Food Additive Functional Classes

The food additive functional classes are based on the Codex Class Names and the International Numbering System (INS) for Food Additives (CAC/GL 36-1989).

Clicking a "functional class" will display a list of all food additives associated with that function.

Please Note that the functional classes listed below have not yet been aligned with the revised CAC/GL 36-1989 adopted by the 31st Session of the Codex Alimentarius Commission (July 2008).

Stabilizer
Makes it possible to maintain a uniform dispersion of two or more immiscible substances in a food.
  • colloidal stabilizer
