Food Grade Gellan Gun Powder 99
Description
Gellan Gum is a kind of extra cellular polysaccharide excreted by microorganism Pseudomonas elodea. It is a linear structure with a repeating unit of tetrasaccharide. As a multi-functional gellingsuspending and thickening agent, it can be used individually as well as jointly with other products.
Gellan gum is a water-soluble anionic polysaccharide produced by the bacterium Sphingomonas elodea (the current taxonomic classification). It was originally identified as "Pseudomonas elodea" based on the taxonomic classification at the time of 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, USA. It 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 Its 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.
Comparison of Physical Properties of High Acyl and Low Acyl Gellan Gum
| High Acyl Gellan Gum | Low Acyl Gellan Gum |
Molecular Weight | 1~2×106 Daltons | 2~3×105 Daltons |
Solubility | Hot water above 70°C | Hot water above 80°C or cold water with sequestrants |
Sensitivity to cations | Relatively insensitive to ions | Very sensitive to ions, especially to divalent cations such as calcium ions |
Gelling conditions | Just Cooling ( do not need cations ) | Cations, acids or soluble solids |
Set temperature | 70~80°C (158~176°F) | 30~50°C (86~122°F) |
Thermoreversibility | Thermo-reversible | Heat stable if using divalent
|
Gel texture | Soft and elastic gels | Hard and brittle gels |
Differences
Low Acyl Gellan Gum is white powder.
1.The solution made by low acyl gellan gum is clear and with high transparency.
2.The gel strength of low acyl gellan gum is higher.
3.The gels formed by low acyl gellan gum are brittle and with high transparency.
4.Low Acyl Gellan Gum is perfect gelling agent and suspending agent.
High Acyl Gellan Gum is Dark Yellow Powder.
1.The solution made by high acyl gellan gum is not so clear and with lower transparency.
2.The gel strength of high acyl gellan gum is weak.
3.The gels formed by high acyl gellan gum are elastic and with low transparency.
4.The visocsity of high acyl gellan gum is higher than low acyl gellan gum so high acyl gellan gum can be as perfect thickening agent.
Remind Information of Application of Gellan Gum:
1.Materials without salts can be directly added into water together with gellan gum.
2.Materials with salts(or kations) should be added only when gellan gum is thoroughly dissolved.
3.The water used should be deionized water.
4.The application of gellan gum should be in addition with KATIONS( Ca, Mg, Cl, and so on).
5.Gellan Gum is soluble in cool water but need to heat up to 85℃-90℃ for thoroughly dissolving.
6.The dosage of gellan gum should be adjusted according to pH, materials added and particle sizes of fruit pulps. The higher dosage, the better performance.
Some Correspondent Questions About Gellan Gum:
1. Is Gellan Gum Vegetable Gum?
2. Where is Gellan Gum Derived from?
3. Is CAIXIN-SUGAR gellan gum HALAL certified?
Application
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.
Features of Low Acyl Gellan Gum Applications:
The Gels formed by our LOW ACYL GELLAN GUM is of high transparency and brittle texture as well as high gel strength:
The solution prepared by our LOW ACYL GELLAN GUM is clear and gellan gum can help the fruits pulps or crystalls suspending in the beverages:
Features of High Acyl Gellan Gum Applications:
High Acyl Gellan Gum is dark yellow powder.
The gels formed by high acyl gellan gum is elastic.
The solution prepared by high acyl gellan gum is a little cloudy, not so clear as the ones prepared by low acyl gellan gum.
But, High Acyl Gellan Gum can be used as thickener as well as stabilizer. High Acyl Gellan Gum is widely applied in yoghurt, ice cream, sausages, fruit and vegetable juice , soybean milk and dairy drinks.
