Mō ngā kaiwhaiwhai tunu kai kāinga, ko ngā oumu me ngā mīhini whakaranu tū ngā "taputapu matua" e mōhiotia whānuitia ana, engari he iti noa iho te hunga e mōhio ana—ko te pouaka whakamātao te "toa tautoko tunu kai" huna. Mai i te whakahaere i te whakangawari pata me te whakamatao i te paraoa pokepoke hei whakapūkara ki te tiaki i te kirīmi whiu me te penapena i ngā keke kua oti, ko ia taahiraa e whakawhirinaki ana ki te tautoko o te pouaka whakamātao. Mā te whiriwhiri i te pouaka whakamātao tika e hāngai ana ki ngā hiahia tunu ka taea te whakaneke rua i tō angitu, ā, ka taea hoki te whakaora i te nui o te raruraru.
1. Te Whakahaere Pāmahana Tika + Te Whakaiti i ngā Hurihuri Pāmahana: Ārai i ngā Āwangawanga Tunu Kai
Kia pēhea te aro o te tunu ki te pāmahana? Whakaarohia tēnei tauira māmā: Me noho te kirīmi whiu ki te wāhi matao. Mena he tino teitei rawa te pāmahana o te pouaka whakamātao, ka rewa wawe pea te kirīmi, ā, kāore e taea te whakatutuki i ngā tihi pumau. Waihoki, me whakamatao te pata mō ngā pihikete ki tētahi mārō motuhake. Mā te rerekētanga pāmahana o te 1-2°C noa iho ka ngawari rawa te pata, ka ngaro te āhua o ngā pihikete, ka piri rānei. Heoi, ko te whakahaere tika i te pāmahana te paearu matua mō ngā kaihanga keke kāinga ina whiriwhiri ana i tētahi pouaka whakamātao.
Me pupuri e te pouaka whakamātao pai rawa atu he pāmahana pumau i waenganui i te 3-5°C me te pāmahana o te pouaka tio i raro iho i te -18°C. Kaua e neke ake i te 1°C ngā rerekētanga pāmahana puta noa i ngā rohe rerekē i roto i te waeine. Whakaritea ngā tauira e whakaatu ana i te "whakahaere pāmahana rorohiko," e tuku ana i ngā whakarerekētanga tika ake i ngā pūnaha mīhini, ā, e whakarato ana i ngā whakaaturanga pāmahana wā-tūturu hei aroturuki watea i te wā tunu. Hei tāpiri, ko ētahi pouaka whakamātao papai he "hangarau hongere rere hau," e whakarite ana i te rere o te hau matao ōrite puta noa i te waeine. Mā tēnei ka ārai i ngā kai mai i te tio totoka tata ki ngā pūaha hau, i te pirau rānei nā te wera nui ina rongoatia tawhiti atu i a rātou, he mea tino pai mō te penapena i ngā kai tunu e hiahia ana ki ngā pāmahana pumau.
2. Wāhanga Pāmahana Rerekē Motuhake mō ngā Hiahia Tunu Kanorau
I roto i te tunu kai kāinga, he rerekē ngā pāmahana e hiahiatia ana mō ngā kai me ngā tukanga rerekē: me 1-4°C te paraoa hei whakapūmau makariri, me 8-10°C te pata hei whakangawari, me 5-8°C te tiakarete hei whakatō, ā, me 0-4°C ngā mousse kua oti hei penapena. He uaua ki ngā wāhanga pouaka whakamātao me te pouaka tio anake te whakatutuki i ēnei hiahia motuhake. Koinei te wāhi e noho ai he wāhanga pāmahana rerekē motuhake hei āhuatanga nui mō ngā kaiwhaiwhai tunu kai.
Me whakarite kia tika te whakarerekētanga pāmahana maha-taumata i roto i te whānuitanga o te -7°C ki te 10°C i roto i tētahi wāhanga pāmahana rerekē-kounga. Hei tauira, ina whakamataohia te paraoa pokepoke mō te whakapūkara, whakatakotoria te wāhanga ki te 2°C. Mā tēnei ka āta whakapūkara, kāore e mutu nā te makariri rawa. Hei whakangawari i te pata, whakatikatika ki te 10°C. Mā tēnei ka taea te whakangawari haere i te pata i roto i te taiao pāmahana pumau kia tae rā anō ki tētahi āhua "ka ngāwari te tuku ki te pēhanga maihao me te kore e piri," he pai ake te pumau i te whakangawari i te pāmahana rūma—he tino whai hua i roto i te raumati, i ngā rūma hauhautanga rānei me ngā pāmahana rerekē.
