Inqubo yokuvala inzalo edingekayo ekukhiqizweni kokudla okuhlukene nayo ihlukile. Abakhiqizi bokudla badinga ukuthenga izimbiza zokuvala inzalo ukuze bandise impilo yeshelufu yokudla. Badinga ukuvala inzalo noma ukuvala inzalo ukudla ekushiseni okuphezulu isikhathi esifushane, okungagcini nje ngokubulala amagciwane angaba khona ekudleni, kodwa futhi kugcina izingxenye ezibalulekile zokudla okunomsoco kanye nombala, iphunga, kanye nephunga elimnandi lokudla ukuthi kungonakali.
Imikhiqizo yenyama kumele iqandiswe ku -40 degrees Celsius ngemva kokufakwa kwevacuum ngomshini wokupakisha ivacuum, bese igcinwa ku -18 degrees Celsius cishe izinyanga ezintathu. Uma izivimbelakuvunda zengezwa emikhiqizweni yokudla okuphekiwe, ngokuvamile zingagcinwa izinsuku eziyi-15 kusetshenziswa i-vacuum packaging. Uma zigcinwe emazingeni okushisa aphansi, zingagcinwa izinsuku ezingama-30. Kodwa-ke, uma ama-preservatives angeziwe, ngisho noma i-vacuum packaging isetshenziswa futhi igcinwe emazingeni okushisa aphansi, ingagcinwa izinsuku ezintathu kuphela. Ngemuva kwezinsuku ezintathu, kokubili ukunambitheka nokunambitha kuzoba kubi kakhulu. Eminye imikhiqizo ingaba nesikhathi sokugcina esiyizinsuku ezingama-45 noma ezingu-60 ezibhalwe ezikhwameni zayo zokupakisha, kodwa lokho empeleni okokungena ezitolo ezinkulu. Ngenxa yemithetho ezitolo ezinkulu, uma impilo yeshalofu idlula ingxenye eyodwa kwezintathu yenani eliphelele, izimpahla azikwazi ukutholwa, uma impilo yeshalofu idlula ingxenye, kufanele isuswe, futhi uma impilo yeshalofu idlula izingxenye ezimbili kwezintathu, kufanele wabuya.
Uma ukudla kungavalwanga ngemva kokufakwa kwe-vacuum, ngeke kunwebe isikhathi seshelufu sokudla okuphekiwe. Ngenxa yomswakama ophezulu kanye nokudla okunothile kokudla okuphekiwe, kulula kakhulu ukukhula kwamagciwane. Kwesinye isikhathi, ukupakishwa kwe-vacuum kusheshisa izinga lokubola lokudla okuthile. Kodwa-ke, uma izinyathelo zokuvala inzalo zithathwa ngemva kokufakwa kwe-vacuum, impilo yeshalofu iyahluka kusukela ezinsukwini eziyi-15 kuye kwezingama-360 kuye ngezidingo ezihlukene zokuvala inzalo. Isibonelo, imikhiqizo yobisi ingagcinwa ngokuphephile ekamelweni lokushisa phakathi kwezinsuku ezingu-15 ngemva kokupakishwa kwe-vacuum kanye nokuvalwa kwe-microwave, kuyilapho imikhiqizo yenkukhu ebhemayo ingagcinwa izinyanga ezingu-6-12 noma ngisho nangaphezulu ngemva kokupakishwa kwe-vacuum kanye nokuvalwa kwezinga lokushisa eliphezulu. Ngemuva kokusebenzisa umshini wokupakisha we-vacuum wokudla wokufaka i-vacuum, amagciwane asazophindaphindeka ngaphakathi komkhiqizo, ngakho-ke ukuvala inzalo kufanele kwenziwe. Kunezinhlobo eziningana zokuvala inzalo, kanti eminye imifino ephekiwe ayidingi izinga lokushisa elingaphezu kuka-100 degrees Celsius. Ungakhetha umugqa we-pasteurization. Uma izinga lokushisa lingaphezu kuka-100 degrees Celsius, ungakhetha igedlela lokuvala inzalo elinengcindezi ephezulu yokuvala inzalo.
