Why Food Manufacturers Are Switching to Gellan Gum

Gellan gum, known for its exceptional gelling properties, is a highly versatile food hydrocolloid used in various food applications. This natural product, often replacing agar and carrageenan, is well-suited for diverse food formulations. Let's explore its unique qualities and benefits for food manufacturers.

 

Why Choose Gellan Gum?

With its exceptional gelling power, gellan gum achieves equivalent gel strength at just 0.25% usage- far lower than agar (15% required) or carrageenan (1% needed). This superior efficiency has made it the preferred choice to replace traditional hydrocolloids in food applications.

Key Advantages:

✔ Extremely low dosage (0.05–0.4%) for high gel strength

✔ Excellent compatibility with xanthan gum, guar gum, locust bean gum, gelatin, and alginate

✔ Synergistic effects to create superior thickeners and stabilizers

✔ Cost-effective reformulation for manufacturers

 

 

Low-Acyl Gellan Gum Gel Properties Overview

Property	Function
Effective at Extremely Low Usage	Gellan gum is a highly efficient gelling agent, even at low concentrations.
Usage Range (0.05~0.4%)	Gellan gum is effective within a typical usage range of 0.05% to 0.4%.
High Transparency of Gel	Gellan gum forms gels with excellent transparency, meeting the needs of high-clarity food products.
Stability in Acidic Conditions	The gel is stable under acidic conditions, especially in pH ranges of 4.0 to 7.5, extending shelf life of acidic food products.
Control of Gelation Temperature	The type and concentration of ions can be adjusted to control gelation and melting temperatures.
Delayed Gelation and Melting	Gellan gum has a delayed gelation and melting behavior, allowing for the creation of both thermoreversible and thermirreversible gels.
Good Heat Stability	The gel exhibits excellent heat stability, withstanding high-temperature processes like heating, sterilization, and cooking.
Compatibility with Other Hydrocolloids	Gellan gum is highly compatible with other hydrophilic gums, allowing for various gel textures and stable formulations.
Flavor Release	The gel structure provides an optimal medium for flavor release, helping to develop new textures, appearances, or flavors.
Good Suspension Properties	Weak gels formed by gellan gum exhibit excellent suspension properties, making it ideal for use as a premium suspension agent.

 

Comparison of Gellan Gum with Other Hydrocolloids

High-acyl Gellan Gum and Low-acyl Gellan Gum have significant differences in gel texture. High-acyl Gellan Gumforms elastic gels, while Low-acyl Gellan Gum forms hard and brittle gels, each with distinct gelling properties and functions. Combining both in different ratios can create unique effects.

 

Extremely Low Usage: One unique advantage of Gellan Gum is that it can perform gelation at very low concentrations. Its usage is typically 1/3 to 1/2 of K-carrageenan or 1/5 of Agar. For example, to form a gel, Gellan Gum is typically used in the range of 0.05% to 0.4%.

Excellent Gelation Ability: Gellan Gum allows for easy gel formation. Compared to other food gums, Gellan Gum exhibits excellent gelation capabilities. It can form gels more efficiently, create more diverse gel textures, and even form dehydrated gels that can rehydrate and return to their original form.

 

Compared to agar and kappa-carrageenan, gellan gum is a far more efficient gelling agent. At the same concentration, Gellan Gum generates a higher gel modulus and hardness compared to other water-soluble gels. Alternatively, to achieve the same modulus and hardness, Gellan Gum requires a smaller amount, clearly demonstrating its greater effectiveness.

 

Top Gellan Gum Applications in Food & Beverage

Gellan gum delivers exceptional performance across pre-processed, ready-to-eat, and dry-mix products, offering easy hydration and gel formation. It has demonstrated significant advantages, especially in high-solid products, fruit-based products, beverages, desserts, imitation foods, and dairy products. Its versatility supports innovative product development and adapts to evolving consumer demands.

 

• Gellan Gum in High-Solid Products

In high-solid products, gellan gum is often blended with other hydrophilic colloids such as starch, pectin, and gelatin to enhance the texture and stability of products. For example, in starch-based jellies and gummy candies, gellan gum reduces gelling time, allowing quicker product removal from molds and improving production efficiency. It also enhances the texture and appearance of the product. Gellan gum increases the heat stability of gelatin-based gummies, enabling the product to maintain its stability at higher temperatures. Additionally, it can be used independently to create unique textures and excellent flavor release in gummies.

 

• Gellan Gum in Fruit Jams And Jellies

In fruit-based products, gellan gum is an ideal alternative to other gelling agents, especially in low-sugar fruit jams and jellies. While high-methoxyl pectin requires careful pH control and a high-sugar environment to form gels, gellan gum provides better stability and storage properties in low-sugar environments. Its use ensures that products remain stable in both transportation and storage, maintaining the desired texture and appearance.

 

• Gellan Gum in Beverages

For beverages, gellan gum showcases the advantages of fluid gel technology. In suspension beverages, low-acyl gellan gum can create a clear and uniform suspension at very low usage levels (as low as 0.012%). This technology enables the suspension of fruit pulp, juice, and other small particles without adding a heavy "gummy" texture, improving the drink's natural taste and appearance. In fruit juice beverages, low-acyl gellan gum at 0.3% helps achieve a consistent and visually appealing appearance, ensuring the even distribution of pulp.

 

 

• Gellan Gum in Dessert

In dessert products, gellan gum's heat stability and excellent flavor-release properties make it ideal for water-based gelled desserts. By adjusting the amount of gellan gum used, manufacturers can modify the gel characteristics, extending the melt time and ensuring the product remains stable even in relatively high-temperature environments.

In applications like pie fillings and puddings, gellan gum enhances the texture and stability of these foods. Traditionally, starch or starch-protein mixtures were used to provide the required texture for pie fillings and puddings, but gellan gum improves the stability and texture significantly. It also enhances the sensory qualities of the final product.

 

• Gellan Gum in Dairy

In dairy products, gellan gum can replace other gelling agents, such as carrageenan, gelatin, seaweed gel, and pectin, offering better gel formation and consistency. It hydrates directly in dairy at temperatures as low as 75°C and can be used in acidic dairy products like yogurt or acidified cream. Gellan gum needs to be combined with other colloids like CMC or guar gum to prevent protein precipitation in these applications.
