Yiziphi izinto zokupakisha ezifanelekela iMishini Yokupakisha Ukudla Ekulungele Ukudla?

Isingeniso:

Ukudla okulungele ukudliwa sekuthandwa kakhulu ezweni lanamuhla elisheshayo, okunikeza lula nokudla okusheshayo kubantu abamatasa. Ngenxa yalokho, isidingo semishini yokupakisha esebenza kahle nethembekile eyenzelwe ngqo ukudla okulungele ukudliwa nayo ikhuphuke kakhulu. Le mishini idinga izinto zokupakisha ezifanele ezingagcina ubusha, ukunambitheka, kanye nekhwalithi yokudla ngenkathi iqinisekisa ukuphepha kwayo. Kulesi sihloko, sizohlola izinto zokupakisha ezahlukahlukene ezifanele imishini yokupakisha ukudla okulungele ukudliwa futhi sihlole izakhiwo zayo ezihlukile kanye nezinzuzo.

Izinto Zokupakisha Eziguquguqukayo

Izinto zokupakisha eziguquguqukayo zisetshenziswa kabanzi embonini yokudla okulungele ukudliwa ngenxa yokuguquguquka kwazo, ukusebenza kahle kwezindleko, kanye nekhono lokuhlangabezana nezindinganiso ezidingekayo zokuphepha kokudla. Lezi zinto zifaka:

1. Amafilimu epulasitiki:

Amafilimu epulasitiki, njenge-polyethylene (PE) kanye ne-polypropylene (PP), avame ukusetshenziselwa ukupakisha ukudla okulungele ukudliwa. Lawa mafilimu ahlinzeka ngezakhiwo ezinhle kakhulu zokuvimbela umswakama, ngaleyo ndlela avimbele ukudla ukuthi kungonakali ngenxa yokuchayeka emoyeni nasemswakeni. Ngaphezu kwalokho, anikeza ukuqina okuhle kokushisa, okuqinisekisa ubuqotho bokupakisha. Amafilimu epulasitiki alula, aguquguquka, futhi asobala, okuvumela abathengi ukuthi babuke kalula okuqukethwe. Kodwa-ke, kubalulekile ukukhetha amafilimu ebanga lokudla angenawo amakhemikhali ayingozi futhi ahambisana nezidingo zomthetho.

2. I-Aluminium Foil:

I-aluminium foil ingenye indlela ethandwayo yokupakisha ukudla okulungele ukudliwa. Ihlinzeka ngesithiyo esihle kakhulu ngokumelene nomoya-mpilo, ukukhanya, kanye nomswakama, ngaleyo ndlela iqinisekisa ukuthi ukudla kuhlala isikhathi eside eshalofini. I-aluminium foil imelana namazinga okushisa aphezulu, okwenza ifaneleke kokubili imikhiqizo yokudla eshisayo nebandayo. Ngaphezu kwalokho, inikeza indawo ekhanyayo esiza ukuvimbela ukudluliselwa kokushisa, igcine ukudla kumazinga okushisa afanele. Kodwa-ke, i-aluminium foil ingase ingafaneleki kuzo zonke izinhlobo zokudla okulungele ukudliwa, njengoba ingathinta ukunambitheka kanye nokuthungwa kwezinto ezithile zokudla ezithambile.

Izinto Zokupakisha Eziqinile

Nakuba izinto zokupakisha eziguquguqukayo zivame ukusetshenziswa ekudleni okulungele ukudliwa, kunezimo lapho izinto zokupakisha eziqinile zikhethwa khona. Izinto zokupakisha eziqinile zinikeza isivikelo esithuthukisiwe kanye nokuqina, okwenza zifaneleke kakhulu ezinhlotsheni ezithile zokudla. Nazi izinto ezimbili zokupakisha eziqinile ezisetshenziswa kabanzi:

3. Amathayi Namathileyi Epulasitiki:

Amabhavu namathileyi epulasitiki avame ukusetshenziselwa ukupakisha ukudla okulungele ukudliwa, ikakhulukazi kumasaladi, ama-dessert, kanye nokudla okunikezwa kanye kuphela. Ahlinzeka ngesakhiwo esiqinile esivikela ukudla ezintweni zangaphandle, njengemiphumela kanye nokungcola. Amabhavu namathileyi epulasitiki angenziwa ngezinto ezahlukene, okuhlanganisa i-PET (polyethylene terephthalate), i-PP (polypropylene), kanye ne-PS (polystyrene). Lezi zinto zinikeza ukucaca okuhle, okuvumela abathengi ukuthi babone okuqukethwe, futhi zingafakwa ilebula futhi zibekwe kalula ukuze zigcinwe futhi zithuthwe kahle.

