What is κ-Carrageenan?
Chemical properties
sulfate content 20-36%, forms gels powder
The Uses of κ-Carrageenan
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.
The Uses of κ-Carrageenan
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.
What are the applications of Application
κ-Carrageenan is used in immobilization of microbial cells based on the growth of cell in gel
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.
