Nut-Free Ingredients — Do Any E-Numbers Contain Nuts?
Straightforwardly: no E-number is made from tree nuts. Food additives are not a nut-allergy risk — but the label around them can be.
Tree nuts are one of the 14 declared allergens, so any deliberate nut ingredient must be named on the label. The nut risks in processed food come from actual nut ingredients, nut oils in flavourings, and 'may contain' cross-contamination — not from the additive system. If an E-number appears in a product with no nut declaration and no may-contain warning, the additive itself is not a nut concern.
One adjacent note: some natural flavourings can be derived from nut sources, and flavourings are labelled generically — if you have a severe nut allergy, manufacturer confirmation on flavourings is the sensible check.
