Dairy-Free E-Numbers — The Quick Reference List

A quick-reference version of our dairy guide: the small set of E-numbers that can involve milk, and confirmation that everything else is dairy-free.

Always milk-derived: lactitol (E966). Can involve dairy in production: lactic acid (E270), lactates (E325–E327), nisin (E234) and historically riboflavin (E101). Everything else in the additive system — every colour, every emulsifier, every sweetener apart from lactitol — is dairy-free. Milk is a declared allergen, so deliberate dairy content must always be labelled in bold.
