Pullulan CAS 9057-02-7: From Fermentation to Applications – A Versatile Natural Polysaccharide
Release time: 2026-04-29
In the field of natural biological polysaccharides, Pullulan（CAS No.9057-02-7） has become a key raw material for cosmetics, food, pharmaceuticals, and eco-friendly packaging due to its unique molecular structure, excellent physical and chemical properties, and wide compatibility. As a natural polysaccharide produced by microbial fermentation, it is safe, non-toxic, biocompatible, biodegradable, and highly film-forming. Different from traditional chemical raw materials, pullulan aligns with the global corporate trends toward bio-friendliness, sustainable production, and green development.
With years of experience in the field of microbial polysaccharides, BLi-T Chemical is a reliable supplier of pullulan with mature fermentation technology, strict quality control, and global customer validation.
Natural Source & Fermentation Production
Pullulan is a water-soluble natural microbial polysaccharide biosynthesized by Aureobasidium pullulans via submerged liquid fermentation. The primary challenges in its production process include strain stability, the control of high-viscosity systems, and precise fermentation management.
Hóa chất BLi-T’s Advantage of Pullulan
- Strain Advantage: Self-screened high-yield strains verified for stability over 10 generations; fermentation yield 18% higher than industry average.
- Intelligent Large Scale Production: 100 m³ fermenter clusters with DCS system for real-time monitoring of dissolved oxygen, pH, temperature, and viscosity; fully automated feeding control.
- High Viscosity Technology: Custom agitators, multi stage ventilation, and gradient heating stabilize output at 55–60 g/L with pure white color and no browning.
- Green Post Processing: Closed loop process (filtration → concentration → alcohol precipitation → decolorization → spray drying → packaging); impurity removal 99.8%, whiteness ≥95.
- Full Chain Quality Control: Comprehensive testing and 3 year batch retention; full traceability by batch number.
- Green Production: ISO 14001 certified; wastewater COD removal rate >95%.
- Dual Purification: Membrane separation + gel filtration; purity ≥99%, heavy metals <0.1 ppm, no solvent residue.
Authoritative Certifications
- Food Grade: Complies with Chinese national food standards, third-party tested.
- Cosmetic Grade: Registered cosmetic raw material by NMPA.
- Pharmaceutical Grade: GMP certification in progress; applied in oral capsules.
- System Certifications: ISO 9001, ISO 45001.