4. Izitsha Zengilazi:

Kweminye imikhiqizo yokudla esezingeni eliphezulu nesezingeni eliphezulu elungele ukudliwa, izitsha zeglasi zivame ukuthandwa ngenxa yobuhle bazo kanye nombono womkhiqizo osezingeni eliphezulu. Izitsha zeglasi zinikeza izakhiwo ezinhle kakhulu zokuvimbela umoya-mpilo kanye nomswakama, okuqinisekisa ukuthi ukudla kusha futhi kunambitheka. Futhi azikwazi ukusabela, zigcina ukunambitheka kokudla ngaphandle kokunikeza noma yikuphi ukunambitheka okungafuneki. Kodwa-ke, izitsha zeglasi zinzima futhi zithambekele kakhulu ekuphukeni, okungakhuphula izindleko zokuhamba futhi kube nokukhathazeka ngokuphepha.

Izinto Zokupakisha Ezikhethekile

Ngaphezu kwezinto zokupakisha eziguquguqukayo neziqinile, kunezinto ezikhethekile eziklanyelwe ngqo izidingo ezihlukile zokudla okuthile okulungele ukudliwa. Lezi zinto zinikeza izixazululo ezenzelwe wena ukuze kugcinwe ikhwalithi nokuphepha kokudla. Nazi izibonelo ezimbili:

5. Izinto Zokupakisha Eziguquliwe Zomkhathi (i-MAP):

Izinto zokupakisha eziguquliwe ze-Atmosphere Packaging (MAP) zisetshenziselwa ukudala ukwakheka kwegesi okuguquliwe ngaphakathi kwephakheji yokudla, ngaleyo ndlela kwandise impilo yeshelufu yokudla okulungele ukudliwa. Lokhu kufezwa ngokushintsha amazinga egesi e-oxygen, i-carbon dioxide, ne-nitrogen. Izinto ze-MAP ngokuvamile zakhiwa amafilimu anezingqimba eziningi, ahlinzeka ngesithiyo ekungeneni kwe-oxygen nokuqinisekisa ukuthi ukudla kuhlala kusha. Ukwakheka kwegesi kungenziwa ngokwezifiso ngokuya ngezidingo zokudla ezithile, kuvimbele ukonakala futhi kugcinwe ikhwalithi ephezulu.

Isifinyezo:

Ekuphetheni, imishini yokupakisha ukudla okulungele ukudliwa idinga izinto zokupakisha ezifanele ezingagcina ubusha, ukunambitheka, kanye nekhwalithi yokudla ngempumelelo ngenkathi iqinisekisa ukuphepha kwayo. Izinto zokupakisha eziguquguqukayo ezifana namafilimu epulasitiki kanye ne-aluminium foil zinikeza izakhiwo ezinhle kakhulu zomswakama kanye nezivimbelo zomoya-mpilo, okwenza zifaneleke kakhulu ezinhlotsheni eziningi zokudla okulungele ukudliwa. Izinto zokupakisha eziqinile njengezitsha zepulasitiki, amathileyi, kanye nezitsha zeglasi zinikeza isivikelo esithuthukisiwe kanye nokuqina, zihambisana nezidingo ezithile. Izinto zokupakisha ezikhethekile njengezinto ze-MAP zandisa isikhathi sokuphila kweshelufu ngokushintsha ukwakheka kwegesi ngaphakathi kwephakheji. Ngokukhetha izinto zokupakisha ezifanele, abakhiqizi bokudla okulungele ukudliwa bangaletha imikhiqizo yabo kubathengi ngekhwalithi ephezulu kakhulu kanye nokulula.
