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.
