Ukupakishwa kwevacuum kuvame kakhulu ekuphileni kwansuku zonke, kusukela emashalofini ezitolo ezinkulu kuya emikhiqizweni eshisayo ku-inthanethi, ukudla okufakwe ku-vacuum kubonakala sekuwuphawu lokuphishekela kwabantu besimanje ukunethezeka nokuphepha. Kodwa ekuphileni kwansuku zonke, sivame ukuthola ukuthi ngemva kokusetshenziswa kokufakwa kwe-vacuum, ukudla kusawohloka ngokushesha, kungani lokhu? Ungakugwema kanjani?
Okokuqala, ake sibheke isimiso sokupakisha i-vacuum. I-vacuum packaging ubuchwepheshe bokupakisha ukudla obunweba isikhathi seshelufu sokudla ngokukhipha umoya ongaphakathi kwephakeji ukuze kwakheke isimo se-vacuum. Le ndlela yokupakisha inganciphisa ukuthintana kokudla ngomoya, umswakama kanye nama-microorganisms ngesikhathi sokugcinwa nokuthutha, ukunciphisa i-oxidation, isikhutha kanye nokukhula kwamagciwane kokudla. Ukufakwa kwe-vacuum kuvame ukusetshenziswa enyameni, izithelo nemifino, izimpahla ezomile, izilwane zasolwandle nokunye ukudla, futhi kusetshenziswa kabanzi ekulondolozweni nasekufakweni kweminye imikhiqizo, njengemikhiqizo yezokwelapha, izingxenye ze-elekthronikhi nokunye.
Kodwa-ke, ukupakishwa kwe-vacuum akuyona into engenangqondo.
Kunezizathu ezimbalwa okungenzeka ukuthi kungani ukudla kusengawohloka ngokushesha ngemva kokufakwa kwe-vacuum:
Ukupakisha okungaphelele: Uma umoya osephaketheni ungasuswa ngokuphelele lapho ukudla kufakwe i-vacuum-packed, kuzosala inani elithile lomoya-mpilo, okungase kukhuthaze ukukhula kwama-microorganisms kanye ne-oxidation yokudla, okuholela ekuwohlokeni kokudla.
Ukulimala kokupakisha: Izikhwama zokupakisha ze-vacuum zingalimala kancane ngesikhathi sokugcinwa noma ukuthuthwa, okuzovumela umoya ukuthi ungene, ucekele phansi indawo ye-vacuum, futhi andise ingozi yokonakaliswa kokudla.
Ukungcoliswa kwamagciwane: Uma ukudla kungcoliswe amagciwane ngaphambi kokufakwa, ngisho nasendaweni engenalutho, amanye ama-anaerobic microorganisms asengakhula, okuholela ekoneni kokudla.
Ukuwohloka kwamakhemikhali: Okunye ukudla kungase kube ukuwohloka kwamakhemikhali okungabangelwa ama-microorganisms, njengokuphuma kwe-oxidation yamafutha, ngisho nangaphansi kwezimo ze-hypoxic.
Izinga lokushisa elingafanele lesitoreji: Izinga lokushisa linomthelela obalulekile eshalofini lempilo yokudla. Uma ukudla okufakwe i-vacuum kungagcinwa ezingeni lokushisa elifanele, njengemikhiqizo eqandisiwe noma eqandisiwe ayifakwanga esiqandisini ngendlela efanele, izosheshisa ukonakala kokudla.
Ukudla ngokwako kunesikhathi esifushane seshelufu: noma ngabe okunye ukudla kufakwe i-vacuum-packed, ngenxa yezimpawu zakho, kungahlala kusha isikhathi esifushane, ikakhulukazi lokho kudla okonakalayo.
Ukuze kunwetshwe impilo yeshalofu yokudla okupakishwe nge-vacuum, amaphuzu alandelayo kufanele enziwe:
Okokuqala, khetha izinto zokupakisha ezifanele. Kubalulekile ukukhetha izinto zokupakisha ze-vacuum ezifanele, okufanele zibe nezakhiwo ezinhle zokuvimbela ukuvimbela ukungena komoya-mpilo namanzi. Ngesikhathi esifanayo, unake ukushuba emaphaketheni, vacuum emaphaketheni akuyona mkhulu, emaphaketheni obukhulu kakhulu ku-vacuum kungase kubonakale isimo sokubeka uphawu ezimbi, ezithinta umphumela wokugcina.
Ukuhlanza nokwelashwa kusengaphambili. Ngaphambi kokupakisha, qinisekisa ukuthi ingaphezulu lokudla lomile futhi lihlanzekile. Uma kunesidingo, phatha ukudla kusengaphambili ukuze ugweme ukupakishwa ngoketshezi oluningi noma amafutha, ukuze ungaphazamisi i-vacuum.
Okwesithathu, i-vacuum degree kanye nokuvala uphawu. Sebenzisa umshini wokupakisha we-vacuum ochwepheshe ukuze ukhiphe umoya omningi ngangokunokwenzeka ephaketheni, bese ulivala ngokuqinile. Lokhu kusiza ukunweba isikhathi seshelufu sokudla futhi kunciphisa amathuba okukhula kwamagciwane. Ngasikhathi sinye, amapharamitha afanelekile kufanele akhethwe ngokuya ngezinto ezibonakalayo, ukujiya kanye nohlobo lwemikhiqizo yokupakisha yokupakisha i-vacuum ukugwema izinkinga ezinjengokuvalwa uphawu okuxekethile, ukuvuza komoya, nezikhwama eziphukile.
Ukulawula izinga lokushisa: ukudla okufakwe ku-vacuum kufanele kugcinwe ezingeni lokushisa elifanele, ngokuvamile kufakwe efrijini noma kuqandiswe, kuye ngohlobo lokudla kanye nempilo yeshalofu elindelekile.
Gwema ukulimala komshini. Ngesikhathi sokupakisha, ukuthutha kanye nokugcinwa, ukunakekelwa kufanele kuthathwe ukuze kugwenywe ukulimala komshini ekudleni, ngoba izingxenye ezilimele kulula ukuqothulwa ngamabhaktheriya.
