Product Description
Pullulan (CAS 9057-02-7) Edible Films and Coatings for Confections
Pullulan (CAS 9057-02-7) is a natural, water-soluble polysaccharide produced by the fungus Aureobasidium pullulans through fermentation. This neutral linear polymer composed primarily of maltotriose units linked by α-1,6 glycosidic bonds provides excellent film-forming, adhesive, and oxygen-barrier properties. Pullulan is odorless, tasteless, non-toxic, and biodegradable, making it an ideal biopolymer for food, pharmaceutical, and packaging applications.

Product Functions
- Film-forming: Creates strong, clear, flexible films with excellent gloss and smoothness
- Oxygen barrier: Low oxygen permeability makes it suitable for protective packaging of oxygen-sensitive products
- Edible coatings: Safe for direct food contact; used for edible films and capsules
- Stabilizer and binder: Improves texture and stability in food and pharmaceutical formulations
- Adhesive properties: Acts as a natural adhesive in various applications
- Encapsulation: Used in microencapsulation for flavors, probiotics, and sensitive actives
- Controlled release: Enables controlled release formulations in pharmaceuticals and nutraceuticals
- Moisture barrier and anti-caking agent in formulations
Application Areas
Food Industry
- Edible films and coatings for confections, bakery products, and fresh produce
- Low-fat and fat-replacement applications to improve mouthfeel and texture
- Carrier and encapsulant for flavors, vitamins, and probiotics
Pharmaceutical and Nutraceutical
- Fast-dissolving and pullulan-based capsules (suitable for vegan/vegetarian capsules)
- Tablet binder, film-coating, and controlled-release matrices
- Encapsulation of probiotics and sensitive actives for stability
Cosmetic and Personal Care
- Film-forming agents in face masks, peel-off formulations, and hair products
- Stabilizer and texture modifier in creams and serums
Packaging and Coatings
- Biodegradable films with good oxygen barrier for food packaging
- Laminates and coatings to improve shelf life of packaged goods
Adhesives and Industrial Uses
- Specialty adhesives, laminates, and paper coatings
Biotechnology and Research
- Matrix for cell culture, microencapsulation, and analytical applications
Manufacturing Process Overview
- Strain Selection and Inoculum Preparation: High-yield Aureobasidium pullulans strains are selected and propagated under sterile conditions
- Fermentation: Submerged fermentation in controlled bioreactors using carbohydrate carbon sources, nitrogen sources, minerals, and controlled pH and aeration (48-120 hours)
- Recovery: Biomass removal by centrifugation or filtration to obtain pullulan-containing supernatant
- Purification: Clarification, precipitation, washing, and activated carbon or ion-exchange treatment for high-purity grades
- Drying and Milling: Concentration, drying (spray or vacuum), and milling to desired particle size
- Quality Control and Packaging: Final testing against specifications and moisture-proof packaging
Quality control ensures batch-to-batch consistency and compliance with food/pharmaceutical standards (HACCP, GMP). We can produce pharmaceutical-grade pullulan under cGMP on request.

Frequently Asked Questions
What is pullulan used for?
Pullulan is used as an edible film former, capsule material, binder, stabilizer, and encapsulant in food, pharmaceutical, cosmetic, and packaging industries.
Is pullulan safe for food and pharmaceutical use?
Yes. Pullulan is generally recognized as safe for use in food and pharmaceutical applications when produced under appropriate quality controls. Pharmaceutical-grade pullulan can be manufactured under cGMP.
How is pullulan supplied and stored?
Typically supplied as a dry powder in 25 kg kraft paper bags with an inner PE liner. Store in a cool, dry place away from direct sunlight and moisture. Shelf life is generally 12-36 months.
What grades of pullulan are available?
We offer multiple grades including food-grade, cosmetic-grade, pharmaceutical-grade, and industrial-grade with different viscosities and molecular weights.
Can you supply certificates and test reports?
Yes. Certificates of Analysis (CoA), Material Safety Data Sheets (MSDS), and other documentation are available upon request.
Do you provide samples for evaluation?
Yes. Sample quantities can be provided for testing and formulation trials. Contact sales for sample requests and shipping terms.
What is the MOQ and lead time?
Minimum order quantity and lead time depend on grade and packaging. Typical MOQ is 1 metric ton for standard packaging; smaller trial orders can be arranged. Lead time is usually 2-6 weeks.
Can pullulan be used to make vegan/vegetarian capsules?
Yes. Pullulan offers an excellent plant-based alternative for capsule shells and is used in vegetarian/vegan capsule production.
How does pullulan compare to other film formers like gelatin or HPMC?
Pullulan forms clear, flexible films with superior oxygen barrier properties compared to gelatin and many synthetic polymers. It is tasteless, odorless, vegan, and biodegradable, making it preferable for certain edible film and capsule applications.
