Abstract
The optimal extracting conditions of tea polysaccharide in green tea were studied in this paper.The results showed that the first affecting factor of the extracted rate was temperature,the second was time,the third was extraction times,and the last was ratio of tea to water.The optimal parameters were as follows:tea-water ratio was 1∶10,extraction temperature was 85 ℃ extraction time was 90 minutes,extraction times were 2 times.
