What Calcium ferrocyanide does to a score

A packaged food starts with 33 points for what is in its ingredient list. Calcium ferrocyanide takes no points off a product's score. Scan the pack in Sito and the score you get is the one for your own child's age, with this additive named in the reasons. How we score has the whole method.

What the sources found

Every classification in our table comes from the citations below, and nothing else. They are quoted as the source wrote them.

EFSA Journal 2018;16(7):5374 — doi:10.2903/j.efsa.2018.5374
Group ADI 0.03 mg ferrocyanide ion/kg bw/day for E 535–538; exposure in children up to 0.009 (MPL) and ~0.003 (refined) mg/kg bw/day; no safety concern at authorised uses.

Why this class

Clean current EFSA and FDA status. These rows exist so that an unfamiliar additive is never treated as a bad one: a missing row costs a product nothing, and a clean row says so with citations.

Our confidence in this row's classification is high. Medium or low does not mean the evidence is weak; it means something about the row is still being pinned down, usually a regulatory status confirmed from one source rather than two.
