Te Arotau i te Tākai DJVAC: Te Kōwhiri i ngā Rauemi Tika o te Pēke Korehau

Tirohanga Whānui mō ngā Rauemi Tākai me te Pēke Korehau

Ngā mīhini tākai korehau (rūma or ngā momo momi) tango hau mai i ngā pēke hua, i ngā rūma rānei i mua i te hiri i ngā pēke hei aukati i ngā hau o waho. Ka roa ake te ora o te taonga mā te whakawhāiti i te pānga ki te hāora me te aukati i te tipu o ngā huakita pirau, me te whiriwhiri i ngā pēke korehau i runga i ngā āhuatanga pēnei i ngā āhuatanga ārai, te roa me te mahi hiri wera – ko te tikanga he maha ngā paparanga o ngā paparanga kirihou kua hiritia i runga i ngā paearu motuhake pēnei i te tiaki ārai hāora/makuku, te ātete wera, te mārama me te pakari o te poka.

Pēke Korehau Nailoni/PE (PA/PE)

* Te Hanganga me ngā Āhuatanga: Kei roto i ngā putea PA/PE he paparanga o waho o te nairona (polyamide) kua whakakikoruatia ki te paparanga hiri o roto o te polyethylene hei ātete ki te poka, hei tiaki i te arai hāora/kakara, me te hiri wera kaha ahakoa i ngā pāmahana iti iho i ngā kiriata PE noa. Ki te whakatauritea ki ngā kiriata PE noa, he nui ake ngā arai hāora/kakara me te ātete poka o ngā papa PA/PE, e mau tonu ana ō rātou āhua puta noa i ngā tukanga hanga wera-huka hohonu, me te tu atu ki te wera ngawari i te wā e hiritia ana.

* Ngā Whakamahinga: He maha ngā wā ka whakamahia ngā putea PA/PE mō ngā hua mīti hou me ngā hua tio (mīti kau, poaka, heihei me ngā kaimoana) nā te mea he ātete ngā taha wheua me ngā wahi koi o te nairona; ka āwhina tēnei ki te pupuri i ō rātou tae me te reka i te wā e rongoatia ana i roto i te makariri mō te wā roa. He pai hoki mō ngā hua tiihi me ngā hua deli hei pupuri i te reka me te kakano mā te whakaiti i te urunga o te hāora; ka taea e tō rātou kiriata pakari te tākai i ngā mīti tukatuka pērā i ngā pate. Ka taea hoki te rere i ngā ranu haurua-wai mā roto i ngā putea PA/PE nā te mea he paparanga hiri kaha e ārai ana i te turuturu me te pupuri i ngā kakara - he tino pai mō ngā wā rokiroki makariri roa! I roto i te poto, he pai ngā putea PA/PE mō ngā kai he taha koretake, he taha mārō rānei (wheua/maramara mīti, maramara mīti, maramara mīti), he roa te wā whakamatao/whakatio e hiahiatia ana - he tino pai!

* Ētahi atu Whakamahinga: He maha atu ngā whakamahinga o ngā papa PA/PE i tua atu i te kai, pērā i te takai hauora me ngā wāhanga ahumahi. Ka taea te whakahoromata me te hiri i tō rātou kiriata ārai-teitei hei hanga kete hauora; ka whakamahia e te takai hiko hei whakahaere i te makuku me te tāpiri i te kaha miihini, ā, ka taea te tāpiri i ngā paparanga ārai-pūmau, ārai rānei mō ngā papa hiko, ngā takai taputapu rānei. Hei whakamutunga, ka whakaratohia e ngā putea PA/PE he kiriata pono e kaha ana te ārai me te ātete poka, ā, he mea pai rawa atu mō ngā hiahia takai korehau whānui.

Pēke Korehau Polyester/PE (PET/PE)

*Te Hanganga me ngā Āhuatanga: Ko ngā putea polyester/PE (e kiia ana ko ngā putea PET/PE, PET-LDPE rānei) e whakamahi ana i tētahi paparanga PET o waho me tētahi paparanga PE o roto hei hanganga. He pai rawa atu ngā ārai matū, wera me te hāora a te PET, ā, ko tōna kaha he 5-10x teitei ake i te kaha kume o te PE; hei tāpiritanga, ka taea e ia te pupuri i ngā āhuatanga ā-tinana i runga i te whānuitanga o te pāmahana, ka hoatu ki ēnei putea he āheinga ārai mārama (e whakarato ana i te māramatanga me te ātete poka ngāwari; engari mō ngā taonga he tino koi ngā pito, he pai ake pea te whakamahi i ngā paparanga nairona).

