Additive Table / Succinic acid

Succinic acid (E363)

Succinic acid is the acidity regulator the food industry lists as E363. 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 Agency review, EFSA, each one below.

What Succinic acid does to a score

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

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.

  • Agency review JECFA evaluation — succinic acid (ADI 'not specified')
    Natural constituent of plants and animals; tolerated at high dietary concentrations; does not represent a hazard at food-additive levels because of its normal metabolic role.
  • EFSA call for data (July 2024) — background document, re-evaluation of fumaric acid (E 297) and succinic acid (E 363)
    Re-evaluation opened in 2024; no safety conclusion published as of Aug 2026.

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.

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