E407aCaution

Processed eucheuma seaweed

Group: Thickeners

Harm level3 of 5In moderation

In plain words

Processed eucheuma seaweed is a less refined form of carrageenan that still contains some of the seaweed's fibre. It is added as a thickener to desserts, dairy products, meat products and jellies.

Where you find it: dairy desserts, meat products

Our recommendation

Limit it as you would E407; with inflammatory bowel disease, better avoid it.

Possible risks and effects

  • Same possible gut effects as E407 (evidence mainly from animals)
  • Caution with IBD and sensitive digestion

For experts

Produced by alkaline treatment of Eucheuma seaweed without extraction, so it contains carrageenan together with cellulose (up to about 15%). It serves the same technological role as E407, and EFSA assessed both together in 2017 under a temporary group ADI. The same gut-related reservations apply and rest mainly on animal and in-vitro studies.
