Komabe, kusinthasintha kwa zida zonyamula katundu kukukulirakulira, anthu ambiri amadabwa ngati filimu yotambasula ingagwiritsidwenso ntchito posungira chakudya ndikusunga. Kodi filimu yotambasula ndiyoyenera kusunga chakudya chatsopano, kapena pali njira zina zabwinoko?
Tiyeni tifufuze za filimu yotambasula, yomwe ikugwiritsidwa ntchito, komanso ngati ingagwiritsidwe ntchito bwino ngati chakudya.
Kodi Stretch Film ndi chiyani?
Filimu yotambasula, yomwe imadziwikanso kutikutambasula kulunga, ndi mtundu wa filimu yapulasitiki yopangidwa makamaka kuchokeralinear low-density polyethylene (LLDPE). Imadziwika ndi zakekutambasuka, zomwe zimalola kuti azikulunga molimba pazinthu, kupanga malo otetezeka, otetezera. Mafilimu otambasula amagwiritsidwa ntchito kwambiri m'mafakitale mongamayendedwe, nkhokwe,ndikupangakuti akhazikitse ndi kusonkhanitsa katundu panthawi yotumiza ndi kusunga.
Ngakhale filimu yotambasula idapangidwa kuti ikulungire zinthu mwamphamvu, kuti zisasunthike kapena kuonongeka panthawi yodutsa, anthu ambiri angadabwe ngati katundu wake amapangitsa kuti ikhale yoyenera kukulunga chakudya.
Kodi Mafilimu Otambasula Angagwiritsidwe Ntchito Pachakudya?
Mwachidule, inde, kutambasula filimu kungagwiritsidwe ntchitokunyamula chakudyamuzochitika zina, koma ndi zinamfundo zofunika.
1. Chitetezo Chakudya
Filimu yotambasula imapangidwa kuchokera kuzinthu zomwe nthawi zambiri zimaganiziridwazotetezeka ku chakudya. Mafilimu ambiri otambasula amapangidwa ndipolyethylene yotsika kwambiri (LDPE)kapenalinear low-density polyethylene (LLDPE), onse awiri aliFDA-yovomerezekakukhudzana mwachindunji chakudya mu ntchito zina. Izi zikutanthauza kuti Tambasula filimu angagwiritsidwe ntchito kuzimata chakudya ngati chikugwirizana ndi mfundo zofunika chitetezo chakudya.
Komabe, ndikofunikirafufuzaningati filimu yotambasula yomwe mukugwiritsa ntchitochakudya-kalasi. Sikuti mafilimu onse otambasula amapangidwa poganizira zachitetezo cha chakudya, ndipo ena amatha kukhala ndi mankhwala kapena zowonjezera zomwe sizoyenera kusungira chakudya. Onetsetsani kuti filimu yotambasula yomwe mumagwiritsa ntchito imalembedwa kutichakudya chotetezedwakapenaFDA-yovomerezekakukhudzana mwachindunji ndi chakudya.
2. Mwatsopano ndi Kusungidwa
Imodzi mwa ntchito zoyamba za kutambasula filimu ndi kupangachosindikizira chopanda mpweyakuzungulira zinthu. Izi zitha kukhala zothandiza pakuzimatazipatso, ndiwo zamasamba, ndi zakudya zopatsa thanzi. Kukulunga kolimba kungathandize kuchepetsa kukhudzana ndi mpweya, zomwe zingathandizenso kuchepetsa kuwonongeka mwa kuchepetsa kutaya kwa chinyezi ndi kuipitsidwa. Komabe, mosiyana ndi zida zapadera zopangira chakudya, filimu yotambasula ilibe zofananachotchinga chinyezikatundu, zomwe zingakhale zofunika kusunga chakudya kwa nthawi yaitali.
Kuti musunge nthawi yayitali, mungafune kuganizira njira zina, mongakusindikiza vacuum, popeza imapereka chisindikizo chodalirika chopanda mpweya komanso chitetezo chabwino ku chinyezi ndi kutentha kwafiriji.
3. Zosavuta komanso Zosiyanasiyana
Filimu yotambasula ndi yosinthika modabwitsa ndipo imatha kugwiritsidwa ntchito kukulunga mitundu yosiyanasiyana yazakudya, monganyama, tchizi, masamba, zipatso,ndizinthu zophikidwa. Zitha kukhala zothandiza makamaka mumalonda chakudya phukusindikulongedza katundu wambirikumene zakudya ziyenera kuikidwa pamodzi ndi kutetezedwa panthawi ya ulendo kapena kusunga.
Chifukwa filimu yosangalatsazowonekera, imathandizanso kuti zinthu zokulungidwa ziwoneke mosavuta, zomwe zingakhale zosavuta posunga chakudya kuti chizizindikiritse mwamsanga.
