What it is

Acidic Calcium Sulfate is a salt made from calcium, sulfur, and oxygen. It is often produced by reacting calcium carbonate (like limestone) with sulfuric acid. It appears as a white crystalline powder.

Why it's used

Manufacturers use it as an acidulant and leavening agent in baked goods like croissants, muffins, and cakes. It helps create a lighter texture by reacting with baking soda to produce carbon dioxide gas. It can also be found in condiments like ketchup and mustard.

Health notes

In the US, Acidic Calcium Sulfate is generally recognized as safe (GRAS) by the FDA for use in food. Regulatory bodies like JECFA and EFSA have evaluated it. At typical consumption levels found in food, it is not associated with adverse health effects.

Allergen info

Not a major allergen. It does not contain gluten.
