Gellan gum is a polysaccharide produced by fermentation of a pure culture of Sphingomonas elodea. After the fermentation process, it is dried and milled into powder for use in a variety of applications.
Gellan gum is a polymeric microbial metabolic gum. It is an extracellular polysaccharide produced by a Gram-negative bacterium derived from water lily, Pseudomonas aeruginosa (Sphingomonas paucimobilis), using small-molecule carbohydrate such as glucose as a substrate.
Gellan gum can be divided into two categories: high acyl gellan gum and low acyl gellan gum.Low acyl gellan gum products form firm, non-elastic, brittle gels, whereas high acyl gellan gum forms soft, very elastic, non-brittle gels.
Gellan gum is getting further and further attention from consumers, especially from food scientists, because of its excellent parcels similar as natural, safe, non-toxic and effective.
