"Chirongo ichi chave chichigadzirwa kwenguva inopfuura gore, sei chichiri kushanda kwenguva refu? Chichiri kudyiwa here? Pane zvinhu zvakawanda zvinochengetedza here? Chirongo ichi chakachengeteka here?" Vatengi vazhinji vachanetseka nezvekuchengetwa kwenguva refu. Mibvunzo yakafanana inomuka kubva muzvikafu zvemumagaba, asi kutaura chokwadi chikafu chemumagaba chinogona kuchengetedzwa kwenguva yakareba kuburikidza nekusabatwa nehutachiona hwekutengesa.
Chikafu chakabikwa mugaba chinoreva zvinhu zvekudya zvakambogadzirwa kare, zvakabikwa mugaba uye zvakavharirwa mumagaba esimbi, mabhodhoro egirazi, mapurasitiki nezvimwe zvirongo, uye zvozopiswa kuti zvisabereke uye zvinogona kuchengetwa patembiricha yemukamuri kwenguva yakareba. Kupiswa kwezvikafu zvakabikwa mugaba kwakakamurwa kuita nzira mbiri: chikafu chine acid shoma chine pH inopfuura 4.6 chinofanira kuchenesa nekupisa kwakanyanya (inenge 118°C-121°C), uye chikafu chine acid ine pH isingasviki 4.6, senge michero yakabikwa mugaba, chinofanira kuparadzwa (95°C-100°C).
Vamwe vanhu vanogonawo kubvunza kuti zvinovaka muviri zviri muchikafu zvinoparadzwawo here mushure mekunge chikafu chiri mugaba chabatwa nehutachiona nekuda kwekupisa kwakanyanya? Chikafu chiri mugaba hachina hutano here? Izvi zvinotanga nekusabatwa nehutachiona hwekutengesa.
Sekureva kwe "Canned Food Industry Handbook" yakaburitswa neChina Light Industry Press, kusabereka kwezvekudya kunoreva kuti zvekudya zvakasiyana mushure mekubikwa nekuvhara zvine pH dzakasiyana uye mabhakitiriya akasiyana anotakurwa ega. Mushure mekuyedzwa kwesainzi uye kuverenga kwakasimba, mushure mekubikwa zvine mwero uye kutonhodza pakupisa kwakasiyana nenguva, vacuum inoumbwa, uye mabhakitiriya anokonzera zvirwere uye mabhakitiriya anoora ari mugaba anourayiwa kuburikidza nekubikwa, uye zvinovaka muviri nekuravira kwechikafu pachacho zvinochengetwa zvakanyanya. Zvine kukosha kwekutengeserana panguva yehupenyu hwechikafu. Naizvozvo, maitiro ekubvisa kusabereka kwezvekudya zvemugaba haauraye mabhakitiriya ese, asi anongotarisa mabhakitiriya anokonzera zvirwere uye mabhakitiriya anoora, kuchengetedza zvinovaka muviri, uye maitiro ekubvisa kusabereka kwezvekudya zvakawanda inzira yekubika, zvichiita kuti ruvara rwavo, kunhuhwirira uye kuravira zvive nani. Gobvu, rine hutano uye rinonaka.
Saka, kuchengetedza kwenguva refu kwechikafu chemumagaba kunogona kuitika mushure mekurapwa, kuchengetwa mumagaba, kuvharwa uye kucheneswa, saka chikafu chemumagaba hachidi kuwedzerwa mishonga yekuchengetedza uye chinogona kudyiwa zvakachengeteka.
