Hononga Moni

He mārama ngā herenga o ngā miro API tuku iho i roto i ngā āhuatanga mahi uaua: he pai te hiri o ngā miro porowhita API engari he 60%–80% noa iho te kaha kume o te tinana-paipa, ā, kāore e pai te mahi poka hohonu; he nui te kaha kume o ngā miro poutū API engari he ngoikore te hiri, ā, kāore e taea te urutau ki ngā poka hau pēhanga teitei. I taua wā, ko te hinu miro paerewa ka mahi noa i raro i te 95℃, ka aukati i te tono poka pāmahana teitei.
Ko te Hononga Kounga (miro kounga motuhake) he hanganga miro kore-API kua whakapai ake me te mahi whānui
ngā painga:

1. He tino pai te mahi hiri whakarewa rapa, he rite te kaha hiri hononga ki te rohe pēhanga hua o te paipa-tinana;

2. Ka eke te kaha o te hononga ki te kaha o te tinana-paipa, ka nui ake rānei, ā, ka ea katoa ngā raruraru paheke o te miro;

3. Ko te rauemi me te maimoatanga mata kua arotauhia kia kore ai e pakaru te piri o te miro;

4. Mā te hoahoa hanganga whaitake ka pai ake te tohatoha ahotea hononga me te ātete ki te waikura ahotea;

5. Mā te hanganga pakihiwi kua arotauhia ka māmā ake te mahi miro i te papaanga.
