Depends on the sourceDepends on the source. E635 is a mix of E627 and E631. Most is made by fermentation or from yeast, which is halal, but it can be made from meat, which may be pork.
Depends on the source means it can be made from plants, microbes or minerals, or from animals, including pigs. From plants, microbes or a halal-slaughtered animal it is halal; from pigs it is not. The label often does not say which, so look for a halal logo, a vegan label or a note on the source, or ask the maker.
What it is and where it comes from
E635 is a mix of disodium guanylate (E627) and disodium inosinate (E631), often called I+G. It strengthens savoury taste, usually with MSG. Most is made by fermentation or from yeast extract, but both parts can also be taken from meat or fish.
Where you find it
Crisps, instant noodles, stock cubes, seasoning mixes and ready meals.
What to look for on the label
Look for a halal logo or a vegetarian or vegan label. Otherwise ask the maker for the source.
This is a guide, not a fatwa. Recipes change, so check the label, look for halal certification, and ask your local imam where scholars differ.
