Abstract
A beverage containing a mixed sodium potassium polyphosphate glass with a high potassium to sodium ratio and a low level of insoluble material is provided. The mixed sodium-potassium polyphosphate glass has the formula (K,Na)(n+2)O(PO3)n, and contains less than 10% by weight insoluble material. These materials are effective in controlling yeast, mold, and bacterial growth. The beverage comprises about 100 ppm to about 3000 ppm of a polyphosphate.
