Disodium guanylate is a chemical compound from the group of purine - nucleotides .
properties
Disodium guanylate is the sodium salt of guanosine monophosphate . The anion, like the anion of disodium inosinate, binds to the heterodimeric receptor consisting of T1R1 and T1R3 on the human tongue and enhances the effect of glutamate on the umami taste.
use
Disodium guanylate is used as a flavor enhancer with the E number E 627. It is mostly used in conjunction with glutamates due to its umami-enhancing effects, and often in conjunction with disodium inosinate. A 1: 1 mixture of disodium guanylate and disodium inosinate is known as disodium 5′-ribonucleotide (E 635). Disodium guanylate is found in all living things. In dried mushrooms and dried tomatoes occurs frequently before. For use in food, disodium guanylate is obtained from seaweed , yeast extract or marine animals . Since purine nucleotides are metabolized to uric acid , they should be avoided in gout .
