E-numbers: every food additive, rated

E-numbers are the codes for additives approved for use in the EU: colours, preservatives, sweeteners, emulsifiers and more. Below are 191 of them, each with a plain-English safety rating grounded in EFSA scientific opinions, and the reason behind it. 62 are worth avoiding, 64 worth watching, and 65 carry no significant concern.

Avoid · 62
