Amaqanda enkukhu enye yezona zinto zixabisekileyo kwiimveliso zabantu. Ukubunjwa kweqanda lezinkuni kubandakanya imfuneko yokusebenza kwamaprotheni omzimba kunye namafutha, kunye nezixhobo ezahlukahlukeneyo eziphilayo eziphilayo- iivithamini , izinto ezincinci kunye nezikhulu.
Ukwakhiwa kwamachiza amaqanda enkukhu
Ukwenziwa kweekhemikhali yenkomo yenkukhu iqulethe:
- amanzi 74%;
- Iiprotheni - 12.5%;
- amafutha - 12%
- i-carbohydrate - 0,5%;
- izixhobo zamaminerali kunye namavithamini - 1%.
Ukubunjwa kweprotheni yenkukhu yenkukhu ihluke kwi-yolk, ngenxa yokuba ayinayo ifama kwaye inomxholo ophezulu wamanzi. Kwaye i-yolk, ngokungafani neprotheni, iqukethe amancinci ambalwa kakhulu. Ixabiso lentengo yenkukhu yenkukhu i-47 kcal (157 kcal nge 100 g). Ingxenye ebalulekileyo yekhalori yeqanda (i-75%) ingeyesikhupha.
Iiprotheni zibonelela ngexabiso elincinci lokutya kweqanda lomkhuhlane. Ama-amino acids kwinkukhu yamaqanda agcinwa ngokulinganayo, ngoko anqunywa ngumzimba phantse i-100%. Ngenxa yalesi sizathu, abantu abancinci kunye nabadlali bama-muscle-building bavame ukusebenzisa kuphela amaqanda abamhlophe.
I-yolk yeqanda le inkukhu liyingxenye yesithathu yeoli, inxalenye ebalulekileyo yinto ebaluleke kakhulu ye-fatty unsaturated fatty acids. Iingxabano malunga neengozi kunye neenzuzo zesikhupha seqanda phakathi kwabafundi bezilwanyana ezifayo kubhenela i-cholesterol. Nangona kunjalo, kwelinye iqanda alikho kakhulu - ngaphantsi kwezinga lemihla ngemihla. Ukongezelela - i-yolk cholesterol "ayifumananga" ngenye inxalenye yeqanda - lecithin.
Ukusetyenziswa kwamaqanda kwandisa i-vitamins (A, E, PP, D, H, K kunye ne-B), kunye nokuveliswa kwamaminerali, okuquka i-calcium, i-phosphorus, i-magnesium, i-potassium, i-sodium, isulfure, isinyithi kunye nezinye ezifunekayo kwimpilo izinto.
Ukuthetha ngokubunjwa kweqanda le inkukhu, awukwazi ukulikhumbula ngegobolondo yalo. Icandelo eliphambili legobolumu - i-calcium, kodwa liquka malunga nezinye iingu-30 nezinye izinto ezinobuncitshisi ezifanelekileyo.
Ingozi yenkukhu yamaqanda
Ngenxa yomxholo weproduct ovomucoid kwiqanda, le mveliso inamandla kakhulu. I-Ovomukoid ibangela ukungaphumeleli ekuveliseni i-enzyme yi-pancreas, ekhokelela ekutyeni kokutya okungaphelelanga kunye nokugqithisa kweempawu zokugula. Nciphisa umxholo ekudleni kwamaqanda kufuneka ube neengozi zengqondo, isifo sesibindi, isifo kunye ne-gallbladder, izifo zesikhumba. Ukongezelela, amaqanda anokuba ngumthombo weebhaktheriya ze-pathogenic. Enye yeyona pathogenic kakhulu i-salmonella. Ukukhusela kule microorganism, oogqirha bancoma amaqanda okupheka ubuncinane imizuzu engama-8 emva kokubilisa.
