Kwenguva yakareba, chitendero chakakurumbira chokuti kudyiwa kwemazai, uye kunyanya mazai evha, yakanga yakabatana nezvinetso zvehutano yakapfuudzwa. Kutenda uku kwakatsigirwa nenyanzvi dzehutano. Parizvino, kwave nezvidzidzo zvesainzi zvakawanda zvinotsigira kudyiwa kwemazai uye kunyanya yolk.
Zvadaro, tichatsanangura kukosha kwekushandiswa kweii yolk yezvokudya zvine utano.
Mazai
Zai chikafu chine mapuroteni nemafuta. Iwo akapfuma muvhitamini (kunyanya b12, b1, b3, folic acid, A, D uye E) uye maminera akakosha.
Zai rinoumbwa nezvikamu zvitatu:
- Shell. Inomiririra 10,5% yehuremu hwezai.
- Bud. I 31% yehuremu hwezai.
- Clara. Icho chikamu chakawanda kwazvo chezai, chinomiririra 58,5% yehuremu hwezai.
Kukosha kweiyo yolk
Zai jena rine mapuroteni akawanda ezai, zvisinei, iyo yolk inopa mafuta uye cholesterol, pamwe chete nevakawanda mavitamini nemaminera.
Zai rezai rinopa mavhitamini anonyungudika mumafuta, akadai seA, D, E, uye K, mavhitaminzi B6, B12, folic acid, pantothenic acid, uye thiamine, pamwe chete nezvimwe. yakakosha mafuta acids. Ichi chikamu zvakare chakapfuma mumaminerari, senge calcium, iron uye phosphorus muhuwandu hwakawanda, izvo zvichatibatsira kusangana nezvinodiwa zvemicronutrients mukudya.
Mafuta ari muzai rezai anosiyana pakati pe4-4,5 magiramu pachikwata, iyo 1,5 magiramu ane mafuta akazara uye mamwe ose haana unsaturated, umo mafuta anowedzera. rakna, izvo zvinobatsira kumuviri.
mariri colina, inokurudzirwa muvakadzi vane pamuviri. Iri ndiro basa rekufambisa central nervous system kukura ye embryo uye fetus. Zvakare, kuvapo kwecholine, yakashandurwa kuita acetylcholine, ichabatsira kuvandudza ndangariro.
Chimwe chinhu chekusimbisa ndeye zviri mukati lecithin, izvo inoderedza intestinal absorption yecholesterol mumuviri.
Cholesterol gakava
Kunyange zvazvo egg yolk ine cholesterol, haibatsiri zvakanyanya cholesterol yeropa muvanhu vane hutano, sezvo isiri iyo inonyanya kukonzera kuwedzera.
Zvave zvichiratidzwa kuti chii chine mhedzisiro yakaipa paropa cholesterol ndeye hukama pakati pekushandiswa kwemafuta akazara pamusoro pemafuta asina unsaturated uye kwete cholesterol yezvokudya, sezvaidavirwa zvisizvo.
Muchidimbu, kana kudya kwakanaka uye kwakadzikama kunoteverwa, nekushandiswa kwakakwana kwemafuta asina kusimba uye kutonga kwemafuta akazara, hapazovi nematambudziko echolesterol.