4. Kusunga ndi Kusamalira
Filimu yotambasula imapereka akukulunga kolimba, kotetezeka, zomwe zimathandiza kuti zakudya zisawonongeke ndi zowononga. Ndiwothandiza makamaka pakukulunga zinthukusungirako kwakanthawi kochepa, monga zafirijikapenakuzizira.
Komabe, ngakhale filimu yotambasula ingathandize kusunga chakudya kwakanthawi kochepa, sizothandiza pakusungamulingo woyenera kutsitsimukapoyerekezera ndi zinthu zina zomwe zimapangidwira makamaka kusunga chakudya, mongakukulunga chakudya cha pulasitikikapenazojambulazo. Komanso, kutambasula filimu alibechitetezo champhamvukapenakupumazofunika kwa zinthu ngatimkate watsopano, yomwe ingafunike kutuluka kwa mpweya kuti iteteze nkhungu.
5. Nkhani Zomwe Zingatheke ndi Mafilimu Otambasula a Chakudya
Ngakhale kutambasula filimu ndi yabwino, pali ochepapansikugwiritsa ntchito posungira chakudya:
Kupuma Mochepa: Monga tanenera kale, ngakhale filimu yotambasula ingathandize kuti chakudya chikhale chatsopano kwa kanthawi, sichilola kuti mpweya uziyenda. Izi zitha kukhala zovuta pazakudya zina, monga zokolola zatsopano, zomwe zimafuna kuti mpweya ukhale wabwino kwa nthawi yayitali.
Kukhalitsa: Kanema wotambasula nthawi zambiri amakhala wowonda kuposa zofunda zina, zomwe zikutanthauza kuti sizingateteze kwambiri zakudya zosakhwima. Ngati sichisamalidwa bwino, imatha kung'ambika kapena kusweka, zomwe zingawononge chakudya.
Osabwino Kuzizira: Ngakhale filimu yotambasula ingagwiritsidwe ntchito pozizira chakudya, sichipereka chitetezo chofananakuwotcha mufirijimonga matumba apadera oziziritsa kukhosi kapena zoyikapo vacuum-seal.
Njira Zina Zotambasulira Kanema Pakuyika Chakudya
Ngati mukuda nkhawa ndi kuchepa kwa filimu yotambasula posungira chakudya, lingalirani njira zotsatirazi:
Kumanga Manga: Mosiyana ndi filimu yotambasula, kukulunga (kotchedwansopulasitiki) amapangidwa makamaka kuti azidya. Ili ndi achikhalidwe chomamatirazomwe zimamatira kumalo a chakudya, kupanga chisindikizo cholimba kuti chakudya chikhale chatsopano. Imapezeka mu zonse ziwirichakudya-kalasindimalondamagiredi.
Zikwama za Vacuum Sealer: Kusungirako nthawi yayitali, kusindikiza vacuum ndi imodzi mwa njira zothandiza kwambiri zosungira chakudya pochotsa mpweya ndi chinyezi. Matumba a vacuum sealer amapangidwa kuti asatenthedwe mufiriji ndikuwonjezera moyo wa alumali wachakudya.
Pepala la Foil ndi Zikopa: Zakudya zamitundu ina, makamaka zomwe mukufuna kuziphika kapena kuzisunga mufiriji,zojambulazokapenapepala la zikopaangapereke chitetezo chabwinoko ku kutaya chinyezi ndi kuipitsidwa.
Zotengera Zagalasi kapena Zotengera Zapulasitiki Zopanda BPA: Posunga chakudya kwa nthawi yayitali, kugwiritsa ntchito magalasi osatulutsa mpweya kapena zotengera zapulasitiki ndi njira yodalirika kuposa zokulunga zapulasitiki. Zotengerazi zitha kugwiritsidwanso ntchito, zomwe zimapangitsa kuti zisawononge chilengedwe.
Kutsiliza: Gwiritsani Ntchito Mafilimu Otambasula Mosamala Pazakudya
Pomaliza,kutambasula filimuangagwiritsidwe ntchito posungira chakudya, koma si nthawi zonse njira yabwino kutengera chakudya chapadera komanso nthawi yosungira yomwe mukufuna. Ngati agwiritsidwa ntchito moyenera komanso m'malo otetezedwa ndi chakudya, filimu yotambasula ingathandize kuwonjezera moyo wa alumali wazinthu zina, makamaka posungira nthawi yochepa. Komabe, posungira nthawi yayitali kapena zinthu zofewa kwambiri, pali njira zina zopangira zabwinoko zomwe zilipo.
Kuti mupeze chakudya chotetezeka komanso chothandiza kwambiri, nthawi zonse onetsetsani kuti zomwe mumagwiritsa ntchito ndichakudya-kalasindipo amakwaniritsa zofunikira zachitetezo.
Ngati mukufuna kudziwa zambiri za filimu yotambasula ndi kugwiritsa ntchito kwake m'magawo osiyanasiyana, omasuka kupita patsamba lathuPano. Timapereka zinthu zosiyanasiyana zomangirira zomwe zimapangidwira zosowa zosiyanasiyana.
