Yini Eyenza Umgogodla Wezinkomo Olubomvu?
Zonke izilwane ezifudumele zineziqu ezibizwa ngokuthi i-myoglobin emathisini abo omzimba.
Le pigment ngokuvamile i-gray grey-purple, kodwa uma ihlangana ne-oksijeni, iba i-oxymyoglobin futhi iphendulela umbala obomvu obomvu.
Ukuze uthole umbala othakazelisayo emehlweni, inkabi eningi engaphansi yithengiswa emaphakheji acacile wefilimu ekwazi ukukhipha umoya. I-oksijini iyadlula kule filimu futhi ivumela inyama ukuba iphendule leyo mbala obomvu obomvu esihlangana nayo yenkomo entsha. Lokhu kuphelelwa yisizathu kungenxa yokuthi akusikiswanga ukufakela inyama ekupaketheni esitolo.
Ngenkathi ngokuvamile ungadingeki ukhathazeke ngokuphepha kwenyama esanda kuthengwa ukuthi yini efrijini yakho enye indaba. Imibala ingabonisa futhi ukuphazamiseka. Uma iphakheji yakho yenkomo yenkomo ibe yi-grayish yonke indlela futhi ingaphenduki uma ivuliwe emoyeni imizuzu eyishumi nesishiyagalolunye noma kunjalo, kungenzeka ukuthi yonakaliswe. Ngokuvamile, ikhala lakho lizokutshela ngqo ku-bat, njengoba inyama yenkomo ewonakele iyophunga omuncu. Kuzophinde uzizwe unamathele ekuthinteni.
Ungathathi noma yikuphi amathuba nge inyama eyonakele. Uma ungabaza, yiphonsa.
Ukuphatha Ngokuphephile Kwenkomo Yenkomo
Imikhiqizo yenyama yenkomo ingangcoliswa yi-E. coli, i-salmonella ne- listeria . Ukuphatha ngokufanele nezinqubo zokupheka kubalulekile ukuvimbela ukugula okubangelwa ukudla. Amanye amabhaktheriya angabamba iqhaza ekukhusheni ngokushesha.
I-Ground yenkomo isengozini ikakhulu ngoba iqala ngezingcezu eziningi zenyama ezivezwe ezinkambisweni eziningi zokuphatha kanye nemishini. Ukugaya kuveza ngisho nenyama ngaphezulu kubhaktheriya.

Sebenzisa i-thermometer yenyama ukuze uqiniseke. Khumbula, lokhu kungukushisa okuphakeme kunenkomo engavamile kakhulu noma engavamile. I-USDA manje idinga ulwazi lokuphatha ngokuphephile nokuqondisa ukupheka lixhunywe kuyo yonke inyama yenkomo eboshiwe edayiswa e-USA.
Ukuhlanzeka lapho kusingatha inyama yenkomo kubaluleke kakhulu. Lokhu akubandakanyi izandla zakho kuphela kodwa izitsha zakho kanye nezindawo zokusebenza. Ungasebenzisi izitsha ezifanayo noma iziqukathi zenyama nemifino. Ukusebenzisa ummese ofanayo ukusika imifino kungcolisa inkomo yakho ephephile ngaphambili futhi ngokuphambene nalokho. Ukungcola okuphambene nomzimba yiyona ethandwa kakhulu kunazo zonke ezibhekene nokugula okuphethwe ukudla. Zonke izinto kufanele zihlanzwe kahle ngesipho namanzi ashisayo ngaphambi kokusebenzisa kunoma iyiphi enye ukudla.
