Xanthan gum is the thickener the food industry lists as E415. In our table it is no risk identified: it takes no points off a product's score.
- The key finding, from EFSA: Re-evaluation of xanthan gum (E 415): no need for a numerical ADI; no safety concern for the general population at the refined exposure assessment for reported uses (10.2903/j.efsa.2017.4909)
- No child flag. The class, and the points it costs, are the same for a child of any age.
- Where you meet it. It turns up in 321 of the 10,000 packaged foods scanned most on Open Food Facts, most often in sauces, ready meals and plant-based milks. Nine in ten of those foods are sold in Europe (counted 26 Sep 2026).
- 2 citations from EFSA and peer-reviewed research, each one below.
What Xanthan gum 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. Xanthan gum 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.

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

Peer-reviewed
PMID 22575248 (Beal J et al., J Pediatr 2012) and PMID 22289705 (Woods CW et al. 2012)
Case series of late-onset necrotising enterocolitis in (predominantly premature) infants following use of a xanthan-gum-containing thickening agent; the reports underpinned FDA's 2011 warning against SimplyThick in premature infants.
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.
Questions parents ask
Is Xanthan gum (E415) safe for kids?
No risk identified. No regulator finding we score, so a product keeps its full additive subscore in Sito. The current status is clean: Re-evaluation of xanthan gum (E 415): no need for a numerical ADI; no safety concern for the general population at the refined exposure assessment for reported uses (EFSA, 10.2903/j.efsa.2017.4909).
