E627: Disodium guanylate

Flavour enhancer. Origin: Plant or animal (varies by manufacturer).

Vegan

Depends on the source

Halal

Mushbooh (doubtful)

The honest version

Can come from yeast or from fish. Same practical advice as E631: without a vegan label, the source is unknowable.

When our checker meets E627 on a label, it does not guess: products carrying ambiguous additives get a “check the label” verdict, with the ingredient named, so you can decide or ask the manufacturer.
