Abstract
The invention relates to a method for extracting molecules of interest from a plant matrix, the method including the following steps: electrically processing the plant matrix by means of pulsed power; diffusing the molecules of interest from the processed plant matrix in a hydroalcoholic solvent and/or a solvent including ethyl acetate; and recovering the molecules of interest that were diffused.
Claims23
A method comprising:
- electrical treatment by pulsed power of the plant matrix made up of all or part of grape pomace;
- diffusing molecules of interest of the treated plant matrix in a solvent comprising a mixture of alcohol and ethyl acetate;
- and
- recovering the molecules of interest having diffused.
A method comprising
- electrical treatment by pulsed power of the plant matrix made up of all or part of grape pomace;
- diffusing polyphenols of the treated plant matrix in a solvent comprising a mixture of alcohol and ethyl acetate;
- recovering the polyphenols having diffused;
- and
- mixing the polyphenols with wine.
A method comprising:
- electrical treatment by pulsed power of the plant matrix made up of all or part of grape pomace;
- diffusing molecules of interest of the treated plant matrix in a solvent comprising a mixture of alcohol and ethyl acetate;
- and
- recovering the molecules of interest having diffused,
- wherein the electrical treatment is carried out by the application of high-voltage electrical discharges.
A method comprising:
- electrical treatment by pulsed power of the plant matrix made up of all or part of grape pomace;
- diffusing molecules of interest of the treated plant matrix in a solvent comprising a mixture of alcohol and ethyl acetate;
- and
- recovering the molecules of interest having diffused,
- wherein the electrical treatment is carried out by the application of pulsed electric fields and the intensity of the pulsed electric field is between 15 and 25 kV.cm−1.
A method comprising:
- electrical treatment by pulsed power of the plant matrix made up of all or part of grape pomace;
- diffusing molecules of interest of the treated plant matrix in a hydroalcoholic solvent or a solvent composed of ethyl acetate, wherein the solvent includes a mixture of alcohol and mixture of alcohol and ethyl acetate;
- and
- recovering the molecules of interest having diffused,
- wherein the electrical treatment is carried out by the application of pulsed electric fields and the intensity of the pulsed electric field is between 15 and 25 kV.cm−1, and wherein the electrical treatment and diffusion steps are carried out with a continuous flow of solvent in a treatment tube.
