Is e132 vegan?

E132 is a food additive commonly known as indigotine or indigo carmine, which is a synthetic blue coloring agent. It is commercially produced through the chemical synthesis and sulfonation of synthetic indigo, which is manufactured from petrochemical precursors. Food manufacturers use this artificial colorant to impart blue and violet hues to a wide variety of items, including confectionery, baked goods, soft drinks, ice cream, snack foods, and pharmaceutical coatings.

E132 is vegan because it is a completely synthetic substance that does not utilize animal sources. Unlike red colorants that can be derived from insects, indigotine relies strictly on synthetic organic chemistry for its production. Since no animal tissues, byproducts, or animal-derived processing aids are involved in its synthesis, E132 is suitable for individuals following a vegan diet.
