Pullulan is non-toxic, non-mutagenic, odorless, tasteless, and edible.
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.
Pullulan is safe, heat-resisting, salt-tolerant, acid and alkali resistant, with good viscosity and heat stability, strong plasticity; it can form film and has good gas isolation and strong moisture permeability. It is also with adhesiveness, adhesion, decomposability. It can improve physical property; maintain moisture, forming property, spinning property and others.
