Ukutya okune-freze-eyomileyo, kuvunyiwe njengokutya kwe-FD, kuveliswa kusetyenziswa itekhnoloji yokuqhekeka kwe-vacuum. Ezi mveliso zinokugcinwa kubushushu begumbi ngaphezulu kweminyaka emihlanu ngaphandle kokuzigcina, kwaye zilula, zenza ukuba zilula ukuzithwala nokuhamba.
UkusebenzisaI-freeze yomile, le teknoloji yokomisa i-vacuum igcina ngokufanelekileyo umbala, incasa, kunye nesondlo, ivumba layo, incasa kunye nezondlo ezinokubakho njengeevisini kunye neeprotein. Phambi kokusetyenziswa, ukulungiselela okuncinci kuyivumela ukuba iphinde iphinde iphinde ifunwe ukutya okutsha kwimizuzu embalwa. Ngaphezulu, ukutya okunemoto ngokungahambiyo ayifuni ifriji kwaye inokugcinwa, ithuthwe, kwaye ithengiswe kubushushu begumbi emva kokuba itywinwe ukupakisha.
1. Inkqubo: Ukutya okune-freeze eyomileyo vs.
Ukuphelelwa ngamanzi emzimbeni:
Ukupheliswa kwempahla emfutshane, ekwabizwa ngokuba yi-thermal eyomileyo, yinkqubo yokomisa esebenzisa omabini abathwali be-shirmal kunye ne-morriester. Ngokwesiqhelo, umoya oshushu usebenza njengobushushu kunye ne-suriture parriers. I-air eshushu ishushu kwaye emva koko isetyenzisiwe kukutya, ichukumise umswakama ukukhupha kwaye igcinwe umoya.
Ukuphelelwa ngamandla enzonzobila kusebenza ngokudlulisela ubushushu ngaphandle nangaphandle komswakama ngaphakathi, onokukunqongophala kwawo. Ukuba iqondo lobushushu liphezulu kakhulu, inokubangela ukuba umhlaba ungaphandle, ucothe inkqubo yokomisa, ngelixa amaqondo obushushu anokukhokelela ekungasebenzi kakuhle. Ukuxinana okugqithisileyo umnyhadala kunokubangela iindonga zeseli ukuba ziye kuqhekezwa, kukhokelela kwilahleko yesondlo.
I-freeze-eyomisa:
Ukusoma kwekhulu kubandakanya ukunciphisa umswakama, ngelixa ukhutshiwe ixhomekeke ekuphumeni. Kwi-freeze-eyomisayo, ukutshintsha umswakama ngokuthe ngqo kwigesi, ukugcina imeko yokutya. Ngokwahlukileyo, ukupheliswa kwempahla emzimbeni kutshintsha umswakama ukusuka kulwelo kwigesi.
Okwangoku, ukomisa i-vacuum-eyomileyo yeyona ndlela ifanelekileyo. Ngaphantsi kweqondo lobushushu elisezantsi, iimeko zoxinzelelo oluphantsi, ulwakhiwo lokutya luhlala ubukhulu becala, ukuthintela ukuntywila ngenxa yokufuma okwenziwa yi-galodient. Le ndlela ikwandisa inqaku eliphantsi, okukhokelela ekusebenzeni okuphezulu kokukoma.
I-2. Iziphumo: Ukutya okune-freeze
Beka ubomi kwishelufa:
Ireyithi yokukhupha umswakama ibuchaphazela ngokuthe ngqo ubomi beshelheli. Ukutya okunehrentshi njengeziqhamo ezomileyo, imifuno, kunye nemibhobho yobomi beshelufa yeminyaka eli-15 ukuya kwengama-20; Sithandwa, iswekile, ityiwa, ingqolowa enzima, kwaye i-oati ingahlala ngaphezulu kweminyaka engama-30. Ngokwahlukileyo, iziqhamo ezomileyo ezomileyo kunye nemifuno zinokuhlala iminyaka engama-25 ukuya kwengama-30.
Umxholo wesondlo:
Ngokutsho koPhando oluvela kwimibutho yezeMpilo, eyomileyo igcina uninzi lweevithamini kunye neeminerals. Nangona kunjalo, ukutya okuhlumayo kunokungabikho kwiivithamini ezithile, ezinjengeVitamin C, eneengxaki ngokukhawuleza. Ukuphelelwa ngumzimba akutshintshanga umxholo wefibre okanye umxholo wentsimbi, kodwa kunokukhokelela ekuqhekekeni kweevithamini kunye neeminerals ukutya okuphelileyo okunesondlo kunokutya okunesondlo emzimbeni. Ilahleko yesondlo inokwenzeka kwiivithamini A kunye ne-C, niacin, iRiboflavin, kunye ne-thiamine ngexesha lokuphelelwa ngumzimba.
Umxholo wokufuma:
Eyona njongo iphambili yokugcinwa kokutya kukususa umswakama, ukuthintela i-spoilage kunye nokukhula kobumba. Ukuphelelwa ngumzimba kususa i-90-95% yokufuma, ngelixa i-freeze -at yokutsalwa inokuphelisa i-98-90%. Ukupheliswa kwempahla yasekhaya kuhlala kushiya malunga ne-10% yokufuma, ngelixa iindlela zokuguqulelwa zizihlazo zinokufezekisa ubomi obude beshelufa.
Imbonakalo kunye ne-Gekter:
Omnye womahluko ophambili phakathi kokutya okunemilenzeki kwaye ukhululekile kukubonakala kwawo. Ukutya okunehukrazi kube brittle kwaye kunzima, ngelixa ukutya okune-freeze imitshato ethambile ngokukhawuleza xa ungena emlonyeni. Ukutya okunentloko
Ukupheka:
Ukutya okunehrentshinti kufuna ukupheka ngaphambi kokusetyenziswa kwaye kuhlala kufuna ixesha elithile. Oku kuthetha ukuchitha ixesha ukubilisa iimveliso ngamanzi ashushu ngaphambi kokutya. Ukulungiselela ukutya okuphelileyo kunokuthatha phakathi kwemizuzu eli-15 ukuya kwiiyure ezi-4. Ngokwahlukileyo koko, ukutya okhlisayo okhwalayo kufuna kuphela amanzi abilayo; Yongeza amanzi ashushu okanye obandayo kwaye ulinde imizuzu emi-5 yokutya.
Ukuqukumbela, kucacile ukuba loluphi uhlobo lokutya olunokukhula ngcono kwimarike yanamhlanje. Ukutya okuluhlaza kunye nempilo kuya kuba yimeko elandelwa ngabantu.
Ukuba unomdla kwi-Ukutya Umatshini wokulolozaokanye unemibuzo, nceda uzive ukhululekileQhagamshelana nathi.
