What it is

Calcium silicate is a synthetic compound made from calcium oxide and silicon dioxide. It is produced by reacting calcium hydroxide with silicon dioxide under controlled conditions. It appears as a fine, white powder.

Why it's used

Manufacturers add calcium silicate to dry food products to prevent clumping and caking, ensuring a free-flowing texture. It acts as an anti-caking agent, absorbing moisture and keeping particles separate. It is commonly found in powdered seasonings, salts, spices, and baking mixes.

Health notes

In the U.S., calcium silicate is Generally Recognized As Safe (GRAS) by the FDA for use as an anti-caking agent. International bodies like JECFA and EFSA have also evaluated its safety. At typical consumption levels, it is not associated with adverse health effects. There are no widespread controversies regarding its use.

Allergen info

Calcium silicate is not derived from any of the nine FDA major allergens. It does not contain gluten.
