E541 Sodium aluminium phosphate is an inorganic phosphate-based compound made from sodium, aluminium, and phosphate groups, used mainly as a leavening acid and stabilizing agent in baked goods and processed foods, where it reacts with alkaline components (such as baking soda) to release carbon dioxide gas, helping dough rise and creating a light, porous texture in baked products.
E541 Sodium aluminium phosphate belongs to the group of aluminium-containing phosphates that are widely used in controlled food processing systems.
This improves dough aeration and baking consistency.
E541 Sodium aluminium phosphate consists of a network of aluminium and phosphate units balanced by sodium ions, and it functions as a slow-reacting acid in baking systems, meaning it releases acid gradually during heating, allowing controlled gas formation rather than rapid or premature reactions.

E541 Sodium aluminium phosphate are sodium salts of aluminium phosphates.
They are inorganic and most commonly have the formulas NaH14Al3(PO4)8·4H2O and Na3H15Al2(PO4)8.
These materials are prepared by combining alumina, phosphoric acid, and sodium hydroxide.
In addition to the usual hydrate, an anhydrous SAlP is also known, Na3H15Al2(PO4)8 (CAS#10279-59-1), referred to as 8:2:3, reflecting the ratio of phosphate to aluminium to sodium.
Additionally an SAlP of ill-defined stoichiometry is used (NaxAly(PO4)z (CAS# 7785-88-8).
E541 Sodium aluminium phosphate is also important in industrial baking process engineering, where it is selected specifically because it provides a predictable “delayed reaction profile,” meaning it does not fully react until it reaches baking temperatures, which allows manufacturers to control when gas formation begins and how quickly the dough expands inside ovens.
This timing control is especially important for large-scale, high-speed bakery production lines.
E541 Sodium aluminium phosphate improves baking precision and production consistency.
E541 Sodium aluminium phosphate is often used together with other leavening agents to balance reaction speed, because different acids in baking powders can react too quickly or too slowly, while sodium aluminium phosphate helps stabilize the overall gas release curve for a more uniform final structure.
This is essential for achieving consistent crumb texture in mass-produced baked goods.
