Is Sanko Rice Cracker (Shrimp) Halal?

E635 - MUSHBOOH E627 - MUSHBOOH E631 - MUSHBOOH Contains shrimp (seafood) which is generally permissible, but it also lists flavor enhancers (ribonucleotide disodium/inosinate/guanylate) that can be animal-derived (possibly pork). Because the source of these additives is unclear, the halal status is doubtful — verify ingredient origin or look for halal certification.
