What is Curdlan Gum?
Curdlan is a linear beta-1,3-glucan polysaccharide that is produced by certain types of bacteria, including Agrobacterium and Alcaligenes faecalis. It forms a gel-like substance when heated in water, making it useful as a thickening and gelling agent in food products. Curdlan has a high viscosity, and its ability to form strong gels makes it an attractive alternative to other polysaccharides, such as agar and carrageenan.
Curdlan is also being studied for its potential medical applications. It has been shown to stimulate the immune system and may have anti-tumor properties. Additionally, curdlan has been used as a drug delivery system, as it can form stable complexes with drugs and release them slowly over time.
Origin
Curdlan gum is a polysaccharide that is produced by certain types of bacteria, including Agrobacterium and Alcaligenes faecalis. These bacteria naturally produce curdlan as a part of their cell walls. The discovery of curdlan dates back to the 1960s, when it was first isolated from Agrobacterium and found to have unique gel-forming properties.
Since then, curdlan has been studied extensively for its various applications, including as a food additive, a drug delivery system, and a potential immunostimulatory and anti-tumor agent. Curdlan is commercially produced through fermentation of the bacteria in large-scale bioreactors, followed by purification to obtain the final curdlan gum product.
Commercial Production of Curdlan Gum
Curdlan is commercially produced through a fermentation process using specific strains of bacteria such as Agrobacterium species, Alcaligenes faecalis, and Rhizobium radiobacter. The production process involves the following steps:
- Inoculation: The bacteria are grown in a nutrient-rich medium under sterile conditions. The culture is then transferred to a larger fermenter to increase the biomass.
- Fermentation: The bacteria are allowed to grow and produce curdlan in a large-scale fermenter containing a medium that provides optimal growth conditions. This can take several days, during which time the temperature, pH, and oxygen levels are carefully controlled.
- Harvesting: Once the curdlan production has reached its peak, the bacterial cells are harvested and separated from the fermentation broth.
- Purification: The curdlan is then purified by treating the cells with acid to dissolve the cell wall and release the curdlan. This is followed by several rounds of filtration, centrifugation, and washing to obtain the pure curdlan gum.
- Drying: The final step involves drying the curdlan gum to a low moisture content and converting it into a powder form suitable for commercial use.
The purity, molecular weight, and degree of branching of the curdlan gum can be modified during the production process to achieve specific functional properties that make it suitable for various applications, including as a food additive, drug delivery system, and biomedical material.
Function
Curdlan has several functional properties that make it useful for various applications. Some of its functions include:
- Gelling agent: Curdlan can form a gel-like substance when heated in water, making it useful as a gelling agent in food products. Its ability to form strong gels makes it an attractive alternative to other polysaccharides, such as agar and carrageenan.
- Thickener: Curdlan has a high viscosity and can be used as a thickener in various food products, including sauces, soups, and dressings.
- Stabilizer: Curdlan can help stabilize food products by preventing separation of ingredients or preventing ice crystal formation in frozen foods.
- Drug delivery system: Curdlan can form stable complexes with drugs and release them slowly over time, making it a potential drug delivery system for various applications.
- Immunostimulant: Curdlan has been shown to stimulate the immune system, making it a potential therapeutic agent for various immunological disorders.
- Anti-tumor agent: Curdlan has been shown to have anti-tumor properties in animal studies, making it a potential candidate for cancer therapy.

Curdlan Gum Application
Curdlan has a wide range of applications in the food industry, biomedical field, and other industries. Some of the applications of curdlan include:
Curdlan has several applications in the food and beverage industry due to its unique gelling, thickening, and stabilizing properties. Some of its applications include:
- Gelling agent: Curdlan can be used as a gelling agent to form gels in food products such as desserts, jellies, and gummies. Its gelling properties make it an attractive alternative to other gelling agents such as agar and carrageenan.
- Thickener: Curdlan can be used as a thickener in various food products, including soups, sauces, and gravies. Its high viscosity and stability make it a suitable alternative to other thickeners such as cornstarch and flour.
- Stabilizer: Curdlan can help stabilize food products by preventing separation of ingredients or preventing ice crystal formation in frozen foods. This makes it useful in products such as ice cream, frozen desserts, and whipped toppings.
- Texture modifier: Curdlan can be used to modify the texture of food products, including improving the mouthfeel of low-fat or low-calorie foods.
- Fat replacer: Curdlan can be used as a fat replacer in food products, including baked goods and dairy products. It can improve the texture and mouthfeel of low-fat or reduced-fat products.
- Gluten-free alternative: Curdlan is gluten-free and can be used as a substitute for wheat flour in gluten-free products such as bread, pasta, and crackers.
Overall, the unique functional properties of curdlan make it a versatile and promising material for various applications across different industries.

Great customer service
Great customer service , looking forward to order again
Good
We ordered 500 kg of curdlan gum from Ingerland and received the package just yesterday. The packaging was nice, but it took 14 days to deliver. The customer support team was helpful and responsive throughout the process.
