Gellan Gum

What is Gellan gum?

Gellan gum ‌ is a kind of polysaccharide produced by microbial fermentation. The main components are glucose, glucuronic acid and rhamnose in a ratio of 2:1:1. It has good gel properties, can form a solid gel at a very low concentration, and is sensitive to shear force and melts in the mouth. Gellan gum is insoluble in non-polar organic solvents and cold water, but can be dissolved in water to form a transparent solution after heating, and form a transparent gel after cooling. ‌

Gellan gum dry powder is beige, no special taste and smell, about 150℃ without melting and decomposition. Good heat and acid resistance, high stability to enzymes. ‌

Advantage:

● Excellent gel properties: Gellan gum can produce gel at a very low amount of use, 0.25% of use can achieve the gel strength of AGAR 15% of use and carrageenan 1% of use.

● Good stability: Gellan gum acid resistance, high temperature resistance, heat reversibility, can resist the action of microorganisms and enzymes. It is stable under pressure cooking and baking conditions and performs best at pH 4.0-7.5.

● Wide range of applications: Gellan gum is widely used in many fields such as food, medicine and cosmetics. In food, it can improve the texture and taste of food, extend the shelf life; In medicine, as pharmaceutical excipients, it can extend the release time of drug ingredients; In cosmetics, it has a good moisturizing effect.
