Is INS 211 vegetarian?

INS 211 is made chemically, so it does not by itself make a food non-vegetarian. The green or brown mark on the pack is still the declaration to go by, because it covers every other ingredient too.

Counted from the 277 packs in Zabel's catalogue that list INS 211, 242 of which have a food category so far. Counted 4 Nov 2026.

What the evidence says

What does the evidence say about INS 211?

We grade an additive by the evidence about it, not by whether it sounds like a chemical, and we make no claim about whether a pack complies with FSSAI rules.

EFSA's 2016 re-evaluation kept a group ADI of 5 mg/kg body weight. Two specific issues: in a drink that also contains ascorbic acid (INS 300) and is stored warm, small amounts of benzene can form; and it was the preservative paired with the six colours in the 2007 Southampton hyperactivity trial.

Does Zabel mark INS 211 down?

Yes, by 6 points. The additives part of the score starts at 20, and each code takes off a fixed amount set by the strength of the evidence about it, not by the fact that it is an additive (method 1.0.0). Read the method.
