Sodium Aluminum Phosphate (CAS 7785-88-8) is an acidic phosphate salt that appears as a white, odorless powder insoluble in water, reacts with bases to release gas slowly for dough stability, and is used in baking powders, processed cheese, potato products, seafood canning and self-rising flour mixes. It provides slow gas release for dough stability, sourced synthetically with purity verified by industry phosphates and EFSA food additive approvals.
