1. Green tea
2. Oolong tea
3. Black tea
Green tea is produced by inactivating polyfenol oxidation enzyme from fresh tea leaves. This inactivation method can be done by heating and evaporating.
Oolong tea is produced by heating the leaves in the short time after rolling the leaves. Oxidation process stopped when heating process occurs. Oolong tea also called as semi-fermentation tea, and the characteristics are between green tea and black tea.
Black tea is produced by oxidizing the catechin from fresh tea leaves using polyfenol oxidation catalyst. This process also called as fermentation. During fermentation process, the catechin is transformed to be more complex and concentrated molecules.
The main difference among green tea, oolong tea, and black tea is the content of catechin. The highest content of catechin is in green tea, with 16% - 30% of catechin. The lowest content of catechin is in black tea.
