Abstract:

Rheological properties of xanthan and welan gums were studied, and their viscosity affected by concentration, temperature, shearing rate, pH, freezing-thawing and cold store was compared in this study. A novel kind of microbial exopolysaccharides, welan gum shows wide application future due to its high temperature stability, pH tolerance and good environment-friendly properties.

Key words: xanthan gum, welan gum, rheology, high temperature
