Introduction
Pullulan is natural water-soluble polysaccharide, produced from starch by fermentation. It is a linear, neutral glucan consisting mainly of maltotriose units linked through α-1, 6 - glucosidic bonds. Pullulan is an extremely versatile ingredient providing a technology platform for product innovation. It is an excellent film-former, producing a film which is heat sealable with good oxygen barrier properties and which can also be printed. It can be used widely as thickening or extending agents and adhesives or encapsulating agents, in food and pharmaceutical industry.
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 and thus higher intakes than the current application.
Molecular formula
(C6H10O5)x
Properties
Pullulan is non-toxic, non-mutagenic, odorless, tasteless, and edible. Dry pullulan powders are white and non-hygroscopic and dissolve readily in hot or cold water. Pullulan solutions are of relatively low viscosity. The viscosity of pullulan solutions is stable to heating, changes in pH, and most metal ions, including sodium chloride.
