Synergistic effects between polysaccharides such as locust bean gum, xanthan gum, guar gum, carrageenan, related to their thickening properties are widely known and used in food industry.

These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
