“Le tini iveliswe ixesha elingaphezu konyaka, kutheni isesekwixesha lokuphelelwa kwayo? Ingaba isatyiwa? Ngaba kukho izinto ezininzi zokugcina ukutya kuyo? Ngaba le tini ikhuselekile?” Abathengi abaninzi baya kuba nexhala malunga nokugcinwa kwayo ixesha elide. Imibuzo efanayo iphakama kukutya okusemathinini, kodwa eneneni ukutya okusemathinini kunokugcinwa ixesha elide ngenxa yokungabi nazintsholongwane kurhwebo.
Ukutya okusemathinini kubhekisa kwizinto zokutya ezilungisiweyo, ezisemathinini zaza zavalwa kwiitini zentsimbi, iibhotile zeglasi, iiplastiki kunye nezinye izikhongozeli, zaze zacocwa ukuze kufumaneke ukungcola okuthengiweyo kwaye zingagcinwa kubushushu begumbi ixesha elide. Ukucoca ukutya okusemathinini kwahlulwe ngeendlela ezimbini: ukutya okune-asidi ephantsi okunexabiso le-pH elingaphezulu kwe-4.6 kufuneka kucocwe ngobushushu obuphezulu (malunga ne-118°C-121°C), kunye nokutya okune-asidi okunexabiso le-pH elingaphantsi kwe-4.6, njengeziqhamo ezisemathinini, kufuneka kucocwe (95°C-100°C).
Abanye abantu basenokubuza ukuba ingaba izondlo ezikukutya ziyatshatyalaliswa na emva kokuba ukutya okusemathinini kucocwe ngobushushu obuphezulu? Ngaba ukutya okusemathinini akusenazo izondlo? Oku kuqala ngokuthi yintoni i-sterility yorhwebo.
Ngokutsho kwe-"Canned Food Industry Handbook" epapashwe yiChina Light Industry Press, ukungazali kwezorhwebo kubhekisa kwinto yokuba ukutya okwahlukileyo emva kokugalelwa kunye nokutywinwa kunemilinganiselo ye-pH eyahlukileyo kunye neebhaktheriya ezahlukeneyo ezithwalwa zodwa. Emva kovavanyo lwesayensi kunye nokubala okungqongqo, emva kokucoca okuphakathi kunye nokuphola kumaqondo obushushu ahlukeneyo kunye namaxesha ahlukeneyo, kwenziwa i-vacuum ethile, kwaye iibhaktheriya ezibangela izifo kunye neebhaktheriya ezibangela ukubola kwi-can ziyabulawa ngenkqubo yokucoca, kwaye izondlo kunye nencasa yokutya ngokwayo zigcinwa kakhulu. Inexabiso lorhwebo ngexesha lokutya okugciniweyo. Ke ngoko, inkqubo yokucoca ukutya okusemathinini ayibulali zonke iibhaktheriya, kodwa ijolise kuphela kwiibhaktheriya ezibangela ukubola kunye neebhaktheriya ezibangela ukubola, igcina izondlo, kwaye inkqubo yokucoca ukutya okuninzi nayo yinkqubo yokupheka, yenza umbala wazo, ivumba kunye nencasa ibe ngcono. Ityebile, inesondlo kwaye imnandi ngakumbi.
Ngoko ke, ukugcinwa kwexesha elide kokutya okusemathinini kunokufezekiswa emva kokunyangwa kwangaphambili, ukugalelwa emathinini, ukutywinwa kunye nokubulawa kweentsholongwane, ngoko ke ukutya okusemathinini akufuneki kongeze izinto zokugcina ukutya kwaye kunokutyiwa ngokukhuselekileyo.
