"Leli thini selikhiqizwe isikhathi esingaphezu konyaka, kungani lisasebenza eshalofini? Ingabe lisadliwa? Ingabe kunezilondolozi eziningi kulo? Ingabe leli thini liphephile?" Abathengi abaningi bazokhathazeka ngokugcinwa kwesikhathi eside. Imibuzo efanayo iphakama ekudleni okusemathinini, kodwa empeleni ukudla okusemathinini kungagcinwa isikhathi eside ngenxa yokungabi namagciwane kwezentengiselwano.
Ukudla okusemathinini kubhekisela ezintweni zokudla ezilungisiwe, ezisemathinini futhi zavalwa emathinini ensimbi, emabhodleleni engilazi, epulasitiki nakwezinye izitsha, bese zihlanzwa ukuze kufezwe ukungabi namagciwane kwezentengiselwano futhi kungagcinwa ekamelweni lokushisa isikhathi eside. Ukuhlanza ukudla okusemathinini kuhlukaniswe ngezindlela ezimbili: ukudla okune-asidi ephansi okunenani le-pH elingaphezu kuka-4.6 kufanele kuhlanzwe ngokushisa okuphezulu (cishe u-118°C-121°C), kanye nokudla okune-asidi okunenani le-pH elingaphansi kuka-4.6, njengezithelo ezisemathinini, kufanele kuhlanzwe (95°C-100°C).
Abanye abantu bangase babuze nokuthi izakhamzimba ezikukudla nazo ziyabhujiswa yini ngemva kokuba ukudla okusemathinini kuhlanjululwe ngokushisa okuphezulu? Ingabe ukudla okusemathinini akusasenazo izakhamzimba? Lokhu kuqala ngokuthi yini ukungahlanjululi kwezentengiselwano.
Ngokusho kwe-“Canned Food Industry Handbook” enyatheliswa yi-China Light Industry Press, ukungazali kwezentengiselwano kubhekisela eqinisweni lokuthi ukudla okuhlukene ngemva kokukufaka emathinini nokuvala kune-pH ehlukene kanye namabhaktheriya ahlukene athwalwa yiwo ngokwawo. Ngemva kokuhlolwa kwesayensi nokubala okuqinile, ngemva kokuhlanza okulinganiselwe kanye nokupholisa emazingeni okushisa ahlukene kanye nezikhathi, kwakheka i-vacuum ethile, bese amabhaktheriya abangela izifo kanye namabhaktheriya abangela izifo emathinini abulawa ngenqubo yokuhlanza, futhi izakhamzimba kanye nokunambitheka kokudla ngokwako kugcinwa ngezinga elikhulu kakhulu. Inenani lokuhweba ngesikhathi sokudla okuseshalofini. Ngakho-ke, inqubo yokuhlanza ukudla okusemathinini ayibulali wonke amabhaktheriya, kodwa ihlose kuphela amabhaktheriya abangela izifo kanye namabhaktheriya abangela izifo, igcina izakhamzimba, futhi inqubo yokuhlanza ukudla okuningi nayo iyinqubo yokupheka, yenza umbala wawo, iphunga kanye nokunambitheka kube ngcono. Kukhulu, kunempilo futhi kumnandi kakhulu.
Ngakho-ke, ukulondolozwa kwesikhathi eside kokudla okusemathinini kungatholakala ngemva kokwelashwa kwangaphambi kwesikhathi, ukukufaka emathinini, ukuvala kanye nokubulala amagciwane, ngakho-ke ukudla okusemathinini akudingeki kufake izithasiselo futhi kungadliwa ngokuphephile.
