Low sodium salt substitute with potassium chloride
Making a salt substitute includes forming a salt substitute precursor, providing the salt substitute precursor to a centrifuge, and centrifuging the salt substitute precursor to yield a salt substitute in the form of a solid and a centrate. The salt substitute precursor includes water, a chloride salt, a food grade acid, and an anticaking agent. The chloride salt includes potassium chloride. A pH of the salt substitute precursor is between 2 and 4, and the salt substitute precursor is a saturated or supersaturated solution, a suspension, or a slurry. The salt substitute includes a chloride salt, a food grade acid, and an anticaking agent. The salt substitute includes potassium chloride and is in the form of a crystalline solid including at least 95 wt % of the chloride salt, up to 1 wt % of the food grade acid, and up to 1 wt % of the anticaking agent.
1. A salt substitute precursor comprising:
water;
a chloride salt, wherein the chloride salt comprises potassium chloride;
a food grade acid; and
an anticaking agent,
wherein a pH of the salt substitute precursor is between 2 and 4, wherein the salt substitute precursor is free of a carrier, and the salt substitute precursor is a saturated or supersaturated solution, a suspension, or a slurry.
2. The salt substitute precursor of claim 1 , wherein the food grade acid comprises at least one of acetic acid, ascorbic acid, benzoic acid, citric acid, succinic acid, fumaric acid, lactic acid, malic acid, tartaric acid, lemon juice, hydrochloric acid, and phosphoric acid.
3. The salt substitute precursor of claim 1 , wherein the anticaking agent comprises at least one of sodium aluminosilicate, sodium ferrocyanide, potassium ferrocyanide, calcium carbonate, magnesium carbonate, tricalcium phosphate, and silicon dioxide.
4. The salt substitute precursor of claim 1 , wherein the chloride salt further comprises sodium chloride.
5. The salt substitute precursor of claim 1 , wherein a pH of the salt substitute precursor is between 3 and 4.

9. The salt substitute precursor of claim 8 , wherein the water comprises less than 50 wt % of the salt substitute precursor.
10. The salt substitute precursor of claim 9 , wherein the water comprises less than 25 wt % of the salt substitute precursor.
11. A method of making a salt substitute, the method comprising:
forming a salt substitute precursor comprising a mixture of:
water;
a chloride salt, wherein the chloride salt comprises potassium chloride;
a food grade acid; and
an anticaking agent,
wherein a pH of the salt substitute precursor is between 2 and 4, wherein the salt substitute precursor is free of a carrier, and the salt substitute precursor is a saturated or supersaturated solution, a suspension, or a slurry, providing the salt substitute precursor to a centrifuge; and
centrifuging the salt substitute precursor to yield a salt substitute in the form of a solid and a centrate.
12. The method of claim 11 , wherein a temperature of the salt substitute precursor provided to the centrifuge is less than 240° F.
13. The method of claim 11 , further comprising washing the salt substitute with the centrate.
14. The method of claim 11 , wherein the chloride salt further comprises sodium chloride, and the salt substitute is in the form of a combined crystalline solid comprising particles, wherein each particle of the combined crystalline solid comprises a region consisting essentially of potassium chloride in direct contact with a region consisting essentially of sodium chloride.
