Zakudya zam'chitini zimatha kusungidwa kwa nthawi yayitali popanda zoteteza

"Iyi yakhala ikupangidwa kwa nthawi yopitilira chaka, chifukwa chiyani ikadali mkati mwa alumali? Kodi zikadali zodyedwa? Kodi pali zoteteza zambiri mmenemo? Kodi izi zitha kukhala zotetezeka?" Ogula ambiri adzakhudzidwa ndi kusungidwa kwa nthawi yayitali. Mafunso ofananawo amabwera kuchokera ku chakudya cham'chitini, koma kwenikweni chakudya cham'zitini chikhoza kusungidwa kwa nthawi yaitali kupyolera mu kusabereka kwamalonda.

Chakudya cham'chitini chimatanthawuza zinthu zopangira zakudya zomwe zidapangidwa kale, zam'chitini ndikumata zitini zachitsulo, mabotolo agalasi, mapulasitiki ndi mbiya zina, kenako chosawilitsidwa kuti akwaniritse sterility yamalonda ndipo amatha kusungidwa kutentha kwa nthawi yayitali. Kusakaniza kwa chakudya cham'chitini kumagawidwa m'njira ziwiri: chakudya chochepa cha asidi chokhala ndi pH mtengo woposa 4.6 chiyenera kusakanizidwa ndi kutentha kwakukulu (pafupifupi 118 ° C-121 ° C), ndi chakudya cha acidic chokhala ndi pH pansi pa 4.6, monga zipatso zamzitini, ziyenera kukhala ndi pasteurized (95 ° C-100 ° C).

Anthu ena atha kukayikiranso ngati zakudya zomwe zili m'zakudya zimawonongekanso chakudya cham'chitini chikawotchedwa ndi kutentha kwambiri? Kodi chakudya cham'zitini sichikhalanso ndi thanzi? Izi zimayamba ndi zomwe zili sterility yamalonda.

Malinga ndi "Canned Food Industry Handbook" lofalitsidwa ndi China Light Industry Press, sterility yamalonda imatanthawuza kuti zakudya zosiyanasiyana pambuyo pozika ndikusindikiza zimakhala ndi pH yosiyana ndi mabakiteriya osiyanasiyana omwe amanyamula okha. Pambuyo kuyezetsa kwasayansi ndi kuwerengetsa okhwima, pambuyo zolimbitsa yolera yotseketsa ndi kuzirala pa kutentha ndi nthawi zosiyanasiyana, vacuum wina aumbike, ndi tizilombo tizilombo ndi mabakiteriya spoilage mu chitini amaphedwa mwa njira yolera yotseketsa, ndi zakudya ndi kukoma kwa chakudya palokha. amasungidwa kumlingo waukulu kwambiri. Lili ndi phindu pazamalonda pa nthawi ya alumali ya chakudya. Choncho, njira yotseketsa chakudya cham'chitini sichipha mabakiteriya onse, koma imangoyang'ana mabakiteriya a tizilombo toyambitsa matenda ndi mabakiteriya owononga, kusunga zakudya, komanso njira yochepetsera zakudya zambiri ndi njira yophika, kupanga mtundu wawo, fungo ndi kukoma bwino. Zonenepa, zopatsa thanzi komanso zokoma kwambiri.

Choncho, kusunga kwa nthawi yaitali kwa chakudya cham'chitini kumatha kuzindikirika pambuyo pokonzekera, kuyika kumalo, kusindikiza ndi kutseketsa, kotero chakudya cham'chitini sichiyenera kuwonjezera zotetezera ndipo zikhoza kudyedwa bwinobwino.
