【Abstract】 The leaves of raw brick tea contain more fluoride usually. Excessive intake of fluoride could induce fluorosis for the people who have a habit of drinking the brick tea. In order to control this type of fluorosis, a new method of defluorination from leaves of raw brick tea was studied. Results showed that fluoride content in raw tea decreased clearly and tea color and polyphenol content of tea haven’t change obviously after treatment by the new method. Perhaps it may give a new way for controlling the high- fluoride in brick tea.更多还原
