FIELD: chemistry.
SUBSTANCE: wine is subjected to electrodialysis by passing it through processing chambers of an electrodialysis apparatus with electrodes. The processing chambers are bordered with alternating anion- and cation-selective membranes of the MA-40 and MK-40 type. Electrodialysis is carried out at current density of 60 to 80 A/m2 for 7 to 8 minutes. The electrolyte used in concentration chambers is a solution of potassium bitartrate with concentration of 4.5 to 5%.
EFFECT: possibility of preventing colloidal protein-phenol wine turbidity, reducing processing expenses by 2,5 to 3 times and enhancing its organoleptic properties.
