My watch list  

E number

E numbers are codes for food additives and are usually found on food labels throughout the European Union. The numbering scheme follows that of the International Numbering System (INS) as determined by the Codex Alimentarius committee. Only a subset of the INS additives are approved for use in the European Union, giving rise to the 'E' prefix.

E numbers are also encountered on food labeling in other jurisdictions, including the GCC, Australia, New Zealand and Israel. They are increasingly (though still rarely) found on North American packaging, especially in Canada.
