Scholarly view

Schools of law

Hanafi · Maliki · Shafi'i · HanbaliAll four accept these additives when they come from fermentation, plants, fish or properly slaughtered meat, and prohibit them from pork or from meat not slaughtered the Islamic way (zabiha). Because the label shows only the E-number, all four treat the bare code cautiously until the source is known.

What to do in the shop

Look for a product that names the source, says plant-based or vegan, or carries a Halal certificate. If nothing on the packet settles it, the manufacturer can tell you, and their answer is the only thing that turns E631 from a question into an answer.

A status here describes the additive in general, and a specific product can be different. The same number can be made from plant or animal material depending on the manufacturer, and the label does not say which.

Check a product, not just a number

An additive's status describes the additive in general. What matters is the whole ingredient list on the packet in your hand.

This is information, not a fatwa. These statuses combine published scholarly positions with ingredient analysis, and they can be incomplete or out of date. For anything that matters, confirm with the manufacturer and with a qualified authority.
