Xanthan gum and konjac gum were not concretionary polysaccharides.They showed the evident synergism of XG KG at different mixed ratio.The synergism was maximum when the mixed ratio was 7∶3,the viscosity of the mixed gum would descend after the temperature was raised and the rheology became good.With different content of citric acid,sweetener affected the viscosity of solution of xanthan/konjac gum mixtures.When the concentration of citric acid was higher than 0.2%,the viscosity fallen down.The swe...
