Kuma ni iki? Kuma ni inzira yo gukoreshaicyayicyangwa kumisha intoki kugirango amazi arenze mumababi yicyayi ahinduke, yangize ibikorwa bya enzyme, abuze okiside ya enzymatique, ateze imbere reaction ya thermochemiki yibintu bikubiye mumababi yicyayi, kunoza impumuro nuburyohe bwamababi yicyayi, hanyuma bigire imiterere.

Ubushinwa Icyayinigikoresho cyingenzi gikoreshwa mugutunganya icyayi cyambere,Uruganda rwumyecyane cyane ibyuka byicyayi binyuze mubushyuhe, kugirango bigire ubwiza bwubwunvikane budasanzwe hamwe nubwiza buhamye bwicyayi.

Intego yo kumisha icyayi: imwe ni ugukoresha ubushyuhe bwo hejuru kugirango usukure vuba ibikorwa bya enzyme kugirango uhagarike fermentation. Icya kabiri ni uguhumeka amazi kugirango ugabanye amajwi

Icya gatatu, kugirango ukwirakwize uburyohe bwibyatsi, ushishikarize ibintu byimpumuro yicyayi kandi ugumane uburyohe.

Ubushyuhe bwo mu kirere bushyushya byumye kugirango bishyushya umubiri amababi yicyayi, bityo inzira yo gutakaza amazi ava mumababi yicyayi. Ibyiza byo gukoresha aicyayi cyumyenibikorwa byoroshye, gushyushya byinshi kandi nta mpumuro idashimishije.

Mugihe cyo kumisha icyayi, birakenewe kwitondera ibintu bitatu byubushyuhe, ingano yamababi no guhinduka. Ihame ryakurikijwe ni uko ubushyuhe bwabanje kuba hejuru hanyuma bukaba buke, kandi ubwinshi bwamababi bukabanza kuba buke hanyuma bukaba bwinshi. Ubushyuhe bwamababi yicyayi afite amazi menshi agomba kuba menshi kandi amababi agomba kuba make.
