FAQs

Why is my gellan gum gel too brittle?

Excessive brittleness is a typical characteristic of low‑acyl gellan gum, especially at higher gel concentrations or in the presence of calcium ions. Research on gellan gum blends shows that simply adding non‑gelling thickeners—such as xanthan gum, guar gum, or CMC—mainly acts as an inert diluent. While these additives can slightly reduce hardness and increase elasticity, they cannot fundamentally change the brittle nature of low‑acyl gels.

If you need a softer, more elastic texture (for example, in vegan gummies or cultured products), we recommend switching to a high‑acyl gellan gum or using a low‑acyl / high‑acyl blend.

Quick comparison:

CAG also supply transparent high acyl gellan gum 

If you are currently using a low‑acyl product (e.g., CP Kelco KELCOGEL CG‑LA) and want a less brittle texture, contact us for a customized blending recommendation or a sample of CAG high‑acyl grade.
