Is e504i vegan?

E504i is the European food additive code for magnesium carbonate, an inorganic mineral compound used primarily as an anti-caking agent and acidity regulator. It is commercially produced either by mining natural mineral ores such as magnesite and dolomite or through chemical synthesis by reacting soluble magnesium salts with sodium carbonate. Food manufacturers commonly add it to table salt, baking powder, flour, confectionery, processed cheeses, and powdered drink mixes to keep dry ingredients free-flowing and to control acidity levels.

This ingredient is classified as vegan because it is derived exclusively from mineral and synthetic sources. Animal inputs, tissues, and byproducts are not utilized at any stage in the mining, chemical precipitation, or refining processes for magnesium carbonate. Consequently, any food product containing E504i is suitable for a vegan diet.
