Glossary
ADI ADI refers to the “Acceptable Daily Intake” and describes the amount of a substance that any individual can safely consume over a life time without it posing an appreciable/inacceptable health risk. The concept is used for substances such as additives, pesticide residues or veterinary drugs. In the US, the FDA also uses the concept for food contact materials. Benzophenone Benzophenone (CAS 119-61-9) is an organic compound which is used as a photoinitiator in printing inks applied to food […]
