What is E630?
E630 is Inosinic acid, a food additive used as a flavour enhancer. Can be made from meat (including pork) or fish. Halal if the product is vegetarian-labelled or certified.

How E630 is made and where it is used
This section is food science. The religious classification is explained further down.
Inosinic acid is a flavour enhancer that boosts savoury taste.
Traditionally extracted from meat and fish (including dried bonito). Today it is mostly produced by fermentation of sugars, but animal-derived products are still sold.
It is uncommon on labels; its sodium salt E631 is far more common.
What to do
Look for a halal logo, a "vegan" label, or a stated plant source on the pack. If none of these are present, you can contact the manufacturer and ask for the source.
Is E630 vegetarian or vegan?
Not always. E630 (Inosinic acid) can be made from plant or animal sources, and labels rarely say which. A vegetarian or vegan label on the pack confirms a plant or synthetic source.
Why we classify it this way
Doubtful Can be made from meat (including pork) or fish. Halal if the product is vegetarian-labelled or certified.
Basis: Source or process not stated. It can be made from sources that change the ruling (for example pigs, an animal that was not slaughtered correctly, or alcohol), and the label does not say which.

Defines istihalah as a complete change into a different substance and says a partial change does not make a defiled substance pure. Adopts a 1995 IOMS fatwa that allows a slight amount of alcohol as a solvent for colours and preservatives, and alcohol on the skin, but says foods containing wine are not permitted even in a small ratio. Pig fat and pig rennet are prohibited; rennet from a correctly slaughtered animal is permitted; most participants hold rennet from an animal that was not slaughtered impure while some disagree; rennet made by genetic engineering is permitted. Pig heparin only under necessity. Gelatin was referred for further study with no ruling.
