He mea nui ngā wai aporo me te pea hei kai nui mō ngā kaihanga inu, tunu taro, me ngā miraka o te ao. Ko te nuinga o ngā kaipuke o te ao e whakawhirinaki ana ki ngā ipu whakamatao (reefer) 20 putu te roa mō ngā haerenga whakawhiti moana 20–45-rā. Ko tētahi take noa mō ngā kawemai ko te huri o ngā wai koura mārama, mārama ki te parauri pouri i te taenga mai—ahakoa ka tukuna i raro i te pāmahana iti tonu. Ko te pumau o te tae, e inehia ana e ngā uara CIELAB L*, a*, b*, he paerewa kounga nui mō ngā kaihanga. E whakamārama ana tēnei tuhinga i ngā take matū o te parauri, ngā āhuatanga mōrearea motuhake ki te reefer, me ngā otinga kua whakamātauhia hei tiaki i te tae i te wā e kawe ana ki tāwāhi.
Ko te tino take o te parauri kore-enzymatic i te wā e tukuna ana ki te waka taupua ko te parauri kore-enzymatic, nā te mea kua whakakorea kētia te polyphenol oxidase (PPO) e te whakahoromata pāmahana teitei aseptic. E toru ngā tauhohenga matū matua e ārahi ana i te pouri:
- Te Tauhohenga Maillard: Ko te take matua. Kei roto i ngā kukū aporo me te pea he nui ngā huka whakaiti (te hukahuka, te fructose) me ngā waikawa amino kore utu. Ahakoa i te 0–4°C, ka āta whakakotahi ēnei matū i roto i ngā wiki hei hanga i ngā melanoidin pouri, ka whakaiti i te kanapa (uara L*) me te whakapiki i te taupū parauri A420. Ka tere ake te parauri o te kukū pea i te 30–50% nā te nui ake o te ihirangi hauota amino.
- Te Waikura Polyphenol: Ko te iti o te hāora toenga i roto i ngā wāhi pane o te pahu aseptic ka puhoi te waikura o ngā polyphenol tūturu (waikawa chlorogenic, catechin), ka hanga he pūmua quinone parauri. Ka tere ake te tauhohenga o ngā katote konganuku (rino, parahi) mai i ngā takai, i ngā taputapu rānei.
- Te Whakangaromanga o te Waikawa Ascorbic: Ka pakaru haere te huaora C tūturu i te rokiroki makariri, ka whakaiti i te tiakitanga ā-pūmua, ā, ka puta te parauri tuarua.
Mā te tuku ipu whakapūmau ka hangaia he āhuatanga ahurei e tere ake ai te ngaronga o te tae, nui atu i te rokiroki matao tūmau:
- Ngā Hurihuri o te Pāmahana: Ko te whakahaere i te tauranga, ngā nekehanga hiko, me ngā huringa pāmahana o te moana ka hua ake ngā huringa ±2–3°C. Ka piki ake ngā tere parauri mā te 32% i raro i te whakamatao koretake, ā, ko ngā pāmahana i runga ake i te 7.2°C (45°F) ka puta te pouri tere i roto i ngā rā 20 noa iho.
- Ngā Wā Roa mō te Haerenga: Ka whakanuia ake te parauri kore-whākōkī e pā ana ki te wā e ngā haerenga 25–40-rā. Ka piki ake te taupū parauri o te pea concentrate mā te neke atu i te 0.3 wae i muri i ngā rā 30 i te 4°C.
- Te Whakapuakitanga o te Mārama: Mā ngā tirotiro a te tari tāke ka whakaatuhia ngā kukū matū ki te mārama UV me te mārama e kitea ana, ka whakaitihia ngā tae me ngā uara L*.
- Ngā turuturu e pā ana ki te wiri: Ka puta he turuturu moroiti i roto i ngā hiri putea ātete i te aueue o te moana, ka taea ai te uru o te hāora me te pōuriuri ā-rohe.
