Gellan gum is a versatile, plant-based gelling agent that revolutionizes modern food science and various industrial applications. Derived primarily from the bacterium Sphingomonas elodea, this biopolymer is celebrated for its unique texture-enhancing properties in food, pharmaceuticals, and cosmetic industries.
Origins and Production
Sphingomonas elodea, a naturally occurring bacterium, is the source of gellan gum. Cultivated typically in controlled fermentative environments, this microorganism produces gellan gum when glucose, a simple sugar, is converted through a sophisticated microbial fermentation process. This fermentation is carefully monitored to ensure the purity and consistency of the gellan gum produced.
Industrial Cultivation
The production of gellan gum involves several key steps. Initially, the bacterial culture is grown in large aerated fermenters that contain a nutrient-rich broth. Optimal growth conditions such as temperature, pH, and nutrient concentrations are meticulously maintained to maximize the yield of gellan gum. After fermentation, the broth is subjected to precipitation using isopropyl alcohol, followed by drying and milling to produce the refined gellan gum powder that is used commercially.
Properties and Characteristics of Gellan Gum
Gellan gum is a biopolymer that serves as a multifaceted additive in numerous industries due to its exceptional gelling, stabilizing, and texturizing properties. Here is a detailed overview of its unique characteristics and applications:
Gelling Properties
Gellan gum is highly valued for its superior gelling capabilities. When dissolved in water and cooled, it forms gels that are clear, robust, and can be tailored in texture from soft and elastic to firm and brittle, depending on the concentration used and the presence of ions like calcium or magnesium.
- Thermal Reversibility: The gels formed by gellan gum are thermoreversible, meaning they can melt upon heating and reform upon cooling, which is advantageous for foods that need to be reheated or reshaped.
- pH Stability: It remains stable across a wide pH range, from acidic to neutral environments, making it suitable for diverse food products, including acidic jams and dairy-based desserts.
Thickening and Stabilizing Abilities
As a thickening agent, gellan gum improves the viscosity and texture of solutions even at low concentrations, which is essential for sauces, soups, and creams.
- Suspension Capabilities: It effectively suspends particles in beverages, preventing the settling of ingredients in plant-based milks and fortified drinks.
- Synergy with Other Hydrocolloids: Gellan gum works synergistically with other gums and thickeners, enhancing its functionality in complex formulations.
Applications Across Industries
Due to these properties, gellan gum is not just limited to food products; it also extends to pharmaceuticals and cosmetics.
- Food Industry: In foods, it is used to stabilize emulsions and foams, control ice crystal formation in frozen products, and improve the mouthfeel of beverages and desserts.
- Pharmaceuticals: In the pharmaceutical industry, gellan gum serves as a controlled-release matrix in capsules and tablets.
- Cosmetics: For cosmetics, it provides a stable base for lotions and creams, enhancing their texture and moisture retention.
Brand Assurance and Quality
Companies like SHINE, a leading brand in the production of high-quality gellan gum, ensure that all these properties are consistently met. SHINE employs advanced production techniques and rigorous quality control measures to deliver gellan gum that not only meets but exceeds industry standards.

Versatility in Applications of Gellan Gum
The functionality of gellan gum extends beyond mere gelling. It is also used to stabilize emulsions and suspend particulates in solutions, which is crucial in products like fortified plant-based milks and sauces. Its ability to form fluid gels that can be sheared and revert back to their original state is particularly valuable in industrial applications that require precise texture and viscosity control.
- Food and Beverage: Enhances texture and stability in products like jellies, plant-based milks, and sauces, ensuring a consistent and enjoyable consumer experience.
- Pharmaceuticals: Utilized in controlled-release drug formulations, gellan gum aids in the precise delivery of medications, increasing their efficacy and safety.
- Cosmetics: Acts as a stabilizer and thickener in lotions and creams, improving product consistency and user satisfaction.
- Industrial Products: Used in non-food items such as lubricants and adhesives, providing improved performance and reliability.
- Research and Development: Supports scientific advancements in biotechnology and materials science, especially in hydrogel research for medical applications.
