Pehea e pale aku ai i ka ʻōmaʻomaʻo o ka hua i ka wā e kuke ai?

No ka pale ʻana i ka ʻōmaʻomaʻo o ka hua manu i ka wā e hoʻolapalapa ai:

• e mālama i ka wai ma nā mahana paila a i ʻole ma lalo o nā mahana e hoʻolapalapa ai i mea e pale ai i ka wela
• e hoʻohana i ka pā nui a mālama i nā hua i kahi papa hoʻokahi
• e hoʻopau i ka wela ke hiki ka wai i ka mahana wela
• mai hoʻokuʻu i nā hua i loko o ka wai no ka lōʻihi; Ua lawa nā minuke 10-12 no nā hua liʻiliʻi
• e hoʻomaloʻo i nā hua me ka wai anuanu ma hope koke o ka kuke ʻana i mea e hoʻopau ai i nā hopena kemika e hoʻohuli i ka ʻōmaʻomaʻo yolk

ʻO ke kī, ʻo ka hoʻohui ʻana i ka wela i mea e paʻakikī ai ka hua, akā ʻaʻole nui a lilo i ʻōmaʻomaʻo.

He aha ke kaʻina hana kemika holoʻokoʻa e hoʻololi ai i ka ʻōmaʻomaʻo hua manu ke ʻai nui?

Hana ʻia kekahi mau kaʻina biochemical maikaʻi ma mua o ka hiki ʻana o ka hao me ka sulfur e hoʻohuli i ka ʻōmaʻomaʻo hua manu.

E hele kāua ma luna o lākou i kēlā me kēia pae.

ʻO ka hao i loko o ka hua manu

He 2.7% ka hao i loko o ka hua moa moa, he meaʻai koʻikoʻi no ka embryo. ʻO 95% o ka hao i hoʻopaʻa ʻia i ka phosvitin, kahi pūmua i loko o ka hua manu.

Ke hoʻomaka ka embryo e ulu, ulu nā kīʻaha koko i loko o ka yolk e kiʻi i nā meaʻai.

Aia i ke koko ke koko ʻulaʻula e hoʻohana ana i ka hao e lawe i ka oxygen i ka moa e ulu ana.

ʻO ka moa i hānau ʻole ʻia e hanu maoli ana i ka oxygen i loko o ka hua. Ke hele mai nei ka oxygen ma nā pores liʻiliʻi o ka ʻili hua. ʻOi aku ka nui o ka 7000 pores o ka hua moa maʻamau no ka oxygen e hele ai.

Sulfur i loko o ka Egg White

Ua ʻike mākou a pau i ka sulfur no ka mea ʻo ia wale nō ke kuleana o ka ʻala o nā hua pala.

Noho ka hua keʻokeʻo a puni ka yolk ma ke ʻano he papa pale e pepehi ai i ka maʻi bacteria e komo mai ana. Hoʻopiha ʻia i ka wai a me nā protein. ʻOi aku ma mua o ka hapalua o ka hua keʻokeʻo i loko o ka protein ovalbumin, he pūmua i loaʻa nā pūʻulu sulfhydryl manuahi me ka sulfur.

Cysteine

ʻO nā pūmua hua manu nā kaulahao lōʻihi o nā waikawa amino. ʻO ka hapa nui o ka sulfur i loko o nā hua moa aia i loko o ka amino acid methionine pono, kahi precursor o ka cysteine ​​amino acid.

I loko o ke kanaka, he hana koʻikoʻi ka cysteine ​​i ka ʻeli ʻana o ka waiʻona. Ua kaulana ia i ka makahiki 2020 i ka ʻike ʻana o nā kānaka ʻepekema hiki i ka cysteine ​​ke hōʻoluʻolu i nā hōʻailona hangover pili i ka waiʻona, e like me ka nausea a me ke poʻo. Ho'ōla ka cysteine ​​i loko o nā hua manu i ka hangovers.

Hoʻomāhana i ka Hua

Ke anuanu ka hua, ʻo ka membrane vitelline kahi pale e hoʻokaʻawale i nā kinikona i loko o ka yolk mai ka hua keʻokeʻo. Akā, ke hoʻomaka ʻoe e kuke i ka hua, hiki mai kekahi mau mea kilokilo.

ʻO ka mea mua, hana ka wela i nā protein i loko o ka hua maka a hoʻopaʻa hou kekahi me kekahi. Kapa ʻia kēia kaʻina hana he denaturation a ʻo ia ke kumu e paʻakikī ai ka hua i ka wā e hoʻolapalapa ai.

