Ibhegi yokupakisha ivacuumItekhnoloji yavela kwiminyaka yama-40s, ukusukela oko ifilimu yeplastiki ye-50s isetyenziswe ngempumelelo kwipakethe yempahla, itekhnoloji yokupakisha i-vacuum iphuhliswe ngokukhawuleza.Inqanaba lokupakishwa ukuya kumlinganiselo othile libonakalisa inqanaba lenzululwazi nethekhinoloji kunye nokutyeba kwelizwe.Uphando lweteknoloji yokupakisha ye-vacuum yaseTshayina kunye nokusetyenziswa kusekutsha.
Okokuqala, ngo-1962, ifilimu ecetywayo ye-Ordal engabonakaliyo inokuthintela ukukhula kwee-microorganisms ze-pathogenic, ukupakisha inyama entsha kunokwandisa ubomi bayo beshelufu.
Okwesibini, Baltzer ukuba vacuum ukupakishwa iingxowa inyama entsha ngaphezu aerobically zipakishwe fresh inyama kwishelufu ubomi ixesha elide ngenxa yezi zizathu zilandelayo: (1) inani lilonke microorganisms kwiimeko anaerobic landa ngokucothayo;(2) ukubola kunye nokunciphisa i-mucus;(3) emva kokugcinwa, inani lokugqibela le-microorganisms kwi-vacuum package lingaphantsi kwe-aerobic packaging.Oku kubonisa ukuba ifilimu vacuum engenakunyakaziswa yokupakisha inyama entsha, xa ioksijini ekuyo iguqulwa ibe yikharbon diokside, ifilimu engabonakaliyo ingavala i-oksijini yangaphandle ukuba iphinde ingene kwiphakheji, ngoko ke isikhwama sokupakisha se-vacuum sinokwandisa ubomi beshelufu yenyama entsha.
Okwesithathu, ngo-1970, uPierson kunye nezinye izindululo zokupakishwa kwevacuum ukudala ukhetho lweentlobo ze-microbial kunye namanqanaba "ecosystem".Ngo-1974 inkampani yeSCOPA yaqala yafaka iMAP (ModifiedAtmospherePackage, yivacuum kuqala, emva koko ngo-1974, iSCOPA yaqala yafaka iMAP (Modified AtmospherePackage, luhlobo lokupakisha oluqale lucocwe luze luzaliswe ngepesenti ethile yomxube werhasi) ukupakisha. iimveliso zenyama.
Okwesine, uPesis et al.(1986) wacebisa ukubaiingxowa zokupakisha zevacuumyeyona ndlela ilungileyo yokugcina umgangatho kunye nobunzima bokugcinwa kweziqhamo zepersimmon.Oku kubonisa ukuba uphuhliso kunye nokuthandwa kogcino kunye nokugcinwa kweteknoloji iya kuxabiswa ngakumbi ngabavelisi, abaqhubi kunye nabathengi.Enye inxalenye yezixhobo ezifunekayo ukupakishwa kwe-vacuum yi-container yokupakisha, izitya zokupakisha zeentlobo ezininzi, kukho iplastiki, iplastiki kunye nephepha, i-aluminium foil kunye nezinye izinto ezidibeneyo ezenziwe nge-compound, iibhotile zeglasi, izitya zetsimbi kunye neplastiki enzima, njl. ukhetho lwezikhongozeli zokupakisha kufuneka lusekelwe kubume bokutya okufakwe kwi-vacuum, njengokutya okunkonkxiweyo kufakwe kwiibhotile zeglasi okanye iitoti zetsimbi, ezifana neyeza zaseTshayina kunye ne-aluminium foil okanye iplastiki, njl. izixhobo zokupakisha iingxowa zokupakisha, kodwa eyona nto ixhaphakileyo yifilimu yeplastiki.
Ngokufika kokudityaniswa koqoqosho lwehlabathi, ishishini leplastiki laseChina liphezulu ukuba "liyeyona nkokeli ikhuphisanayo neguquguqukayo kwishishini lokupakisha", njengenjongo, ukuqhubeka nokuphuhlisa, ukwenza izinto ezintsha, kwaye sijonge phambili ekusebenzisaneni nesininzi soogxa ekhaya nakwamanye amazwe ukudala. ingomso elingcono.
