Learn about the properties, benefits, and uses of gellan gum in food and beverage applications
Gellan gum is a natural food additive that is commonly used in the food and beverage industry to improve texture, stability, and appearance. In this article, we'll explore what gellan gum is, how it works, and some of its key benefits and uses.
What is Gellan Gum?
Gellan gum is a polysaccharide produced by fermentation of the bacteria Sphingomonas elodea. It is a high molecular weight polymer that can form gels and thicken solutions at low concentrations, making it an effective alternative to traditional thickeners and stabilizers.
Gellan gum is a natural ingredient, produced through a process of fermentation of a carbohydrate substrate. It is commonly used in vegan and vegetarian food products as a plant-based alternative to animal-derived thickeners and stabilizers.
How Does Gellan Gum Work?
Gellan gum works by forming a network of long, thin strands that create a three-dimensional structure. This structure can trap water, creating a gel or thickened solution. The network of strands is stabilized by calcium ions, which cross-link the strands together.
Gellan gum can be used to create a wide range of textures, from soft and delicate to firm and elastic. The texture is determined by the concentration of gellan gum used, as well as the presence of other ingredients such as sugars and salts.

Gellan gum offers a range of benefits for food and beverage manufacturers, including:
Versatile functionality: Gellan gum can be used to create a wide range of textures, including gels, suspensions, and foams. It is also compatible with a range of other ingredients and can be used in a variety of applications.
Clean-label appeal: Gellan gum is a natural ingredient, produced through a fermentation process. It is therefore considered a clean-label ingredient, and can be used in organic and natural foods.
High stability: Gellan gum is highly stable, even in challenging conditions such as high temperatures and acidic environments. This makes it a reliable choice for food and beverage manufacturers looking to create products with a long shelf-life.
Cost-effective: Gellan gum is an effective thickener and stabilizer at low concentrations, making it a cost-effective choice for food and beverage manufacturers.
Uses of Gellan Gum
Gellan gum has a wide range of uses in food and beverage applications, including:
Dairy products: Gellan gum can be used to stabilize and thicken dairy products such as yogurt, ice cream, and cheese.
Beverages: Gellan gum can be used to thicken and stabilize beverages such as juice, sports drinks, and smoothies.
Bakery products: Gellan gum can be used to improve the texture and stability of baked goods such as cakes, muffins, and bread.
Sauces and dressings: Gellan gum can be used to create stable and smooth sauces and dressings.
Safety of Gellan Gum
Gellan gum is generally recognized as safe by regulatory agencies such as the U.S. Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA). It is not known to cause any adverse health effects when used in food and beverage applications.
However, as with any food additive, it is important to use gellan gum in accordance with applicable regulations and guidelines. Some people may be allergic or sensitive to gellan gum, and it is important to carefully monitor the use of gellan gum in products intended for sensitive populations.
