Masamba a tiyi nthawi zambiri amafufuzidwa mothandizidwa ndi aMakina Opangira Tiyi, koma tiyi wakuda ndi wa exogenous microbial nayonso mphamvu, kuwonjezera pa enzymatic anachita masamba okha, kunja tizilombo kumathandizanso nayo nayonso mphamvu.Mu Chingerezi, njira yopanga tiyi wakuda imatchedwa "oxidation", mwachitsanzo, oxidization, pamene tiyi wakuda ndi "fermentation" weniweni.

Fermentation ndi njira yapadera yopangira tiyi wakuda.Mu mdima tiyi pambuyoMakina Odzaza Tiyi kupotoza, ndondomeko ya mulu kwenikweni ndi njira nayonso mphamvu, tiyi wakuda mulu wothina, owazidwa ndi madzi, tiyi wakuda muMakina Opangira Mafuta a Tiyi Wakudapambuyo mlingo wina wa chinyezi ndi kutentha kulamulira, pakati pa mulu pamene kutentha kufika madigiri 70 Celsius, kutembenukira mulu kuti kutentha yunifolomu, kuti mobwerezabwereza nthawi zambiri.Limbikitsani ntchito ya ma enzymes mkati mwa tiyi, kuphatikiza ndi zochitika zazing'ono, kulimbikitsa kusintha kwa tiyi.

Chilichonse chikakhala bwino, kagayidwe kake kake, kuphatikiza ndi ma enzymes akunja omwe amatulutsa, amatha kuphwanya tiyi ambiri a polyphenols, ma polysaccharides, protopectin, terpenes, mapuloteni, ndi zinthu zina mu tiyi, zomwe zimapangitsa kuti tiyi ikhale yakuda. fungo lapadera la tiyi ndi kukoma kwake.

Ndipo kuwonjezera pa kuwira kwa Wadding, tiyi wakuda ali ndi fermentation yapadera yachiwiri, yomwe imadziwikanso kuti post-fermentation, yomwe ndi pulogalamu yeniyeni yakupha ya tiyi wakuda.

Njira yomaliza ya tiyi wakuda ndikuti masamba a tiyi amaponderezedwa mu njerwa kapena makeke ndiMakina osindikizira a Keke ya Tiyi kupita mumsewu wautali wa tiyi.Pamsewu wautali uwu, masamba a tiyi nthawi zambiri amasungidwa m'malo opumira mpweya, chinyezi china komanso kutentha, ndipo pambuyo pa zaka zingapo zakuwira kwachilengedwe, njirayi imatchedwa "secondary fermentation", yomwe imadziwikanso kuti post-fermentation.
