Pullulan polysaccharide

Products Name :Pullulan polysaccharide

Category : Food Additive

Product description :
Pullulan, an extracellular water-soluble microbial polysaccharide produced by strains of Aureobasidium pullulans is a linear -D-glucan made mainly of maltotriose repeating units interconnected via -(16)linkages. It is a kind of characteristic polysaccharide ,which was first found by R.Bauer in 1938. The molecular weight of pullulan is from 4.8104 to 2.2106 dol. The average molecular weight of Commodity pullulan is 2105consisting approximately of 480 maltotrioses.

Application :
A number of potential applications have been reported for pullulan as a result of its good film-forming properties; pullulan can form thin film which is transparent, oil resistant and impermeable to oxygen. Pullulan may be used as a coating and packaging material, as a sizing agent for paper, in plywood manufacturing, and in dielectric condensors, as a starch replacer in low-calorie food formulations, in cosmetic emulsions, and in other industrial and medicinal applications. Other potential applications include use as an adhesive binder, thickener and encapsulating agent. In conclusion, this polysaccharide is of economic importance with increased applications to the food, pharmaceutical and chemical industries.
