Not everyone may be familiar with carrageenan, and this can be cause for confusion.
Food-grade carrageenan is the only type of carrageenan approved for use in foods. Yet, some critics have improperly cited scientific tests that examine poligeenan to make misleading claims about carrageenan. Poligeenan is a similar but wholly distinctive substance from carrageen that is never used in foods.
Some critics even go as far as to say carrageenan can be “degraded” in the body and turned into poligeenan; in fact, it is scientifically impossible for the human body to replicate the high temperatures and strong acids required to create poligeenan.
