Source and Preparation

Pullulan polysaccharide is a kind of special microbial polysaccharide discovered by R. Boer in 1938. It is a kind of extracellular water-soluble mucous polysaccharide similar to glucan and xanthan gum produced by fermentation of sprouted stalk fungus. Black yeast (AureobasidIumpullulans, also called aureobasidium pullulans) were incubated in the medium containing starch hydrolysates (generally cerealose) and inorganic salts (27-30 ℃, 4-7 days), then heated and centrifuged to remove the bacteria, and the filtrate was precipitated with an equal amount of ethanol. It is then dissolved in water and refined.
