The thesis focused on extraction, analysis and application of tea polyphenols(TP)
as follows:
Systemic study on the extraction of tea polyphenols was carried out. Firstly, the influence caused by some factors on TP leaching rate was studied. The orthogonal experiment showed that the optimum condition of leaching TP was- 60% ethanol as solvent, under 70℃, the ratio of tea and solvent is 1:20, leaching 2 times and 20min
every time. Under the conditions ,the maximum...
