Consumer Advice
Aluminium sodium sulfate is an alum-type salt used as a raising agent to make fried dough, biscuits and other products light and crisp, and as a firming agent in pickles. Because of aluminium's potential health risks, many countries impose strict limits or bans on aluminium additives; China has strict aluminium residue rules for wheat-based products. It is wise to limit fried dough and puffed snacks and to check ingredient labels.
