What it is

Sodium aluminum phosphate is a white powder made from aluminum phosphate and sodium hydroxide. It is often produced by reacting aluminum hydroxide with phosphoric acid, then neutralizing with a sodium compound. It is used as a food additive.

Why it's used

Manufacturers add sodium aluminum phosphate to foods as a leavening agent, meaning it helps doughs and batters rise. It works with baking soda to produce carbon dioxide gas, creating a lighter texture. It is commonly found in baked goods like cakes and cupcakes, as well as frozen appetizers.

Health notes

Sodium aluminum phosphate is generally recognized as safe (GRAS) by the FDA for use in food. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated it and established an acceptable daily intake. Evidence does not suggest adverse health effects at typical consumption levels.

Allergen info

Not a major allergen. It does not contain gluten.
