What it is

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

Why it's used

Manufacturers add tricalcium phosphate to powdered foods to prevent clumping and ensure a free-flowing texture. It acts as an anticaking agent, absorbing moisture and keeping particles separate. It is commonly found in seasoning mixes, salt, powdered sugar, and some dairy-free powdered products.

Health notes

In the U.S., tricalcium phosphate is generally recognized as safe (GRAS) by the FDA for use as an anticaking agent and nutrient supplement. It is a source of calcium and phosphorus. International bodies like JECFA and EFSA have evaluated its safety. Evidence does not suggest adverse health effects from typical dietary intake.

Allergen info

Tricalcium phosphate is not derived from any of the nine major allergens. It does not contain gluten.
