Theme - Tea oxidation

„Unlike green tea produced in china which is dried with hot air after the pan-frying stage to completely kill enzyme activity, leaves used in the production of pu-erh are only pan-fried and thus a small amount of enyzmes are left which contribute a minor amount of oxidation to the leaves during sun-drying“

„Although green tea does not raise the metabolic rate enough to produce immediate weight loss, a green tea extract containing polyphenols and caffeine has been shown to induce thermogenesis and stimulate fat oxidation, boosting the metabolic rate 4% without increasing the heart rate.“

„The leaves are then dry pan-fried using a large wok in a process called "kill green" (殺青; pinyin: shā qīng), which arrests most enzyme activity in the leaf and prevents full oxidation. After pan-frying, the leaves are rolled, rubbed, and shaped into strands through several steps to lightly bruise the tea and then left to dry in the sun.“
