Abstract: The gelling properties of welan-xanthan systems, and the effects of temperature, time, freezing-thawing alternation, pH, NaCl and citric acid on it were investigated in this research. The results showed that the welan-xanthan system had good gelling ability. Temperature and time had effect on welan-xanthan systems. When the mass ratio of welan gum to xanthan gum was 20 ml/80 ml, the synergistic interaction was the strongest. The further research indicated that freezing-thawing alternation, pH, NaCl and citric acid had little effect on the compound gum.

Key words: xanthan gum, welan gum, synergistic effect, viscosity
