Study on Factors Affecting Rheological Property of Welan Gum Aqueous Solution

Abstract

Abstract: The rheological property of welan gum solution was studied in this paper.In addition,the effects of temperature,pH and NaCl concentration on viscosity of welan gum solution were investigated.The results indicated that the welan gum solution exhibits a strong pseudoplastical properties characterized by shear-thinning behavior with an equation of lgb=lgK+(N-1)lga.Temperature from 25 to 100℃ and pH from 2 to 12 have little effects on the viscosity of welan gum solution,but the NaCl concentration shows clear influence.

Key words: welan gum, rheological property, viscosity
