Gellan gum is a polysaccharide produced by the bacterium Sphingomonas elodea when it feeds on lactose or glucose. First approved for food use in the 1990s, it initially replaced gelatin and agar in products like jellies, partly to accommodate religious dietary restrictions around animal-derived ingredients. Once manufacturers recognized its broader advantages over traditional hydrocolloids, adoption spread rapidly across the food industry.
Listed as E418 on European food labels, gellan gum is valued for its low dosage requirements, high gel transparency, strong aroma release, and stability across a wide pH range. It comes in two formulations, high-acyl and low-acyl, each suited to different texture and processing needs.
High-Acyl vs. Low-Acyl Gellan Gum
High-acyl gellan gum forms soft, elastic gels. This makes it suitable for delicate suspensions and applications where a firmer gel would damage fragile particles or compromise mouthfeel. It works well in dairy desserts, puddings, and soft confections where a smooth, creamy texture is desired.
Low-acyl gellan gum (LAG) produces hard, brittle gels that withstand heat better. Even at very low concentrations, it achieves high gel strength, which enables innovations like shapeable plant-based proteins. Adding cations such as calcium, magnesium, or sodium enhances the gelation of both types.
Beverage Stabilization and Suspension
One of the most common applications of gellan gum is in beverages. It suspends pulp, fiber, protein particles, and other ingredients evenly throughout a drink, preventing settling during storage. Orange juice manufacturers use it to keep pulp dispersed, while protein- and fiber-enriched drinks rely on it to maintain a uniform consistency.
Gellan gum also contributes to mouthfeel in beverages without adding excessive viscosity. Fruit-flavored milk drinks, plant-based milks, and nutritional shakes all benefit from its ability to keep ingredients suspended while maintaining a clean, drinkable texture.
Bakery, Dairy, and Noodle Products
In noodle products such as Chinese noodles, soba noodles, and cut noodles, gellan gum enhances hardness, elasticity, and viscosity. It improves mouthfeel, inhibits swelling in hot water, reduces breakage, and decreases soup turbidity. The typical dosage is 0.1 to 0.3 parts per thousand of wheat flour weight.
In ice cream, gellan gum improves shape retention during serving and storage. When added to cakes and cheese cakes, it provides moisturizing, freshness-preserving, and shape-retaining effects. For dairy applications, it works especially well when combined with other stabilizers to achieve target textures.
Plant-Based and Clean-Label Innovation
Gellan gum has become an essential tool for plant-based food development. It helps create veggie burgers that hold together during cooking, plant-based cheese that melts properly, and dairy-free desserts with satisfying textures. Because it is produced through microbial fermentation rather than animal sources, it aligns with vegan and vegetarian product requirements.
Its compatibility with other food gums allows manufacturers to fine-tune texture and stability in complex formulations. Gellan gum can also modify starch behavior for improved textural characteristics and shelf stability, making it useful in ready-to-eat meals and convenience foods.
