6.6 Carrageenan Carrageenan is a linear sulfated polysaccharide found in edible red seaweeds and it is water soluble. It is a linear polysaccharide with repeating structures of altering galactose and 3,6 anhydrogalactose units.
Else, how is carrageenan extracted from seaweed?
In the original method - the only one used until the late 1970s-early 1980s - the carrageenan is extracted from the seaweed into an aqueous solution, the seaweed residue is removed by filtration and then the carrageenan is recovered from the solution, eventually as a dry solid containing little else than carrageenan.
Nevertheless, how does carrageenan dissolve? Add 4 g of sample to 200 ml of water, and heat the mixture in a water bath at 80o, with constant stirring, until dissolved. Replace any water lost by evaporation, and allow the solution to cool to room temperature. It becomes viscous and may form a gel.
On top of this, is carrageenan safe for human consumption?
Is it safe for consumption? There need to be more human studies to confirm any link between carrageenan and digestive problems. In the meantime, you may want to limit how much carrageenan you consume. The Food and Drug Administration still approves this ingredient.
What's wrong with carrageenan?
But it certainly has. Some scientists have presented evidence that carrageenan is highly inflammatory and toxic to the digestive tract, and claim that it may be reponsible for colitis, IBS, rheumatoid arthritis, and even colon cancer.
