Tricalcium Phosphate As Anti-caking Agent

Tricalcium phosphate is a calcium salt of phosphoric acid. It is typically made from calcium carbonate (like limestone) and phosphoric acid. It is a white powder that is insoluble in water.

Manufacturers use tricalcium phosphate as an anti-caking agent to prevent powdered foods from clumping together. It helps keep ingredients free-flowing and easy to mix. It is commonly found in powdered drink mixes, seasoning blends, and grated cheeses.

In the U.S., tricalcium phosphate is Generally Recognized As Safe (GRAS) by the FDA for use as an anti-caking agent and nutrient supplement. It is a source of calcium and phosphorus. International bodies like JECFA and EFSA have evaluated tricalcium phosphate. At typical dietary levels, it is not associated with adverse health effects.
