Hydrocolloid: Xanthan Gum

Xanthan Gum: The Microbial Polysaccharide Revolutionizing Modern Gastronomy

Xanthan Gum, a polysaccharide secreted by the bacterium Xanthomonas campestris, has become a staple in both the food and non-food industries due to its exceptional thickening, stabilizing, and emulsifying properties. But what's the scientific foundation behind this hydrocolloid's behavior, and how has it been seamlessly integrated into contemporary cuisine?

Historical Context

The discovery of Xanthan Gum dates back to the 1960s when researchers were exploring the potential of microbial polysaccharides. It was subsequently commercialized and has since become a favored ingredient in various applications¹.

The Molecular Science of Xanthan Gum

Xanthan Gum is a high molecular weight polysaccharide, comprising repeating units of glucose, mannose, and glucuronic acid². Its unique helical structure and ability to form a weak gel in aqueous solutions make it a versatile thickening agent.

Production and Refinement

Xanthan Gum is produced through fermentation using Xanthomonas campestris. After fermentation, the broth is pasteurized and then precipitated using isopropanol to yield the gum. It then undergoes drying and milling processes to produce a fine powder³.

A Multifaceted Ingredient

Xanthan Gum's versatility is evident in its wide range of applications:

• Food Industry: Used as a thickener, stabilizer, and emulsifier in various food products⁴.

• Cosmetics: Employed for its rheological properties in formulations⁵.

• Pharmaceuticals: Incorporated as a binder and suspending agent in drug formulations⁶.

Xanthan Gum in Culinary Creations - Proportions

Xanthan Gum's culinary proportions are dictated by its potent thickening capabilities:

1. Sauces and Dressings:

   • Proportion: 0.1% to 0.5% of the total weight⁷.
   • Purpose: Provides stability and a smooth texture.

2. Baked Goods:

   • Proportion: 0.1% to 0.5% of the total weight⁸.
   • Purpose: Improves moisture retention and extends shelf life.

3. Dairy Products (like Ice Cream):

   • Proportion: 0.2% to 0.5% of the total weight⁹.
   • Purpose: Prevents ice crystal formation and enhances mouthfeel.

4. Beverages:

   • Proportion: 0.05% to 0.3% of the total weight¹⁰.
   • Purpose: Provides a thicker, richer mouthfeel.
