Disodium inosinate (E631): What the Sources Found

Disodium inosinate is the flavour enhancer the food industry lists as E631. In our table it is no risk identified: it takes no points off a product's score for a child.

In short

No risk identified. No regulator finding we score, so a product keeps all 33 additive points.
No child flag. Nothing below is written about children specifically, so the class is the same at every age.
2 citations from FDA, EFSA, each one below.

What Disodium inosinate does to a score

A packaged food starts with 33 points for what is in its ingredient list. Disodium inosinate 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.

FDA 21 CFR 172.535 (govinfo CFR-2024-title21-vol3-sec172-535)
Disodium inosinate may be safely used as a flavouring adjuvant in food, subject to a soluble-barium limit of 150 ppm — an affirmative US food additive authorisation with no restriction relevant to children.
EFSA Call for data for the re-evaluation of ribonucleotides (E 626-635) as food additives, launched 2023-06-28 (efsa.europa.eu/en/call/call-data-re-evaluation-ribonucleotides-e-626-635-food-additives)
Re-evaluation of the ribonucleotide group under Reg. (EU) 257/2010 is under way and proceeded to opinion drafting with data gaps; no opinion published as of 2026-08, so there is no EFSA ADI, exposure assessment or child-specific finding to cite.

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 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.