He rerekē rawa te pumau o te tae i waenga i ngā mea e whakaranua ana ki te aporo me te pea:
| Rārangi | Pūmua Apple Mārama | Wai Pēra Kukū |
|---|---|---|
| Tae Tūāpapa | Kōwhai kakau mā | He koura māwhero mārama |
| Tere o te Parai | Waenga | 30–50% tere ake |
| Hua o te Whakamahana Reefer 30-Rā | He paku tae amipere | Te nekehanga kōwhai-parauri mārama |
Hei kaihokohoko Hainamana ngaio, ka whakatinanahia e mātou he pūnaha whakahaere tukanga-katoa hei whakaū i te tae mō ngā tukunga waka whakatō 20 putu:
- Te Kōwhiringa Rauemi Mata: Ka whiriwhiria e mātou ngā momo hua he iti te polyphenol, he iti te waikawa amino, ā, ka whakakorea ngā hua kāore i te pakari rawa, kāore hoki i te pakari rawa hei whakaiti i te parauri o ngā hua.
- Te Kukū Korehau i te Pāmahana Iti: Mā te whakamahi i te mimiti i raro i te 60°C (kaua ki ngā tikanga wera nui tuku iho) ka whakaitihia ngā tauhohenga Maillard tuatahi, ā, ka tiakina te tae mārama tūturu.
- Tākai Ārai Matepukupuku Kī tonu i te Hauota: Ka whakakīia katoatia ngā ipu kia kore ai e puta te āputa, ā, ka nekehia te toenga o te hāora ki te hauota kai-kai (O₂ ≤0.5%). Ka ārai ngā ipu maitai kore waikura kai-kai i te poke o te katote konganuku.
- Ngā Paerewa Tino Pai mō te Whakahaere i ngā Waka Reefer: Ka whakahau mātou kia mau tonu te pāmahana tuku kaipuke i waenganui i te 0–2°C (kaua e neke ake i te 5°C), ka whakaitihia te tuwhera o ngā tatau ipu i te wā e tirotirohia ana e ngā tikanga, ā, ka karohia hoki te pānga o te rā ki te taha maui.
- Te Hanganga Ārai Mate Taiao: Ka tāpirihia he iti noa o te waikawa citric tūturu me te huaora C mai i te hua hei whakatika i te pH me te aukati i te waikura, kia rite ki ngā ture a te FDA me te EU—kāore he mea tiaki hangai mō ngā ota rauropi.
Ngā Pātai Auau mō ngā Kaihoko o te Ao
- He mōrearea te parauri pouri? He panoni tirohanga noa iho te parauri ngawari, kāore he mōrearea haumaru; ka mau tonu te reka me te kakara karepe maroke. Ko te parauri pouri nui ka puta mai i te takai pakaru, i te pāmahana teitei rānei, ā, ka āraihia e ā mātou mana whakahaere.
- Ka taea e ngā waka tio (-18°C) te aukati i te parauri? Ahakoa ka aukati te tio i te parauri, ka pakaru te hanganga koloidal o ngā kukū mārama, ka puta he kapua me te paru pumau. Ka tūtohu noa mātou kia tukuna he hukapapa mō te kukū aporo kapua.
- Kia pēhea te roa e mau ai te tae? Mā te whakamahi i tā mātou takai hauota, ka mau tonu te pūmua aporo mārama mō ngā rā 35, ā, ka mau tonu te pūmua pea mō ngā rā 28 i roto i ngā ipu whakaruruhau 0–2°C.
Hei whakamutunga, ko te parauri o te wai aporo me te pea i te wā e tukuna ana ki roto i te pouaka whakamātao ka puta mai i ngā tauhohenga kore-enzymatic, ā, ka kino ake i ngā huringa pāmahana, te roa o te kawe, te māramatanga, me te hāora. Ko ā mātou otinga whakauru—mai i te whiriwhiri rauemi mata ki te whakahaere pai o te pouaka whakamātao—ka āta whakaroa i te rerekētanga o te tae, ā, ka whakarite kia rite te kounga o te tae i te taenga mai. Mō ngā pouaka whakamātao pumau, kua whakamanahia te tae, me ngā utu tuku pouaka whakamātao 20 putu te roa, whakapā atu ki tā mātou tīma hokohoko mō ngā whakaritenga katoa me ngā pūrongo taiwhanga.
