Applications · 3 items

Usesκ-​Carrageenan is a sulfated linear polysaccharide of D-​galactose and 3,​6-​anhydro-​D-​galactose extracted from certain red seaweeds of the Rhodophyceae class. κ-​Carrageenan is used in the food industry as thickening, gelling and protein-​suspending agents, and by the pharmaceutical industry in pills and tablets.

UsesThe carrageenans are sulphate gums found in members of the Rhodophyceae. They consist of mixtures of polysaccharides which are mainly composed of D-galactose units linked 1~3 and 1~4. A high proportion ofthe units are substituted with sulphate half-ester groups. The carrageenans are useful stabilisers in foods.
