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 filmformer, 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.
Applications:
Coating
The high binding and film-forming properties of Pullulan make it a valuable ingredient for coating. Not only can Pullulan help produce strong, smooth and highly glossed surfaces but also increase shelf life.
Dressing and Sauces
Due to its 'adhesive property' use of pullulan in sauces improves their 'on product' retention without unduly increasing sauce viscosity. It is acknowledged that it is difficult to retain sauces on the surface of some pre-cooked meat and fish products; but this problem can be overcome by incorporating pullulan into the formulation.
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 heat sensitive materials to be used in these products.
