We guarantee good price of gellan gum with stable and trust-able quality with 10 years.
Gellan gum is a multi-functional gelling agent that can produce a wide variety of interesting textures.
It is extremely effective at low use levels and is available in two forms.
·High Acyl Gellan Gum forms soft,very elastic gels;·Low Acyl Gellan Gum forms firm,brittle gels.
Gellan gum (or E418) is a versatile gelling agent that can produce a wide variety of textures varying from firm, brittle gels that crumble in the mouth, to fluid or elastic gels (depending on conditions & type used). Itcan also be used as a thickening, stabilising and suspending agent. It sets exceptionally fast at ambient temperatures and enables outstanding flavour release.
What is Gellan Gum?
It is derived from Sphingomonas elodea, a bacteria that grows on an aquatic plant.
It forms gels when combined with foods rich in calcium, magnesium or potassium (high positive ion content). Calcium rich dairy products, calcium chloride etc may also be needed to aid setting.
Types of Gellan Gum gel achievable
1. Firm, brittle gel - Using low acyl gellan gum in very low concentrations - from just 0.1% -firm and brittle gels can be made. These gels are crystal clear, making them very appealing visually.
2. Fluid gel - By agitating low acyl gellan gum gels as they cool, fluid gels can be created. They have apparent low viscosity, yet have remarkable suspending properties, successfully suspending particles such as coloured spheres, herbs, and even gases.
3. Elastic gel - By incorporating high acyl gellan, a far more flexible result can be achieved. The resultant gel can be made into thin sheets that can be rolled or folded.
4. Spheres and strands - a pure, gellan gum solution can be dropped into an ion rich water solution to form gelled spheres or strands.
How should Gellan Gum be used?
As well as being heat stable, gellan gum is also stable over a wide pH range meaning it is suitable for use with many different foods. As with any molecular ingredient, experimentation is essential to achieve the desired effect.

·Setting Temperature;·Degree of structure;·Thermal stability;·Low viscosity suspension ability.
Gellan Gum has E number E418 and due to the above outstanding properties it is widely used in many products that require gelling,suspending,stabilizing,texturizing,
Popular field applications such as food, beverage, plant tissue culture,microbiological culture ,cosmetic, oral care,pharmaceutical and also in various industrial applications(air freshener industry Paper industry.etc).
Gellan Gum Origin:
-Gellan is an anionic polysaccharide, which is produced by Sphingomonas paucimobilis bacterium(ATCC31461) through aerobic fermentation. Purified by alcohol precipitation.-In 1978, in CP Kelco Kaneko and Kang found a water soluble polymer – gellan-In 1988, Japan approved gellan gum for use in food products.-In 1992,FDA approved the use of gellan gum as an food additive. It has E-number E418.
Structure:
High Acyl Gellan Gum forms soft,very elastic gels;Low Acyl Gellan Gum forms firm,brittle gels.
Features
-Forming gel ,low dosage(at lest 0.05%) forms gel-Excellent stability(PH ,Heat)-No protein interaction-Fluid gel(suspension)-High clarity-Flexibility in melting and setting temp.
Gel Formation
Dispersion
Poor dispersion will result in incomplete hydration and loss of gum functionality.
Solutions:
-Blending with dispersants such as sugar,sodium citrate etc.-Stirring or starting the agitator before adding.-Using well dispersion products such as KELCOGEL or CINOGEL GELLAN GUM
• Concentration of ions in solution will affect the hydration temp. such as calcium , Sodium
• Low acyl gellan gum requires a temperature of 75 ℃(1670F) to fully hydrate the gum.• High acyl gellan gum hydrates between 70℃ and 80 ℃(1580F and 1760F) even in relatively high ion concentrations
Gel formation
In the absence of added cations, low acyl gellan gum gels set at around 25℃ (770F), where high acyl sets at around 65℃ (1490F). With added calcium or sodium ions,the setting temperature increases.
