Hariho ubwoko butanu bwaimashini itunganya icyayi: gushyushya, amavuta ashyushye, gukaranga, gukama no gukaranga izuba.Icyatsi kibisi kigabanyijemo gushyushya no gushyuha.Nyuma yo gukama, igomba no gukama, igabanijwemo uburyo butatu: gukaranga, gukaranga no gukama izuba.

Umusaruro wicyayi kibisi urashobora kubivuga muri make nkicyayigutora, gutunganya, kuzunguruka no gukama.Muri byo, gukiza bivuga gukoresha ubushyuhe bwo hejuru kugira ngo wangize vuba ibikorwa bya enzyme mu mababi y’icyayi, ukirinda okiside ya enzymatique ya polifenol, bigatuma amababi mashya atakaza igice cy’amazi, kandi byoroshye icyayi gukora nyuma.Icyatsi kibisi nacyo shingiro ryubwiza bwicyayi kibisi.

Muri rusange, gukosora bifite imirimo itatu:

1. Gusenya ibikorwa bya enzyme no kwirinda okiside ya polifenol;

2. Gukwirakwiza ibyatsi bibisi no kongera impumuro yicyayi;

3. Fira amababi yicyayi yoroshye kugirango byorohereze umusaruro.

Ubushyuhe bwo hejuruimashini itunganya icyayiguhumeka amazi mumababi mashya.Amababi amaze kubura igice, imiterere yamababi iba yoroshye kandi ubukana bwiyongera, byoroshye kuzunguruka no gushushanya nyuma.Inzira yo kudakora enzyme irashobora kugabanwa muburyo bubiri: gushyushya hamwe na parike ishyushye.Uburyo bwo kumisha nyuma yo gukira burashobora kugabanywa muburyo butatu: gukaranga, gukama izuba no gukama izuba.Kubwibyo, ukurikije uburyo butandukanye bwo gutunganya no gukama, icyayi kibisi gishobora kugabanywamo ibyiciro bine: icyayi kibisi gikaranze, icyayi kibisi gikaranze, icyayi kibisi cyumishijwe nizuba hamwe nicyayi kibisi.

1.Icyayi kibisi gikaranze: bivuga uburyo bwicyayi bukaranze bushingiye kumababi yicyayi akaranze muri aimashini yicyayi(cyangwa ikaranze neza), ikora impumuro nziza kandi igarura ubuyanja hamwe nuburyohe bworoshye kandi bugarura ubuyanja.Muri byo, Longjing nicyayi kizwi cyane gikaranze icyayi kibisi.

2. Icyayi kibisi gikaranze: bivuga uburyo bwamababi yicyayi yumye cyane (cyangwa yumye rwose) hamwe naicyayikurema impumuro nziza nuburyohe buryoshye.Impumuro yicyayi kibisi ikaranze ntabwo ikomeye nkicyayi kibisi gikaranze.

3. Icyayi kibisi cyumishijwe n'izuba: bivuga uburyo bw'icyayi kibisi cyumye cyumye cyane cyane icyatsi cyumishijwe n'izuba (cyangwa icyatsi cyose cyumishijwe n'izuba), gifite impumuro nziza, uburyohe bukomeye hamwe nicyatsi kibisi cyumye.Icyayi kibisi cyumishijwe n'izuba nicyiza cyiza mumoko manini ya Yunnan kandi yitwa "Dianqing".

4. Icyayi kibisi kibisi: Theimashini itunganya icyayiikoresha amavuta kugirango isenye ibikorwa bya enzyme mumababi mashya, ikora "icyatsi kibisi" kiranga icyayi cyumye: ibara ryicyatsi kibisi, ibara ryisupu yicyayi kibisi, hamwe nibara ryamababi yicyatsi kibisi, hamwe nimpumuro nziza kandi uburyohe bushya.
