Where this data comes from

The ingredient list analysed above is the community-maintained record for barcode 0884912004710 on OpenFoodFacts, last updated on 2026-05-23.

That record is crowd-sourced, which is worth knowing in both directions: it is often more detailed than a manufacturer's own website, and it can also lag a reformulation. The classification on this page is ours; the underlying ingredient text is theirs.
