Aluminum Sulphate

Aluminum sulfate is a chemical compound that occurs naturally as the mineral alunogen. It is typically produced industrially by reacting aluminum hydroxide or aluminum metal with sulfuric acid. It appears as a white crystalline solid or powder.

In food, aluminum sulfate is primarily used as a leavening agent, reacting with baking soda to produce carbon dioxide gas, which causes baked goods to rise. It can also act as a firming agent and a pH control agent. It is commonly found in cakes, cupcakes, muffins, and other pastries.

Aluminum sulfate is generally recognized as safe (GRAS) by the FDA when used for its intended purpose in food. While the body can absorb small amounts of aluminum from food, most is not absorbed and is excreted. JECFA has evaluated aluminum sulfate and established an acceptable daily intake. Some studies have explored potential links between aluminum exposure and health conditions, but the evidence is not conclusive, and regulatory bodies continue to monitor research.
