Ingredient Information
Summary
Gellan Gum is a food additive derived from bacteria, used as a gelling agent, thickener, and stabiliser. It’s commonly found in products like plant-based milks, desserts, and sauces to improve texture and consistency. Gellan Gum is particularly beneficial for those following vegan or vegetarian diets, as it provides a plant-based alternative to gelatine. It’s also useful for individuals with specific dietary needs, such as those requiring gluten-free or dairy-free options. Gellan Gum helps maintain the quality and appeal of various foods, making it a versatile ingredient in the food industry.

What Is Gellan Gum?
Gellan gum, also known as E418, is a polysaccharide used as a gelling agent. Its empirical formula is (C12H18O9)n. Classified as a hydrocolloid, it typically appears as a white to off-white powder. Gellan gum is produced through the fermentation of carbohydrates by the bacterium Sphingomonas elodea. It is commonly used in the food industry to stabilise, thicken, or gel products, offering a clear, firm texture. Notably, gellan gum is heat-stable and can form gels at low concentrations, making it versatile for various applications, including vegan and gluten-free products.
How It Works In The Body
Gellan gum is a food additive that acts as a stabiliser and thickener. It passes through the digestive system largely unchanged, as the body doesn’t break it down. It helps maintain the texture and consistency of foods without contributing to calorie intake.
Safety & Interactions
- Gellan gum is generally recognised as safe when used as a food additive in typical amounts.
- It is well-tolerated by most individuals, but excessive consumption may cause digestive discomfort, such as bloating or gas.
- There is no specific UK upper intake level for gellan gum, but it should be consumed in moderation as part of a balanced diet.
- Individuals with gastrointestinal sensitivities should monitor their intake, as gellan gum may exacerbate symptoms.
Always consult your health practitioner before taking nutritional supplements, especially if you are taking medication or are under medical supervision. You should not take supplements as a substitute for a varied balanced diet or healthy lifestyle.
