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 chakudya zomwe zidapangidwa kale, zam'chitini ndikusindikizidwa mu zitini zachitsulo, mabotolo agalasi, mapulasitiki ndi mbiya zina, kenako chosawilitsidwa kuti akwaniritse kusabereka kwamalonda ndipo amatha kusungidwa kutentha kwa nthawi yayitali.Kutseketsa kwa chakudya cham'chitini kumagawidwa m'njira ziwiri: chakudya chochepa cha asidi chokhala ndi pH mtengo woposa 4.6 chiyenera kusamalidwa 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 kuwerengera okhwima, mutatha kutsekereza pang'onopang'ono ndi kuzizira pa kutentha ndi nthawi zosiyanasiyana, mpweya wina umapangidwa, ndi tizilombo toyambitsa matenda ndi mabakiteriya owononga mu chitini amaphedwa mwa njira yotseketsa, ndi zakudya ndi kukoma kwa chakudya chokha. 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 owononga tizilombo toyambitsa matenda ndi tizilombo toyambitsa matenda, 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 yayitali kwa chakudya cham'chitini kumatha kuzindikirika pambuyo pokonzekera, kuyika kumalo, kusindikiza ndi kutseketsa, kotero chakudya cham'chitini sichiyenera kuwonjezera zotetezera ndipo zikhoza kudyedwa bwinobwino.
