Ngingakugwema kanjani iqanda ekuguqukeni luhlaza lapho ngipheka?

Ukugwema i-yolk yeqanda kusuka ekuguqukeni kokuluhlaza lapho kubila:

• Gcina amanzi emazingeni okula abilayo noma ngaphansi kwamazinga okubila abilayo ukuvikela ukushisa ngokweqile
• Sebenzisa i-pan enkulu futhi ugcine amaqanda ungqimba olulodwa
• cisha ukushisa lapho amanzi efinyelela emazingeni okushisa abilayo
• Ungavumeli amaqanda emanzini isikhathi eside kakhulu; Imizuzu engu-10-12 yanele amaqanda aphakathi
• Chill amaqanda ngamanzi abandayo ngokushesha ngemuva kokupheka ukumisa noma yikuphi ukusabela kwamakhemikhali kuguqula i-yolk luhlaza

Isihluthulelo ukwengeza ukushisa okwanele ukwenza iqanda kube nzima, kepha hhayi kakhulu kangangokuba uphenduka uluhlaza.

Iyiphi inqubo ephelele yamakhemikhali eguqula i-yolk yeqanda eluhlaza lapho isebenza ngokweqile?

Izinqubo ezimbalwa ezithokozisayo ze-biochemical zenzeka ngaphambi kokuba insimbi ingasabela ngesibabule ukuguqula i-yolk yolk eluhlaza.

Ake sibe ngaphezulu kwabo ngesinyathelo ngesinyathelo.

I-iron ku-yolk yeqanda

I-yolk yeqanda yenkukhu iqukethe i-2.7% yensimbi, isakhi esibalulekile sombungu. I-95% yensimbi iboshelwe ePhosvitin, iprotheni kwi-yolk yeqanda.

Lapho umbungu uqala ukukhula, imithambo yegazi ikhula ibe isikhuphamu sokulanda izakhi zomzimba.

Igazi liqukethe amangqamuzana abomvu egazi asebenzisa insimbi ukuthwala umoya-mpilo ku-chick ekhulayo.

Ikunyane elingakazalwa empeleni liphefumula umoya-mpilo ngaphakathi kweqanda. I-oksijini iza ngokusebenzisa ama-pores amancane e-egghell. Iqanda lezinkukhu elijwayelekile linama-pores angaphezu kuka-7000 okudlula ku-oxygen.

Isibabule eqanda elimhlophe

Sonke sazi isibabule njengoba kungukuphela kwephunga le-pungent lamaqanda abolile.

Iqanda elimhlophe lihlala e-yolk njengongqimba oluvikelayo olubulala amagciwane angenayo. Igcwele amanzi namaprotheni. Ngaphezu kwengxenye yeqanda elimhlophe liqukethe iprotheni ovalbumin, amaprotheni aqukethe amaqembu wamahhala we-sulfhydryl aqukethe isibabule.

I-cysteine

Amaprotheni amaqanda amaketanga amade ama-amino acid. Iningi lesibabule kumaqanda enkukhu liqukethe i-amino acid methtionine, isandulelo se-amino acid cysteine.

Kubantu, i-cysteine ​​idlala indima ebalulekile ekugayweni utshwala. Kwathandwa ngo-2020 lapho ososayensi bethola i-cysteine ​​bengadambisa izimpawu ezihlobene notshwala ze-hangover, njenge-nausea kanye nekhanda. I-cysteine ​​equkethe i-cysteine ​​yamaqanda elapha ama-omorers.

Ukufudumeza iqanda

Lapho iqanda libanda, ulwelwesi lwe-vitelline luyisithiyo esigcina amakhemikhali e-yolk ahlukaniswe neqanda elimhlophe. Kepha uma uqala ukupheka iqanda, kwenzeka izinto ezimbalwa zemilingo.

Okokuqala, ukushisa kwenza amaprotheni eqanda elingavuthiwe aqhamuke futhi akha izibopho ezintsha. Le nqubo ibizwa ngokuthi yi-denaturation futhi yisizathu esenza ukuthi iqanda liba nzima lapho ubilika.

