Amaqabunga etiye avame ukuvutshelwa ngosizo lwe-aUmshini Wokuvubela Itiye, kodwa itiye elimnyama lingele-exogenous microbial fermentation, ngaphezu kokusabela kwe-enzymatic kwamaqabunga ngokwawo, ama-microorganisms angaphandle nawo asiza ukuvutshelwa kwawo. NgesiNgisi, inqubo yokukhiqiza itiye elimnyama ichazwa ngokuthi "i-oxidation", okungukuthi i-oxidization, kanti itiye elimnyama liwukuvutshelwa kwangempela "ukuvutshelwa".

Ukuvutshelwa kuyinqubo eyingqayizivele yokukhiqiza itiye elimnyama. Etiyeni elimnyama emva kwalokhoTea Rolling Machine ukusonteka, inqubo yenqwaba empeleni iyinqubo yokuvutshelwa, inqwaba yetiye elimnyama inqwabelanisa, ifafazwe ngamanzi, itiye elimnyamaUmshini Wokucubungula Ukuvutshelwa Kwetiye Elimnyamangemva kwezinga elithile lomswakama nokulawula ukushisa, phakathi kwenqwaba lapho izinga lokushisa lifinyelela ku-70 degrees Celsius, ukuguqula inqwaba ukwenza iyunifomu yokushisa, ukuze kuphindwe izikhathi eziningi. Khuthaza indima yama-enzyme ngaphakathi kwetiye, ehambisana nomsebenzi wamagciwane, ukukhuthaza ukuguqulwa kwetiye.

Lapho konke kuhamba kahle, i-metabolism yamagciwane uqobo, kuhlanganiswe nama-enzyme aphuma ngaphandle, kungaphula ama-polyphenols etiye amaningi, ama-polysaccharides, i-protopectin, i-terpenes, amaprotheni nezinye izinto etiyeni, okuholela ekwakhekeni kobumnyama. iphunga eliyingqayizivele letiye kanye nokunambitheka.

Futhi ngaphezu kokuvutshelwa kwe-Wadding, itiye elimnyama linokuvutshelwa kwesibili okuyingqayizivele, okwaziwa nangokuthi i-post-fermentation, okuwuhlelo lokusebenza lwangempela lombulali wetiye elimnyama.

Inqubo yokugcina yetiye elimnyama ukuthi amaqabunga etiye acindezelwa ezitini noma amakhekhe yi-Umshini Wokucindezela Ikhekhe Letiye ukuhamba emgwaqeni omude wetiye. Kulo mgwaqo omude, amaqabunga etiye avamise ukugcinwa endaweni engenawo umoya, enomswakama othile kanye nezinga lokushisa, bese kuthi ngemva kweminyaka embalwa yokuvutshelwa kwemvelo, le nqubo ibizwa ngokuthi ukuvutshelwa kwesibili, okubuye kwaziwe ngokuthi i-post-fermentation.
