Is Carrageenan (E407 / INS 407) Halal?
carrageenan is doubtful (mushbooh) — its halal status depends on the source. Reclassified from halal to doubtful: a seaweed gum, but not Halal if ethyl alcohol is used in processing.
Why this status?
Reclassified from halal to doubtful: a seaweed gum, but not Halal if ethyl alcohol is used in processing. Halal if isopropyl alcohol (fully removed), potassium chloride, or no such solvent is used.
Editorial summary
This summary is editorial and is general information, not a religious ruling. The status above is unchanged.
What it is
Carrageenan, E407, is a gelling and thickening agent extracted from red seaweeds. It is used in dairy desserts, chocolate milk, ice cream, plant-based milks, processed meats, jellies and some toothpastes. A less refined form made from Eucheuma seaweed is sold as processed Eucheuma seaweed, E407a. The seaweed itself is a plant from the sea and raises no halal question.
Why the status is doubtful
This entry was reclassified from halal to doubtful because of how carrageenan can be processed. Our rating says it is not halal if ethyl alcohol is used in processing, and halal if isopropyl alcohol is used and fully removed, or if it is recovered without alcohol, for example with potassium chloride. Manufacturers do not state the method on the label of the finished food, which is why this entry is rated doubtful (mushbooh).
What the safety review says
The European Food Safety Authority re-evaluated carrageenan and processed Eucheuma seaweed together in 2018. It kept the group acceptable daily intake of 75 milligrams per kilogram of body weight per day but made it temporary while more data were collected, and it found no genotoxicity or carcinogenicity concern. The panel also flagged uncertainties, including how relevant carrageenan is for people with existing inflammatory bowel disease. These are safety findings and do not address halal status.
Reading a label
On a label it may appear as carrageenan, E407, Irish moss, or processed Eucheuma seaweed, E407a. It is often used alongside other gums such as locust bean gum or guar gum, and in dairy desserts and chocolate drinks the gelatin, colours and flavourings in the same product can raise their own questions. A product with a recognized halal certificate settles both the processing question and the rest of the ingredient list, and a manufacturer can usually say which recovery method its carrageenan supplier uses.
Alternatives
If you want to avoid the question in home cooking, agar, pectin and starches can do similar gelling and thickening jobs, although each behaves a little differently and pectin carries a processing question of its own on this site.
In short
In short, carrageenan comes from seaweed and is not a problem in itself, but ethyl alcohol in its processing would be, the label does not say, and a halal certificate or the manufacturer's answer is what decides it.
Also listed on labels as
carrageenan can appear on an ingredient list as E407, Irish moss extract.
What to ask the manufacturer
Ask the manufacturer in writing where the ingredient comes from: whether it is plant, microbial or animal in origin, and if it is animal, which animal and how it was slaughtered. Ask whether any alcohol was used as a solvent or carrier, and whether the product carries a halal certificate from a body your local authority recognizes. Keep the answer, because suppliers and recipes change.
