Carbonates is the acidity regulator the food industry lists as E502. 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.

What Carbonates does to a score
A packaged food starts with 33 points for what is in its ingredient list. Carbonates 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.

additives taxonomy node en:e502 (1,878 products world / 185 US)
Node exists in the OFF additives taxonomy without a corresponding entry in the EU Union list of food additives; behaves as a generic parent for the carbonate family.
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 low. 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.
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.
