Xanthan gum is a natural polysaccharide derived from the fermentation of sugar by the bacterium Xanthomonas campestris. It is commonly used as a thickener, stabilizer, and emulsifier in a wide range of applications, including food, pharmaceuticals, and personal care products. Xanthan gum is valued for its ability to improve texture, maintain stability, and provide a consistent viscosity across different temperatures and pH levels.
Benefits of Xanthan Gum
- Thickening Agent: Xanthan gum is an effective thickener, providing viscosity and texture to various formulations.
- Stabilization: It helps stabilize emulsions, preventing separation of oil and water-based components.
- Consistency Across Temperatures: Xanthan gum retains its thickening properties across a wide range of temperatures, making it versatile in various applications.
- Emulsification: It aids in the emulsification process, allowing different ingredients to blend smoothly.
- Suspension Properties: Xanthan gum can keep solid particles suspended in liquids, ensuring consistent product distribution.
Common Uses of Xanthan Gum
Food and Beverages
Xanthan gum is widely used in the food industry for its thickening and stabilizing properties. Common applications and recommended usage percentages include:
- Sauces and Dressings: To provide a thick consistency and prevent separation, typically used at 0.1–1%
- Baked Goods: To improve texture and retain moisture, usually used at 0.1–0.5%
- Beverages: To maintain suspension and stability, generally used at 0.1–0.5%
Pharmaceuticals
In pharmaceuticals, xanthan gum is used for its thickening and stabilizing properties. Common applications include:
- Suspensions and Syrups: To maintain consistency and stability, generally used at 0.1–1%
- Topical Medications: To provide a stable and consistent texture
Personal Care and Cosmetics
Xanthan gum is used in personal care products for its thickening and stabilizing properties. It is commonly found in:
- Creams and Lotions: To add viscosity and stability, typically used at 0.1–1%
- Hair Care Products: To enhance consistency and stabilize formulations
- Toothpastes: To provide a smooth texture and prevent separation
