Look up a food additive

One page per additive, answering what it is, what it is derived from, every name it appears under on a label, and — the part nobody has published as structured data —where it is and is not legal.

Every fact carries its source and the date we retrieved it. Where regulators read the same evidence differently, both readings appear, attributed. This site does not rate additives, does not tell you what to eat, and has no opinion on whether any substance is safe.
