Gellan Gum
- ClassificationHigh Acyl Gellan Gum:
High acyl gellan gum can form soft, very elastic, non-brittle gels
Low Acyl Gellan Gum: Low acyl gellan gum can form hard, non-elastic, brittle gels Varying the ratios of the two forms of gellan gum produces a wide variety of texture.

- PropertiesNeed to heat up first
The existence of a certain amount of cations. In this way, the gellan gum solution can form gel after It is cooled down. The gel strength, gel forming temperature and the melting temperature is bound up with the concentration and category of the cations....
- Characteristic And EfficacyCharacteristic:
Form high qualified gel under low concentration of 0.05~0.25%
High stability at high temperature and low pH value
Gel formed by Na+ and K+ can renew after heating, while gel formed by Mg2+ and Ca2+ can not ...
Gellan Gum (E418) is a kind of extra cellular polysaccharide excreted by microorganism Pseudomonas elodea. It is a linear structure with a repeating unit of tetrasaccharide. As the emulsifier, suspending agent, thickener, stabilizer, gelling agent, tissue culture medium, film former and lubricant, gellan gum has been widely applied in over 20 fields, such as food, cosmetics, detergent, ceramics, petroleum exploration and coating for chemical industry.
Compared with other colloids, Gellan Gum has many peculiar advantages:
1、 Low dosage;
2、 Excellent thermal and acid stability;
3、 Good taste-releasing ability;
4、 High transparency;
5、 Adjustable gel elasticity and rigidity;
6、 Good combinability.
Gellan Gum:Type
The Gellan gum has two types, the high acyl and low acyl type, the specific difference is as follows:
High Acyl Gellan Gum
High acyl gellan gum can form soft, very elastic, non-brittle gels
