"Gaba iri rakagadzirwa kwerinopfuura gore, nei richiri mukati mesherufu? Richiri kudyiwa here? Pane zvakawanda zvinochengetedza mariri? Izvi zvinogona kuchengetedzwa here?" Vatengi vazhinji vanozove nehanya nekuchengetedza kwenguva refu. Mibvunzo yakafanana inomuka kubva muzvokudya zvomumagaba, asi chaizvoizvo zvokudya zvomumagaba zvinogona kuchengetedzwa kwenguva refu kupfurikidza nokusabereka kwezvokutengeserana.
Chikafu chemumagaba chinoreva midziyo yechikafu yakabikwa kare, yakaiswa mumagaba uye yakavharwa mumagaba esimbi, mabhodhoro egirazi, mapurasitiki nezvimwe midziyo, uye yobva yaitwa sterility kuti iwane sterility yekutengeserana uye inogona kuchengetwa pamhepo tembiricha kwenguva yakareba. Kuvharirwa kwechikafu chemumagaba kwakakamurwa kuva nzira mbiri: chikafu chepasi-asidhi chine pH kukosha chinodarika 4.6 chinofanira kucheneswa nekupisa kwepamusoro (kunenge 118°C-121°C), uye chikafu chine acidic chine pH iri pasi pe4.6, semichero yemumagaba, inofanira kucheneswa (95°C-100°C).
Vamwe vanhu vanogona zvakare kubvunza kana chikafu chiri muchikafu chakaparadzwa zvakare mushure mekunge chikafu chemumagaba chaitwa sterilized nekupisa kwakanyanya? Chikafu chemumagaba hachisina zvinovaka muviri here? Izvi zvinotanga nezvinonzi commercial sterility.
Zvinoenderana ne "Canned Food Indasitiri Handbook" yakaburitswa neChina Light Indasitiri Press, kushambadzira kwekutengesa kunoreva chokwadi chekuti chikafu chakasiyana mushure mekuisa chisimbiso nekuisa chisimbiso kune akasiyana pH kukosha uye mabhakitiriya akasiyana anotakurwa ega. Mushure mekuyedzwa kwesainzi uye kuverenga kwakasimba, mushure mekuita sterilization zvine mwero uye kutonhora pakudziya kwakasiyana uye nguva, imwe vacuum inoumbwa, uye mabhakitiriya epathogenic uye mabhakitiriya anoparadza ari mugaba anouraiwa kuburikidza nekuita sterilization, uye chikafu uye kunaka kwechikafu pachacho kunochengetedzwa kusvika pamwero mukuru. Iine kukosha kwekutengeserana panguva yehupenyu hwesherufu yezvokudya. Naizvozvo, kugadzirwa kwechikafu chemumagaba hakuurayi mabhakitiriya ese, asi kunongotarisa mabhakitiriya epathogenic uye mabhakitiriya anoparadza, kuchengetedza zvinovaka muviri, uye kugadzirwa kwechikafu kwakawanda inzira yekubika, ichiita kuti ruvara rwavo, kunhuhwirira uye kuravira zvive nani. Yakakora, inovaka muviri uye inonaka.
Naizvozvo, kuchengetedzwa kwenguva refu kwechikafu chemumagaba kunogona kuitika mushure mekutanga, kugadzika, kuiswa chisimbiso uye sterilization, saka chikafu chemumagaba hachidi kuwedzera zvinodzivirira uye chinogona kudyiwa zvakachengeteka.