* Ngā Whakamahinga: He pai rawa ngā pēke korehau PET/PE mō ngā taonga e hiahia ana kia mārama, kia ātete hoki ki ngā matū, pērā i te mīti kua tunua, kua auahi rānei, me te ika e hiahia ana kia kitea whānuitia mō ngā take kounga o te takai. Nā te pakari o ēnei pēke ka taea te hiri i te wera i runga i ngā mīhini aunoa; nā te āhua pumau o te pāmahana o te PET, ka mahi pai rātou i roto i ngā taiao pouaka whakamātao me ngā taiao hauhautanga (hei tauira, he pīni kawhe kua tākai korehau, he mea kakara rānei). Hei tāpiri, he maha ngā wā ka whakamahia hei kiriata matua i roto i ngā raina takai korehau hanga-mahana (mā te whakamahi i ngā tukutuku hanga PA/EVOH/PE).

* Tuhipoka Hangarau: Mā te ārai kaha o te Polyester ki ngā hau ka āwhina i te pupuri i te kakara, engari kāore te PET/PE parakore i te ārai hāora hohonu me te pakari o te werohanga o te PA/PE. Nō reira, he pai ake pea te PET/PE mō ngā hupa, ngā paura, me ngā kai māmā kua takai ki te korehau nā te mea he ngawari ake, he māmā ake rānei te hanganga; e kī ana a carePac he kaha ake te parenga o te polyester, o te nairona rānei i ngā werohanga, ā, he pai hoki te PET/PE mō te hiri korehau. I roto i te mahi, he maha ngā tukatuka e whiriwhiri ana i te PET/PE mō ngā hua roa-roa me ngā kakano whakairo (mēnā kei te whakamahi i ngā mīhini momi) hei whakarei ake i ngā āheinga hiri; he tino pai te mahi a ēnei putea ina whakamahia ngā waeine rūma (tērā pea he taumata korehau teitei). He hototahi ngā putea PET/PE ki ngā mīhini takai korehau katoa; he tino pai ngā waeine rūma ki te whakaputa i ngā taumata korehau nui ake i ētahi atu mīhini takai korehau (tērā pea he taumata korehau teitei).

Ngā Kiriata Paparanga Maha-Ārai-Teitei (EVOH, PVDC me ētahi atu)

Ka whakaratohia e ngā Kiriata Paparanga Maha-Ārai-Teitei (EVOH, PVDC me ētahi atu) he parenga whai hua mai i te urunga mai o ngā poke kino ki te taiao.

*Ngā Pēke EVOH: Mō te roa o te oranga o te papa, ka whakaratohia e ngā paparanga maha-paparanga e whakauru ana i te kapia ārai EVOH (waipiro ethylene-vinyl) te roa o te oranga o te papa me te ārai i te ngaronga o te hua. Ko ngā hanganga noa mō ēnei paparanga ko PA/EVOH/PE, PE/EVOH/PE rānei, me te matua EVOH e whakarato ana i te tere tuku hāora tino iti, ko te nairona, ko te PET rānei e whakarato ana i te kaha miihini me te hiri – ka puta he ārai teitei tino pai i tēnei huinga: Ka whakaroa rawa ngā pēke EVOH i te waikura me te hekenga makuku, me te tāpiri i te kaha miihini. E ai ki ngā pūrongo a ngā tohunga, ka āwhina ēnei paparanga ki te whakatutuki i te roa o te oranga o te papa i roto i te pouaka whakamātao, i te tio rānei, me te whakaiti i te ngaronga o te hua ki ngā paparanga PA/PE.

*Ngā Āhuatanga: He mārama, he ngāwari hoki te kiriata EVOH, engari i roto i ngā putea korehau ka hunaia e ngā paparanga mātotoru e huna ana i a ia. Ka mau tonu te pumau o te hiri o ēnei putea i te wā e tio ana, ko te PE ia e tiaki ana i te EVOH mai i te kino o te makuku; ko te pakari o te werohanga mai i ngā paparanga PA he nui ake i te PA/PE noa iho, me te kore e whakararu i te kaha o te hiri.

* Ngā Whakamahinga: He huarahi pai ngā putea korehau ārai-teitei a EVOH ki te tuku mīti hou/tio me ngā kaimoana i tawhiti, me te penapena mō te wā roa. He huarahi pai hoki ngā putea korehau EVOH ki te tiaki i ngā kai utu nui, ngā kai tairongo-hāora rānei pērā i te tīhi, te nati, ngā hua maroke, ngā kai kua oti te whakarite me ngā ranu kounga teitei mai i te ngaronga hāora, te pirau rānei i te wā e kawe ana, e penapena ana rānei. Me whai whakaaro tonu ki te putea EVOH ina me pupuri tonu te tiakitanga o te kounga (tae, reka, kakano rānei); arā, whakamahia i ngā wā e hiahia ana ngā hua sous vide ki ngā āhuatanga pai rawa atu i te wā e kawe ana, e hiahia ana rānei ki te penapena taonga mō te wā roa!

