Consumer Advice
Aluminium potassium sulfate (potassium alum) is one of the most common alums, traditionally used as a raising agent in fried dough snacks such as Chinese youtiao, and as a firming agent for jellyfish and other aquatic products. Because high aluminium intake is linked to nervous-system and bone-health concerns, China restricts aluminium additives in wheat products with residue limits. It is best to limit fried dough and pickled jellyfish and to read labels.
