Rheological modeling of cellulose gum, xanthan gum, and guar gum mixtures in aqueous solutions

Abstract

The synergistic effects observed in hydrocolloid mixtures hold significant potential for the discovery of new industrial products and compounds. Through an examination of the rheological behavior of mixtures of cellulose gum, xanthan gum, and guar gum, synergistic viscosity patterns were observed in binary mixtures. Notably, the viscosity of these mixtures exceeded that of the individual components. Binary and ternary systems with high elasticity and minimal temporal variation exhibited low levels of thixotropy and demonstrated stable elastic modulus values across various frequencies. Ternary mixtures containing a high proportion of xanthan gum exhibit enhanced stability in response to temperature fluctuations. This underscores the potential of hydrocolloid mixtures to yield novel functionalities by capitalizing on the distinct rheological behaviors arising from their interactions.
