Tikamakamba za tiyi, nthawi zambiri timakamba za kuwira kwathunthu, kuwira pang'ono, ndi kuwira pang'ono. Thefermentation makinandi makina omwe amagwiritsidwa ntchito kwambiri pokonza tiyi. Tiyeni tiphunzire za nayonso mphamvu ya tiyi.

Fermentation ya tiyi - biological oxidation

Tiyi yaku China imagawidwa m'magulu asanu ndi limodzi a tiyi molingana ndi magawo osiyanasiyana a nayonso mphamvu komanso njira zopangira zambiri. Mu tiyi, tsamba lobiriwira lomwelo limasinthidwa kukhala tiyi wobiriwira, tiyi wakuda, tiyi wa oolong, ndi zina zambiri. Izi zimafanana ndi zochitika zingapo za enzymatic, ndipo mwina ziyenera kutchedwa biological oxidation. Mothandizidwa ndi biological oxidation ya tiyi cell khoma kuwonongeka mumakina owotchera tiyi, ma oxidase omwe amapezeka mu khoma la cell amalimbikitsa njira zingapo za okosijeni za katekisimu.

M'maselo a tiyi, makatekini amakhala mu selo madzimadzi, pamene oxidase makamaka amakhala mu selo khoma, osati makamaka tizilombo ting'onoting'ono, kotero khoma selo ayenera kuonongeka. Izi zikufotokozera chifukwa chake tiyi wothira amafunikira kugudubuza ndi atiyi tsamba wodzigudubuza. Malinga ndi kuchuluka kwa makutidwe ndi okosijeni a ma polyphenols, amatha kugawidwa kukhala fermentation, theka-fermentation ndi fermentation kuwala. Mu tiyi wakuda, mlingo wa okosijeni wa polyphenols ndi wokwera kwambiri, womwe umatchedwa fermentation yonse; mu tiyi oolong, mlingo wa makutidwe ndi okosijeni wa polyphenols ndi pafupifupi theka, amene amatchedwa theka nayonso mphamvu.

Zomwe zili pamwambazi ndi tanthauzo lenileni la nayonso mphamvu yomwe nthawi zambiri imanenedwa mu tiyi yaku China. Komabe, chifukwa cha mitundu yosiyanasiyana ya tiyi ku China, njira zopangira zopangira zambiri komanso njira zokonzekera, komanso matanthauzidwe osiyanasiyana amtundu, anthu amakonda kugwiritsa ntchito.makina opangira mafuta a tiyi amagetsikuchita nayonso mphamvu yolamulidwa. Pakupanga ndi kupangika kwabwino kwa masamba ena a tiyi, kuwonjezera pa kuwira komwe tatchula pamwambapa m'lingaliro la oxidation yachilengedwe komanso momwe ma enzymatic reaction, ma microorganisms nawonso amakhudzidwa ndi maulalo ena.
