1. A process for the preparation of an aqueous soluble ferric pyrophosphate concentrate solution, wherein the process comprises the steps of:

  • (a) forming an aqueous dispersion of insoluble ferric pyrophosphate by adding 0.1 to 5 weight/volume % of the insoluble ferric pyrophosphate to water,(b) adding 0.15 to 50 weight/volume % of trisodium citrate to the aqueous dispersion obtained from (a) to form an aqueous ferric pyrophosphate and trisodium citrate solution, and(c) boiling the resulting aqueous ferric pyrophosphate and trisodium citrate solution from step (b) by heating the aqueous ferric pyrophosphate and trisodium citrate solution at a temperature of 100 to 120°

    C. and a pH of between 4 to 8 for a time of 10 to 120 minutes until complete dissolution of ferric pyrophosphate occurs to thereby obtain an aqueous soluble ferric pyrophosphate concentrate solution.
