A gellan gum product having double setting temperatures, its preparation method and use thereof are provided. The obtained product has low setting temperatures, and the provided preparation method has the advantages of simple pretreatment of fermentation broth, shortened production cycle and direct extraction of such gellan gum product from the fermentation broth

Gellan gum with double setting temperatures and the preparation method and use thereof

A method for preparing high transparent low acyl gellan gum from fermentation broth is provided, in which two-stage filtrations are carried out on deacylated gellan gum fermentation broth by using diatomite and/or perlite with different particle sizes as filter aid and filter media. The obtained product has high gel transparency and low content of metal ions. The method also has the advantages of simple pretreatment of fermentation broth, high impurities removal efficiency, simple operation, and easy to be industrialized.
