Pullulan

Pullulan is a linear α-glucan polysaccharide produced by aerobic fermentation of the polymorphic fungus Aureobasidium pullulans. The polymer is built from maltotriose units linked by α-1,6 bonds, giving a regular repeating structure unique among commercial gums.

The molecule is highly water-soluble, forms transparent oxygen-barrier films when cast from solution, and lacks the gelling behaviour of most other polysaccharides. It is the leading natural polymer for edible film applications.

We source bulk Pullulan from top China manufacturers for our partners, working with several of them. The manufacturers are in Shandong and Hebei. A smaller requirement can ship in a combined container with other ingredients.

Please send the grade you need, the volume and your destination port, and we will come back with a solution and a price.

Common Markets Grades

Three grades of Pullulan are traded: food, pharmaceutical, and cosmetic.

Food-grade pullulan is the standard for breath strips, edible films, capsules, and confectionery coatings.

Pharmaceutical-grade pullulan meets monograph specifications and is used for hard two-piece capsule shells as a gelatin alternative.

Cosmetic-grade pullulan is produced for facial mask films, hair styling products, and skincare film-formers.

Molecular weight grades range from 100 thousand daltons for low-viscosity applications up to 800 thousand daltons for premium capsule and film use. Spray-dried free-flowing powder and dense granulated formats are both available.

Applications

Edible breath-freshening strips and oral-care films
Hard two-piece capsule shells as a vegan alternative to gelatin and HPMC
Confectionery: panning glaze, sugar coating, and film-forming candy
Bakery: glaze coatings on bread, pastry, and donuts
Cosmetic facial masks and peel-off mask films
Hair styling sprays and natural-positioning hair gels
Pharmaceutical tablet coating and orally disintegrating film technology
Spray-dried flavour and active-ingredient encapsulation
Food packaging films with oxygen-barrier function
Soluble dietary fibre at modest dose

Brands Using Pullulan

Brand names, product names and logos are the property of their owners. They appear here as published evidence that the ingredient is used, taken from the brand's own label or website. Their appearance is not an endorsement, and it does not mean the brand buys from us or from any manufacturer listed on this site.

China Manufacturers of Pullulan

How We Help Source Pullulan

Direct Factory Sourcing
We run the whole process: selecting the manufacturer from the top Chinese food ingredient producers, negotiating the price, verifying quality, and coordinating the logistics. You deal with us instead of with several factories at once.
Original Packaging and Documents from the Manufacturer
The manufacturer sends your Pullulan out of its own factory in the original packing, through to your destination port. The COA, COO, MSDS, TDS and any certifications reach you from the manufacturer as well.
Free Samples and Lead Time
We send 100 to 500 g free for your own laboratory to test and you cover only the courier, usually within 2 to 3 working days. ETD is usually within 7 to 15 days once the order is confirmed, and we check that date against the factory's own manufacturing schedule before we give it to you.
Combined Shipment
We can load Pullulan together with other ingredients such as Carrageenan, Sodium Carboxymethyl Cellulose and Agar Agar into one 20' FCL. If your quantity is small, we can also ship LCL.

Regulatory Status

Pullulan is approved as a food additive in essentially all regulated markets.

Regulation (EC) No 1333/2008 lists it as E1204 in the European Union, restricted to film-coated food supplements and breath-freshening films. The U.S. FDA permits pullulan as GRAS for general food use under multiple GRAS notices.

JECFA has assigned ADI not specified. Japan has approved pullulan since the 1970s as a thickener and film former. Halal, Kosher, vegan, non-GMO, and gluten-free certifications are routinely available.

Manufacturing Process

Pullulan Manufacturing Process

Loading process diagram…

Pullulan is produced by aerobic fermentation of selected strains of Aureobasidium pullulans on a starch hydrolysate or sucrose medium.

Fermentation runs at 24 to 28 °C for four to six days. The fungus secretes pullulan into the broth, where viscosity rises steadily. Yeast-like growth dominates early, with hyphal forms appearing as nutrients deplete.

After fermentation, the broth is heat-killed, then filtered or centrifuged to remove cells and pigment. The clarified broth is decolourised with activated carbon, deionised through ion-exchange resin, and spray-dried.

For premium capsule grades, additional ultrafiltration and molecular-weight fractionation steps standardise the polymer profile.
