Treatment under mild condition with solvent of lower polarity was in favor of keeping the molecular structure and properties such as water-solubility, gelatination, etc. Acetyl groups were partially eliminated when purified by Pb2 method, leading to increased crystallinity and glass temperature, which resulted in losts of water-solubility and gelatinability.
