Is Calcium 5'-Ribonucleotides vegan?
Calcium 5'-Ribonucleotides
Calcium 5'-ribonucleotides is a food additive consisting of a calcium salt mixture of 5'-guanylate and 5'-inosinate, used as a flavour enhancer. It can be derived from yeast extract or animal sources, or produced via fermentation.
Why unconfirmed?
Calcium 5'-Ribonucleotides can be either derived from animal, or non-animal sources. The ingredient name itself is identical either way, so the label alone can’t tell you which. Only a supplier declaration can.
