Gellan Gum
Detailed 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 emulsifier,suspension agent,thickener,stabilizer, gelling agent, tissue culture medium,film former and lubricant,gellan gum has been widely used in over 20 fileds, such as food, cosmetics, detergent, ceramics, petroleum exploration and coating for chemical industry, it is considered as one of the most advanced food additive in the world.
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.
5.The application of gellan gum should be in addition with KATIONS( Ca, Mg, Cl, and so on).
6.Gellan Gum is soluble in cool water but need to heat up to 85C-90C for throughly dissolved.
High Acyl Gellan Gum is Dark Yellow Powder.
The solution made by high acyl gellan gum is not so clear and with lower transparency.
The gel strength of high acyl gellan gum is weak.
The gels formed by high acyl gellan gum are elastic and with low transparency.
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.
The application of gellan gum should be in addition with KATIONS( Ca, Mg, Cl, and so on).
Gellan Gum is soluble in cool water but need to heat up to 85C-90C for throughly dissolved.
Compared with other colloids, Gellan Gum has many peculiar advantages:
1.Low dosage;
2.Excellent thermal and acid stability;
3.Better taste-releasing ability;
4.High transparency;
5.Adjustable gel elasticity and rigidity;
6.Good compatibility with other ingredients.