*Ētahi atu Ārai: He iti te uruhanga o te O2 ki ngā kiriata pania PVDC e whakamahia ana i roto i ētahi pēke tīhi, mīti rānei kua rongoatia; heoi, kua whakawhāitihia te whakamahinga e ngā take ture me ngā take tukatuka. Ka whakapai ake hoki ngā kiriata whakarewa korehau (PET, PA rānei kua pania ki te konumohe) i te mahi ārai (tirohia te wāhanga e whai ake nei).

Pēke Korehau Konumohe (Kua Whakarewahia)

He maha ngā wā ka whakamahia ngā putea konumohe kua whakakikoruatia ki te takai korehau hei tiaki pai rawa atu i te kawhe, te tī, ngā mea kakara rānei. Ka hangaia e ngā paparanga pepa konumohe i roto i te putea he ārai whai hua ki te mārama, te hāora me te makuku – he mea pai mō te pupuri i te hou o te kawhe mō te wā roa! E toru ngā paparanga o ngā putea pepa konumohe e ārai ana i te mārama, te hāora me te makuku: PET/AL/PE, PA/AL/PE rānei – ka ārai te kiriata PET o waho i te poka, ā, ka kaha te poka, ka ārai te pepa konumohe AL i te hau me te mārama, ā, ka whakarite te PE i te hiri wera ma – ko te mutunga mai, kāore rawa he hau, he makuku rānei e taea te uru!

* Ngā Āhuatanga: Ka taea e ngā pēke konumohe-whakakirikiri te pakari engari ka taea te hanga; ka whakaata i te wera me te mārama, ka tiaki i ngā hihi UV me ngā huringa pāmahana, me te noho pōuri kia noho huna ai ngā mea o roto i te wā e maroke ana, e kore hoki e waikura ngā hua. Hei tāpiri, he pai te mahi a ngā pēke konumohe whakakirikirikiri i roto i ngā pouaka tio hohonu, i ngā taiao whakakī wera rānei (kia mōhio koe kāore e taea te haumaru i ngā pēke konumohe ki te oumu me te kore he maimoatanga motuhake).

* Ngā Whakamahinga: Ka taea te whakamahi i ngā putea pepa konumohe hei tiaki i ngā taonga utu nui, ngā taonga pirau rānei pērā i te kawhe me te tī (hei pupuri i te kakara me te hou), ngā kai paura, ngā kai maroke-tio rānei, ngā nati, me ngā otaota. I roto i ngā ratonga kai, he maha ngā wā ka whakamahia e ngā putea sous vide/kohua-i-roto-i-te-pēke te pepa konumohe; he pai mō ngā rongoā/huaora/tāpiritanga/huaora me ētahi atu. Hei tāpiri, ka roa ake te pupuri i te reka o ngā rau tī kua tākai-korehau ina rongoatia ki roto i te pepa konumohe, ki te whakaritea ki ngā takai kirihou (hei tauira) he tauira noa iho tēnei e whakaaturia ana i konei!

* Hototahi ki ngā Mīhini: He maeneene te nuinga o ngā putea pepa konumohe, ā, i ētahi wā ka hiritia mā te whakamahi i ngā mīhini taumaha, kia pai ai ngā mīhini takai korehau o waho DJVAC mō te whakahaere i ēnei putea me te kore raruraru.

Ngā tono ahumahi me ngā tono pūranga.

He nui ake ngā whakamahinga o ngā putea korehau ārai-teitei i te kai anake:

Ngā Hikohiko me ngā Wāhanga Whakarewa: E ai ki te kōrero i mua ake nei, ka tiakina e ngā putea korehau mō ngā hikohiko me ngā wāhanga whakarewa ngā wāhanga tairongo-makuku i te wā e tukuna ana. Ina honoa ki te whakamaroke, ka whakaratohia e ngā taiao korehau he taiao kāore he waikura, he waikura rānei i te hau o ngā wāhanga whakarewa. He rerekē ki te kai, ka taea hoki te horoi i ngā putea korehau PA/PE, pepa konukōre rānei ki te hauota i mua i te hiri mā te whakamahi i ngā mīhini DJVAC kei roto ngā kōpiri me ngā mana whakahaere tika hei whakahaere i ngā putea pepa konukōre matotoru, ngā putea konumohe rānei.

