Xanthan gum powder Specifications
Xanthan gum is classified into four types, including food-grade, pharmaceutical-grade, refined chemical-grade, and industrial-grade.
Transparent xanthan gum is a versatile ingredient that functions as a thickener, suspending agent, and stabilizer with high transparency.
Food-grade xanthan gum is widely used in various industries as a salt- and acid-resistant thickener, suspending and emulsifying agent, and high-viscosity filling agent. It improves the water-retaining and shaping ability, freeze-thaw stability, taste, and shelf life of food products.
Xanthan gum is produced through fermentation of Xanthomonas campestris bacteria. Key steps include:
- Strain Selection: High-quality X. campestris strains are selected through domestication and purification.
- Culture: The selected strains are cultured in two stages - primary and secondary culture - under controlled temperature, oxygen, nutrients to multiply.
- Fermentation: The cultured strains are inoculated into fermentation tanks. Under optimal conditions, they are fermented for 70 hours to produce xanthan gum.
- Extraction: The fermented broth undergoes pretreatment. Ethanol/isopropanol is added to precipitate out crude xanthan gum fibers.
- Purification: The crude gum undergoes two-stage extraction and dewatering to purify it.
- Processing: The purified gum is pressed, dried into fibrous form then ground into powder of different mesh sizes.
- Quality Control: The powder is tested and classified according to specifications.
- Packaging and Shipment: The compliant powder is packaged and released to customers according to their requirements.
