Abstract:
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.

Claim (Index 1):
A method for preparing purified low acyl gellan gum from gellan gum fermentation broth, wherein the method comprises the following steps:\n 1) Deacylation of gellan gum fermentation broth, to obtain deacylated gellan gum solution; 2) First filtration of the deacylated gellan gum solution obtained in step 1), wherein used filter aid and filter media are diatomite and/or perlite with large particle size; 3) Second filtration of the gellan gum solution obtained in step 2), wherein used filter aid and/or filter media comprise diatomite and/or perlite with small particle size; and 4) Alcohol precipitation of the gellan gum solution obtained in step 3), drying, and milling to obtain the gellan gum product.
