Inosinic acid is the flavor enhancer the food industry lists as E630. In our table it is no risk identified: it takes no points off a product's score.
- The key finding, from the FDA: The inosinate family holds an affirmative US food additive authorisation as a flavouring adjuvant, with no restriction relevant to children (21 CFR 172.535 (disodium inosinate, govinfo CFR-2024-title21-vol3))
- No child flag. The class, and the points it costs, are the same for a child of any age.
- Where you meet it. None of the 10,000 packaged foods scanned most on Open Food Facts list it. Nine in ten of those foods are sold in Europe (counted 26 Sep 2026).
- 2 citations from the FDA and EFSA, each one below.
What Inosinic acid 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. Inosinic acid 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.
See what is in your own cupboard
Scan a packaged food and Sito names the additives in it, then scores the product out of 100 for your child's age.
What the sources found
Every classification in our table comes from the citations below, and nothing else. Each finding is our one-line summary of what the source concluded, with the source and reference beside it.

FDA
21 CFR 172.535 (disodium inosinate, govinfo CFR-2024-title21-vol3)
The inosinate family holds an affirmative US food additive authorisation as a flavouring adjuvant, with no restriction relevant to children. -
EFSA
Call for data for the re-evaluation of ribonucleotides (E 626-635), 2023-06-28
E 630 is inside the ribonucleotide group re-evaluation, which has produced no opinion, ADI or age-group exposure assessment as of 2026-08.
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.
Questions parents ask
Is Inosinic acid (E630) 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: The inosinate family holds an affirmative US food additive authorisation as a flavouring adjuvant, with no restriction relevant to children (FDA, 21 CFR 172.535 (disodium inosinate, govinfo CFR-2024-title21-vol3)).
