Food Science Glossary (Industrial Perspective)¶

Every term below is tied to the document that actually defines or governs it: EU food law and US federal regulation for statutory terms, ISO standards for methods and vocabulary, the UK Food Standards Agency's HACCP glossary for hazard terms, and peer-reviewed reviews where the concept is scientific rather than legal.

Where a term has no statutory definition — "formulation" is the clearest example — the entry says so rather than borrowing a definition from a non-authoritative source.
