  • What is species name for tea?

    camellia sinesis

  • What country is the main producers of tea?

    China & India

  • There are two main types of tea, what does it called?

    - var. sinesis (China) -> small leaved

    - var assamica (India) -> large-leaved

  • Why does harvesting leaves is still by manually?

    Because we only want to pick up the young ones

  • State three types of plucking!

    Fine plucking, coarse plucking & imperial plucking

  • What is the difference between Fine plucking, coarse plucking & imperial plucking?

    Fine = bud + 2 leaves

    Imperial = Bud + 1 leaf

    Coarse = Bud + 3 or more leaves

  • Why does plucking tea done in the morning?

    Because the dew in the morning indicates which one has the best quality

  • State three types of tea (based on processing techniques)!

    1. Non fermented tea (catechins : 30-40%)

    2. Semi-fermented tea (catechins : 8-20%)3. Fully fermented tea (catechins : 3-10%)

  • What is the different between Non, semi, & fully fermented tea?

    Non = heated/steam to destroys enzyme that oxidase polyphenols

    Semi = leaves repeatedly rolled and dried to oxidize polyphenols

    Fully = leaves rolled & exposed to air, enzyme oxidize the polyphenols

  • What actually make fermented leaves and non fermented leaves different?

    Fermented = we activate ppo to react with catechins (becomes darker)

    Non fermented = we inactivate ppo so it won't react with catechins

  • Please explain the of white tea processing!

    Withering - drying

  • Please explain the of green tea processing!

    withering - panfrying/steaming/firing - drying/rolling

  • Please explain the of Oolong tea processing!

    withering - shaking/rolling - short fermentation - panfrying - drying

  • Please explain the of Black tea processing!

    withering - rolling/culting - full fermentation - firing (drying)

  • In manufacture of black tea, please describe each of the processes!

    Withering = reduces moisture

    Rolling = enhances the oxidation of ppo and flavonoidsFermentation = conversion of colorless catechins to complex mixture

    Firing = ends fermentation & reduces moisture

  • Ture or false, smaller leaves is more expensive?

    True

  • What is the differences between volatile tea and non volatile tea?

    Volatile = contribute to aroma (catechins)

    Non volatile = does not contribute to aroma (polyphenols)

  • Catechins + ppo produce = ?

    Theaflavins & Thearubigins (uniqueness of black tea)

  • What is the differences between Theaflavins & Thearubigins?

    Theaflavins = bright red pigment; brightness and briskness taste

    Thearubigins = reddish-yellow color

  • What are the benefits of tea?

    - Antioxidant, anticarcinogenic, cell recovery, reduce blood cholesterol

    - Theanine - lowering blood pressure, antitumor

    - Antimicrobial - Prevention and treatment of cardiovascular disorders

  • Types of tea products ?

    Tea bags, RTD tea, Teh wangi, herbal tea, kombucha, white tea..
