PROBLEM TO BE SOLVED: To obtain xanthan gum having high viscosity characteristic, excellent resistance to salt when made into an aqueous solution and uniform dispersibility into water and useful as a thickener in a food filed, a cosmetic field and an agrochemical field, etc., a stabilizer or an additive. SOLUTION: The objective xanthan gum is obtained by heating xanthan gum containing >=0.01 wt.% of non-volatile organic solvent preferably having >=120 deg.C boiling point and <=90 deg.C melting point and preferably as a solvent (e.g. 1,3-butylene glycol) having more than one kind of substituting group selected from an ester group, hydroxy group and carboxy group at >=80 deg.C, preferably 120-150 deg.C for 15 min-4 hrs. Preferably, the heating treatment is performed after spraying the non-volatile organic solvent to the xanthan gum in the air.
