Abstract: Process for the protein stabilization of an oenological liquid, comprising a step of preparation of an oenological liquid (3) containing proteins, a step of application of at least one pulsed electric field to the oenological liquid (3), followed by a step of introducing at least one protease into the oenological liquid (3), a hydrolysis step, in which the protease catalyses the breakage of at least one peptide bond between the amino group and the carboxyl group of the proteins present in the oenological liquid (3), thereby forming compounds (7) containing the amino and/or carboxyl groups; such hydrolysis step transforms the oenological liquid (3) into a stabilised oenological liquid (5).

Abstract: Wine-making process comprising a first step of arranging “Acacia Verek” raw gum arabic and a second step of arranging a wine to be bottled, a step of dissolving the raw gum arabic in water in order to obtain raw gum arabic in solution with a concentration of gum arabic comprised between 5 and 50%, a step of filtering the raw gum arabic in solution by means of a tangential filter provided with synthetic membrane with nominal porosity comprised between 0.5 and 3 ?m in order to obtain filtered gum arabic in solution with a concentration of gum arabic comprised between 5 and 40%, a step of admixing the filtered gum arabic in solution in the wine to be bottled in order to obtain a wine to be bottled admixed with gum arabic, and finally a step of microfiltrating the wine to be bottled admixed with gum arabic.
