What it is

Calcium hydroxide is a mineral compound that is a white, powdery substance. It is made by reacting calcium oxide (quicklime) with water. It is also known as slaked lime.

Why it's used

Manufacturers add calcium hydroxide to foods as an acidity regulator, firming agent, and dough conditioner. It is commonly found in corn masa for tortillas and tamales, processed cheeses, and some beverages.

Health notes

In the U.S., calcium hydroxide is Generally Recognized As Safe (GRAS) by the FDA for use in food. It is used in small amounts and is not associated with adverse health effects at typical consumption levels. International bodies like JECFA and EFSA have evaluated calcium hydroxide, but no specific numeric limits are set. Evidence does not suggest significant health concerns.

Allergen info

Calcium hydroxide is a mineral and is not derived from any of the nine FDA major allergens. It does not contain gluten.
