Gellan gum

gellan gum is the extra-cellular polysaccharide produced by the gram-negative bacteria-pseudomonas elodea that is separated from water lily,and is one of the microbia polysaccharides full of the development prospect in teh recen years. As the emulsifier,suspension agent,thickener,stabilizer,gelling agent,tissue culture medium,film former and lubricant,gellan gum has been widely applied in over 20 fileds,such as food,cosmetics,detergent,ceramics,petroleum exploration and coating for chemical industry,it is considered as the most advanced food additive in the world. 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.
