Umbala ophuzi osagolide wesikhupha seqanda, othandwa kakhulu ngabathengi baseSwitzerland, uncike ekudla kwesikhukhukazi nasekuphatheni umzimba. Uma lokhu kokugcina kungasebenzi, amaqanda angaba nokunambitheka okungathandwayo.
Umbala we-yolk unamandla kakhulu ekuqaleni kwesikhathi esisha sokubeka bese wehla kancane kancane. Eminyakeni engaphezu kwengu-50 edlule, u-Alfred Mehner wabhala encwadini ephathelene nokufuywa kwezinkukhu ukuthi umbala we-yolk ngokuyinhloko usekelwe ekuphakeleni. Utshani ngokuhamba kwesikhathi kanye nommbila, izaqathe, utamatisi, noma upelepele kwenza isikhuphasha sibe nombala ophuzi ocebile. Kodwa i-metabolism yesikhukhukazi ngasinye nayo ithonya umbala. Uma kungekho odayi ekudleni, akuzona zonke izinkukhu ezizosabela ngendlela efanayo. Ukuhlola kubonise ukuthi ama-acorns, i-canola, neminye imifino e-cruciferous yenza i-yolk ibonakale iyithusi noma i-olive eluhlaza. I-red egg yolk idalwe ngokungeza upelepele we-allspice.
Ama-pigments ngesimo se-carotenoids asafakwa ekudleni kwezinkukhu zokubeka namuhla. Laba badayi bemvelo banikeza umbala ophuzi kuya kobomvu. Namuhla, kunezinhlobo ezingaphezu kuka-800 zama-carotenoid aziwayo. Ukuze i-yolk yeqanda ithole umbala omuhle, i-pigment ephuzi nebomvu kufanele ibe nesilinganiso esilinganiselwe. Ekufuyweni kwezinkukhu ezithengiswayo, ukusetshenziswa kwamaqanda kamuva kudlala indima ebaluleke kakhulu. Imboni ye-pasta ibheka iqanda elinemibala eminingi ephuzi ku-yolk ngangokunokwenzeka ukuze i-pasta ikhiqize umbala ophuzi ophuzi. Emaqanda adliwayo, ama-yolks anombala osawolintshi athi mnyama, akhethwayo.
Ukudla Akuthinti Umbala Kuphela Kodwa Nokunambitha
E-Switzerland, izithwali ze-pigment zemvelo zisetshenziswa njengezithasiselo. Imbali ye-marigold ihlinzeka ngombala ophuzi futhi okukhishwe kwe-paprika kunikeza isikhuphasha seqanda umbala obomvu, njengoba kungabonakala endabeni yokufundisa ekuqeqesheni okuyisisekelo njengochwepheshe benkukhu. Kukhona nezimibalabala ezifana nezemvelo kodwa ezikhiqizwe ngokwenziwa. I-apocarotene ester ihlinzeka ngombala ophuzi olamula futhi i-canthaxanthin noma i-citranaxantine inikeza izingulube ezibomvu.
Ukondla Okuphakelayo okunengxenye ephansi yemibala ebomvu noma lezo ezinekhwalithi ephansi ye-pigment kungaholela ekukhipheni izikhupha ezinombala okhanyayo. Esinye isizathu kungaba ukudla osekugcinwe isikhathi eside kakhulu. I-pigment iyancipha ngenxa yokugcinwa, futhi lokhu konakala kwenzeka ngokushesha, ikakhulukazi emazingeni okushisa aphezulu. Esinye isizathu kungaba okuqukethwe okuphezulu kwevithamini A ekudleni. Le vithamini iqhudelana nokumuncwa kwezibala emathunjini, ngoba ama-carotenoid ayisandulela sikavithamini A. Ukuhlasela kwezikelemu kungase futhi kube nesibopho sombala ophaphathekile wesikhupha seqanda. Uma umuntu efuna ukuba nomthelela ekushintsheni kombala ngokungeza izingulube ngokudla, ukuhlolwa kwe-yolk kufanele kuphindwe ngemva kwezinsuku eziyishumi. Kuthatha isikhathi esingakanani ukuthi ukushintsha kombala kubonakale?
