E627: Disodium Guanylate
Main role: flavor enhancement
Also listed as: sodium guanylate, disodium 5'-guanylate
What is E627 (Disodium Guanylate)?
Disodium guanylate is the sodium salt of guanylic acid. It is often combined with other savory enhancers to build the flavor of soups, snacks, and seasoning preparations.
What does it do in food?
Its main role is flavor enhancement. Flavor enhancement changes how a recipe tastes. It does not replace the food’s protein, vegetables, or other nutrients. Salt and other seasonings may still be present, so compare the complete label.

Label names and ingredient questions
Look for E627, E 627, or the ingredient name. Related names and label terms include sodium guanylate, disodium 5'-guanylate. A family code can cover more than one specified form; check the full declaration when the distinction matters.
E627's source cannot be determined from the chemical name alone. If a dietary choice depends on animal, fish, or fermentation sourcing, ask the manufacturer.
Is E627 safe?
There is no meaningful personal risk estimate from an E number alone. Food-grade specifications, allowed uses, amount consumed, and individual circumstances all matter. The authorization record below gives the legal scope; it is not a claim that every possible use is appropriate.
A label identifies the ingredient but usually not its concentration. Calculating daily intake requires the amount in the food and the quantities eaten.
Authorization and conditions of use
The Great Britain food additive register lists E627 as Disodium guanylate. This is an entry subject to its stated conditions, not unrestricted permission for every food. The record links to the applicable authorization terms. For an EU product, use the European Commission food additive database to check the relevant food category and limits. Other countries may use different names or rules.
