Usage

Uses

Different sources of media describe the Uses of 11114-20-8 differently. You can refer to the following data:
1. κ-?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.
2. The 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.

Chemical Properties

sulfate content 20-36%, forms gels powder

Definition

A naturally occurringpolysaccharide isolated from redalgae. The polymer is composed of dgalactoseunits, many of which aresulphated. K-carrageenan is a gellingagent with uses similar to those ofagar.
