Flagged additives

• Ammonia caramel — Caramel colour class III; may contain 4-methylimidazole (4-MEI), an animal carcinogen.
• Butylated hydroxyanisole (BHA) — Antioxidant; classified as possibly carcinogenic to humans (animal forestomach tumours).
• Butylated hydroxytoluene (BHT) — Antioxidant; animal-study tumour/endocrine signals; structurally related to BHA.
• Monosodium glutamate (MSG) — Flavour enhancer; self-reported intolerance ('MSG symptom complex'); EFSA flagged exposure above the group ADI.
• Potassium phosphates — Inorganic phosphate additives are highly bioavailable; high additive-phosphate intake is associated with increased cardiovascular and kidney burden, particularly in chronic kidney disease.
• Diphosphates — Inorganic phosphate additives are highly bioavailable; high additive-phosphate intake is associated with increased cardiovascular and kidney burden, particularly in chronic kidney disease.
• Triphosphates — Inorganic phosphate additives are highly bioavailable; high additive-phosphate intake is associated with increased cardiovascular and kidney burden, particularly in chronic kidney disease.
• Disodium 5'-ribonucleotides — Ribonucleotide flavour enhancer typically used together with monosodium glutamate (E621); may contribute to symptoms reported by glutamate-sensitive individuals.
