Abstract:
1. A granulation process for making calcium carbonate granulations that are compressible into calcium supplement tablets comprising the steps of mixing under high shear a USP or food grade calcium carbonate powder having a median particle size from about 15 μm to about 20 μm with maltodextrin having a dextrose equivalent (DE) of 9 to 12 and an amount of water comprising from about 5% to about 20% by weight based on the weight of calcium carbonate and drying the composition to achieve a water content of less than about 1% by weight, wherein the resulting calcium carbonate granulation are highly compactable and having a tap density from about 0.9 to about 2.0 g/cm 3 .
