E631Caution

Disodium inosinate

Group: Flavour enhancers · in the book

Harm level3 of 5In moderation

In plain words

Disodium inosinate is an umami flavour enhancer usually added together with MSG. You meet it in instant soups, crisps, sauces and ready meals.

Where you find it: instant soups, crisps, stock cubes, seasoning mixes

Our recommendation

We recommend limiting it; people with gout or high uric acid should avoid it.

Possible risks and effects

  • Contains purines that turn into uric acid – unsuitable with gout and high uric acid.
  • Usually combined with MSG, boosting the overall umami effect.
  • May be of animal origin (e.g. fish), relevant for vegans.

For experts

The sodium salt of inosine monophosphate (a nucleotide), produced by fermentation or from animal sources such as meat or fish. It acts strongly in synergy with glutamate, so very small amounts suffice; it is not considered toxic at normal use, the main limitation being its purine content.
