Description
Pullulan is a linear homopolysaccharide of glucose, which is produced as a water-soluble, extracellular polysaccharide by certain strains of the polymorphic fungus Aureobasidium Pullulans (De Bary) Arnaud.
Pullulan has adhesive properties and can be used to form fibers, compression moldings, and strong, oxygen-impermeable films.
In pharmaceutical industry, Pullulan can be used as a denture adhesive, in the sugar coated pharmaceutical compositions to prevent brownish color change of the composition.
Pullulan can also be used in cosmetics, lotions, and shampoos.

Pullulan is a polysaccharide polymer consisting of maltotriose units, also known as α-1,4- ;α-1,6-glucan'.
Three glucose units in maltotriose are connected by an α-1,4 glycosidic bond, whereas consecutive maltotriose units are connected to each other by an α-1,6 glycosidic bond.

Function:
Pullulan can be used as either an innovative or decorative film or used in granule form for
Tabletting: Pullulan is an excellent tabletting excipient.
Pan coating: Pullulan with its excellent adhesive properties and extremely low viscosity is ideally suited for pan-coating chewing gum, chocolate and candies.
Agglomeration: Pullulan has about double the adhesive strength of food starch.
This property combined with Pullulan's lack of flavor enables Pullulan to be used effectively in typical agglomeration processes.
Sauces and dressings: Due to its 'adhesive properties' use of granular pullulan in sauces improves their 'on product' retention without unduly increasing sauce viscosity.
Innovative soft candy: Incorporation of 2-3% Pullulan, enables innovative soft chewy candies to be made by a cold extrusion process without resorting to conventional boiling.
This enables heart sensitive materials to be used in these products.
Coatings: Pullulan solutions which are odorless and flavorless can be used as a coating for a wide range of food products to improve appearance, reduce blemishes and increase shelf life.
Capsules: Pullulan can be formed into capsules for use with pharmaceutical and nutraceutical products.
Pullulan's non-animal origin ensures there are no safely concerns with consumers and Pullulan is suitability for all consumers groups.

Pullulan has been used in a study to assess bone tissue engineering.
Pullulan has also been used in a study that investigated anti-fog applications.
Application Area:
Uridine 5-Mophosphate Disodium are produced through the hydrolytic reaction from Ribonucleic acid(RNA) as raw material by enzymatic catalysis to form four kinds of nucleotides 5- 'AMP (adenosine-5'-monophosphate), 5'-GMP•2Na(guanosine-5'-monophosphate, disodium salt), 5'-CMP(cytidine-5'-monophosphate)-, 5'-UMP•2Na (uridine- 5'-monophosphate,Disodium salt) .By the chromatographic isolation, four kinds of separated 5'-nucleotide products with high purity can be obtained.
These products can be widely applied in medicine, reagent, fine chemical industry, and additive of food fields etc.

Characteristics of Pullulan polysaccharide:
1.Non-toxic safety: According to the results of the acute, subacute and chronic toxicity tests of Lullulan polysaccharide, even if the dosage of Lullulan polysaccharide reaches the LD50(half lethal dose) limit of 15g/kg, Pullulan will not cause any biological toxicity and abnormal state, so Pullulan is used in food and medicine Pullulan's safe for the chemical industry and Pullulan is a prebiotic.
2. Solubility: Pullulan polysaccharide can be dissolved in water, dissolution rate than carboxymethyl cellulose, sodium alginate, polypropylene alcohol, polyvinyl alcohol more than two times faster, the solution is neutral, no ionization, no gelation, no crystallization.
Different water temperatures have little effect on the dissolution properties of Pullulan, so the dissolution temperature range of pullulan is wide (0~100ºC).
3.Stability: The molecules of Pullulan have linear structure, so compared with other polysaccharides, the aqueous solution of Pullulan is less viscous and does not form colloid.
Pullulan is a neutral solution with strong adhesion.
Pullulan contains almost no reducing group and only produces weak intermolecular forces with other molecules.
When the pH value is below 2.5, if heated for a long time, Pullulan will partially decompose like other polysaccharides, resulting in a decrease in the viscosity of the solution.
4. Acid and alkaline resistance: Pullulan is acid-resistant but not alkali-resistant, and Pullulan's pH tolerance ranges from 2.5 to 9.5.
5. Stickiness: Pullulan polysaccharide has strong viscosity.
This characteristic is used in a wide range of pharmaceutical products, such as tablet adhesives and film adhesives for wound healing sites.
6. Membrane forming: Pullulan has excellent membrane forming Pullulan membrane is 10 times higher than gelatin, 10 times higher than cellophane, 30 times higher than PVDC, It is 80 times higher than LDPE(low density polyethylene) and 200 times higher than HPMC.
Pure Pullulan polysaccharide film can isolate air and water molecules, etc.
When pullulan polysaccharide is mixed with other substances, Pullulan can adjust the air insulation after forming the film.
In addition, the Pullulan capsule has a high tensile strength.
7.Protective agent.: After forming the membrane, pullulan polysaccharide can well protect the contents of Pullulan's coating from oxidation and volatilization, prolong the action time of the active components, and the membrane also has a certain ability of ultraviolet resistance.
After forming pullulan film, under the dry condition of the surface, Pullulan also can prevent bacteria and other infiltration.
This characteristic of Pullulan is widely used in medicinal capsule shell, wettable medical bandage, animal protection, cosmetics, food film protection and other fields.
8.Decompose: Pullulan at over 250 degrees Celsius.
In the natural environment, the right conditions (temperature, moisture, air), can be degraded by bacteria.
Belongs to the green environmental protection natural material.
