Xanthan Gum Manufacturing Process

Xanthan Gum is a common food ingredient that is being used in many different types of food products. It is a versatile ingredient used in many industries, from food and beverage to pharmaceuticals and cosmetics. Its unique properties make it ideal for thickening, stabilizing and suspending a wide range of products. But what exactly is xanthan gum, and how is it manufactured? In this blog post, we will explore the xanthan gum manufacturing process and what goes into making this amazing ingredient.

What is Xanthan Gum?

Xanthan gum is a natural, sugar-like carbohydrate derived from the fermentation of glucose. It is commonly used as a thickening and stabilizing agent in the food industry. It is also used to improve the texture, consistency, and shelf life of certain products. Xanthan gum is created when a bacterial strain, often Xanthomonas Campestris, is allowed to ferment a sugar-containing solution.

There are many ways that xanthan gum is used in food products.

Thickening agent

The most common application of Xanthan gum is as a food additive, where it is used to create a smoother texture and enhance shelf life. It is often used as a thickening agent in baked goods, salad dressings, sauces, and condiments.

Stabilizer and Emulsifier

Xanthan gum is also used to improve the texture of foods. It is used as an emulsifier and stabilizer in dressings and sauces, and to help create a more consistent texture in baked goods.

How is Xanthan Gum Manufactured?

Xanthan gum is produced through a process of fermentation, concentration, and purification.


The first step involves the fermentation of glucose or sucrose by the bacteria, which produces a slimy substance. This substance is then concentrated and purified, resulting in the production of a fine powder.

The fermentation process is carried out in large tanks, where bacteria are allowed to grow and produce the slimy substance. After the fermentation process is complete, the substance is removed from the tanks and dried in a controlled environment. This drying process results in the formation of a powder, which is then purified and concentrated to obtain the desired viscosity.

Concentration and Purification

The concentration process involves the addition of a number of chemicals, such as sodium chloride, calcium chloride, and sodium hydroxide. These chemicals are used to adjust the pH level and viscosity of the substance. The purity of the powder is then determined based on the levels of these chemicals.

Once the powder has been produced, it is then dried and blended with other ingredients. This process is used to obtain the desired viscosity and texture. Finally, the powder is milled, sieved, and packaged for sale.
