The present invention is related a high viscosity xanthan and processes for producing said high viscosity xanthan. In particular, the invention relates to a process for increasing the viscosity of xanthan comprising the steps of: (i) diluting xanthan in a fermentation broth with more than 30 percent by volume of a diluent to said fermentation broth volume; and (ii) pasteurizing said diluted xanthan fermentation broth. A particularly preferred pasteurization process is to utilize steam from a direct steam injection system. Xanthans with increased viscosities have improved product functionality for a number of different commercial applications are produced using the processes of the present invention.
