom, as well as device for carrying out electroporation

摘要

A method for the sake of better and gentle release value surrounding components of grapes:consisting of the process steps:– a consisting of red and / or white grapes the mash obtained is kept at a temperature /, the above the freezing of the mash is and up to in the case of the conventional mash heating is adjusted in the conventional temperatures,– the mash is in front of the pressing process for the most recovery by a plant / a part of the plant and there to the pumped / flowed electroporation with pulsed electric fields to the irreversible opening of the cell walls of the biological cells of the wine berries skin is admitted to its pulse duration in the range of 0,5 – 3 μs is,– the mash during electroporation is subjected to such high field strengths in a pulsed manner that, on the one hand, the potential difference at the 7 to 10 μm large cells of the berries skin at least 100 volts and on the other hand, the boundary surface of the streamer formation, which in the case of about 1 000 kv / cm, is not achieved,– the specific energy dose for the electroporation, in the case of a temperature of the mash..
