Is Disodium Guanylate (E627) Halal?

Disodium guanylate can be produced by fermentation or extracted from yeast, but it has also been obtained from fish (sardines) and meat. Because the source cannot be determined from the E-number, MUIS lists it as doubtful. It is almost always used together with E631, or as the blend E635, so check those too. Halal-certified products use fermentation- or yeast-derived guanylate.

Disodium guanylate is a flavour enhancer derived from guanylic acid, a nucleotide naturally found in dried mushrooms, yeast extract and sardines. Commercial production uses either yeast or sardines/anchovies as starting material — supplier disclosure is essential for vegan/vegetarian labelling.

• Look for a recognised halal certification logo (MUIS, JAKIM, MUI, HMC or similar) on the packaging — certified products have had the source of this additive verified.
• Check whether the label states the origin, for example 'vegetable origin', 'plant-based' or 'soy'.
• If there is no certification and the origin is not stated, contact the manufacturer or choose a product with a halal alternative.
