Gellan Gum features and application uses

Gellan Gum

Gellan gum (E418) is a bacterial exopolysaccharide, prepared commercially by

aerobic submerged fermentation from Sphingomonas elodea (previously called Pseudomonas elodea), in a manner similar to xanthan. discovered in 1978,1988 Approved in Japan,1992 USA full approved.

Gellan gum are available in two content: High Acyl content & Low Acyl content.

Compared with other hydrocolloids, Gellan Gum has many peculiar features and 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 is widely used in foods and various other fields.

(1) Typical foods prepared using gellan gum: Gelled desserts, jam, jelly, pudding, confectionery, sugarcoating of confectionery, frost of cake, filling of cake or bread, and other foods, cakes, and pet foods.

(2) Other applications:

Microbiological media, capsules, perfumes, etc.

Characteristic and efficacy of Gellan Gum

Characteristic	Efficacy
1. Very Low dosage, form gel at 0.05-0.25% concentration	Gellan gum is a very effective gelling agent
2. Excellent thermal stability and acid stability	1. Little effect to gel strength after heat sterilization 2. Its powder form allows longer term of use and long-term stability even under acid condition.
3.Sodium or potassium irons can form thermal reversible gel, while Magnesium or calcium irons form thermal un-reversible gels	Can be made into thermal reversible and thermal un-reversible gels
4．Retains excellent flavor releasing ability	Improve product quality
5．Good combination with other hydrocolloids	Adjustable gel elasticity and rigidity
6．Good compatibility with other ingredients	Can be widely used in many formulations
7．Can form gel between pH 3.5~7.0	Can form high quality gels and have good gel strength in acid to neutral food formulations.
8.Anti-aging function	Prevent aging and viscosity raising of starch
9.Not easy lead to enzymolysis	Enabling flexibility in the manufacturing process, very suitable for Microbiological media and plant media.
