Hoʻolauna: Ka piʻi ʻana o nā ʻeke PE Ziplock i ka mālama ʻana i nā meaʻai hou
I kēia ao wikiwiki o kēia au, ʻaʻole wale ka mālama ʻana i ka meaʻai e pili ana i ka hoʻolōʻihi ʻana i ke ola o ka papa mālama meaʻai—he hana koʻikoʻi ia no ka mālama ʻana i ke olakino a me ka palekana. Mai nā lumi kuke home paʻahana a hiki i nā huakaʻi waho, ʻo nā hoʻonā e kaulike ana i ka maʻalahi a me ka maʻemaʻe ke koi nui ʻia nei.Nā ʻeke ziplock meaʻai PE(nā ʻeke ziplock polyethylene) ua kū mai ma ke ʻano he koho kiʻekiʻe no nā ʻohana a me nā ʻoihana meaʻai, mahalo i ko lākou mau waiwai kūikawā. Ke nānā nei kēia ʻatikala i ke kumu e kū ai ʻo PE ma ke ʻano he "kahu palekana" i ka mālama ʻana i ka meaʻai a me kona waiwai kūpono ʻole.
Nā Pōmaikaʻi Mea PE: Palekana a me ka Hana i Hoʻohui ʻia
1.Palapala hōʻoia ʻole ʻawahia a me ka papa meaʻai
ʻO PE (polyethylene) wale nō ka palakiko i hoʻohana nui ʻia i hōʻoia ʻia e kaFDA no ka hoʻopili ʻana i ka meaʻai. ʻO kona ʻano molekala paʻa e hōʻoiaʻiʻo ana ʻaʻohe ona plasticizers, BPA, a i ʻole nā kemika ʻino ʻē aʻe. Inā paha e mālama ana i ka meaʻai pēpē a i ʻole e hoʻomehana hou i nā sopa, hoʻokuʻu nā ʻeke PE i nā mea ʻawahia ʻole, e hōʻoiaʻiʻo ana i ka palekana mai ka hana ʻana a hiki i ka hoʻohana ʻana i kēlā me kēia lā.
2.ʻenehana sila ʻekolu papa
Loaʻa i nā ʻeke ziplock PE kahi zipper paheʻe i hoʻopaʻa ʻia a me ka pani ʻana i hana ʻia nopale ea, pale wai, a me ka palekana antibacterial:
- Hoʻopale i ka oxygen e hoʻolohi i ka oxidation (e laʻa, e pale ana i ka browning o nā hua).
- Kū'ē i ka makū e mālama i nā mea malo'o i ka ʻōlinolino.
- ʻO nā ʻaoʻao i sila pālua ʻia e pale aku i ka haumia kea i loko o nā pahu hau.
3.Ke Kū'ē Mahana Loa (-40°C a i 110°C)
ʻO ka maʻalahi o PE e hōʻoiaʻiʻo i ka hilinaʻi i nā kūlana paʻakikī:
- Palekana i loko o ka pahu hauKūpaʻa i ka māwae ʻoiai ma -40°C, e mālama ana i ka ʻiʻo a hiki i 3 mahina.
- Kūpaʻa welaPalekana no ka hawewe microwave no ka hoʻoheheʻe ʻana (mana haʻahaʻa/waena) a hoʻohana paha ma ke ʻano he papa pale wai no ka kuke ʻana sous-vide.
Hoʻohālikelike Mea: No ke aha ʻoi aku ka maikaʻi o ka PE ma mua o nā koho ʻē aʻe
