Gellan

Gellan gum is a water-soluble polysaccharide produced by the bacterium *Sphingomonas elodea*. It's utilized extensively as a gelling, thickening, and stabilizing agent across various industries. The gelling properties arise from its unique molecular structure, forming a strong, transparent gel even at low concentrations. It exhibits thermal stability, remaining effective across a broad temperature range, and is resistant to degradation by enzymes, making it a versatile ingredient in food, pharmaceuticals, and industrial applications. Its ability to produce different textures, from firm to elastic, depending on the preparation method and concentration, further enhances its utility.

Gellan meaning with examples

• In the food industry, gellan gum is a common ingredient. It acts as a stabilizer in plant-based milk, preventing the sedimentation of particles and thickening sauces. Its usage allows for the creation of clear fruit jellies, providing the desirable texture. Further uses include making low-calorie jams, and coating candies to prevent sticking. It is also found in vegan products, offering a satisfying texture.
• Pharmaceutical companies often employ gellan gum. It's used as a matrix for controlled-release drug delivery systems, releasing the medication over time. It's also utilized in preparing sterile agar plates for microbial cultures. It is employed in the making of oral care products and as a binder for tablet formulations. Its biocompatibility and non-toxicity make it well suited for this use.
• The biotechnology sector utilizes gellan gum in various applications. It provides a supportive matrix for plant cell cultures, promoting growth and differentiation. It is also applied to encapsulate cells or bioactive compounds. Hydrogels made from the gum are used in tissue engineering, providing a scaffold for cellular growth. Its utility lies in its ability to mimic the extracellular matrix.
• The cosmetic industry finds many uses for gellan gum. It acts as a suspending agent in cosmetic formulations, preventing the settling of solid particles. It provides the creaminess in lotions and moisturizing gels. It is included in face masks for thickening and texture modification. Its benefits include enhancing product stability and giving a smooth texture.
• In industrial applications, gellan gum can be utilized. It is often a thickening agent for printing inks, improving their viscosity and flow characteristics. It also stabilizes paints and coatings and can be found in the creation of certain industrial adhesives. Further, it is used in the creation of specialized cements. It benefits many of the manufactured goods we consume.