* Te Tiaki Tuhinga: Mō te tiaki tuhinga tino pai, ka whakamahia e ngā pūranga ngā kiriata korehau kua hiritia ki te korehau pērā i te polyethylene, te polyester/Mylar rānei hei aukati i te hāora me ngā pepeke, ka hangaia he putea ārai-hau hei karo i te kōwhai me te tipu o te harore i roto i ngā tuhinga pepa. Pērā i te takai kai, mā te whakawhāiti i te hāora ka roa ake te ora – ka roa ake te ora o ngā tuhinga i te takai ārai-hau, pērā i te roanga atu ki ngā hua kai.

* Rongoā me te Hauora: Me hiritia ngā kete hauora parakore ki te korehau mā te whakamahi i ngā putea ārai-teitei me ngā putea PA/PE kei roto ngā kohao haehae kia māmā ai te whakatuwhera, me te tutuki i ngā paerewa FDA, hauora rānei.

I ia o ēnei āhuatanga, he mea nui te whakamahi i te kiriata kua whakatauria mō te taiao o te hua (hei tauira, kāore he halogen mō ngā hikohiko, ngā tuhinga kounga pūranga rānei). Ka taea e ngā mīhini korehau DJVAC te whakauru i ngā rahi rerekē o te raranga putea; me tohu e ngā kiritaki ko tēhea kiriata e hiahiatia ana e rātou ina tuku ota mai ki a mātou.

Me pēhea te whiriwhiri i ngā rauemi o te pēke korehau

Whakaarohia ēnei āhuatanga i te wā e whiriwhiri ana i te rauemi mō te pēke korehau:

*Ngā Hiahia Ārai: He aha ngā āhuatanga e tika ana kia noho hou tonu te hua? Mō ngā whakamahinga pouaka whakamātao mō te wā poto, he rawaka pea ngā putea PA/PE, PET/PE rānei; mō ngā hua tio e rongoatia ana mō ngā marama maha, mō ngā hua tino tairongo rānei e hiahia ana kia tiakina mai i te tuku hāora, whakamahia ngā papa EVOH me ngā tere tuku O2 tino iti.

* Te Parenga Ā-Mīhini: He koi ngā taha o tō taonga, he kaha rānei te pupuri? Whakatairangahia te ātete ki ngā poka (ngā paparanga momona i te nairona, ngā whakairo rānei). Me kaha ake ngā kiriata mō ngā wāhanga ahumahi nunui, ngā mīti kua whai wheua rānei.

* Tikanga Hiri: Ka whakamahia e ngā pēke korehau te hiri wera hei tikanga matua mō te hiri. Ko te PE (LDPE, LLDPE rānei) te mea e whakamahia whānuitia ana hei rauemi hiri, me rite te awhe pāmahana hiri ki ērā o ngā pae wera o tō mīhini kia tika ai ngā hua hiri. Ko ētahi kiriata ārai teitei ka hiahia pea ki ngā pāmahana hiri teitei ake, ki te pēhanga kume nui ake rānei kia tika ai te piri.

* Te Haumaru Kai me ngā Ture: Whakamahia ngā kiriata kai kua whakaaetia e te FDA/GB ina tuku taonga ki ngā mākete o tāwāhi; ka mahi tahi a DJVAC me ngā kaiwhakarato putea e tuku ana i ngā rauemi whaimana mō tēnei kaupapa. Ina hoko kiriata e haere ana ki tāwāhi, me whai tuhinga ture anō hoki.

* Tātari Utu/Mahinga: He nui ake te utu o ngā putea EVOH, ngā putea pepa whakarewa rānei; arotakehia te utu e pā ana ki ngā whakaritenga roa o te rokiroki – hei tauira, ko ngā nati kua tākaihia ki te korehau e hiahiatia ana hei kaweake ka pai ake pea tēnei momo, engari ko ngā pouaka tio kāinga ka pai ake pea ki ngā putea PA/PE māmā ake.

He maha ngā wā ka whakahaerehia e ngā tukatuka ngā whakamātautau mā te whakamahi i ngā putea tauira e whakaratohia ana e ngā kaihanga, ko ētahi ka whakarato i ngā rōra whakamātautau, i ngā pepa rānei ki ngā kaihoko hei whakamātautau mā te kaihoko. I te wā e hanga ana i te hanganga e hiahiatia ana e koe mō tō hua (hei tauira, "ngā wahi heihei tio"), tohua mai tōna roanga o te wā e hiahiatia ana, te tikanga takai me te roanga o te wā e hiahiatia ana hei āwhina i te whakatau i tōna hanganga e taunakitia ana.
