In terms of processing technology, black tea belongs to fully fermented tea, which is refined from the bud leaves of tea trees through typical processes such as withering, rolling, fermentation and drying. Green tea, on the other hand, is a kind of non-fermented tea, which is made of new leaves of tea tree, without fermentation, by typical processes such as enzyme fixation, kneading and drying.

After fermentation, the chemical reaction of tea polyphenols in black tea was reduced by more than 90%, and new components such as theaflavins and thearubigins were produced. Green tea has not been fermented, so it retains many original components of tea, including tea polyphenols, catechins, chlorophyll,
