Gellan gum (E418),Gellan Gum has many peculiar advantages:
1. Low dosage;
2. Excellent thermal and acid stability;
3. Good taste-releasing ability;
4. High transparency;
5. Adjustable gel elasticity and rigidity;
6. Good combinability.
Gellan gum is widely used in foods and various other fields.
(1)Typical foods prepared using gellan gum: Gelled desserts, jam, jelly, pudding, confectionery, sugarcoating of confectionery, frost of cake,
filling of cake or bread, and other foods, cakes, and pet foods.
(2) Other applications:
Microbiological media, capsules, perfumes, etc.
Structure of two types of gellan gum
The molecular structure of gellan gum is a straight chain based on repeating glucose, rhamnose and glucuronic acid units. In its native, or high acyl form,
two acyl substituents --- acetate and glycerate are present. Both substituents are located on the same glucose residue and, on average,
there is one glycerate per repeat and one acetate per every two repeats. The high acyl form produces soft, elastic, non-brittle gels,
whereas the low acyl form produces firm, non-elastic, brittle gels.
