Toxicological properties of carrageenan.


PMID 2058470

Abstract

Food-grade carrageenan is a safe natural product prepared from seaweed. Its addition to food imparts many desirable characteristics which have allowed it to be used continuously for centuries. The long safe history of this natural food additive is confirmed by negative results in subchronic and chronic feeding studies in many animal species, mutagenicity studies and reproductive toxicity studies.
