Posachedwapa, ogula ena adakambirana za momwe angagulirevacuum phukusichakudya.Zikumveka kuti pakadali pano, pali njira zitatu zosungira chakudya chatsopano: kudzaza nayitrogeni, kupukuta ndi kuwonjezera zoteteza.Kuteteza vacuum ndikosavuta, kwachilengedwe komanso kwathanzi.
Vacuum kulongedza kumatanthauza kutithumba la vacuum packagingamamaliza mawonekedwe omaliza a zomwe zasungidwa mu makina opangira vacuum.Mmodzi mwa maulalo ofunikira ndikutulutsa mpweya ndi deoxidization, zomwe ndikuletsa chakudya ku mildew ndi kuwola.Ntchito ina yofunika ya vacuum deoxidization ndi kuteteza chakudya okosijeni.Mwachitsanzo, zakudya zamafuta zimakhala ndi unsaturated fatty acids wambiri, zomwe zimakhala zosavuta kusintha mtundu ndi kukoma ndi okosijeni.Kusindikiza vacuum kumatha kulekanitsa mpweya ku okosijeni, ndikusunga mtundu, kakomedwe ndi kadyedwe kachakudya.
Ndikoyenera kuzindikira zimenezovacuum phukusipalokha ilibe mphamvu yotseketsa.Pofuna kupezerapo mwayi paubwino waukadaulo wonyamula vacuum, m'pofunikanso kuchita kutseketsa kofunikira pambuyo pomaliza kuyika vacuum, monga kutsekereza kutentha kwambiri, kutseketsa kwa radiation, etc. Chakudya chilichonse chowonongeka chomwe chiyenera kusungidwa mufiriji. iyenera kukhala yosungidwa mufiriji kapena kuzizira pambuyo polongedza vacuum.Kupaka vacuum si njira ina m'malo mwa firiji kapena kusunga mufiriji.Kuphatikiza apo, nthawi yosungiramo zingalowe m'zakudya zosungidwa pa kutentha kosiyanasiyana ndi yosiyana.
Momwe mungasankhire otetezekavacuum phukusichakudya?
Choyamba, onani thumba lotupa
Kaya kukulitsa chikwama ndi njira yodziwikiratu komanso yabwino kwa ogula kuweruza ngatichakudya vacuum phukusizawonongeka.Malinga ndi nzeru wamba ya sayansi, nthawi zonse, kuthamanga kwa mpweya m'thumba lazakudya kuyenera kukhala kofanana ndi dziko lakunja kapena kucheperako poyerekeza ndi dziko lakunja mutatsuka.Ngati thumba likukulitsidwa, zikutanthauza kuti kuthamanga kwa mpweya m'thumba ndipamwamba kuposa dziko lakunja, zomwe zikutanthauza kuti mpweya watsopano umapangidwa mu thumba losindikizidwa.Mipweya iyi ndi metabolites yomwe imapangidwa pambuyo pa kuchulukitsa kwa tizilombo tating'onoting'ono, chifukwa kachulukidwe kakang'ono ka metabolites sikukwanira kukulitsa thumba.Zambiri mwa mabakiteriya kapena nkhungu (mabakiteriya a lactic acid, yisiti, aerogenes, polymyxobacillus, Aspergillus, etc.) zomwe zingayambitse kuwonongeka kwa chakudya zidzatulutsa mpweya wambiri mu ndondomeko yowonongeka kwa mapuloteni ndi shuga mu chakudya, monga carbon dioxide, hydrogen sulfide, ammonia, alkane, etc., omwe "amawomba" thumba loyika mu baluni.Pa njira yolera yotseketsa chakudya musanayambe kulongedza, tizilombo toyambitsa matenda ndi masamba sizinaphedwe kwathunthu.Pambuyo polongedza, tizilombo toyambitsa matenda timachulukana kwambiri, zomwe zimayambitsa ziphuphu.Mwachibadwa, vuto la bulging matumba ma CD kumachitika.
Chachiwiri, kununkhiza
Pogulavacuum phukusichakudya, musatenge fungo la chakudya monga muyezo chiweruzo.Ngati kukoma kwa chakudya kutayikira m'paketi, zikutanthauza kutivacuum phukusipalokha sikhalanso vacuum, ndipo pali mpweya kutayikira.Izi zikutanthauza kuti mabakiteriya amathanso "kuyenda" momasuka.
Chachitatu, zizindikiro zoyendera
Kuti mupeze phukusi lazakudya, yang'anani kaye ngati chilolezo chake chopangira, SC code, wopanga ndi mndandanda wazinthu zonse zatha.Ziphaso zimenezi zili ngati “ma ID makadi” a chakudya.Kuseri kwa ziphaso kuli “moyo wakale ndi wamakono” wa chakudya, kumene iwo anachokera ndi kumene iwo akhala.
Chachinayi, tcherani khutu ku alumali moyo wa chakudya
Chakudya chomwe chili pafupi ndi nthawi ya alumali sichivulaza, koma mtundu wake ndi zakudya zake zidzachepa.Pambuyo pavacuum phukusichakudya chimatsegulidwa, chiyenera kudyedwa mwamsanga ndipo sichiyenera kusungidwa mufiriji.Mukamagula "gulani mmodzi apeze chakudya chaulere", samalani za tsiku lopanga ndi nthawi ya alumali ya katundu womangidwa.
