実験手順

Alternatively, the phytic hexa-citrate compound was produced by the following method: First, 0.33 kg of calcium carbonate was slowly added, in increments of 0.1 kg, to 0.87 kg of phytic acid liquid. The mixture was heated and refluxed for about one hour at about 90° C. The two solids were separated and filtered. The white solid, which was calcium phytate, was collected. About 1 kg of the calcium phytate was dissolved into 2.0 liters of water and heated to about 89° C. for about 10-15 minutes until calcium phytate was completely dissolved in the water solution. About 0.9 kg of citric acid was then added to and stirred in the calcium phytate soluttion until the citric acid was completely dissolved. The heat source was removed and the resulting mixture was left sat at no more than 40° C. or in a refrigerated environment at a temperature of about 5-10° C. to allow the newly formed phytic hexa-citrate to crystallize for approximately 6 to 8 hours or until crystallization has ceased. The mixture was allowed to dry out at room temperature until no liquid was visible. The crystals were spread in a drying pan for approximately 24 hours at a temperature of no more than 40° C., which yielded approximately 1.2 kg of hexa-citrated phytate.
