Additives (5)
This label lists 2 acidity regulators, 2 sweeteners and 1 colour.
E338
Phosphoric acid
Acidity regulator
What it is. A strong food acid that gives cola drinks their sharpness.
Why it is used. Used in colas and some processed foods to control acidity.
What the evidence says. EFSA set a group acceptable daily intake for phosphates in 2019 and noted that high consumers, particularly children, can exceed it once all sources are counted. The concern is total phosphate intake across the diet rather than one drink, and it matters most for people with reduced kidney function.
Permitted with maximum levels, under a group limit shared with the other phosphate additives.
Assessed against EFSA. Full entry for E338
E950
Acesulfame K
Artificial sweetener
What it is. A calorie free intense sweetener, often blended with other sweeteners to round out taste.
Why it is used. Used in diet drinks, dairy and confectionery.
What the evidence says. Long treated as safe by regulators. Some recent research on sweeteners and the gut microbiome is ongoing, but nothing has changed the official safety position.
Permitted with an acceptable daily intake in all three regions.
Assessed against EFSA, JECFA. Full entry for E950
E951
Aspartame
Artificial sweetener
What it is. An intense sweetener around 200 times sweeter than sugar, used in tiny amounts.
Why it is used. Sweetens diet drinks, sugar free gum and low calorie desserts.
What the evidence says. In 2023 IARC listed it as possibly carcinogenic, its weakest evidence tier. At the same time the expert intake committee JECFA kept the safe daily limit unchanged, noting you would need a very high daily intake to approach it, roughly a dozen or more cans of diet drink a day for an adult. So headline scary, practically low concern for normal use.
Permitted with an acceptable daily intake. People with the condition PKU must avoid it, which is why packs carry a phenylalanine note.
Assessed against IARC, JECFA, EFSA. Full entry for E951

- E331 Sodium citrates acidity regulator
Names and jobs come from the register of additives permitted in Great Britain, which we have not finished transcribing: a code shown without a name is a gap in our coverage, not a finding that it is unapproved. Naming one is not grading it either. Full detail appears only where we have an assessment against a named authority, so all of this describes our coverage rather than these additives. Most are common and low concern.

As printed on the pack, in the producer's own order: ingredients are listed by weight, so what comes first is most of what is in it. E numbers link to their assessment where we have one.
