Aluminum Ammonium Sulfate

Aluminum ammonium sulfate is a type of aluminum salt. It is a white crystalline powder that is soluble in water. It is produced by combining aluminum sulfate with ammonium sulfate.

This ingredient is often used as a leavening agent in baked goods, particularly in cookie and biscuit mixes. It helps dough rise and creates a lighter texture. It is also used in some processed foods as an acidity regulator.

Aluminum ammonium sulfate is generally recognized as safe (GRAS) by the FDA for use in food. Regulatory bodies like JECFA have evaluated aluminum compounds, but specific evaluations for aluminum ammonium sulfate may vary. While aluminum is present in many foods and can be absorbed by the body, the levels typically consumed from food sources are not considered a health concern for most people.
