What is an E-number?
An E-number is a standardised code for an approved food additive, used across the EU and Norway. The E stands for 'Europe'. The numbers are grouped by function: colours (E100s), preservatives (E200s), antioxidants (E300s), thickeners (E400s) and so on.
Having an E-number doesn't mean something is dangerous, many are entirely natural (E300 is simply vitamin C). But some people want to limit certain additives, and then it's useful to quickly see what's in a product.
