What it is

Calcium silicate is a synthetic compound made from calcium oxide and silicon dioxide. It is a fine, white powder that is insoluble in water. It is produced by reacting calcium compounds with silica under controlled conditions.

Why it's used

Manufacturers add calcium silicate to foods as an anti-caking agent. It helps prevent powdered or granulated ingredients from clumping together, ensuring a free-flowing product. It is commonly found in dry mixes, spices, and powdered beverages.

Health notes

In the United States, calcium silicate is Generally Recognized As Safe (GRAS) by the FDA for use as an anti-caking agent. Regulatory bodies like JECFA and EFSA have evaluated its safety and have not set a numeric limit for intake. At typical levels used in food, it is not expected to cause adverse health effects.
