FAQs

Gellan gum is an outstanding suspending agent primarily due to its unique "yield-stress weak gel" property.

1. Suspension Mechanism: A Scientific Perspective

When at rest, a gellan gum solution can form a weak gel with a three-dimensional network structure. This structure exhibits a definite yield stress—meaning that the system must overcome a critical stress threshold before it begins to flow. When the gravitational force acting on suspended particles is lower than this yield stress, the particles are stably "held" in place without settling or floating. This physical characteristic makes gellan gum particularly suitable for suspending fruit pulps, flavorings, colorants, solid particles, etc., and it can maintain stability over a wide temperature range.

3. Summary of Gellan Gum’s Suspension Advantages

• Low dosage, high efficiency: Only 0.02%–0.03% is needed to achieve stable suspension, offering significant cost-effectiveness.

• Clean mouthfeel and high clarity: Low system viscosity, non-sticky mouthfeel, providing products with a clear appearance and refreshing texture.

• Excellent stability: Heat-resistant and acid-tolerant, suitable for suspension systems requiring high-temperature processing or acidic environments.

• Good synergies: Can be combined with other gums to further optimize suspension performance and product texture.

Conclusion

Thanks to its unique "yield-stress weak gel" mechanism, gellan gum not only suspends efficiently but also offers comprehensive advantages such as high clarity, refreshing mouthfeel, and excellent stability. This makes it a valuable high-performance suspending agent in modern food and beverage applications.
