Is e450i vegan?

E450i is the European food additive code for disodium diphosphate, also known as sodium acid pyrophosphate. It is an inorganic salt produced chemically from mineral sources. Industrial production involves neutralizing food-grade phosphoric acid, which is derived from mined phosphate rock, with sodium hydroxide or sodium carbonate. The resulting monosodium phosphate is then heated to high temperatures to trigger a dehydration reaction that yields disodium diphosphate.

Food manufacturers frequently list e450i in commercially prepared baked goods, refrigerated dough, self-rising flour, and chemical baking powders, where it functions as a slow-acting leavening acid. It is also added to processed potato products like frozen french fries to prevent discoloration, as well as to packaged puddings and various processed foods to stabilize moisture and texture.

e450i is vegan because it is derived entirely from mineral and synthetic raw materials. Animal-derived ingredients, animal fats, and bone-derived products are never utilized at any stage of its synthesis or refinement.
