What it is

Sodium aluminum sulfate is a white crystalline powder. It is a salt made from aluminum and sulfuric acid. It is used as a leavening agent in baking.

Why it's used

Sodium aluminum sulfate is used as a leavening agent in baked goods like cakes, cupcakes, and pies. It reacts with baking soda to produce carbon dioxide gas, which causes doughs and batters to rise and become light and fluffy. It is often used in combination with other leavening agents.

Health notes

Sodium aluminum sulfate is generally recognized as safe (GRAS) by the FDA for use in food. It has been evaluated by international bodies like JECFA, which has established acceptable daily intake levels. While aluminum-containing compounds are widely consumed, some research has explored potential links between high aluminum intake and health outcomes, though evidence at typical dietary levels is mixed and not conclusive. The FDA continues to monitor scientific findings.
