E355 Adipic acid — is it halal?
Description
Adipic acid (E355) is a dicarboxylic acid used as an acidity regulator. The main industrial route oxidises cyclohexane (or hydrogenates phenol) to cyclohexanol / KA oil and then oxidises it with nitric acid over a copper–vanadium catalyst (c1, c2); the Chinese standard and 21 CFR describe only this route. The EU specification does not state the method. Patents also describe other chemical routes (c3)