I te nuinga o te wā, ko te wāhanga pāmahana rerekē te wāhi rokiroki motuhake mō ngā kai pirau pērā i te kirīmi whiu me te tiihi, hei ārai i te whakawhiti i ngā reka me te pupuri i tō rātou reka parakore.
3. He nui te kaha ki te whakamatao, inā koa he hoahoa āhua-pouaka
Kia tīmata koe ki te tunu kai i te kāinga, ka nui haere te hiahia ki te penapena i ngā kai me ngā hua kua oti: me penapena te kirīmi whiu, te tīhi kirīmi, ngā hua manu, te miraka, me ētahi atu kai; me penapena ngā kai tunua pēnei i te keke, te pihikete, me te taro ki roto i te pouaka hau; ā, i ētahi wā me whakamatao te paraoa pokepoke, ngā whakakī kua oti te whakarite rānei, hei whakamahi i muri mai. Mena he iti rawa te kaha rokiroki makariri o te pouaka whakamātao, ka tūpono koe ki ngā āhuatanga "kāore e tau ngā kai, ā, ka pēhia ngā kai tunua kia kore e rite te āhua," ka pā kino ki te wheako tunu.
Me whiriwhiri ngā kaihanga keke kāinga i ngā pouaka whakamātao he 250 rita te iti rawa te kaha whakamatao. Mō ngā whare nui ake, mō ngā tunu kai auau rānei, he nui ake te ngāwari o te kaha neke atu i te 300 rita. Haunga te kaha, me aro nui ki te pouaka whakamātao momo pouaka. Ki te whakatauritea ki ngā whata tuwhera, ka mau tonu ngā pāmahana pumau o ngā pouaka, ā, ka ārai i te whakawhiti i waenga i ngā kai. He tino pai tēnei mō te penapena paraoa e hiahia ana kia hiritia, ngā keke kua oti, me ngā mea rite. Kei ētahi pouaka pouaka whakamātao he mahi "tiaki haumākū teitei", e pupuri ana i ngā taumata haumākū tata ki te 90% i roto i te pouaka. He pai tēnei mō te penapena hua hou, huawhenua, me ētahi atu kai tunu (pērā i ngā rōpere, i ngā māngo rānei mō ngā keke hua), ka roa ake te ora o te pouaka, ā, ka ārai hoki i te maroke.
4. Te Whakatio i te Makuku Iti + Te Whakatio Tere: Te Hou Roa o ngā Kai
He maha ngā kaihanga keke kāinga e whakarite ana i ngā kai maha i mua i te wā, pērā i te pata tio, te paraoa tio, me ngā hua tio. Nā tēnei ka nui ake ngā whakaritenga mō ngā āheinga tio o te pouaka whakamātao. Me whakaatu e te mahi tio whai hua ngā āhuatanga matua e rua: te tio iti-haumākū me te tio tere.
Ka whakaitihia te makuku i roto i te wāhanga tio mā te tio iti-haumākū, ka ārai i te hanga hukapapa ki runga i ngā mata kai. Mēnā ka puta he hukapapa i te pata, i te paraoa pokepoke, i ētahi atu kai rānei, ka taea e te makuku nui i te wā e rewa ana te whakararu i te kakano me te reka. Hei tauira, ko te pata tio hukapapa e whakamahia ana i roto i ngā pihikete ka hua ake he paraoa pokepoke wai rawa, ā, he ngohengohe, he makuku ngā kai tunu. Ka tere te tio i ngā kai ki te pāmahana tio, ka tere te mau i ngā matūkai me te makuku i te wā e ārai ana i te kino o ngā pūtau. Ina tio ana i ngā hua hou, ka tiakina e te tio tere tōna kakano pakari, ka ārai i te hua kua rewa kia ngawari, kia wai rānei—he pai mō ngā tāte hua, mō ngā keke rānei.
Nō reira, he mea tino pai te whakamahi i tētahi wāhanga pouaka tio kua wehea te hoahoa. Ka taea te penapena motuhake i ngā momo kai tio rerekē, ā, ka ārai i te whakawhiti kakara, ka tere hoki te tiki mai.
