Wazi kangakanani malunga nomkhenkce?

Ukukhenkceza yindlela yokugcina ukutya, iziyobisi nezinye izinto ngokuthoba ubushushu bube ngaphantsi kweqondo lomkhenkce.Le teknoloji inokwandisa ngokufanelekileyo ubomi beshelufu yeemveliso, njengoko amaqondo obushushu aphantsi anciphisa kakhulu ukukhula kwee-microorganisms kunye nesantya sokuphendula kwamachiza.Oku kulandelayo lulwazi oluneenkcukacha malunga nomkhenkce:

Imigaqo esisiseko

1. Uluhlu lobushushu: Ukukhenkceza kubandakanya ukuthoba ubushushu bemveliso ukuya kwi -18 ° C okanye ngaphantsi.Kweli qondo lobushushu, uninzi lwamanzi lubumba iikristale zomkhenkce, umsebenzi we-microbial uyayeka, kwaye inkqubo yemetabolism yokutya nayo iyancipha kakhulu.
2. Ukuguqulwa kwamanzi: Ngethuba lenkqubo yokukhenkceza, amanzi kwimveliso aguqulwa abe yi-crystals ye-ice, enceda ukuthintela ukukhula kwebhaktheriya kunye neekhemikhali ezibangelwa ukwenzeka.Nangona kunjalo, ukubunjwa kweekristale zomkhenkce kunokuphazamisa isakhiwo seselula, esinye sezizathu zokuba ukutya okufriziwe kunokuba namava okutshintsha ukuthungwa emva kokunyibilika.

Itekhnoloji yokukhenkceza

1. Umkhenkce okhawulezayo: Ukukhenkceza okukhawulezayo yindlela esetyenziswa ngokuqhelekileyo enciphisa ubungakanani beekristale zomkhenkce ezenziwe ngaphakathi kokutya ngokuhlisa ngokukhawuleza ubushushu bokutya, kunceda ukukhusela ubume kunye nokwakheka kokutya.Oku kudla ngokufezekiswa kwimveliso yorhwebo usebenzisa izixhobo ezisebenzayo zefriji.
2. Iqondo lomkhenkce eliphantsi kakhulu: Kwizicelo ezithile (ezifana nemimandla ethile yophando lwezenzululwazi kunye nokugcinwa kokutya okuphezulu), iqondo lomkhenkce eliphantsi kakhulu linokusetyenziswa, kwaye iqondo lobushushu linokwehliswa ukuya kutsho -80 ° C okanye ngaphantsi ukuze kuphunyezwe. ixesha elide kakhulu lokugcina.
3. Ukugcinwa emkhenkceni: Ukutya okunomkhenkce kufuneka kugcinwe kwisixhobo sokukhenkcisa esifanelekileyo, njengesikhenkcisi sasekhaya okanye indawo ebandayo ethengiswayo, ukuqinisekisa ukuba ukutya kugcinwa kubushushu obukhuselekileyo.

indawo yesicelo

1. Ishishini lokutya: Kwishishini lokutya, ukukhenkceza kuyindlela eqhelekileyo yokugcinwa, ilungele ukutya okuhlukahlukeneyo okufana nenyama, intlanzi yaselwandle, ukutya okuphekiweyo, iimveliso zobisi, iziqhamo kunye nemifuno.
2. Ukhathalelo lwempilo: Amachiza athile kunye neesampuli zebhayoloji (ezifana negazi, iiseli, njl.) zifuna i-cryopreservation ukuze zigcine uzinzo kunye nokusebenza kwazo.
3. Uphando lwezeNzululwazi: Kuphando lwezenzululwazi, itekhnoloji yokukhenkcisa isetyenziselwa ukugcina iisampulu ezahlukeneyo zebhayoloji kunye neekhemikhali zokwenziwa kophando kunye nohlalutyo.

imiba efuna ingqalelo

1. Ukupakishwa ngendlela efanelekileyo: Ukupakishwa ngendlela efanelekileyo kubalulekile ukuze kuthintelwe iqabaka nokomisa kokutya.Ukusebenzisa izinto zokupakisha ezinobungqina bokufuma kwaye zitywinwe kakuhle kunokukhusela ukutya.
2. Ziphephe imijikelo yokunyibilikisa ephinda-phindayo yokukhenkceza: Imijikelo ephindaphindwayo yokunyibilika komkhenkce inokonakalisa ukwakheka kunye nesondlo sokutya, kwaye kufuneka iphetshwe kangangoko kunokwenzeka.
3. Ukunyibilika okukhuselekileyo: Inkqubo yokunyibilika nayo ibaluleke kakhulu, kwaye kufuneka inyibilike kancinane kwisikhenkcisi, okanye inyibilikiswe ngokukhawuleza kusetyenziswa i-microwave namanzi abandayo ukunciphisa amathuba okukhula kwebhaktiriya.

Ukukhenkceza yindlela esebenza kakhulu yogcino ethi icothise ngokubonakalayo ukusebenza kweentsholongwane kunye notshintsho lweekhemikhali, ukwandisa ixesha leshelufu lokutya kunye nezinye izinto ezinovakalelo.Ubuchule obuchanekileyo bokukhenkceza kunye nokunyibilikisa kunokwandisa isondlo kunye nomgangatho wokuziva wokutya.
