Abstract
PURPOSE: To obtain a pullulan in high yield having a specific molecular weight useful as an plasma expander for preventing and remedying traumatic shocks caused by bleeding, excellent in safety, obtained by hydrolyzing a raw material pullulan partially, followed by fractionation.
CONSTITUTION: A raw material pullulan is partially hydrolyzed with an acid (lactic acid, etc.) or an enzyme (e.g., α-amylase, etc.), and fractionated with a hydrophilic organic solvent (e.g., methanol, etc.), to give a pullulan fraction, which is decolored with active carbon, etc. and desalted. The fraction is filtered by a membrane filter, concentrated of further dried, to give the desired pullulan having a ratio of weight-average molecular weight to number-average molecular weight of ≤1.5 and a weight-average molecular weight of 30,000W90,000.
