This paper has made further studies on the synergistic interaction and stability of salt tolerance between xanthan gum and other common food gums. It turns out that there is no synergistic interaction between xanthan gum and hydroxypropyl starch , CMC-Na. Xanthan gum and guar gum ,locust bean gum ,konjak flour have great synergistic interaction. If two or three of them mix with proper proportion, the stability of salt tolerance will greatly improve and the consumption is less than any other simple gum, further more, the cost will decrease a lot. So the complex thickeners have a obvious superiority and wide utilization in high salty food.
