Nayitrogeni wamadzimadzi ndi wosavuta kuzizira.Chifukwa cha mawonekedwe ake apadera, nayitrogeni wamadzimadzi walandira chidwi ndi kuzindikirika pang'onopang'ono, ndipo wakhala akugwiritsidwa ntchito mochulukirachulukira pakuweta nyama, chithandizo chamankhwala, mafakitale azakudya, komanso magawo ofufuza a kutentha kochepa., zamagetsi, zitsulo, zakuthambo, kupanga makina ndi zina zowonjezera ndi chitukuko.
Nayitrogeni wamadzimadzi ndiye cryogen yomwe imagwiritsidwa ntchito kwambiri pakuchita opaleshoni.Ndi imodzi mwamafiriji abwino kwambiri omwe apezeka mpaka pano.Ikhoza kubayidwa mu chipangizo chachipatala cha cryogenic, monga scalpel, ndipo imatha kugwira ntchito iliyonse.Cryotherapy ndi njira yochiritsira yomwe kutentha kochepa kumagwiritsidwa ntchito kuwononga minofu ya matenda.Chifukwa cha kusintha kwakukulu kwa kutentha, makhiristo amapangidwa mkati ndi kunja kwa minofu, zomwe zimapangitsa kuti maselo awonongeke ndi kuchepa, zomwe zimapangitsa kusintha kwa electrolyte, ndi zina zotero. Chifukwa cha hypoxia, maselo amafa.
Pakati pa njira zambiri zotetezera, cryopreservation ndiyomwe imagwiritsidwa ntchito kwambiri ndipo zotsatira zake zimakhala zofunikira kwambiri.Monga imodzi mwa njira zochepetsera kuzizira, kuzizira kwa nayitrogeni wamadzimadzi kumagwiritsidwa ntchito kale ndi mabizinesi opangira zakudya.Chifukwa chimatha kuzindikira kuzizira kofulumira kwambiri pakuzizira kocheperako komanso kuzizira kwambiri, kumathandizanso kuti chakudya chachisanu chizizizira pang'ono, kotero kuti chakudyacho chikhoza kuchira kwambiri chitatha kusungunuka.Kumalo atsopano komanso zakudya zoyambira, zakudya zoziziritsa bwino zakhala zikuyenda bwino kwambiri, motero zawonetsa mphamvu zapadera m'makampani oziziritsa mwachangu.
Kutentha kwapang'onopang'ono kwa chakudya ndi njira yatsopano yopangira chakudya yomwe yapangidwa m'zaka zaposachedwa.Ukadaulowu ndiwoyenera makamaka pokonza zakudya zokhala ndi mtengo wonunkhira kwambiri, mafuta ochulukirapo, shuga wambiri komanso zinthu zambiri za colloidal.Kugwiritsa ntchito nayitrogeni madzi otsika kutentha pulverization, fupa, khungu, nyama, chipolopolo, etc. ya zipangizo akhoza pulverized pa nthawi imodzi, kuti particles wa mankhwala yomalizidwa bwino ndi kuteteza zake zothandiza zakudya.Mwachitsanzo, ku Japan, nyanja zam'madzi, chitin, masamba, zokometsera, ndi zina zotere, zomwe zasungidwa mumadzi a nayitrogeni, zimayikidwa mu pulverizer kuti zipunthidwe, kuti tinthu tating'ono tating'ono tating'ono tating'ono tating'ono ting'onoting'ono ting'onoting'ono ta 100um. kapena zocheperapo, ndipo zakudya zopatsa thanzi zimasungidwa.
Kuphatikiza apo, kugwiritsa ntchito nayitrogeni wamadzimadzi potsitsa kutentha pang'ono kungathenso kupukuta zinthu zomwe zimakhala zovuta kupukuta ndi kutentha kwa chipinda, zinthu zomwe sizimva kutentha, ndi zinthu zomwe zimawonongeka mosavuta ndikuwola zikatenthedwa.Kuphatikiza apo, nayitrogeni wamadzimadzi amatha kuphwanya zinthu zopangira chakudya zomwe zimakhala zovuta kuziphwanya kutentha kwa chipinda, monga nyama yamafuta ndi masamba okhala ndi madzi ambiri, ndipo zimatha kupanga zakudya zatsopano zomwe sizinawonekerepo.
Chifukwa cha firiji ya nayitrogeni wamadzimadzi, ochapira dzira, zokometsera zamadzimadzi, ndi msuzi wa soya zitha kukonzedwa kukhala zakudya zoziziritsa kukhosi zosasunthika komanso zothira zomwe zakonzeka kugwiritsidwa ntchito komanso zosavuta kukonza.
