What it is

Calcium sulfate is a mineral compound that occurs naturally in rocks and minerals. It can also be produced industrially by reacting calcium carbonate with sulfuric acid. It is commonly used as a food additive.

Why it's used

Manufacturers add calcium sulfate to foods to prevent caking, meaning it helps keep powders from clumping together. It is often found in dry mixes like cheese blends, spice mixes, and baked goods.

Health notes

In the US, calcium sulfate is generally recognized as safe (GRAS) by the FDA for use as a food additive. It is a source of calcium and sulfate, which are naturally present in the body. International bodies like JECFA and EFSA have evaluated calcium sulfate and have not set a numerical limit for its acceptable daily intake. There are no widespread health concerns associated with its typical use in food.

Allergen info

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