Phosphoric Acid → Tricalcium Phosphate

Participants

Reaction Steps

A hydrated gel of tricalcium phosphate is prepared by slowly adding a solution of phosphoric acid (85% by weight) to a solution of calcium hydroxide (2.0% by weight) and reacted for 30 minutes. A translucent, hydrated precipitate of tricalcium phosphate is formed, which is concentrated by centrifugation. The concentrated gel of tricalcium phosphate is then added to the slurry of soy isolate. The slurry, following addition of the gel has a solids level of 14% by weight and a pH of 7.0±0.05. The gel is added in an amount sufficient to provide a calcium level of 2.6% by weight of the protein solids on a dry basis and the fortified slurry was allowed to equilibrate for 1 hour.
