Abstract

Through experiment with treatments of various dosages of radiation and different initial water contents in Puer-tea, it was found that contents of amino acid, tea polyphenols and the oxidation products of polyphenols were increased; oppositely, caffeine and catechins, particularly the compound catechins were decreased; In addition, the radiation treatments had no negative effect on the organoleptic quality of Puer-tea.
