Kupu Whakataki: Te Aranga Ake o ngā Pēke Ziplock PE i roto i te Tiaki Kai Hou
I tēnei ao tere o ēnei rā, ehara i te mea ko te whakaroa noa i te roa o te wā e penapenahia ai ngā kai – engari he mahi nui hei pupuri i te hauora me te haumaru. Mai i ngā kīhini pukumahi ki ngā mahi whakangahau o waho, he nui te hiahia mō ngā otinga e whakataurite ana i te whakamarie me te akuaku.Ngā putea ziplock kai PE(ngā putea polyethylene ziplock) kua puta hei whiringa matua mō ngā whare me ngā umanga kai, nā ō rātou āhuatanga rauemi ahurei. E tūhuratia ana e tēnei tuhinga te take e tū ai te PE hei "kaitiaki haumaru" i roto i te rokiroki kai me tōna uara mahi tino pai.
Ngā Painga o te Rauemi PE: Te Haumaru me te Mahi i Whakakotahitia
1.Kore-Paitini & Kua Tiwhikete Kai-Paitini
Ko te PE (polyethylene) anake te kirihou e whakamahia whānuitia ana kua whakamanahia e teFDA mō te whakapā atu ki te kai. Mā tōna hanganga ngota pumau ka kore he matū whakapūmau, he BPA, he matū kino rānei kei roto. Ahakoa te penapena kai pēpi, te whakamahana anō rānei i ngā hupa, kāore he paitini e tukuna ana e ngā putea PE, e whakamana ana i te haumaru mai i te hanga ki te whakamahinga o ia rā.
2.Hangarau Hiri-Papa-Toru
Kei roto i ngā putea PE ziplock he zipper reti kua whakamanahia me te katinga kakano mōārai-hau, ārai-wai, ā, ārai-huakita hoki:
- Ka ārai i te hāora hei whakaroa i te waikura (hei tauira, te ārai i te parauri o ngā hua).
- Ātete ana i te makuku kia mau tonu ai te pakari o ngā kai maroke.
- Mā ngā taha hiri-rua ka ārai i te whakawhiti parahanga i roto i ngā pouaka whakamātao.
3.Ātete ki te pāmahana tino nui (-40°C ki te 110°C)
Mā te ngāwari o te PE ka pono tonu i roto i ngā āhuatanga uaua:
- Haumaru ki te pouaka tioĀtete ki te pakaru ahakoa i te -40°C, ka taea te tiaki i te mīti mō te 3 marama.
- Ātete weraHe pai mō te ngaruiti hei whakarewa (mana iti/waenga) hei whakamahi rānei hei paparanga ā-wai mō te tunu kai sous-vide.
Whakataurite Rauemi: He aha te PE i pai ake ai i ngā momo kē atu
| Rauemi | Haumaru | Utu | Ngā Whakamahinga Pai rawa atu |
|---|---|---|---|
| PE | Kāore e paitini, ka taea te whakamahi anō | $0.04-0.07/pēke | Te rokiroki i ia rā, te whakatio, te haereere |
| PVC | He mea hanga ki te hauota, he mea mōrearea | $0.03-0.06/pēke | Ahumahi (ehara i te kai) |
| Hiraka | Haumaru engari ka ngawari te paru | $0.70-1.10/pēke | Tunu i te wera nui, whakamahia anō |
Kia mōhio: He iti te PVC mō ngā takai kai i roto i te EU nā te mea ka tukuna pea te dioxin.
