Annatto is the color the food industry lists as E160b. In our table it is low risk: it takes 6 points off the additive subscore (about 2 of the 100).
- The key finding, from EFSA: ADIs derived: 6 mg bixin/kg bw/day and 0.3 mg norbixin/kg bw/day (10.2903/j.efsa.2016.4544)
- Flagged for young children. Set only where EFSA’s own exposure assessment shows toddlers or children exceeding or approaching the ADI, or where a regulator used explicitly child-specific language. For a child under 6 it moves up one class, to moderate risk.
- Where you meet it. It turns up in 72 of the 10,000 packaged foods scanned most on Open Food Facts, most often in chips, breakfast cereals and margarines. Nine in ten of those foods are sold in Europe (counted 26 Sep 2026).
- 2 citations from EFSA, each one below.
What Annatto does to a score
A packaged food's additive subscore starts at 100 and loses points for each additive on the label; that subscore is a third of the final score. Annatto takes 6 points off the additive subscore (about 2 of the 100), and a child under 6 sees it one class higher again. 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.

Scan a packaged food and Sito names the additives in it, then scores the product out of 100 for your child's age.

Norbixin dietary exposure exceeds the ADI at the high level (95th percentile) for toddlers and children; bixin below the ADI for all groups.
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 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.
Questions parents ask
Is Annatto (E160b) safe for kids?
Low risk. In Sito it takes 6 points off the additive subscore (about 2 of the 100). It is flagged for young children, so for a child under 6 it moves up one class, to moderate risk: 15 points off the additive subscore. The finding we rely on: ADIs derived: 6 mg bixin/kg bw/day and 0.3 mg norbixin/kg bw/day (EFSA, 10.2903/j.efsa.2016.4544).
What is E160b?
E160b is the E number for Annatto, a color. It is one of the forms of E160 (Carotenoids) in our table, with E160a, E160c and E160e. Open Food Facts tags it en:e160b.
