Not kosher
Description: Guanytrc acid (flavour enhancer)
Function: flavour enhancer
Rationale:
Guanylic acid and the guanylate/inosinate/ribonucleotide family (E626-E635) can be produced from dried fish, meat (including pork), or yeast, and multiple additive-sourcing references flag them as doubtful/mushbooh without reliable certification of vegetal/kosher-fish origin.
If you don't see a status above, it does not mean the additive is not kosher automatically - it might just not be documented in our database yet.
