ABSTRACT:
Two novel forms of xanthan gum containing not more than about 400 ppm of calcium are disclosed. Xanthan gum having this low concentration of calcium is prepared from an aqueous fermentation medium substantially free of calcium ion and substantially free of fermentation nutrients which contain calcium. When the fermentation is carried out under conditions of high shear, the low calcium product is characterized in that oil/water emulsions of the gum exhibit smooth flow.
