A high–molecular-weight polysaccharide gelling agent produced by microbial fermentation and supplied as a purified, dried powder. This gellan gum (plant gel) disperses in cold water (dispersion aided by warm/hot water) and forms clear, rigid gels with excellent thermal stability and no syneresis. Gelation is reversible: melts at approximately 80–100°C and sets between about 10–50°C. The material is pH-tolerant across a wide range (pH 3–10) and gelation is promoted in the presence of calcium ions (e.g., calcium chloride).
Key features
- High molecular weight (~500,000 Da) polysaccharide
- Disperses in cold water; faster with warm/hot water
- Melting range: ~80–100°C; gelling range: ~10–50°C
- Clear, firm gels with minimal syneresis or weeping
- pH stability across pH 3–10
- Calcium-activated gelation (compatible with CaCl2)
- Good compatibility with natural additives and flavours
Typical applications
- Microbiology and plant tissue culture nutrient media (can be used as an agar replacement)
- Confectionery: jellies, jams, candy coatings, icing
- Beverages and gels
- Dairy and frozen desserts (where thermal stability and clarity are needed)
- Bakery fillings and frostings
- Pet food texture systems
Handling and storage
- Store in a cool, dry place in a tightly sealed container to prevent moisture uptake.
- Dispersion is easier if hydrated in warm water; avoid prolonged exposure to high temperatures beyond melting point.
- For formulations requiring stronger gels, trial combinations with calcium salts (e.g., calcium chloride) and adjust concentrations based on target texture.
Benefits for B2B buyers
- Consistent rheology and thermal stability suitable for industrial food and laboratory uses
- Clear, stable gels reduce processing issues related to weeping or syneresis
- Versatile pH tolerance and ionic responsiveness make it adaptable across diverse formulations
