| Abstract: | Pullulan purified by means of savage and indentified by thin plate chromatography contains 0.5% protein. The viscometry indicated that the molecular weight of pullulan is 49 000. Green tea coated with pullulan was kept under certain conditions, and the percentage of its polyphenol tea was determined continously. The result reveals that pullulan provides protection for polyphenol tea efficiently. |