Ma muli o ka wehe ʻana a pau, hoʻokuʻu ʻia ka sulfur mai nā waikawa amino. Hoʻomaka ia e hana i ka hydrogen sulfide, he kinoea honi e like me nā hua popopo. Laki mākou no ka liʻiliʻi o ke kinoea, a i ʻole, ʻaʻole mākou e ʻai i nā hua manu.

ʻIke mākou a pau i ka hana me ka soda inā waiho mākou i ka lā no ka lōʻihi loa: pakele ke kinoea. Pēlā nō me ka hydrogen sulfide, hoʻāʻo ʻo ia e pakele mai ka hua manu keʻokeʻo. ʻAʻole nui loa nā wahi no ke kinoea e hele ai, no laila e hoʻāʻo e laha i loko o ka ʻōpū hua.

Ke hoʻomehana ʻoe i ka hua i ka lōʻihi a me nā wela kiʻekiʻe, hoʻomaka nā protein phosvitin ikaika i loko o ka yolk e wāwahi i lalo ma o ka hydrolysis. ʻAʻole hiki i ka phosvitin ke paʻa i ka hao, a hoʻokuʻu ʻia ka hao i loko o ka yolk.

Ka hao me ka Sulfur

E hui ana ka hao (Fe) mai ka yolk me ka sulfur (S) mai ka hua keokeo ma ka lihi o ka yolk, kahi e nahaha ai ka membrane vitelline. Ka hopena kemikahana i ka ferrous sulfide(FES).

ʻO ka ferrous sulfide kahi hao sulfide ʻeleʻele ke nānā aku i ka ʻōmaʻomaʻo ke hui pū me ka yolk melemele. ʻO ka hopena hope loa, ʻo ka ʻeleʻele ʻōmaʻomaʻo-ʻeleʻele āu e loaʻa ai i ka hua manu paʻakikī.

Wahi a kekahi mau kumu, ʻo ka ʻōmaʻomaʻo he ferric sulfide, akā he mea paʻa ʻole ia i hana ʻole ʻia ma ke ʻano a palaho i ka ferrous sulfide.

He aha nā mea e hoʻonui ai i ka hopena o ka ʻōmaʻomaʻo o ka hua manu?

E piʻi aʻe ka pilikia o ka ʻōmaʻomaʻo hina-hinahina o ka yolk hua inā:

• moʻa ʻia ka hua ma nā wela kiʻekiʻe loa
• ua wela ka hua no ka manawa lōʻihi
• mālama ʻia ka hua ma mua o ka kuke ʻana
• he kiʻekiʻe ka pH o ka hua manu
• hoʻomoʻa ʻoe i nā hua i loko o ka pā hao

Piʻi ka pH o ka hua i ka wā e ulu ai ka hua. Hiki i ka pH ke hoʻololi i nā waiwai alkaline, me ka waiho ʻana o carbon dioxide i ka hua i loko o kekahi mau lā. Hoʻonui kēia i ka hopena o ka hao o ka yolk me ka sulfur o ka hua keʻokeʻo.

Ma muli o ka hoʻohuli ʻana o ka hao i ka ʻōmaʻomaʻo hua, ʻoi aku ka maikaʻi o ka pale ʻana iā lākou i loko o ka skillet hao.

ʻAʻole pili ka ʻano moa, ka nui o ka hua, ka waihoʻoluʻu hua, a me ka maikaʻi o ka hua i ka ʻōmaʻomaʻo o ka yolk.

Hōʻuluʻulu manaʻo

ʻO ka ʻōmaʻomaʻo hina hina o ka hua manu i loko o nā hua i hoʻolapalapa ʻia ma muli o ka ʻai nui ʻana. Hoʻopili ka wela i ka hao i loko o nā yolks hua me ka sulfur i loko o nā hua keʻokeʻo. He ʻōmaʻomaʻo ke ʻano o ka ferrous sulfide ʻeleʻele ma luna o ka yolk hua melemele.

No ka pale ʻana i ka ʻōmaʻomaʻo ʻōmaʻomaʻo, he kī ia e pale ai i ka hao i loko o ka yolk mai ka hoʻokuʻu ʻana. E hoʻohaʻahaʻa i ka mahana o ka wai a e hōʻoia i ka wela wale nō o ka hua manu i mea e paʻakikī ai. E hoʻomaloʻo koke me ka wai anuanu ma hope o ka kuke ʻana.
