Abstract
Abstract A method for stabilizing tartar (i.e. inhibiting the precipitation of potassium bitartrate) in wine, grape must, or grape juice by electrodialyzing such liquids through membranes permeable to potassium and tartrate ions against a liquid whose osmotic pressure is substantially the same as that of the wine, must, or juice being electrodialyzed.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
144 words
A METHOD FOR THE STABILIZATION OF TARTAR IN WINE, GRAPE MUST, OR GRAPE JUICE BY THE REMOVAL THEREFROM OF SUFFICIENT POTASSIUM AND TARTRATE IONS INHIBIT THE PRECIPITATION OF POTASSIUM BITARTRATE, WHICH METHOD COMPRISES ELECTRODIALYZING SAID WINE, MUST, OR JUICE BETWEEN AN ANODE AND A CATHODE THROUGH A FIRST MEMBRANE PERMEABLE TO POTASSIUM IONS AND A SECOND MEMBRANE PERMEABLE TO TARTRATE IONS, IN EACH CASE AGAINST A RINSING LIQUID PRESENT ON THE SIDE OF SAID MEMBRANES OPPOSITE SAID WINE, MUST OR JUICE AND HAVING AN OSMOTIC PRESSURE SUBSTANTIALLY EQUAL TO THAT OF THE WINE, MUST OR JUICE BEING ELECTRODIALYZED, WHEREBY POTASSIUM IONS PASS FROM THE WINE, MUST, OR JUICE TOWARD THE CATHODE THROUGH SAID FIRST MEMBRANE INTO RINSING LIQUID SURROUNDING THE CATHODE AND TARTRATE IONS PASS FROM THE WINE, MUST, OR JUICE THROUGH SAID SECOND MEMBRANE TOWARD THE ANODE INTO RINSING LIQUID SURROUNDING THE ANODE.
Claim 2
Independent Claim
144 words
A METHOD FOR THE STABILIZATION OF TARTAR IN WINE, GRAPE MUST, OR GRAPE JUICE BY THE REMOVAL THEREFROM OF SUFFICIENT POTASSIUM AND TARTRATE IONS INHIBIT THE PRECIPITATION OF POTASSIUM BITARTRATE, WHICH METHOD COMPRISES ELECTRODIALYZING SAID WINE, MUST, OR JUICE BETWEEN AN ANODE AND A CATHODE THROUGH A FIRST MEMBRANE PERMEABLE TO POTASSIUM IONS AND A SECOND MEMBRANE PERMEABLE TO TARTRATE IONS, IN EACH CASE AGAINST A RINSING LIQUID PRESENT ON THE SIDE OF SAID MEMBRANES OPPOSITE SAID WINE, MUST OR JUICE AND HAVING AN OSMOTIC PRESSURE SUBSTANTIALLY EQUAL TO THAT OF THE WINE, MUST OR JUICE BEING ELECTRODIALYZED, WHEREBY POTASSIUM IONS PASS FROM THE WINE, MUST, OR JUICE TOWARD THE CATHODE THROUGH SAID FIRST MEMBRANE INTO RINSING LIQUID SURROUNDING THE CATHODE AND TARTRATE IONS PASS FROM THE WINE, MUST, OR JUICE THROUGH SAID SECOND MEMBRANE TOWARD THE ANODE INTO RINSING LIQUID SURROUNDING THE ANODE.
Claim 3
Dependent Claim
21 words
A method as in claim 1 wherein said wine, must, or juice is electrodialyzed against wine, grape must, or grape juice.
Claim 4
Dependent Claim
33 words
A method as in claim 1 wherein the wine, must, or juice subjected to electrodialysis is, after such treatment, employed as the liquid against which further wine, must, or juice is anodically electrodialyzed.
Claim 5
Dependent Claim
33 words
A method as in claim 1 wherein the wine, must, or juice subjected to electrodialysis is, after such treatment, employed as the liquid against which further wine, must, or juice is cathodically electrodialyzed.
Claim 6
Dependent Claim
28 words
A method as in claim 1 wherein said wine, must, or juice are anodically electrodialyzed against wine or must poorer in acid content than the material being electrodialyzed.
Claim 7
Dependent Claim
28 words
A method as in claim 1 wherein said wine, must, or juice are cathodically electrodialyzed against a wine poorer in potassium ion content than the material being electrodialyzed.
