Tendons, Ligaments, Silverskin ndi zina
Ndimalemba zambiri za zakudya zophika nyama, ndipo nthawi zina ndimadzipangitsa kuti ndizitanthauza kuti ndi chinthu chimodzi chokha. Pali mitundu yambiri ya zida zogwiritsira ntchito mu nyama.
Pali mtundu wowoneka bwino, monga tendons, womwe umagwirizanitsa minofu ndi mafupa; ndi mitsempha, yomwe imagwirizanitsa mafupa kwa wina ndi mzake.
Ndiye pali mapepala a white fibrous, omwe amatchedwa silverkin, omwe amazungulira minofu yonse.
Pomalizira pake, minofu ya minofu imamangidwanso m'matumbo, ngakhale kuti ndi osawonekera.
Collagen Vs. Elastin
Mankhwalawa amatha kugwira ntchito zosiyanasiyana, amakhalanso ndi zipangizo zosiyanasiyana zomwe zimakhala zosiyana ngati zophika.
Pali elastin, mapuloteni omwe amapanga silverskin ndi ligaments. Izi ndizo zinthu zomwe mumaganiza ngati gristle.
Ziribe kanthu momwe izo zophika, elastin idzakhala yotentha ndi rubbery. Chinthu chabwino kwambiri chomwe mungachite ndicho kuchotsa zochuluka ngati n'zotheka musanaphike.
Ndiyeno pali puloteni yotchedwa collagen. Kuti tipeze tifunikira kufufuza maselo omwe amapanga nyama yokha.
Nyama imapangidwa ndi maselo autali otchedwa fibers, ndipo minofu ya minofu iliyonse imakulungidwa mu chikho cha collagen.
Mankhwalawa amagawidwa pamodzi m'mitolo, ndipo mtolo uliwonse umakulungidwa mu khola la collagen. Ngakhale maselo amtundu waumunthu (fibers) ndi ofooka kwambiri kuti asawone, ndi matumba awa omwe timazisiyanitsa ngati nyama ya nyama.
Ngati munayamba mwawonapo njira yomwe idakulamulirani kudula nyama pa tirigu, matumba amenewa ndi tirigu omwe mukukumana nawo.
Ntchito ya tizirombo timeneti ndikutulutsa mafupa pamene minofu ikugwirizanitsa, choncho amafunika kukhala olimba. Ndipo ntchito yambiri yomwe minofu imachita (ngati minofu miyendo ndi mapewa), zimakhala zovuta kwambiri kuti ziphuphu zikhale zolimba.
Mitundu kuzungulira kumbuyo ndi nthiti, zomwe zimakhala zochepa zolimbitsa thupi, ziri ndi zochepa za mtundu uwu wa ziwalo zojambulidwa mwa iwo, ndicho chifukwa chake mwachibadwa mwachibadwa.
Mofanana ndi elastin, collagen ndi wovuta. Ngati mutayesa kudya chidutswa cha ng'ombe yochuluka, ikhoza kukhala yosavuta kwambiri, chifukwa makola a collagen omwe ali pafupi ndi mitsempha yonseyo imakhala yosasunthika.
Koma mosiyana ndi elastin, collagen ikhoza kuchepetsedwa ngati itaphika m'njira yoyenera.
Kulowera Kuphika: Chinsinsi Chotsegula Collagen
Kutenthedwa pakati pa 160 ° mpaka 205 ° F, collagen iyamba kuyamba kusungunuka. Chimachitika ndi chakuti collagen imatsikira pansi ndikusanduka gelatin, yomwe ndi yofewa komanso yosavuta.
Izi sizichitika pomwepo - inde, zingatenge maola angapo. Mfungulo ndikuteteza mkati mwa 160 ° mpaka 205 ° F, zomwe zimakhala zosavuta kuziphika pakuphika mu madzi, omwe ndi njira yodziwika ngati kulimba .
Mukhozanso kuchita izi mwa kusuta fodya kapena njuchi, koma zimatengera luso komanso chidwi. Poyerekezera, kukongoletsa ndibwino kwambiri.
Kuphika nyama kufika 160 ° F kapena kupitirira kumapangitsa kuti minofu ikhale yolimba komanso youma. Mukudziwa izi ngati munakhalapo ndi steak yomwe yophikidwa bwino . Koma kudula kwa nyama zomwe timagwiritsira ntchito steaks sizikhala ndi collagen wambiri, chifukwa chake akhoza kuphika mofulumira kwambiri, kutentha kwa mkati osakwana 140 ° F, komabe ndi wachifundo.
Gelatin Imapangitsa Nyama Imodzi ndi Succulent
Koma ndi kudulidwa kolemera kwa nyama, monga momwe minofu imakhalira yolimba ndi youma, collagen yomwe ili pafupi ndi minofu imayamba kusungunuka, kuphimba minofu ndi gelatin, kupatsa nyama kukhala yonyowa ndi yokongola m'kamwa mwako.
Kuonjezera apo, matumbawo amayamba kumasulidwa kamodzi pamene zikhomo zomwe zikuwagwirizanitsa zimachepa. Choncho, ngakhale kuti minofu imakhala yolimba komanso yowuma, nyama yokhayo idzawoneka yokoma komanso yokoma.
Kachiwiri, izi ndi truer ya kudulidwa kolemera kwa nyama monga nyama chuck , kuposa nthiti kapena nthiti yayitali .
Njira ina yochepetsera kupweteka kwa nyama ndiyo kupweteka mitsempha ya collagen pogwiritsa ntchito nyama ya nyama. Izi zimathandiza nyama kuti iphike mwamsanga. Mosiyana ndi zikhulupiriro zambiri, komabe kusamba sikumakonda nyama .
Zochitika zina, zomwe zimachitika pamene nyama imawongolera pang'onopang'ono ndikuti mafuta mkati ndi pakati pa minofu amathanso kumeta ndi kuvala minofu. Izi zimapangitsa kuti zitha kuwonetsetsa kuti zakudya zowonongeka zimakhala bwino.
Momwemo, mutha kudula nyama zowirira kumbuyo kwa nyama, monga rump roast (mwachitsanzo pansi ponse), ndipo collagen idzawonongeka. Koma chifukwa nkhumba zowombeka ndi zowonda kwambiri kuposa ng'ombe ya chuck, braised rump roast sizingakhale zokoma ngati golide wodetsedwa 7 .
Zina Zopangira Collagen
Ndinalongosola kusiyana pakati pa tendons ndi ligaments kale, ndipo mochititsa chidwi, mavitoni amapezeka kuti ndi okwera kwambiri mu collagen.
Ngati mudakhala ndi msuzi wamatoni wambiri, umene umaperekedwa ku malo odyera a ku Vietnam, mumadziwa momwe gelatinous yokhala ndi mchere wamakhalidwe abwino, komanso momwe zimakhutira msuzi wa gelatin.
Potsirizira pake, ngakhale kuti sizimagwirizanitsa pokhapokha, tizilombo toyambitsa matenda ndi gwero lina la collagen. Mukamang'onongeka, katsabola kamene kamakhala m'mapfupa kamasanduka gelatin, kamene kamapangitsa thupi losaneneka ku masitolo ndi kudya .
Mafupa a nyama zinyama ali ndi khungu lotchedwa cartilage, lomwe potsirizira pake limatembenukira ku fupa ngati mibadwo ya zinyama. Ichi ndi chifukwa chake mafupa amatetezedwa makamaka popanga katundu.
Mazira a nkhuku ndi pafupifupi karotila, ndipo amawapangitsa kukhala abwino kwambiri popanga nkhuku .
