Does Xanthan Gum Contain Sugar?

Xanthan gum is a widely used food additive that serves as a thickening and stabilizing agent in many products. It is commonly found in sauces, dressings, and gluten-free baked goods. One question that often arises is whether xanthan gum contains sugar.

In this article, we will delve into the composition of xanthan gum and explore whether it is sugar-free or not.

Understanding Xanthan Gum

Xanthan gum is a polysaccharide, which means it is composed of multiple sugar molecules joined together. However, despite being made from sugars, xanthan gum itself does not contain any significant amounts of sugar.

It is derived through a fermentation process using a bacterium called Xanthomonas campestris, which feeds on carbohydrates like glucose or sucrose. The bacteria produce the xanthan gum as a natural byproduct of their metabolic activities.

Composition of Xanthan Gum

Xanthan gum consists of repeating units of sugar molecules, specifically glucose, mannose, and glucuronic acid. These sugar molecules are linked together in a complex structure, creating a long-chain polymer. The unique arrangement of these sugar units gives xanthan gum its remarkable thickening and stabilizing properties.

Sugar Content in Xanthan Gum

While xanthan gum is derived from sugar sources, it undergoes extensive processing during production, which removes the majority of the sugar. As a result, the final product contains an insignificant amount of sugar. Therefore, xanthan gum can be considered virtually sugar-free.

Uses of Xanthan Gum

Xanthan gum is widely used in the food industry due to its various functional properties. Here are some of its common applications:

Thickening Agent:

Xanthan gum has excellent thickening abilities. It can enhance the viscosity of liquids, giving them a smoother and more appealing texture. This property makes it a popular ingredient in salad dressings, sauces, and gravies. For example, when added to a salad dressing, xanthan gum creates a creamy and consistent texture that coats the vegetables evenly.


Xanthan gum helps prevent ingredients from separating or settling in food products. It keeps the components well-mixed and maintains their uniform consistency over time. This property is particularly beneficial in dairy products and beverages.

For instance, in yogurts, xanthan gum ensures that the fruit pieces or flavorings remain evenly distributed throughout the product, avoiding any separation or settling.

Gluten Substitute:

Xanthan gum is a common ingredient in gluten-free recipes as it provides elasticity and structure to baked goods. It mimics the role of gluten, allowing gluten-sensitive individuals to enjoy foods that would typically contain wheat flour.

When used in gluten-free bread, xanthan gum acts as a binding agent, giving the dough a stretchy texture and helping it rise.

Suspension Agent:

Xanthan gum can suspend solid particles in liquids, preventing them from sinking to the bottom. This property is valuable in beverages with added pulp or fruit pieces. For example, in fruit juices with pulp, xanthan gum helps keep the pulp evenly distributed throughout the liquid, giving it a consistent texture and preventing settling.


Xanthan gum can stabilize emulsions, preventing oil and water from separating. This property makes it useful in salad dressings, mayonnaise, and other oil-in-water emulsions.

When added to a salad dressing, xanthan gum ensures that the oil and water components remain well-blended and do not separate, resulting in a smooth and creamy dressing.

Benefits of Xanthan Gum

Apart from its functional properties, xanthan gum offers several benefits in food production and consumption:

Lower Calorie Content:

Since xanthan gum is virtually sugar-free, it adds minimal calories to the final product. It is an ideal ingredient for those aiming to reduce their sugar intake without compromising on the texture or taste of their favorite foods. This makes it a suitable option for individuals on a calorie-controlled diet or those with diabetes.

Improved Shelf Life:

Xanthan gum helps extend the shelf life of certain food products by enhancing their stability. It prevents syneresis, which is the separation of liquid from a gel-like substance, keeping the product fresh for a longer period.

For example, in a gel-based dessert, xanthan gum prevents the liquid portion from separating and forming a watery layer on top, maintaining the dessert’s quality and appearance for a longer time.

Enhanced Texture:

Due to its thickening abilities, xanthan gum contributes to the desirable texture of various food items. It adds body and mouthfeel, making them more enjoyable to consume.

In a creamy soup, xanthan gum acts as a thickener, giving the soup a velvety texture that coats the palate and enhances the overall eating experience.

Gluten-Free Alternative:

Xanthan gum plays a crucial role in gluten-free baking, allowing individuals with gluten sensitivities or celiac disease to indulge in a wider range of delicious treats.

It helps create a structure and elasticity in gluten-free dough, preventing it from being crumbly and ensuring a more pleasant texture in the final baked goods.


In summary, xanthan gum, although derived from sugars, does not contain a significant amount of sugar. It is a polysaccharide that functions as a sugar-free thickening and stabilizing agent in various food products.

Its unique chemical composition and properties make it a valuable ingredient in the food industry. Whether you are looking to add thickness to your favorite sauce or need a gluten substitute in your baking, xanthan gum can be a beneficial addition to your pantry.
