Is e339i vegan?

E339i is the European food additive code for monosodium phosphate, also known as sodium dihydrogen phosphate. It is an inorganic chemical compound synthesized through the chemical neutralization of phosphoric acid with a sodium source, typically sodium carbonate or sodium hydroxide. The primary raw material, phosphoric acid, is commercially derived from mined phosphate rock, which is a naturally occurring mineral.

In food manufacturing, e339i functions as an acidity regulator, emulsifying agent, and moisture stabilizer. It helps maintain product texture and prevent separation in items such as powdered drink mixes, breakfast cereals, baked goods, shelf-stable desserts, processed potato products, and various pre-packaged convenience foods.

This ingredient is vegan because its production relies strictly on mineral and synthetic sources. Animal products, derivatives, or animal-based processing aids are not used at any point during its synthesis or purification.
