Product DescriptionPullulan Introduction

Pullulan is natural water-soluble polysaccharide, fermented by Auveobasidium Pullulans. It consists mainly of maltotriose units linked through α-1, 6 - glucosidic bonds. The average molecular weight is 2×105 Da. Pullulan can be developed into various products. It is an excellent film-former, producing a film which is heat sealable with good oxygen barrier properties. It can be used widely in both the pharmaceutical and food industries, such as encapsulating agents, adhesives, thickening, and extending agent. Pullulan has been used as a food ingredient for over 20 years in Japan. It has Generally Regarded As Safe (GRAS) status in the US for a much wider range of applications.

Molecular formula: (C6H10O5)x

Pullulan Properties

1. Pullulan is non-toxic, non-mutagenic, odorless, tasteless, and edible.

2. Dry pullulan powders are white and non-hygroscopic and dissolve readily in hot or cold water.

3. Pullulan solutions are of relatively low viscosity.

4. The viscosity of pullulan solutions is stable to heating, changes in pH, and most metal ions, including sodium chloride.

3. Binder agent for sugar coating

Pullulan is an excellent binder for sugar coating in spite of its low viscosity. It provides a smooth coating that is resistant to cracking.

4. Clazing agent for processed sea food

Pullulan is a good glazing agent and can be used to create a transparent glaze. It also possesses good workability due to its low viscosity.

5. Texture improvement (soft candy)

Soft candy formulated with pullulan adheres less to teeth. The candy is soft but stable at the same time.

6. Binding agent

The high adhesiveness and low viscosity of pullulan make it excellent as a binding agent in such foods as cereal bars, and as a granulation aid.

7. Film forming property

Pullulan has film-forming properties. It forms a thin film that is transparent, oil resistant and impermeable to oxygen. Pullulan film can also be printed on, which is useful for many kinds of foods.
