Mechanisms of Thickening

Exploring xanthan gum thickener’s world is fascinating. It changes liquids through complex chemical actions that change food and industrial products.

Liquid Transformation Process

Xanthan gum changes liquid viscosity in amazing ways. Its polymer chains form complex networks that alter liquid behavior¹². Studies show xanthan gum solutions have unique traits at different concentrations:

Below 0.75 g/L, they act like typical viscoelastic liquids¹²
At 0.75 g/L, they might form aggregates¹²
Above 0.75 g/L, they behave like gels¹²

Pseudoplastic Behavior Explained

Xanthan gum has a special property called pseudoplasticity. When it faces shear stress, its viscosity drops a lot¹². This means it gets thinner when mixed or shaken, but returns to its original thickness when stress is gone.

Studies show xanthan gum’s viscosity is interesting. At 90°C, its viscosity is 121.7 mPa·s, which is lower than some hydrocolloids¹³. Its viscosity stays around 60.70% at high temperatures, showing it’s very stable¹³.

Comparing Xanthan Gum with Other Thickeners

It’s important for food scientists and industrial formulators to know the differences between xanthan gum substitutes. Each thickener has its own special properties. These can greatly affect how a product works xanthan gum alternatives need to be chosen wisely for each use.

Viscosity and Performance Comparisons

Xanthan gum is very versatile in thickening things. Studies have shown interesting facts about its performance¹⁴:

At 35℃, 1% concentrations of xanthan gum and guar gum showed similar viscosity¹⁴
Xanthan gum has unique shear-thinning characteristics more than guar gum¹⁴

Industrial and Culinary Applications

Different xanthan gum substitutes are better for different uses. Guar gum, for example, is cheaper and great at holding water¹⁵. It’s used in many fields, from oil and gas to textiles¹⁵.
