Gellan gum is a water-soluble anionic polysaccharide produced by the bacterium Sphingomonas elodea (formerly Pseudomonas elodea based on the taxonomic classification at the time of its discovery).The gellan-producing bacterium was discovered and isolated by the former Kelco Division of Merck & Company, Inc. in 1978 from the lily plant tissue from a natural pond in Pennsylvania.
Gellan gum was initially identified as a substitute gelling agent at significantly lower use level to replace agar in solid culture media for the growth of various microorganisms.
Gellan gums initial commercial product with the trademark as Gelrite gellan gum, was subsequently identified as a suitable agar substitute as gelling agent in various clinical bacteriological media.
The repeating unit of the polymer is a tetrasaccharide, which consists of two residues of D-glucose and one of each residues of L-rhamnose and D-glucuronic acid. The tetrasaccharide repeat has the following structure:
Gellan gum products are generally put into two categories, low acyl and high acyl depending on number of acetate groups attached to the polymer. The low acyl gellan gum products form firm, non-elastic, brittle gels, whereas the high acyl gellan gum forms soft and elastic gels.
Microbiological gelling agent
Gellan gum is initially used as a gelling agent, alternative to agar, in microbiological culture.
Gellan gum is able to withstand 120 °C heat.
Gellan gum was identified as an especially useful gelling agent in culturing thermophilic microorganisms.One needs only approximately half the amount of gellan gum as agar to reach an equivalent gel strength, though the exact texture and quality depends on the concentration of the divalent cations present.
Gellan gum is also used as gelling agent in plant cell culture on Petri dishes, as it provides a very clear gel, facilitating light microscopical analyses of the cells and tissues. Although advertised as being inert, experiments with the moss Physcomitrella patens have shown that choice of the gelling agent—agar or Gelrite—does influence phytohormone sensitivity of the plant cell culture.
As a food additive, gellan gum was first approved for food use in Japan (1988). Gellan gum has subsequently been approved for food, non-food, cosmetic and pharmaceutical uses by many other countries such as US, Canada, China, Korea and the European Union etc.
Gellan gum is widely used as a thickener, emulsifier, and stabilizer.
Gellan gum has E number E418.
Gellan gum was an integral part of the now defunct Orbitz soft drink.
Gellan gum is used as the gelling agent, as an alternative to gelatin, in the manufacture of vegan varieties of "gum" candies.
Gellan gum is used in plant-based milks to keep plant protein suspended in the milk.
Gellan gum has also become popular in haute cuisine, and in particular in molecular gastronomy and other scientifically-informed schools of cooking, to make flavorful gels; British chef Heston Blumenthal and American chef Wylie Dufresne are generally considered to be the earliest chefs to incorporate gellan into high-end restaurant cooking, but other chefs have since adopted the innovation.
Gellan gum, when properly hydrated, can be used in ice cream and sorbet recipes that behave as a fluid gel after churning. The benefit of using gellan gum is that the ice cream or sorbet can be set in a dish of flaming alcohol without actually melting.

The high molecular weight polysaccharide is principally composed of a tetrasaccharide repeating unit of one rhamnose, one glucuronic acid, and two glucose units, and is substituted with acyl (glyceryl and acetyl) groups as the O-glycosidically-linked esters. The glucuronic acid is neutralized to a mixed potassium, sodium, calcium, and magnesium salt.

What is Gellan Gum?
Gellan gum is a food additive used to bind and stabilize processed foods.
Gellan gum is similar to other gelling agents, including guar gum, carrageenan, agar agar, and xanthan gum.
Gellan gum grows naturally, but can also be produced artificially by fermenting the sugar with a specific strain of bacteria.
Gellan gum is used in place of other popular gelling agents because it is effective in very small amounts and produces a clear gel that is not heat sensitive.
Gellan gum is also a plant-based alternative to gelatin derived from animal skin, cartilage or bone.
Can be used for texturing and stabilization in food preparation
The most common use of Gellan gum is either alone or mixed with other products/stabilizers to prevent separation of ingredients when cooking, preparing desserts or baking.
Gellan gum is very useful for adding to purees or a gel consistency, especially since it does not change the color or taste of foods. In addition, it does not turn into liquid even when heated, it preserves its structure.
Thanks to its ability to increase viscosity, gellan gum can produce a wide variety of interesting liquid textures, including thicker liquids, marinades, sauces or vegetable purees.

Main attributes of gellan gum in baking include:
Gelling agent: produces an elastic and thermoreversible gel similar to gelatin.
Thickener: mainly in jellies
Binding agent: essential for vegan and gluten-free products.
Flavor release agent: provides excellent flavor release in fruit jellies.
Improves water holding capacity during processing and storage
Reduces oil uptake and aids in formation of films or coat barriers.
Vegan and gluten-free baked goods can benefit from gellan gum’s binding capacity and organic origin, thus making it a suitable partial substitute for eggs and wheat flour.In jellies and fillings it improves texture while providing excellent flavor release in comparison with other gums.
Steps for incorporating this into formulations:
High-acyl gellan gum is heated up to 85 – 95 oC (185 – 203 oF) in a solution with less than 40% soluble solids, with water or milk as media and calcium citrate. Agitation is needed for gel formation.
Low-acyl gellan gum is heated up to 75 oC (167oF) in water or milk as media, with calcium citrate. Agitation is needed for gel formation. Salt concentration should not exceed 1.3%.
Gellan gum (also known as Phytagel, Gelzan, Gelrite, or Applied gel) is a water soluble anionic polysaccharide produced by fermentation of a carbohydrate by pseudomonas Elodea, purified, dried, and powdered.
Gellan gum is ideal for preparation of nutrient media for in plant tissue culture work and is a substitute for agar. Gels produced with gellan gum are clearer in comparison to agar. However, the gel is more rigid and brittle than agar gel.
Gellan gum requires roughly half the amount of agar that is needed.
Gellan gum melts at 80°C– 100°C and gels between 10°C-50°C.
Gellan gum is a natural ingredient that has found a versatile role within the food and beverage industries.

Gellan gum is available in high-acyl and low-acyl grades, which are distinguished by further processing. Both types of gellan gum are exudates derived from the fermentation process of certain microorganisms.
High-acyl gellan gum – This type, also referred to as native gellan, is recovered after fermentation through a process called alcohol precipitation. High-acyl gellan gum yields a soft, elastic gel after heating and cooling. This gel is particularly versatile due to its thermal reversibility and suspension properties.
Low-acyl gellan gum – Like high-acyl, this grade also solubilizes when heated. But once cooled, it forms firm, thermally stable gels. Low-acyl gellan gum requires calcium to produce maximum gel strength.

Gellan Gum is a gum obtained by fermentation of the microorganism sphingomonas elodea. the constituent sugars are glucose, glucuronic acid, and rhamnose in the molecular ratio of 2:1:1, being linked together to give a primary structure consisting of a linear tetrasac- charine repeating unit. direct recovery yields the gum in its native or high acyl form in which two acyl substituents, acetate and glycerate, are present. gels from that form are elastic and cohesive. recovery after deacetylation has the acyl groups removed to yield the low acyl form; those gels are strong and brittle. in general, high acyl gellan gum dispersed in water swells to form a thick suspension and upon heating, it loses its viscosity upon hydration. low acyl gellan gum is only partially soluble in cold water and is dissolved by heating to 70°c or greater. gelation occurs upon cooling and reaction with ions, predominantly calcium ions. gellan gum is sensitive to ions. uses include bakery fruit fillings, confectioneries, icings, dairy prod- ucts, beverages, and coatings.
