What Patent Blue V does to a score
A packaged food starts with 33 points for what is in its ingredient list. Patent Blue V takes 6 of the 33 additive 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.

EFSA
ANS Panel, Scientific Opinion on the re-evaluation of Patent Blue V (E 131) as a food additive, EFSA Journal 2013
ADI reduced from 15 to 5 mg/kg bw/day on the basis of adverse haematological effects after chronic intake of high doses.
Why this class
A credible adverse or precautionary signal that stops short of every Moderate and High criterion: peer-reviewed adverse findings not yet reflected in regulatory status, an exposure exceedance confined to high-percentile or single-event estimates, or a precautionary regulatory step short of those criteria — a reduced ADI, a data limitation noted without an adverse conclusion, a narrowed or conditioned authorisation, or a child-focused assessment or school-food law that covers the additive as part of a class.
Our confidence in this row's classification is medium. 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.
