I-Trinidad kunye neTobago Ukugcinwa kwezilwanyana zaselwandle ezibandayo

Ixabiso lokugcinwa okubandayo lifanele libalwe njani?Ziziphi izinto ezichaphazela ixabiso lokugcina elibandayo?Ndiyakholelwa ukuba abathengi abaninzi banenkxalabo ngalo mba.Ndiza kukwazisa ukuba zeziphi izinto eziqwalaselwa ngokukodwa kwixabiso lokugcinwa okubandayo.

    1. Indawo yokugcina ebandayo-ubushushu be-ambient yangaphandle

    Ukwakhiwa kwendawo yokugcina ebandayo kuthintelwe ngumahluko wobushushu phakathi kwangaphakathi nangaphandle kwendawo yokugcina ebandayo kunye nomahluko kuxinzelelo oluyinxenye lomphunga wamanzi.Ngokobume bendawo yokugcina ebandayo, ubushushu bexesha elide lwangaphakathi lwendawo yokugcina ebandayo buphakathi kweqondo lokushisa elingama-40.°C~0°C.Ukuguquguquka kwamaxesha, okudityaniswa nesidingo sokuvulwa rhoqo kweengcango kwimisebenzi yemveliso yokugcina ebandayo, ekhokelela kutshintshiselwano lobushushu, ubushushu kunye nokufuma phakathi kwangaphakathi nangaphandle kwendawo yokugcina ebandayo, kubangele ukuba izakhiwo zogcino ezibandayo zithathe amanyathelo ahambelanayo obuchule bokufakelwa kobushushu. kunye nokugquma komphunga ukuziqhelanisa neempawu zogcino olubandayo.Oku kwakhona umahluko phakathi kokwakhiwa kokugcinwa okubandayo kunye neempawu zezakhiwo eziqhelekileyo.

    2. Ubungakanani bendawo yokugcina ebandayo

    Ubungakanani kunye nenani leefriji zihambelana nobukhulu bokugcinwa okubandayo.

    3. Yintoni indawo yokugcina ebandayo esetyenziselwa ukugcina?

    Ubushushu obufunekayo ekugcinweni kwezinto ezahlukeneyo buhluke, imifuno ngokubanzi igcinwa isitsha kwi-0°C, kwaye inyama ifakwe efrijini kwi -18°C.

    4. Iqondo lobushushu elifunekayo ukufikelela kwindawo ebandayo

    Ukugcinwa okubandayo kunokwahlulwa ngokweendidi ezine: ubushushu obuphezulu, ubushushu obuphakathi, ubushushu obuphantsi kunye nobushushu obuphantsi kakhulu.ngesiqhelo:

    Ubushushu bokugcina ubushushu obuphezulu buyi-10°C~+8°C, efanelekileyo ukugcinwa kweziqhamo kunye nemifuno;iqondo lobushushu eliphakathi kwifriji yi -10°C~-23°C, efanelekileyo kwifriji yokutya okufriziwe;iqondo lobushushu kwiqondo eliphantsi logcino ebandayo jikelele -23°C~-30°C, ilungele ifriji yeemveliso zasemanzini ezikhenkcezisiweyo kunye nokutya kweenkukhu;iqondo lobushushu elisezantsi kakhulu lokukhenkceza ngokukhawuleza yi -30°C~-80°C, ilungele unyango olukhawulezayo lomkhenkce phambi kokuba iimveliso ezitsha zifakwe efrijini.

    Izinto ezilungileyo zokugcina ukutya okubandayo:

    1. Imisebenzi yezinto kunye ne-enzymes nazo zivinjelwe, i-metabolism iyonke iyancipha, kwaye ixesha lokugcinwa kweziqhamo kunye nokutya kwemifuno lide.Xa iqondo lobushushu linyuswa kwindawo ebandayo yogcino lize lithengiswe kwiqondo lobushushu begumbi, incasa yokuqala kunye nokutsha kuyabuyiselwa, kwaye iinzuzo zoqoqosho ziqinisekiswa ngokusebenzayo.

    2. Ukwakhiwa kokugcina ukutya okubandayo.Ukutya kwenyama kucutshungulwa ngokugcinwa okubandayo.Ukuba yehla ukuya ku-0°C, inyama ngokwayo ayiyi kuba ngumkhenkce.Ngexesha elifanayo, ukukhula kunye nokuveliswa kwe-spoilage microorganisms kuya kuncipha.Ixesha elitsha kunye nomgangatho nazo ziqinisekisiwe kakuhle.Sihlala sisithi "ipholile ipholile";ukuba ihla ukuya kumaqondo aphantsi, njenge -18°C nangaphantsi, ukufuma kwenyama kunye nejusi iya kutshintsha ukusuka emanzini ukuya kumkhenkce ngexesha elifutshane, kwaye ayiyi kukwazi ukubonelela ngamanzi ayimfuneko kubomi be-microbial.Kwangaxeshanye, ubushushu obuphantsi buphinda buthintele ukukhula kunye nokuveliswa kwee-microorganisms, ezinokuthi ziphucule kakhulu ukumelana nokugcinwa kweemveliso zenyama kunye nokufezekisa ukuthengisa okude kunye nexesha elide.

    3. Ukwakhiwa kokugcinwa kokutya okubandayo Ngexesha lenkqubo yokufakwa kwifriji yokutya, ukutya ngokwayo kuqulethe izondlo ezifana neswekile, iiprotheni, amafutha, kunye neetyuwa ze-inorganic, ezingayi kulahleka, ukuze incasa yokutya ihlale ifana xa kutyiwa. kwiqondo lobushushu begumbi.
