Ogula zipatso zowuma{{0}zouma amasamala kwambiri za kadyedwe koyenera komanso kukoma kwachilengedwe. Zotentha-zakudya za sitiroberi zowumitsidwa ndi mpweya pamsika zili ndi zolakwika zoonekeratu: kutentha kwambiri kumawola anthocyanin, zipatso zimasanduka zofiira; kuchepa kwa vitamini C kumaposa 60%; fungo lapadera la sitiroberi limasinthasintha mochuluka, ndipo kukoma kwake kumakhala kovuta komanso kouma. Zogulitsa zoterezi zimatha kugulitsidwa pamtengo wotsika komanso kusowa mpikisano wamsika wakunja.
Vacuum freeze-kuumitsa kumazindikiridwa ngati njira yabwino koposa-yosungirako makina a zipatso. Makina athu owumitsira sitiroberi amakwaniritsa zonse-zotsekera zotentha-zatsopano za mawonekedwe a mabulosi. Malo oundana-ozizira kwambiri amatha kufika madigiri -55 ° ~-60 digirii, ndikuundana mwachangu madzi aulere omwe ali m'kati mwa sitiroberi kukhala makristalo olimba a ayezi. Pansi pa malo otsekemera kwambiri, makhiristo oundana amakhazikika mu nthunzi yamadzi popanda kusungunuka m'madzi amadzimadzi, kotero kuti sitiroberi zamkati sizingagwe ndikupunduka.
Poyerekeza ndi kuyanika kwa mpweya wotentha, deta yosungiramo michere ya kuzizira-mastrawberries owuma ndiwodziwika: kuchuluka kwa vitamini C kumasungidwa kuposa 90%, kutayika kwa anthocyanin ndi kosakwana 8%, ndipo fungo lachilengedwe la zipatso limasungidwa. Chogulitsidwacho ndi chowoneka bwino komanso chopepuka, liwiro lobwezeretsa madzi m'thupi ndi lachangu, litha kugwiritsidwa ntchito popanga zokhwasula-khwasula, zopaka yogati, zowotcha ndi zina zambiri-zogwiritsa ntchito.
Tinakonza kayendedwe ka mpweya wamkati ndi mpweya wabwino wa bin yowumitsira kuti tithetse vuto la kusakwanira bwino kwa sitiroberi wamkulu-. Miyezo yambiri-yomwe imasunga kutentha kwa mathireyi onse mkati mwa digirii ±1 , sitiroberi aliyense amalandila kutenthetsa kosasinthasintha, kupeŵa kutayika pang'ono-kuuma kapena kutayika kwa michere yambiri chifukwa chakuuma kwambiri-.
Dongosolo lanzeru lowongolera kutentha limatha kusintha kuchuluka kwa kutentha munthawi yeniyeni molingana ndi madzi omwe ali mu sitiroberi nthawi zosiyanasiyana zakucha. Kwa sitiroberi osakhwima okhala ndi madzi ambiri, onjezerani nthawi yochepera-yotentha kwambiri; Kuti mukhale ndi sitiroberi okoma okhwima, konzani ndondomekoyi moyenera kuti musunge mphamvu ndikuonetsetsa kuti -zotsekera zatsopano.
Kwa mabizinesi okonza zipatso omwe amayang'ana kwambiri-kuzizira kwambiri kutumiza kunja{1}}zipatso zouma, kuzizira pang'ono-kuzizira kozizira kwambiri-ukadaulo wowumitsa ndiwo mwayi waukulu wopikisana nawo.
