What are E numbers?
An E number on a label often raises questions. It's really nothing more than a code.
A European code
The E stands for Europe. An E number is a code for an additive that's approved in the EU. Every substance is assessed first by the European food safety authority EFSA.
What the numbers tell you
The numbers are grouped:
- E100 to E199: colours
- E200 to E299: preservatives
- E300 to E399: antioxidants and acidity regulators
- E400 to E499: thickeners, emulsifiers and stabilisers
Familiar examples
E300 is simply ascorbic acid, better known as vitamin C. E330 is citric acid. And E460 is cellulose, a plant fibre often found in tablets.
