High Acyl Gellan Gum

Properties

1. Good dispersion and hydration characteristics: Gellan gum can be evenly dispersed in cold water. After heating, it will hydrate with water molecules to form an aqueous solution. 

2.Excellent thickening and stability performance.The formed gel is softer and has excellent elasticity than the gel which is formed by low acyl gellan gum; it is resistant to acid and alkali and to enzymatic hydrolysis. 

3.The gel is reversible: It has thermal reversibility and shear reversibiity. When the temperature of the gellan gum solution drops to the gel temperature, a gel is formed immediately, and when the temperature is higher than the gel temperature, a disorderly curl is formed in the water. 

4.It has good pseudoplastic rheology: It has the characteristics of shear thinning which endows the product with good taste. 

5.It has low protein reaction and acid stability;

6. Melting point adjust-ability: The type and concentration affect the melting point of gellan gum. Divalent cations have a stronger influence on gel formation than monovalent cations. 

7.Histocompatibility and recombination: It has good compatibility with other hydrophilic colloids. 

8.It has good freeze-thaw resistance and film-forming properties.
