What is Sodium aluminum phosphate?

Sodium aluminum phosphate is a chemical compound used primarily as a leavening agent in baked goods. It is made by combining sodium hydroxide, aluminum hydroxide, and phosphoric acid.

In food products, sodium aluminum phosphate helps doughs and batters rise evenly and maintain a consistent texture. Some health concerns have been raised due to its aluminum content, as excessive aluminum intake may be linked to neurotoxicity, but the evidence is not conclusive.

When you see sodium aluminum phosphate on a label, it's typically functioning to improve texture and leavening in the product, especially in baked goods like cakes and pastries.

Commonly found in: baked goods, cakes, pastries, muffins, biscuits, pancakes
