Patent ID: 7641932

Claim:
A phosphate salt mixture for use in the manufacture of a food grade brine for the food industry comprising: a) 60 to 85 weight % of a clear soluble potassiumtripolyphosphate (KTPP) with a P205 content of 46.0 weight % to 47.0 weight % and a K 2 O/P 2 O 5 mole ratio of 1.7 to 1.78, b) 14 to 39 weight-% sodiumpolyphosphate, with 60-71.5 weight-% P 2 O 5 c) 1 to 5 weight % of M x H 3-x PO 4 , with M=Na, K and x=1,2,3 and/or M x H 4-x P 2 O 7 , in which M=Na, and x=2,3,4 and when M=K then x=4; wherein the phosphate mixture exhibits, in water, a pH value of 8 to 10 and exhibits a turbidity, in water and brines, of <5 TE/F.
