PULLULAN--Polysaccharide

Introduction

Pullulan is natural water-soluble polysaccharide, fermented by starch syrup with a selected strain of Aureobasidium pullulans. It consists mainly of maltotriose units linked through α-1, 6 - glucosidic bonds. 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.

Chemical formula: (C18H30O15)n

CAS No.:9057-02-7

Pullulan was approved as a food ingredient in Japan in 1976, was approved by FDA and recorded in GRAS(GRAS Notice No.GRN99) in 2002., EU,Austria,Canada approved Pullulan as a food additive already.

 

Physical Properties

Solubility

Pullulan is readily soluble in water, practically insoluble in ethanol (99.5%).

Lubricity and adherence

Pullulan solution is a Newtonian fluid, with excellent lubricity and adherence in spite of low viscosity. This makes pullulan highly useful for foods requiring thickening.

Stability

Pullulan solution does not turn into gel, having low viscosity compared with the other polysaccharides. The viscosity of pullulan is stable, being resistant to the addition of metal salts. Prolonged heating at pH3 leads to decrease in viscosity, which is indicative of a hydrolytic depolymerization.

Digestibility

Pullulan is a resistant polysaccharide equal to cellulose and pectin.
