الإجراء التجريبي

A hydrated gel of tricalcium phosphate is prepared by slowly adding a solution of calcium chloride (3.6% by weight) to a solution of trisodium phosphate (3.6% by weight) and reacted for 30 minutes. The pH of the reaction mixture was above 9.5. A translucent, hydrated precipitate of tricalcium phosphate is formed, which is concentrated by centrifugation. The concentrated gel is then washed twice with an equal weight of water, and again concentrated each time by centrifugation to a solids level of 6% by weight. The 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 7% by weight and a pH of 7.0±0.05. The gel was added in an amount sufficient to provide a calcium level of 2.7% by weight of the protein solids on a dry basis and the fortified slurry was allowed to equilibrate for 1 hour. The mineral fortified slurry is then spray-dried to a moisture level of less then 5% by weight.
