Ngakhale njira zachikhalidwe zopangira tiyi zimasunga kukoma koyambirira kwa masamba a tiyi, njirayi ndi yovuta kwambiri ndipo imavutika kukwaniritsa zosowa za moyo wachangu. Chifukwa chake, tiyi wachangu watchuka kwambiri pamsika ngati chakumwa chosavuta kugwiritsa ntchito. Ukadaulo wowumitsa tiyi wa vacuum, womwe umatha kusunga mtundu woyambirira, fungo, ndi zakudya za zinthu zopangira mpaka pamlingo waukulu, wakhala chisankho chabwino kwambiri chopangira ufa wa tiyi wachangu wapamwamba kwambiri.
Njira yowumitsa ndi vacuum imafuna kuziziritsa zinthuzo kenako kuchotsa chinyezi mwa kuziyika mu nthunzi molunjika pansi pa vacuum. Njirayi, ikachitika kutentha kochepa, imapewa kuwonongeka kwa kutentha kwa zinthu zomwe zimakhudzidwa ndi kutentha, kuonetsetsa kuti ntchito ya zamoyo ndi zinthu za physicochemical zimasungidwa. Poyerekeza ndi kuumitsa kwachikhalidwe, kuumitsa ndi vacuum kumapanga zinthu zomwe zili pafupi ndi chilengedwe chawo, zomwe zimakhala ndi mphamvu zosungunulira bwino komanso zobwezeretsa madzi m'thupi.
Ubwino wa Kuumitsa Tiyi Popanda Kuzizira (Mwachidule ndi "ZONSE ZIWIRI"):
1. Kusunga Kukoma kwa Tiyi: Njira yochepetsera kutentha imaletsa kutayika kwa mankhwala onunkhira osasunthika, kuonetsetsa kuti ufa wa tiyi womwe umakhalapo nthawi yomweyo umasunga fungo lake labwino la tiyi.
2. Chitetezo cha Zakudya: Tiyi ili ndi mankhwala ambiri a polyphenolic, amino acid, ndi zinthu zina zothandiza. Kuumitsa mufiriji kumapangitsa kuti madzi asatayike bwino popanda kuwononga zinthuzi, zomwe zimasunga thanzi la tiyi.
3. Makhalidwe Abwino a Kumva: Ufa wa tiyi wouma mufiriji umakhala ndi tinthu tating'onoting'ono tofanana, tomwe timakhala ndi mtundu wachilengedwe, ndipo umapewa kufiira komwe kumachitika nthawi zambiri mukauma. Kapangidwe kake ka mabowo kamalola kusungunuka nthawi yomweyo popanda zotsalira, zomwe zimapangitsa kuti ogula azisangalala nazo.
4. Moyo Wowonjezera wa Shelf: Tiyi wouma nthawi yomweyo wouma mufiriji uli ndi chinyezi chochepa, umaletsa kuyamwa kwa chinyezi ndi kukula kwa nkhungu, ndipo umasunga bwino nthawi yayitali yosungidwa kutentha kwa chipinda.
Kukonza Ma Parameters a Freeze-Drying a Tiyi Yomwe Imangochitika:
Kuti mupeze ufa wa tiyi wa nthawi yomweyo wabwino kwambiri, magawo ofunikira a njira yogwiritsira ntchito ayenera kupangidwa mosamala ndikukonzedwa bwino:
Mikhalidwe Yochotsera: Kutentha (monga 100°C), nthawi (monga mphindi 30), ndi nthawi yotulutsa tiyi zimakhudza kwambiri ubwino wa mowa wa tiyi. Kafukufuku akusonyeza kuti kutulutsa tiyi bwino kumawonjezera zosakaniza zogwira ntchito monga ma polyphenols a tiyi.
Kutentha Kozizira Kwambiri: Kawirikawiri imayikidwa pafupifupi -40°C kuti iwonetsetse kuti makristalo a ayezi apangidwa bwino, ndikuyika maziko a sublimation yogwira mtima.
Kuwongolera Kuchuluka kwa KuumaKutentha pang'onopang'ono kumasunga kukhazikika kwa kapangidwe ka chinthucho. Kutentha mwachangu kapena pang'onopang'ono kungawononge ubwino wake.
Kutentha kwa Msampha Wozizira & Mlingo wa Vacuum: Chotchinga chozizira pansi pa -75°C ndi vacuum ≤5 Pa chimathandiza kuti madzi asanyowe bwino komanso kuchepetsa nthawi youma.
Maganizo "ONSE AWIRI":
Kuumitsa tiyi mu vacuum sikuti kumangowonjezera ubwino wa tiyi nthawi yomweyo komanso kumawonjezera ntchito zake—monga kuigwiritsa ntchito mu zakudya zogwiritsidwa ntchito popanga zokhwasula-khwasula, zakumwa, komanso zinthu zosamalira khungu. Ukadaulo uwu umathandizanso mabizinesi ang'onoang'ono ndi apakatikati kuti alowe mumsika wa tiyi nthawi yomweyo, zomwe zimapangitsa kuti mafakitale azisintha komanso kupanga zatsopano.
