Different types of tea
Tea tree. Scientific name: Camellia sinensis. The young shoots and stems are processed and transformed into various teas. Which can be divided according to the production process as follows:
- Black Tea is a tea that has been completely fermented. (Completely-fermented tea) The tea leaves are dried to allow the polyphenol oxidase enzyme to fully catalyze. The polyphenols are completely oxidized to form compounds of Theaflavins and Thearubigins, resulting in reddish-brown black tea.
- Oolong tea is a tea that has been partially fermented. (Semi-fermented tea) before stopping the reaction of the enzyme by heating The production process will be dried with the sun for about 20-40 minutes. After the sun is dry, the tea leaves will be dried in the shade again and shaking to stimulate the tea to wake up. This desiccation is a fermentation process, which causes polyphenol oxidase to accelerate the oxidation and polymerization of polyphenols, resulting in the dimers and complexes of polyphenols. Oolong tea has a yellowish-green color. And greenish brown
- Green tea is a tea that has not been fermented. (Non-fermented tea) The production process begins with the cessation of the enzyme Polyphenol oxidase in fresh tea leaves by steaming or steaming on a pan firing to prevent the polyphenol oxidase enzyme. Can accelerate the oxidation and polymerization reaction of the tea polyphenols After that, massage (rolling) to break the cells and massage to make the tea leaves to roll. Then dried The color of this type of tea is green to yellowish-green.
- Pu’er tea is a tea that has undergone some fermentation processes. (Semi-fermented tea), most popular as a lump and then cured for many years, the longer the longer curing, the more expensive.
- White tea is a tea produced from shoots or young stalks. Not through fermentation processes at all Then dried The resulting tea is pale yellow.
- There is another type of tea called tea but not tea, herbal tea. Is to bring herbs to drink for drinking Without any tea tree ingredients (Camellia sinensis).
