N'chifukwa chiyani madzi a zipatso amafunikira pasteurized?

Madzi a zipatso okhala ndi zipatso monga zopangira kudzera m'njira zakuthupi monga kukanikiza, centrifugation, m'zigawo ndi zinthu zina zamadzimadzi, zosinthidwa kukhala zakumwa zopangidwa ndi zinthu.Madzi a zipatso amasunga michere yambiri mu chipatso, monga mavitamini, mchere, shuga, ndi pectin muzakudya zamafuta.
The kuteteza nyengo ya madzi a zipatso ndi yochepa kwambiri, makamaka chifukwa cha chikoka cha tizilombo, chifukwa kagayidwe kachakudya ntchito tizilombo mu madzi a zipatso ndi wokangalika, choncho makamaka kofunika kusankha yoyenera yolera yotseketsa luso kuteteza kuwonongeka kwa zipatso zakumwa zakumwa. .Pankhani yotseketsa zakumwa zamadzimadzi, ndikofunikira kupha mabakiteriya owopsa ndi mabakiteriya owononga mumadzimadzi, kuwongolera kuchuluka kwa madera kumakwaniritsa miyezo yadziko, komanso kuwononga ma enzymes mumadzimadzi kuti asungidwe. nthawi mu malo enieni;china ndi kuteteza zakudya zikuchokera ndi kukoma kwa madzi mmene ndingathere mu ndondomeko yolera yotseketsa.
Mu njira ya madzi a zipatso yotentha yotseketsa, pali pasteurization (njira yotsika kutentha kwa nthawi yayitali), njira yochepetsera kutentha kwanthawi yochepa komanso njira yophatikizira yotentha kwambiri.Kutentha kwakukulu kwa nthawi yochepa yoletsa njira yochepetsera matenthedwe ndikwabwinoko, koma kutentha nthawi zambiri kumabweretsa zotsatira zoyipa pamtundu wa madzi a zipatso, monga kusintha kwa mtundu, kukoma, kutaya zakudya, ndi zina zambiri.
Ndipo luso la pasteurization, posintha mapuloteni ndi ma enzyme a maselo a tizilombo tating'onoting'ono, motero kulepheretsa ntchito ya michere, kupha mabakiteriya ambiri owononga ndi tizilombo toyambitsa matenda mu madzi a zipatso, pamene kumverera ndi zakudya zamtengo wapatali za chakudya sizidzakhudzidwa.Iwo sangakhoze kukwaniritsa cholinga cha yolera yotseketsa ndi passivation wa michere pa kutentha m`munsi, komanso kuthandiza kukhalabe zipatso mtundu, fungo, kukoma, zakudya ndi kutsitsimuka, kukwaniritsa zofunika ogula kulimbikitsa "zachilengedwe ndi thanzi" chakudya.Chifukwa chake, kuphunzira ukadaulo wa pasteurization ndikofunikira kwambiri pachitetezo, mtundu ndi zakudya zamadzi a zipatso zatsopano.
Ndikoyenera kudziwa kuti pasteurization ndi zamzitini kapena madzi a m'mabotolo, ngati ndi madzi a m'mabotolo a galasi, ayenera kuganizira za vuto la kutentha ndi kuzizira, kuteteza kusiyana kwa kutentha ndi kwakukulu kwambiri ndipo kumabweretsa kuphulika kwa botolo, kotero makina athu a pasteurization amagawidwa kukhala. zigawo zinayi, zomwe ndi preheating, sterilization, pre-kuzizira ndi kuziziritsa, koma dzina lonse ndi madzi pasteurization makina.
