The temperature effect on the viscosity and density ofxanthan gum solution

الملخص EN

Xanthan gum is a nontoxic polysaccharide with a good gelling, thickening and stabilizing attributes, and used widely in food and cosmetic industries.

Effect of temperature on the viscosity and density of various solutions of xanthan gum (0.1, 0.2, 0.3, 0.4 and 0.5 w / v %) were studied experimentally with temperatures range of 30 to 60 °C.

The experimental tests were performed using DV-11 + Pro viscometer at different speeds (50, 100 and 150rpm).

It has been noticed by measuring the viscosity changes, that efficiency of higher polymer concentrations, lower speeds and lower temperatures also.

The density increase by increasing concentration and decrease with temperatures.
