Polysaccharides 674<br />

Therkelsen, G. H. (1993) Carrageenan. In: Whistler, R. L., and J. N. BeMiller (Eds.), Industrial<br />

Gums: Polysaccharides and Derivatives. 3rd edition, pp. 145–180.<br />

ANY OTHER RELEVANT INFORMATION: Carrageenans are natural sulphated polysaccharides which are extracted from red seaweeds<br />

(Rhodophyceae). Euchema spp., Chondrus crispus, Iridaea spp. and Gigartina spp. are the most<br />

important commercial sources of carrageenan. There is concern that low molecular-weight fractions of<br />

carrageenan could be toxic, and many manufacturers have voluntarily stopped using carrageenans in<br />

baby foods.<br />

Semi-refined carrageenans are not water extracts from seaweeds and as such did not match the legal<br />

definition of a carrageenan. They are extracted from seaweeds using an alternative process and differ<br />

from other carrageenans in that they contain significant amounts of celluloses.<br />
