Isikhwama sokupakisha se-vacuumubuchwepheshe baqala ngeminyaka yama-40s, njengoba ifilimu yepulasitiki yama-50s yasetshenziswa ngempumelelo ekufakweni kwempahla, ubuchwepheshe besikhwama sokupakisha se-vacuum buye bathuthukiswa ngokushesha.Izinga lokupakisha ngokwezinga elithile libonisa izinga lesayensi nobuchwepheshe kanye nokuceba kwezwe.Ucwaningo lobuchwepheshe besikhwama se-vacuum base-China kanye nokusetshenziswa kuseyinsakavukela.
Okokuqala, ngo-1962, ifilimu ehlongozwayo ye-Ordal engenakunyakaziswa ingavimbela ukukhula kwama-microorganisms e-pathogenic, ukupakisha inyama entsha kunganweba impilo yayo yeshalofu.
Okwesibili, Baltzer ukuthi izikhwama vacuum emaphaketheni yenyama fresh kuka aerobically zapakishwa fresh inyama eshalofini ukuphila isikhathi eside ngenxa yezizathu ezilandelayo: (1) inani eliphelele microorganisms ezimweni anaerobic inyuka kancane;(2) ukubola nokunciphisa amafinyila;(3) ngemva kokugcinwa, inani lokugcina lama-microorganisms kuphakheji ye-vacuum lingaphansi kokufakwa kwe-aerobic.Lokhu kubonisa ukuthi i-vacuum yefilimu engenakunyakaziswa epakisha inyama entsha, lapho umoya-mpilo kuyo uguqulelwa ku-carbon dioxide, ifilimu engangenisi ingavimba umoya-mpilo wangaphandle ukuze ungene kabusha ephaketheni, ngakho isikhwama sokupakisha se-vacuum singanweba impilo yeshalofu yenyama entsha.
Okwesithathu, ngo-1970, u-Pierson kanye nokunye okuhlongozwayo kokufakwa kwe-vacuum ukudala ukukhethwa kwezinhlobo ze-microbial kanye namazinga "we-ecosystem".Ngo-1974 inkampani ye-SCOPA yaqala ukusebenzisa i-MAP (ModifiedAtmospherePackage, iyivacuum kuqala, kwase kuthi Ngo-1974, i-SCOPA yaqala yasebenzisa i-MAP (Modified AtmospherePackage, okuwuhlobo lokupakisha oluvalwa kuqala bese lugcwaliswa ngephesenti elithile lengxube yegesi) ukupakisha. imikhiqizo yenyama.
Okwesine, uPesis et al.(1986) waphakamisa ukuthiizikhwama zokupakisha ze-vacuumkuyindlela engcono kakhulu yokugcina ikhwalithi nobulukhuni bokugcinwa kwezithelo ze-persimmon.Lokhu kubonisa ukuthi ukuthuthukiswa nokuthandwa kokugcina nokugcinwa kobuchwepheshe kuya ngokuya kubaluleka ngabakhiqizi, abaqhubi kanye nabathengi.Enye ingxenye yemishini edingekayo ekufakweni kwe-vacuum yisitsha sokupakisha, iziqukathi zokupakisha zezinhlobo eziningi, kukhona ipulasitiki, ipulasitiki nephepha, ucwecwe lwe-aluminium nezinye izinto eziyinhlanganisela ezakhiwe ngenhlanganisela, amabhodlela engilazi, iziqukathi zensimbi nepulasitiki eqinile, njll. ukukhethwa kweziqukathi zokupakisha kufanele kusekelwe esimweni sokudla okugcwele i-vacuum, njengokudla okusemathinini kusetshenziselwa amabhodlela engilazi noma amathini ensimbi, njengemithi ye-herbal yamaShayina ene-aluminium foil noma ipulasitiki, njll. Nakuba kunezinhlobo eziningi ze izinto zesitsha sezikhwama zokupakisha ze-vacuum, kodwa okuvame kakhulu ifilimu yepulasitiki.
Ngokufika kokuhlanganiswa komnotho wembulunga yonke, imboni yepulasitiki ephezulu yaseChina ukuze "ibe umholi wemboni yokupakisha oncintisana kakhulu", njengomgomo, iqhubeke nokuthuthukisa, ukusungula izinto ezintsha, futhi ibheke ngabomvu ukusebenzisana neningi lozakwethu ekhaya nakwamanye amazwe ukudala ikusasa elingcono.
