“Le can’t isinesikhathi esingaphezu konyaka ikhiqizwa, kungani isekhona eshalofini?Ingabe isadliwa?Ingabe kukhona ama-preservatives amaningi kuwo?Ingabe lokhu kungaphephile?”Abathengi abaningi bazokhathazeka ngesitoreji sesikhathi eside.Imibuzo efanayo iphakama kusukela ekudleni okusemathinini, kodwa empeleni ukudla okusemathinini kungagcinwa isikhathi eside ngenxa yobunyumba bezentengiselwano.
Ukudla okusemathinini kubhekisela ezintweni ezingavuthiwe zokudla eziye zafakwa ngaphambili, zafakwa ethini futhi zavalwa emathinini ensimbi, amabhodlela engilazi, amapulasitiki nezinye iziqukathi, zase zifakwa inzalo ukuze kuzuzwe inzalo yokuhweba futhi zingagcinwa endaweni yokushisa yasekamelweni isikhathi eside.Ukufakwa inzalo kokudla okusemathinini kuhlukaniswe ngezindlela ezimbili: ukudla okune-asidi ephansi enenani le-pH elingaphezu kuka-4.6 kufanele kubulawe amagciwane ngokushisa okuphezulu (okungaba ngu-118°C-121°C), nokudla okune-asidi okune-pH engaphansi kuka-4.6, njenge izithelo ezisemathinini, kufanele zifakwe ku-pasteurized (95°C-100°C).
Abanye abantu bangase futhi babuze ukuthi imisoco esekudleni nayo iyashabalala ngemva kokuba ukudla okusemathinini kufakwe inzalo ngenxa yokushisa okuphezulu?Ingabe ukudla okusemathinini akusenawo umsoco?Lokhu kuqala ngokuthi inyumba yokuhweba.
Ngokusho kwe- "Canned Food Industry Handbook" enyatheliswa yi-China Light Industry Press, ubunyumba bezentengiselwano bubhekisela eqinisweni lokuthi ukudla okuhlukene ngemva kokufakwa emathinini nokubekwa uphawu kunamanani e-pH ahlukene kanye namagciwane ahlukene aphathwa ngokwawo.Ngemuva kokuhlolwa kwesayensi nokubala okuqinile, ngemuva kokuvala inzalo okusesilinganisweni kanye nokupholisa emazingeni okushisa ahlukene nangezikhathi, kwakhiwa indawo ethile yokungena, futhi amabhaktheriya e-pathogenic nama-spoilage bacterium ku-can abulawa ngenqubo yokuvala inzalo, kanye nemisoco kanye nokunambitheka kokudla ngokwako. zigcinwa ngezinga elikhulu kakhulu.Inenani lezentengiselwano ngesikhathi sokudla kokudla.Ngakho-ke, inqubo yokuvala inzalo yokudla okusemathinini ayiwabulali wonke amabhaktheriya, kodwa ihlose kuphela amabhaktheriya e-pathogenic kanye nama-bacterium spoilage, ukulondoloza izakhi, futhi inqubo yokuvala inzalo yokudla okuningi nayo iyinqubo yokupheka, okwenza umbala wabo, iphunga nokunambitha kangcono.Okushubile, okunomsoco futhi okumnandi kakhulu.
Ngakho-ke, ukulondolozwa kwesikhathi eside kokudla okusemathinini kungabonakala ngemuva kokwelashwa, ukucwiliswa, ukuvala nokuvala inzalo, ngakho-ke ukudla okusemathinini akudingi ukwengeza ama-preservatives futhi kungadliwa ngokuphepha.
