The present inventions relates to a method for the production of gellan gum, under mixing conditions, the method comprising a) providing a fermentation broth or other liquid medium containing gellan gum, b) if necessary adjusting the temperature and the pH of the fermentation broth/liquid medium to allow or facilitate enzymatic treatment in step c, c) adding one or more enzymes capable of reducing or abolishing the enzymatic activity of S. elodea derived arylsulfatase and/orβ-glucuronidase, said one or more enzymes being added in an amount sufficient to reduce or abolish the enzymatic activity of S. elodea derived arylsulfatase and/orβ-glucuronidase in the broth/liquid medium, and/or treating the broth/liquid medium at a temperature between 90° C. and 125° C. for a period of time sufficient to reduce or abolish the enzymatic activity of S. elodea derived arylsulfatase and/orβ-glucuronidase in the broth/liquid medium, and d) optionally recovering the gellan gum from the gellan gum containing broth/liquid medium.
