Chakudya chowumitsidwa mufiriji, chofupikitsidwa ngati chakudya cha FD, chimapangidwa pogwiritsa ntchito ukadaulo wa vacuum freeze-drying. Zogulitsazi zimatha kusungidwa kutentha kwa firiji kwa zaka zoposa zisanu popanda zotetezera, ndipo ndizopepuka, zomwe zimapangitsa kuti zikhale zosavuta kuzinyamula ndi kuzinyamula.
KugwiritsaChowumitsa Muziziritsa, umisiri wowumitsa muumi wa vacuum umenewu umatetezera bwino mtundu, kakomedwe, ndi kadyedwe kake, kusunga maonekedwe ake, fungo lake, kakomedwe kake, ndi kapangidwe kake, kwinaku akusungabe zakudya zofunika monga mavitamini ndi mapulotini. Asanayambe kudya, kukonzekera pang'ono kumapangitsa kuti apangidwenso kukhala chakudya chatsopano mkati mwa mphindi zochepa. Komanso, zakudya zowumitsidwa m’firiji sizifunika kuziyika m’firiji ndipo zimatha kusungidwa, kunyamulidwa, ndi kugulitsidwa pa kutentha kwa firiji zitasindikizidwa m’matumba.
1. Njira: Zakudya Zowuma Zozizira vs. Zakudya zopanda madzi
Kuchepa madzi m'thupi:
Kutaya madzi m'thupi, komwe kumadziwikanso kuti kuyanika kwamafuta, ndi njira yowumitsa yomwe imagwiritsa ntchito zonyamulira zamafuta ndi chinyezi. Nthawi zambiri, mpweya wotentha umagwira ntchito ngati chonyamulira cha kutentha ndi chinyezi. Mpweya wotentha umatenthedwa ndiyeno umagwiritsidwa ntchito pazakudya, zomwe zimapangitsa kuti chinyezi chisasunthike ndikutengedwa ndi mpweya.
Kutaya madzi m'thupi kumagwira ntchito mwa kusamutsa kutentha kuchokera kunja ndi chinyezi kuchokera mkati, chomwe chili ndi malire ake. Ngati kutentha kuli kwakukulu, kungapangitse kuti kunja kuchepetse, kuchepetsa kuyanika, pamene kutentha kwambiri kungayambitse kusagwira ntchito. Kuchuluka kwa chinyezi chamkati kumapangitsa kuti makoma a cell aphwanyike, zomwe zimapangitsa kuti michere iwonongeke.
Kuyanika-Kuzizira:
Kuumitsa kuzizira kumaphatikizapo kuchepetsa chinyezi, pamene kutaya madzi m'thupi kumadalira mpweya. Mu kuunika kowuma, chinyezi chimasintha kuchokera ku cholimba kupita ku gasi, kusunga mawonekedwe a chakudya. Mosiyana ndi zimenezi, kutaya madzi m'thupi kumasintha chinyezi kuchokera kumadzi kupita ku gasi.
Pakadali pano, kuyanika kwa vacuum ndi njira yabwino kwambiri yomwe ilipo. Pansi pa kutentha kochepa, kutsika kwapakati, mawonekedwe a thupi la chakudya amakhalabe osakhudzidwa, kuteteza kuchepa chifukwa cha kulowetsedwa kwa chinyezi. Njirayi imawonjezeranso gawo la sublimation, zomwe zimapangitsa kuti kuyanika bwino kwambiri.
2. Zotsatira: Chakudya Chowuma Chozizira vs Chakudya Chopanda madzi
Shelf Life:
Kuchuluka kwa chinyezi kumakhudza mwachindunji moyo wa alumali. Zakudya zopanda madzi monga zipatso zouma, masamba, ndi ufa zimakhala ndi alumali moyo wa zaka 15-20; uchi, shuga, mchere, tirigu wolimba, ndi oats zimatha kupitilira zaka 30. Mosiyana ndi izi, zipatso ndi ndiwo zamasamba zowumitsidwa mufiriji zimatha zaka 25-30.
Zazakudya:
Malinga ndi kafukufuku wochokera ku mabungwe azaumoyo ku US, kuyanika kozizira kumasunga mavitamini ndi mchere wambiri. Komabe, zakudya zowuma mufiriji zingakhale zopanda mavitamini, monga vitamini C, amene amawonongeka msanga. Kutaya madzi m'thupi sikusintha fiber kapena ayironi, koma kungayambitse kuwonongeka kwa mavitamini ndi minerals, zomwe zimapangitsa kuti zakudya zopanda madzi zikhale zopanda thanzi kusiyana ndi zakudya zowuma. Kutayika kwa michere kumatha kuchitika chifukwa cha mavitamini A ndi C, niacin, riboflavin, ndi thiamine panthawi yakusowa madzi m'thupi.
Chinyezi:
Cholinga chachikulu cha kusunga chakudya ndikuchotsa chinyezi, kuteteza kuwonongeka ndi kukula kwa nkhungu. Kutaya madzi m'thupi kumachotsa 90-95% ya chinyezi, pamene kuunika kozizira kumatha kuthetsa 98-99%. Kutaya madzi m'thupi m'nyumba nthawi zambiri kumasiya pafupifupi 10% chinyezi, pomwe njira zochepetsera madzi m'thupi zimatha kukhala ndi moyo wautali.
Maonekedwe ndi Kapangidwe:
Kusiyanitsa kwakukulu pakati pa zakudya zopanda madzi ndi zowuma ndi mawonekedwe awo. Zakudya zopanda madzi m'thupi zimakhala zofewa komanso zolimba, pomwe zakudya zowumitsidwa zimafewa zikangolowa mkamwa. Zakudya zowuma mufiriji ndizopepuka kwambiri kuposa zomwe zilibe madzi.
Kuphika:
Zakudya zopanda madzi zimafunika kuziphika musanadye ndipo nthawi zambiri zimafunikira zokometsera. Izi zikutanthauza kuthera nthawi yophika zinthuzo m'madzi otentha musanadye. Kukonzekera zakudya zopanda madzi m'thupi kumatha kutenga pakati pa mphindi 15 mpaka maola anayi. Mosiyana ndi zimenezi, zakudya zowumitsidwa mufiriji zimangofuna madzi otentha; ingowonjezerani madzi otentha kapena ozizira ndikudikirira mphindi 5 kuti mudye.
Pomaliza, zikuwonekeratu kuti ndi zakudya ziti zomwe zitha kukhala bwino pamsika wamasiku ano. Zakudya zobiriwira komanso zathanzi zikuchulukirachulukira zomwe anthu amatsata.
Ngati mukufuna wathuChakudya Makina Owumitsa Owumitsakapena muli ndi mafunso, chonde omasukaLumikizanani nafe. Monga akatswiri opanga makina owumitsira amaundana, timapereka mitundu yosiyanasiyana, kuphatikiza apanyumba, ma labotale, oyendetsa ndege, ndi mitundu yopangira. Kaya mukufuna zida zogwiritsira ntchito kunyumba kapena zida zazikulu zamafakitale, titha kukupatsirani zinthu ndi ntchito zapamwamba kwambiri.
