Kodi mumadziwa bwanji za kuzizira?

Kuzizira ndi njira yosungira chakudya, mankhwala, ndi zinthu zina pochepetsa kutentha kwake mpaka kuzizira.Ukadaulo uwu ukhoza kukulitsa moyo wa alumali wazinthu, monga kutentha kochepa kumachepetsa kwambiri kukula kwa tizilombo komanso kuthamanga kwazomwe zimachitika.Zotsatirazi ndi zambiri zokhudza kuzizira:

Mfundo Zoyambira

1. Kutentha kosiyanasiyana: Kuzizira kumaphatikizapo kutsitsa kutentha kwa chinthu kufika -18 ° C kapena kutsika.Pakutentha uku, madzi ambiri amapanga ice makhiristo, tizilombo tating'onoting'ono timayima, ndipo kagayidwe kachakudya kachakudya kumachepetsanso kwambiri.
2. Kutembenuka kwa madzi: Panthawi yozizira, madzi omwe amapangidwawo amasandulika kukhala makristasi a ayezi, omwe amathandiza kuti mabakiteriya asakule komanso kuti mankhwala asamachitike.Komabe, kupanga makristasi oundana kumatha kusokoneza kapangidwe ka ma cell, chomwe ndi chimodzi mwazifukwa zomwe zakudya zoziziritsa kukhosi zimatha kusintha mawonekedwe atatha kusungunuka.

Kuzizira kwaukadaulo

1. Kuzizira kofulumira: Kuzizira kofulumira ndi njira yomwe imagwiritsidwa ntchito kwambiri yomwe imachepetsa kukula kwa madzi oundana omwe amapangidwa mkati mwa chakudya mwa kuchepetsa kutentha kwa chakudya, zomwe zimathandiza kuteteza mapangidwe ndi mawonekedwe a chakudya.Izi nthawi zambiri zimatheka popanga malonda pogwiritsa ntchito zipangizo zafriji.
2. Kuzizira kozizira kwambiri: Muzinthu zina zapadera (monga madera ena a kafukufuku wa sayansi ndi kusunga chakudya chapamwamba), kuzizira kozizira kwambiri kungagwiritsidwe ntchito, ndipo kutentha kumatha kuchepetsedwa kufika -80 ° C kapena kutsika kuti mukwaniritse. nthawi yayitali kwambiri yosungira.
3. Kusunga mufiriji: Chakudya chowumitsidwa chiyenera kusungidwa mufiriji yoyenera, monga mufiriji wa m’nyumba kapena kusungirako kuzizira kwa malonda, kuonetsetsa kuti chakudyacho chikusungidwa m’malo ozizira bwino.

malo ofunsira

1. Makampani a chakudya: M'makampani azakudya, kuzizira ndi njira yodziwika bwino yosungira, yoyenera zakudya zosiyanasiyana monga nyama, nsomba zam'madzi, zakudya zophika, mkaka, zipatso ndi ndiwo zamasamba.
2. Zaumoyo: Mankhwala ena ndi zitsanzo zamoyo (monga magazi, maselo, ndi zina zotero) zimafuna cryopreservation kuti zikhalebe zokhazikika komanso zogwira mtima.
3. Kafukufuku wa sayansi: Mu kafukufuku wa sayansi, teknoloji yozizira imagwiritsidwa ntchito kusunga zitsanzo zosiyanasiyana zamoyo ndi zopangira mankhwala pofuna kufufuza ndi kusanthula kwa nthawi yaitali.

zinthu zofunika kuziganizira

1. Kuyika bwino: Kuyika bwino ndikofunikira kuti zisawonongeke ndi chisanu ndi kuumitsa chakudya.Kugwiritsa ntchito zinthu zosungiramo zinthu zosunga chinyezi komanso zomata bwino kumatha kuteteza chakudya.
2. Pewani kuzizira kobwerezabwereza: Kuzizira kobwerezabwereza kungathe kuwononga kapangidwe ndi kadyedwe ka chakudya, ndipo kuyenera kupewedwa momwe zingathere.
3. Kusungunula motetezeka: Njira yosungunula ndiyofunikanso kwambiri, ndipo iyenera kusungunuka pang'onopang'ono mufiriji, kapena kusungunuka mwamsanga pogwiritsa ntchito microwave ndi madzi ozizira kuchepetsa mwayi wa bakiteriya.

Kuzizira ndi njira yabwino kwambiri yotetezera yomwe imachepetsa kwambiri zochitika za tizilombo toyambitsa matenda ndi kusintha kwa mankhwala, kukulitsa moyo wa alumali wa chakudya ndi zinthu zina zovuta.Kuzizira koyenera ndi njira zosungunulira kungapangitse kuti chakudya chikhale chopatsa thanzi komanso chomveka bwino.
