Umgaqo wobugcisa weengxowa zokupakisha i-vacuum, ngaphezu kokuthintela i-microorganisms ekukhuleni nasekuphindaphindeni ngaphakathi, isetyenziselwa ukukhusela i-oxidation yokutya.
Iingxowa zokupakisha zevacuum zohlulwe zibe ziingxowa zokufunxa ezikhenkcezisiweyo kunye neengxowa zokupheka. Iingxowa zokupakisha ezifakwe emkhenkceni zisetyenziswa ngokubanzi, njenge: iinkozo ze-walnut, inyama yenkomo, i-mutton, iibhola zerayisi, i-dumplings njalo njalo. Sinokuzifumana kuyo yonke indawo kwiivenkile ezinkulu. Ebomini, ukutya okuninzi okukhenkcezayo kukhetha iingxowa zokupakisha i-vacuum, eyona njongo iphambili kukugcina umgangatho kunye nokutsha.
Iingxowa zokupakisha zevacuum ezikhenkcezisiweyo zineempawu zokumelana nempembelelo entle, kubandakanya ukomelela kunye nobude ngexesha lekhefu, ezibonisa amandla emveliso ukumelana nokuzolula ngexesha lokusetyenziswa. Ukuba le nto ayifanelekanga, ngexesha lokusetyenziswa kweengxowa zokupakisha ukutya zivame ukuphuka kunye nomonakalo. Emva kokuba ukutya okufriziwe kufakwe i-vacuum-packed, kufuneka kuthuthwe, kulayishwe kwaye kukhutshwe, kubekwe kwi-shelf, njl. Ngexesha lezi nkqubo, isikhwama sokufunxa ukutya esikhenkcezisiweyo sonakaliswa lula yimikhosi yangaphandle. Ukuba ukuchasana kwempembelelo yesikhwama sokupakisha se-frozen vacuum sihlwempuzekile, kulula kakhulu ukuphula isikhwama kwaye uvule isikhwama. , ayichaphazeli nje kuphela ukubonakala kweemveliso ezipakishweyo, kodwa kwakhona ayikwazi ukudlala indima yokupakisha ngokwayo.
Ukongeza, ikwabandakanya izikhombisi zokuthintelwa kwegesi ezifana nokungena kwerhasi; izalathi zokuxhathisa ioyile, ukumelana nobushushu, ukumelana nokubanda, ukuxhathisa okuphakathi; ukutywinwa kwengxowa kunye nokunyanzeliswa kwe-peelling, i-bag pressure resistance resistance and drop resistance kunye nezinye izibonakaliso, ezi zikhombisi zibonisa isikhwama sokupakisha ukutya. Ukuthembeka kokhuseleko lokupakisha lwangaphakathi.
I-ductility elungileyo, ukuxhathisa kweenyembezi, akukho lula ukuphuka
Iingxowa ezintathu zokutywinwa kobushushu zifanelekile kuninzi koomatshini bokutywina ukushisa
Zonke iimveliso zivavanywa ngokunyanzeliswayo kunye nelebhu ye-QA ekumgangatho ophezulu kwaye ufumane isiqinisekiso selungelo elilodwa lomenzi wechiza.
