Gellan Gum F is a multi-functional gelling, suspending and thickening agent.
This product is mentioned in the following articles from the Virtual Kitchen.
Creating Hot & Flavoursome Gels
If you are looking to serve a gel on a hot plate, gelatine won’t do as it melts above 14-16 °C
So you need a heat-resistant gel.
Generally speaking, ..
Eat Sheffield Young Chef of the Year Awards 2013
We were really proud to sponsor, judge and present the award for the Eat Sheffield Young Chef of the Year Award on Monday night at Hallam University.
It ..Soluble in water, it is used primarily as an alternative to Agar Agar as a gelling agent . Its largest advantages over Agar Agar are its almost perfect visual clarity and its strength; it is able to withstand 120 degree Celsius heat.
Approximately half the amount of Gellan Gum F as Agar Agar is needed to reach an equivalent gel strength.
Gellan Gum F has many advantages:
Gellan Gum F can be used individually as well as jointly with other products.
Rate of Hydration: Requires heating to 100 ºC.
Gel Strength: Combining Gellan with other gelling agents yields a wider selection of gel strengths and textures.
Colour: White powder
Solubility: Hot
Ph Solubility: 3.5 - 8.0
Dosage Rates: 0.1% - 2.0%
Gellan Gum gels are beautifully clear and have a firm texture. Gellan Gum gels are heat resistant to 120° C, therefore not only will they withstand temperatures in the hottest kitchens but they can be heated and served hot! Gellan Gum gels have a non-adhesive texture and are therefore very easy to handle.
How Gellan Gum F is produced?
Gellan Gum F is a polysaccharide produced by sphingomonas elidea, a bacterium. Gellan Gum is prepared from a dried isolate of Pseudomonas elodea. This culture is fermented in a medium containing carbon, nitrogen and inorganic salts. The Gum resulting from this strictly controlled process will gel in the presence of ions in solution, the resulting gels are clear, and when used in food applications, are easily broken down in the mouth.
Applications: Heat resistant gels. Heat stable gels. Suspending Agent. Thickener.
Gels occur when hot Gellan Gum F solutions are allowed to cool and set under quiescent conditions. However, with low concentrations of Gellan Gum F, shearing the gel results in the formation of pourable fluid masses with very short, flowable texture. These systems, commonly known as fluid gels, can have a wide range of textures and can exist as a light pourable gel or a thick, spreadable paste. Gellan gels can withstand temperatures to 120oC.
Depending on the formulation, Gellan is able to form both heat-reversible and heat-stable gels. In addition, combining Gellan with other hydrocolloids, yields a wide selection of gel strengths and textures. Gels made from Gellan are typically resistant to enzymatic degradation and are stable in systems with pHs ranging from 3.5 to 8.0. Given the flexibility of Gellan, it is suitable for a great number of potential applications.
