Abstract: The present invention relates to a compound thickener comprising rhamsan gum and gellan gum. In the compound thickener, rhamsan gum accounts for 50%-95% of the total weight of rhamsan gum and gellan gum. The combination of rhamsan gum and gellan gum in the compound thickener produces a synergistic effect, and its viscosity is remarkably improved. The compound thickener can be applied to products such as foods, beverages, pharmaceutical products, and personal care products, and when the compound thickener is applied as a gelling agent in soft capsule shells, the shell strength and the shell elasticity are better.
