Aluminium Sulfate

Aluminum sulfate is a salt made from aluminum, sulfur, and oxygen. It is typically produced by reacting aluminum hydroxide or aluminum metal with sulfuric acid. It appears as a white crystalline solid or powder.

Manufacturers use aluminum sulfate as a leavening agent in baked goods like cakes and cupcakes, and in baking mixes. It helps dough rise and creates a lighter texture. It can also be used as a firming agent in some processed vegetables.

In the U.S., aluminum sulfate is Generally Recognized As Safe (GRAS) by the FDA for use as a food additive. International bodies like JECFA and EFSA have evaluated aluminum compounds, but specific evaluations for aluminum sulfate's use as a food additive and their conclusions are not detailed here. Concerns about aluminum intake often relate to its presence from various sources, including food additives, cookware, and water.