Ukunambitheka kweqanda lenkukhu nakho kuthonywa ukudla. Isibonelo, imbangela yephunga elingathandeki "le-fishy" emaqanda ezimweni eziningi igesi ebizwa ngokuthi i-trimethylamine, enaleli phunga. Ngokusebenza kwe-metabolism, isikhukhukazi sisebenzisa i-endogenous enzyme ukuguqula le trimethylamine ibe ifomu elingenaphunga. Kodwa-ke, uma isilwane sinenkinga ye-metabolic disorder, i-trimethylamine ayiguqulwa futhi leli "phunga elimnandi" likhula emaqandeni. Esikhathini esedlule, lokhu kuphazamiseka kwe-metabolic kwakutholakala kakhulu kuma-brown hybrids hhayi ezinkukhuni zozalo. Ingxenye ephezulu yamafutha e-unsaturated fatty acids, ukudla okonakele, noma ukudla okugcinwe isikhathi eside kungaba yisizathu sezinkinga zephunga emaqandeni.
Amaqanda Amasha Angabonwa Ngobuningi Bawo, I-Yolk, noma I-albhamuen
Kunezindlela eziningana zokuthola ukuthi iqanda lilisha noma ligcinwe izinsuku ezimbalwa. Amandla adonsela phansi athile amaqanda amasha makhulu kunawamanzi, yingakho ecwila uma uwafaka engilazini yamanzi, isibonelo. Emaqandeni amadala, ukuminyana kuyefana noma kungaphansi kwamanzi, yingakho amaqanda ame aqondile emanzini. Uma amaqanda engenakudliwa, aze antante. Isisindo seqanda sincike ngobukhulu bekamelo lomoya. Nakuba lokhu kungabonakali lapho kuhlolwa amaqanda amasha, igumbi lomoya emaqandeni angagcinwanga kahle lingaphezu kwamamilimitha ayisithupha ngobukhulu.
Enye inkomba yokusha kwamaqanda yi-yolk. Ngamaqanda amasha, lokhu akubonakali lapho kukhanyiswa, ngamaqanda amadala umthunzi we-yolk uyacaca. I-yolk iseduze negobolondo futhi yilokhu okwenza isithunzi sibonakale. Umphumela ofanayo ubonakala ngamaqanda abilisiwe. Uma i-yolk iphakathi, amaqanda ahlanzekile. Uma i-yolk iseduze negobolondo, iqanda ligcinwe isikhathi eside. Isici sokugcina ekunqumeni iminyaka yamaqanda yi-albumen. I-albumen ebonakala ngokucacile, kunalokho eqinile ezungeze isikhupha ingabonakala kuphela emaqandeni amasha. Uma i-albumen ikhukhumala futhi iba namanzi, iqanda lidala.
I-albumen incibilika ngezinqubo ze-biochemical ngesikhathi sokugcinwa. Uma izinga lokushisa lokugcina liphakeme, i-albumen izoncibilika ngokushesha. Ngenxa yokuthi iqanda elimhlophe lisabela ngokuzwela kakhulu ekushiseni okugciniwe, lisetshenziswa njengesimiso sekhwalithi ekuhwebeni kwamaqanda ngamazwe ngamazwe. Amasampula athathwa lapho ukuze kutholakale ukuthi amaqanda agcinwe ngendlela efanele yini. Kodwa-ke, hhayi kuphela isitoreji esinesibopho sokuvumelana kweqanda elimhlophe. Iminyaka yezikhukhukazi ezizalela nayo inethonya ekukhuleni kweqanda elimhlophe. Uma isikhukhukazi sisindala, iqanda liyoba mnyama ukuminyana bese kuthi iqanda libonakale lisha kancane ngokwalokhu kuhlolwa kwezimpahla. Lesi sampula esingahleliwe sisasebenza ekuzaleleni izinkukhu ezithengiswayo ngoba zonke izinkukhu zinonyaka owodwa kuphela ubudala futhi zinokufana okuningi mayelana nendlela yokuzalanisa kunezinhlobo ezahlukene zabafuyi abazilibazisa.
