Nkibikoresho fatizo byibanze kurigutunganya icyayi, ubwiza bwamababi mashya bifitanye isano itaziguye nubwiza bwicyayi, aribwo shingiro ryo gushiraho ubwiza bwicyayi.Muburyo bwo gukora icyayi, urukurikirane rwimiti ihinduka mubice bigize imiti yibibabi bishya, kandi imiterere yumubiri wamababi mashya nayo yagize impinduka zikomeye, bityo ikora icyayi gifite ubuziranenge nuburyo bwihariye.Turashobora kuvuga ko ubwiza bwicyayi buterwa ahanini nubwiza bwamababi mashya no gushyira mu gaciro tekinoloji yo gukora icyayi.Ubwiza bwamababi mashya niyo shingiro ryimbere, kandi tekinoroji yo gukora icyayi nuburyo bwo hanze.Kubwibyo, kugirango habeho icyayi cyiza, birakenewe gusobanukirwa ibice bigize imiti bikubiye mumababi mashya nubusabane hagati yubwiza bwamababi mashya nubwiza bwicyayi, kugirango hafatwe ingamba zifatika zo kuyobora no gukora icyayi. tekinike yo gukora icyayi cyiza.

Kugeza ubu, hari ubwoko burenga 700 bwibintu byatandukanijwe kandi bikamenyekana mu cyayi, bishobora kugabanywamo ibice bitatu: amazi, ibinyabuzima, hamwe n’ibinyabuzima.Usibye metabolite eshatu zibanze zisukari, lipide na proteyine, ibinyabuzima kama cyicyayi birimo na metabolite nyinshi zingenzi za kabiri, nka polifenol, alkaloide, theanine, ibintu bya aromatique, pigment, nibindi. Nubwo ibirimo metabolite zimwe na zimwe bitari hejuru , bafite uruhare runini mugushinga ubwiza bwicyayi.
