Carbon dioxide is the additive the food industry lists as E290. In our table it is no risk identified: it takes no points off a product's score for a child.
- 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.
- 1 citation from FDA, each one below.
What Carbon dioxide does to a score
A packaged food starts with 33 points for what is in its ingredient list. Carbon dioxide 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.

Substances Added to Food inventory — carbon dioxide
GRAS direct food substance (propellant, carbonating agent, packaging gas).
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.
