Abstract

The paper presents the results of experimental studies of structural and mechanical (rheological) properties of model samples containing xanthan gum and guar gum in different amounts (0.1 to 2%) and ratios. It is proved that the optimum for further studies, in terms of consumer characteristics are base containing a mixture of xanthan (0.8%) and guar (0.2%) gums. Based on the fact that rheogram model samples outside the boundaries of the rheological optimum for improving the rheological properties (effective viscosity, plasticity) models introduced hydrophilic non-aqueous solvents. It is shown that there is an optimal combination of glycerol (10%) and ethanol (5%) in the sample model. Reoparametry model sample is in the boundaries of the rheological optimum.
