Composition of Different Types of Gellan Gum


Composition of Different Types of Gellan Gum

The repeating unit of gellan polysaccharide is composed of b-D-glucose (D-Glc), L-rhamnose (L-Rha), andD-glucuronic acid (D-GlcA). 

The composition is approximately: glucose 60 %, rhamnose 20 % and glucuronic acid 20 %. 


In addition, considerable amount of non-polysaccharide material is found in gellan gum (cell protein and ash) that can be removed by filtration or centrifugation. 

An example of chemical composition of different type of gellan gum is illustrated in Table below:
