Is e535 vegan?

E535 is the E-number for sodium ferrocyanide, an inorganic compound commonly used as an anti-caking agent in food products. It is primarily added to table salt, sea salt, and various powdered seasoning blends to prevent moisture absorption and stop granular ingredients from clumping together during storage.

This additive is manufactured synthetically through chemical processes rather than extracted from biological matter. It is typically produced by reacting sodium cyanide with ferrous chloride or by treating calcium ferrocyanide with sodium carbonate. The precursor raw materials are obtained from mineral and industrial chemical sources, requiring no animal inputs or animal-derived processing aids during synthesis.

E535 is vegan because it is entirely synthetic and mineral in origin. No animal tissues, secretions, or animal-derived byproducts are utilized in its formulation or manufacture, making products containing this additive suitable for a vegan diet.
