Overview

E341I - Monocalcium phosphate

Monocalcium phosphate (E341i) is a calcium phosphate salt used mainly as a fast-acting leavening acid in baking. It helps doughs and batters rise, stabilizes acidity, and can add a small amount of calcium to foods. It is widely used in baking powder and self-rising flour.

E503I - Ammonium carbonate

Ammonium carbonate (E503i) is a classic leavening agent, often called baker’s ammonia. It releases gases during baking that puff and crisp thin, dry baked goods like crackers and cookies, without leaving a salty or soapy taste. It is part of the broader E503 group alongside ammonium hydrogen carbonate (E503ii), and is widely used in traditional European recipes for its clean, crisp lift.

Popular questions

Is monocalcium phosphate bad for you?
No—at typical food levels it’s considered safe (GRAS in the U.S. and authorized in the EU); concerns mainly arise with excessive phosphate intake or in people with kidney disease.
What does monocalcium phosphate do to your body?
It dissociates into calcium and phosphate ions, common nutrients involved in bone structure and cellular energy, and at normal intakes has no special effects beyond contributing small amounts of these minerals; very high phosphate intake can disrupt mineral balance, especially with kidney problems.
Is monocalcium phosphate dairy?
No—it's a mineral salt made from phosphate rock and calcium sources, not from milk, so it’s dairy‑free.
Is monocalcium phosphate vegan?
Yes—it's typically produced from mineral sources and contains no animal-derived ingredients; strict vegans may still confirm sourcing with the manufacturer.
What is monocalcium phosphate in food?
It’s a leavening acid used in baking powders to react with baking soda and release carbon dioxide so baked goods rise; it also helps regulate acidity and can add calcium.
