Is e230 vegan?

E230 is the E-number for biphenyl, also known as diphenyl, a synthetic aromatic hydrocarbon used primarily as an agricultural preservative and fungicide. It is manufactured industrially through chemical synthesis, typically via the thermal dealkylation of toluene or the oxidative dehydrogenation of benzene derived from petroleum feedstocks. In food distribution, it is applied directly to the packaging materials or rinds of citrus fruits, such as oranges, lemons, and grapefruits, to inhibit fungal growth and decay during transport and storage.

E230 is vegan because it is an entirely synthetic chemical derived from mineral and petroleum sources, involving no animal inputs at any stage of production. Neither the raw materials nor the chemical synthesis pathways utilize animal tissues, fats, or processing aids. Although its approval as a direct food additive has been phased out or restricted in several jurisdictions, any presence of E230 on fruit coatings or agricultural packaging remains strictly non-animal in origin.