5. Mahi Hou Ārai Kitakita, Tiaki i te Haumaru Kai
I roto i ngā kai tunu kai, he tino pirau ngā hua manu, te miraka, te tīhi kirīmi, me ērā atu mea pera, ā, he nui ngā matūkai, ka ngāwari ai te tipu o ngā huakita. Mēnā he huakita kei roto i te pouaka whakamātao, ka ngāwari te pirau, ehara i te mea ka pā ki te reka o ngā kai tunua engari ka tūpono pea he mōrearea ki te hauora. Nō reira, he mea nui te tiaki i te hou o ngā huakita hei whakaaro mā ngā kaihanga keke kāinga ina whiriwhiri ana i tētahi pouaka whakamātao.
Ko ngā hangarau patu huakita matua o nāianei mō te pouaka whakamātao ko te patu huakita hiriwa-iona, te patu huakita UV-violet, me te patu huakita photocatalytic. Ka ārai pai ēnei hangarau i te tipu o ngā huakita noa pēnei i te E. coli me te Staphylococcus aureus i roto i te pouaka whakamātao, ka whakaiti i te tūponotanga o te poke o te kai. He mea pai kia whiriwhiria ngā pouaka whakamātao kua tohua māramatia ki te "reiti patu huakita ≥99%" me te whakarite i ngā tauira me ngā rauemi kounga kai mō te arai o roto kia pai ake ai te haumaru o te kai.
Hei tāpiritanga, he mea nui te mahi hiri o te pouaka whakamātao. Mā te hiri piri ka ārai i te urunga mai o ngā huakita o waho, ā, ka whakaitihia hoki te ngaronga o te hau makariri, kia mau tonu ai te hou.
6. Mahi Mārire mō te Auahatanga Tunu Kai Kore e Whakararuraruhia
He maha ngā wā e hiahiatia ana te tunu kai kāinga i roto i te kīhini—mai i te whakarite kai, te pokepoke paraoa, me te whakapūkara ki te tunu me te whakamatao. Ka taea e te haruru nui o te pouaka whakamātao te whakararuraru i tō rere auaha, ā, ka whakararuraru hoki i te whakarongo ki ngā tohu nui o te oumu (pēnei i ngā whakatūpato otinga whakamahana, ngā huringa ngawari rānei i te wā whakapūkara paraoa).
Nō reira, ahakoa ehara te mahi mārire i te āhuatanga matua, he mea nui tonu hei whakapai ake i te wheako tunu kai.
Kōwhiria ngā pouaka whakamātao he haruru mahi ≤38dB—he rite ki te kōrero mārie—kia kore ai e whakararuraru i te whakamahinga o ia rā. I te wā e whiriwhiri ana, kia mōhio ki te momo pūwero: he maeneene ake, he mārie ake te oma o ngā pūwero hurihuri i ngā tauira auau-pūmau.
Ka pā anō hoki te whakaiti i te wiri o te pouaka whakamātao ki ngā taumata haruru. Mā ngā waewae whakaiti-wiri kounga teitei ka whakaitihia te wiri o te mahi, ka whakaitihia anō hoki te haruru.
Kei raro nei ngā tūtohutanga kōwhiringa rerekē
Whakaritea te "whakahaere pāmahana tika" me te "kaha whakamātao e rawaka ana." Kōwhiria he tauira taketake me te whakahaere pāmahana rorohiko me te kaha whakamātao ≥250L hei whakatutuki i ngā hiahia tunu kai o ia rā.
Kōwhiria ngā tauira he "wāhanga pāmahana rerekē motuhake" me te "tiaki i te hou o te paturopi." Ka taea te whakauru i te wāhanga pāmahana rerekē ki ngā momo tunu kai, ā, ka tiakina e te hangarau paturopi te haumaru kai, ka pai ake te utu.
Mō ngā tauira papai, me whakarite ngā āhuatanga pēnei i te "whakatio iti-haumākū + whakatio tere," "hangarau rere hau," me te "mahi hurihuri marino." Whakaarohia i te wā kotahi te kaha me te hoahoa o te wāhanga hei whakarei ake i tō wheako tunu kai.
Mā te arotahi ki ngā hiahia matua o te "tiaki kai" me te "whakarerekē i ngā horopaki," ka arotahi ki ēnei kaupapa matua e ono—te whakahaere pāmahana tika, te wāhanga pāmahana rerekē-motuhake, te kaha e ranea ana, te tio kounga teitei, me te mahi marino huakita—ka āwhina i a koe ki te whiriwhiri i tētahi pouaka whakamātao "e pai ana mō te tunu kai" e tika ana mō ō hiahia.