Ngenxa yawo wonke ama-utangling, isibabule akhishwa kuma-amino acid. Kuqala ukwakha i-hydrogen sulfide, igesi enuka njengamaqanda abolile. Sinenhlanhla yimali encane kagesi, noma besingeke sidle amaqanda, njalo.

Sonke siyakwazi ukuthi kwenzekani nge-soda uma sikushiya elangeni isikhathi eside kakhulu: Ukuphunyuka kwegesi. Kwenzeka okufanayo nge-hydrogen sulfide, izama ukuphunyuka eqanda-mhlophe. Azikho izindawo eziningi kakhulu zegesi okufanele zihambe, ngakho-ke izama ukuhlukanisa iqanda leqanda.

Lapho ushisa iqanda isikhathi eside ngokwanele futhi emazingeni okushisa aphezulu, amaprotheni aqinile we-phosvitin e-yolk aqala ukubhidliza nge-hydrolysis. I-phosvitin ayikwazi ukubamba insimbi, futhi insimbi ikhululwa e-yolk.

I-iron iphendula ngesibabule

I-Iron (FE) kusuka kwi-yolk ihlangana nezibabule (ama) esibabule kusuka eqanda elimhlophe emaphethelweni we-yolk, lapho ulwelwesi lwe-vitelline luwa. Ukusabela kwamakhemikhalikukhiqiza i-sulffide ye-ferrous(FES).

I-Ferrous Sulfide iyi-sulfide yensimbi emnyama ebukeka iluhlaza uma ixubene ne-yolk ephuzi. Umphumela wokugcina uwukudilika okuluhlaza okotshani owuthola eqanda eliphekwe kanzima.

Eminye imithombo ifuna okuluhlaza ku-ferfide ye-ferfide, kepha lokho kungazenzisi izinto zokufakelwa ezingazinzile okungenzeki emvelweni nasekuboleni i-sulfide ye-ferrous.

Yiziphi izinto ezandisa ubungozi be-yolk yeqanda ephenduka kube luhlaza?

Ingozi yokuqothuka okuluhlaza okotshani kweqanda leqanda inyuka lapho:

• iqanda liphekwe emazingeni okushisa aphezulu kakhulu
• Iqanda lifudunyezwa isikhathi eside
• Iqanda ligcinwa isikhathi eside ngaphambi kokupheka
• I-yolk yeqanda inamazinga aphezulu we-pH
• Upheka amaqanda epanini lensimbi

Amazinga we-PH ukunyuka kwamaqanda lapho iqanda likhula. I-PH ingashintshela kumanani we-alkaline, nge-carbon dioxide eshiya iqanda ezinsukwini ezimbalwa. Lokhu kwandisa ingozi yokuthi insimbi ka-yolk iphendula ngesibabule seqanda esimhlophe.

Njengoba i-iron iguqula i-green green, kungcono ukugwema ukuwapheka e-cast iron skillet.

Uhlobo lwenkukhu, usayizi weqanda, umbala weqanda, nekhwalithi yeqanda akuthinti ukuhlukahluka okuluhlaza kwe-yolk.

Ukubeka kafushane

I-grey-green disciloration ye-yolk yeqanda ngamaqanda abiliswe kanzima kubangelwa ukweqiwa. Ukushisa kwenza i-iron kumaqanda amaqanda izikhundla isabele ngesibabule kuma-whites amaqanda. I-sulffide emnyama ephumile ibukeka iluhlaza ngaphezulu kwe-yolk yeqanda ephuzi.

Ukugwema i-tinge eluhlaza, kubalulekile ukuvikela insimbi e-yolk ukuthi ikhishwe. Yehlisa izinga lokushisa lamanzi futhi uqinisekise ukuthi iqanda lifudumeza kuphela isikhathi eside ukwenza kube nzima. Masinyane uyiphole ngamanzi abandayo ngemuva kokupheka.
