Ta yaya zan iya guje wa kwai ya zama kore lokacin dafa abinci?

Don guje wa gwaiwar kwai daga komawa kore lokacin tafasa:

• ajiye ruwan a tafasasshen zafi ko kuma ƙasa da zafin zafi don hana zafi
• Yi amfani da babban kwanon rufi kuma ajiye ƙwai a cikin Layer guda ɗaya
• kashe wuta lokacin da ruwan ya kai zafin zafi
• kar a bar qwai a cikin ruwa na dogon lokaci; Minti 10-12 ya isa ga matsakaicin girman ƙwai
• kwantar da ƙwai da ruwan sanyi nan da nan bayan dafa abinci don dakatar da duk wani halayen sinadarai mai juya yolk kore

Makullin shine ƙara isasshen zafi don sanya kwan ya yi ƙarfi, amma ba sosai har ya zama kore ba.

Menene cikakken tsarin sinadarai wanda ke mayar da gwaiwar kwai kore lokacin da ake dafawa?

Wasu matakai masu ban sha'awa na sinadarai suna faruwa kafin ƙarfe ya iya amsawa da sulfur don juya kwai gwaiduwa kore.

Bari mu wuce su mataki-mataki.

Iron a cikin Kwai Yolk

Kwai kwai kaji ya ƙunshi kashi 2.7% na baƙin ƙarfe, wani muhimmin sinadari mai mahimmanci ga amfrayo. 95% na baƙin ƙarfe yana ɗaure da phosvitin, furotin a cikin kwai gwaiduwa.

Lokacin da amfrayo ya fara girma, tasoshin jini suna girma zuwa gwaiduwa don debo abubuwan gina jiki.

Jinin ya ƙunshi jajayen ƙwayoyin jini waɗanda ke amfani da ƙarfe don ɗaukar iskar oxygen zuwa kajin mai tasowa.

Chicken da ba a haifa ba yana shakar iskar oxygen a cikin kwai. Iskar iskar oxygen tana zuwa ta ƴan ƙananan pores a cikin kwai. Daidaitaccen kwai na kaza yana da fiye da pores 7000 don iskar oxygen wucewa.

Sulfur a cikin Farin Kwai

Dukanmu mun san sulfur kamar yadda tafin kafa ke da alhakin ƙamshin ruɓaɓɓen qwai.

Farin kwai yana zaune a kusa da gwaiduwa a matsayin kariya mai kariya wanda ke kashe ƙwayoyin cuta masu shigowa. An cika shi da ruwa da sunadarai. Fiye da rabin farin kwai ya ƙunshi furotin ovalbumin, furotin wanda ya ƙunshi ƙungiyoyin sulfhydryl kyauta masu ɗauke da sulfur.

Cysteine

Sunadaran kwai dogayen sarƙoƙi ne na amino acid. Yawancin sulfur a cikin ƙwai kaji yana ƙunshe a cikin mahimman amino acid methionine, mafarin amino acid cysteine.

A cikin mutane, cysteine ​​yana taka muhimmiyar rawa a cikin narkewar barasa. Ya zama sananne a cikin 2020 lokacin da masana kimiyya suka gano cysteine ​​na iya rage alamun cutar barasa, kamar tashin zuciya da ciwon kai. Cystine mai sulfur mai ƙunshe da ƙwai a cikin qwai yana warkar da hangula.

Dumama Kwai

Lokacin da kwan yayi sanyi, membrane na vitelline shine shinge wanda ke kiyaye sinadarai da ke cikin gwaiduwa daga farin kwai. Amma lokacin da kuka fara dafa kwai, abubuwa biyu na sihiri suna faruwa.

Da farko, zafi yana sa sunadaran da ke cikin ɗanyen kwai su buɗe kuma su samar da sabon alaƙa da juna. Ana kiran wannan tsari denaturation kuma shine dalilin da yasa kwan ya yi tauri lokacin da kuka tafasa shi.

Saboda duk rashin daidaituwa, sulfur yana fitowa daga amino acid. Ya fara samar da hydrogen sulfide, iskar gas mai kamshin ruɓaɓɓen kwai. Mun yi sa'a wannan ƙaramin iskar gas ne, ko ba za mu ci ƙwai ba, har abada.

Dukanmu mun san abin da ke faruwa tare da soda idan muka bar shi a cikin rana na dogon lokaci: iskar gas ya tsere. Hakanan yana faruwa tare da hydrogen sulfide, yana ƙoƙarin tserewa daga farin kwai. Babu wurare da yawa da iskar gas zai bi, don haka yana ƙoƙarin yaduwa cikin gwaiwar kwai.

Lokacin da kuka zafi kwai da tsayi sosai kuma a yanayin zafi mai yawa, in ba haka ba sunadaran phosvitin masu ƙarfi a cikin gwaiduwa suna fara rushewa ta hanyar hydrolysis. phosvitin ba zai iya riƙe baƙin ƙarfe ba, kuma baƙin ƙarfe yana fitowa a cikin gwaiduwa.

Iron yana amsawa tare da Sulfur

Iron (Fe) daga gwaiduwa ya hadu da sulfur (S) daga farin kwai a gefen gwaiduwa, inda membrane vitelline ke fadowa. Sakamakon sinadaranyana samar da ferrous sulfide(FES).

Ferrous sulfide shine baƙin ƙarfe sulfide mai launin duhu wanda yayi kama da kore idan an haɗe shi da gwaiduwa rawaya. Sakamakon ƙarshe shine launin kore-baƙar fata da kuke samu a cikin kwai da aka dafa.

Wasu kafofin suna da'awar kore shine ferric sulfide, amma wannan wani abu ne na wucin gadi wanda baya faruwa a cikin yanayi kuma yana lalacewa a cikin sulfide na ferrous.

Wadanne abubuwa ne ke kara hadarin kwai ya zama kore?

Haɗarin launin toka-kore na gwaiwar kwai yana ƙaruwa lokacin:

• ana dafa kwan a yanayin zafi sosai
• kwan yana zafi na tsawon lokaci
• ana adana kwan kafin a dafa
• kwai gwaiduwa yana da manyan matakan pH
• kina dafa ƙwai a cikin kwanon ƙarfe

Matakan pH na kwai suna ƙaruwa lokacin da kwan ya tsufa. pH na iya canzawa zuwa ƙimar alkaline, tare da carbon dioxide yana barin kwai a cikin 'yan kwanaki. Wannan yana ƙara haɗarin cewa ƙarfen gwaiduwa yana amsawa tare da sulfur na farin kwai.

Tun da baƙin ƙarfe yana juya kwai kore, yana da kyau a guji dafa su a cikin tukunyar simintin ƙarfe.

Irin kajin, girman kwai, launin kwai, da ingancin kwai ba sa shafar koren gwaiduwa.

Takaitawa

Launin launin toka-kore na gwaiwar kwai a cikin dafaffen ƙwai yana faruwa ne ta hanyar yin yawa. Zafin yana sa ƙarfe a cikin kwai gwaiduwa ya amsa tare da sulfur a cikin farin kwai. Sakamakon duhu ferrous sulfide yayi kama da kore a saman gwaiwar kwai rawaya.

Don guje wa koren tinge, yana da mahimmanci don hana ƙarfe a cikin gwaiduwa daga sakin. Rage zafin ruwa kuma tabbatar da kwan ya yi zafi ne kawai don yin tauri. Nan da nan a kwantar da shi da ruwan sanyi bayan dafa abinci.
