Is e452i vegan?

E452i is the food additive code for sodium polyphosphate, which functions primarily as an emulsifier, stabilizer, and moisture retention agent. It is manufactured industrially by reacting phosphoric acid, derived from mined mineral phosphate rock, with sodium carbonate or sodium hydroxide. The resulting compound is heated to high temperatures to form polymerized phosphate chains, meaning its production relies entirely on inorganic mineral and chemical inputs.

Manufacturers add E452i to a variety of products, including plant-based milk alternatives, processed cheeses, baked goods, dessert mixes, canned soups, and soft drinks. It is commonly used to prevent the separation of liquids, improve the texture of processed foods, and bind water.

Sodium polyphosphate is classified as vegan because it is produced exclusively from mineral and synthetic sources. Animal-derived ingredients, tissues, and processing aids are not used at any point during its synthesis or refinement.
