Nguruve yakagara iri chikamu chikuru chenyama yetafura yevagari, uye inokosha inokosha yeprotein yepamusoro.Mumakore achangopfuura, zvakanyanyakupfuya nguruveyanga ichitsvaga kukura kwekukura, chiyero chekushandura chikafu, nyama yakaonda, ruvara rwakareruka rwenguruve, kuravira kwakashata uye mamwe matambudziko, uye nyama yenguruve inyoro uye inonaka, inofarirwa neveruzhinji.Ndezvipi zvinhu zvinokanganisa kuravira kwenguruve?

1. Zvakasiyana-siyana

Parizvino, mahydrocarboni, aldehydes, ketoni, doro, esters, furans, pyrazine nezvimwe zvinhu zvinopisa zvakaonekwa munguruve.Zvizhinji zvezvikamu izvi zvakafanana mumhando dzakasiyana dzenyama, asi zviri mukati mavo zvakasiyana.Semuenzaniso, nguruve inobereka nyama yenguruve ine yakapfuma flavour precursors senge shuga, mafuta uye mapuroteni.Mhuka dzenguruve dzemunharaunda dzinoberekerwa nevanhu vanoshanda munyika yedu kuburikidza nekubereka kwenguva refu uye inokosha mabhanga ejeni.Tinofanira kupa kutamba kwakazara kune zvakanakira nguruve dzemuno uye kurima hunhu hwenguruve dzine kunaka kwakanaka.

2. Zera uye murume kana mukadzi

Nguruve nyoro inobatwa nezera renguruve.Nguruve, nekuda kwekunaka kwemhasuru fibers uye kushoma kudiki-kusangana kwekubatana kwetishu, kutsva uye kupfava.Nekuwedzera kwezera, iyo yakakura yekubatanidza yekubatanidza tishu zvishoma nezvishoma inowedzera, uye tsandanyama fiber inokora, zvichikonzera kudzikira kwehunyoro.Zvimwe zvidzidzo zvakaratidza kuti hutano hwenyama hunovandudzwa zvishoma nezvishoma nekuwedzera kwezera, asi hunoita kuti huve hwakagadzikana mushure memazuva e220, izvo zvinoda kutariswa kumakore ekuurawa kwenguruve mukugadzira maitiro.Kuuraya nguva isati yakwana hakubatsiri kuvandudza kunaka kwenyama, uye kunonoka kuuraya kunoparadza mari yekugadzira uye hakuzogadzirise kunaka kwenyama.Nguruve yehutano inobatwa kwete chete nezera, asiwo nehove yepabonde.Iyo yemuchinjikwa chikamu granules yeboar muscle fibers yakakura, uye ine androstenone, skatole, polyunsaturated fatty acids uye zvimwe zvinhu zvinokanganisa kunaka.

3. Kudyisa

Kudyisakunyanya zvinosanganisira chiyero chekudya kwekudya, kuumbwa kwechikafu uye kutonga kwekudya.Chiyero chekudya kwekudya ndicho chimwe chezvinhu zvinokanganisa kunaka kwenguruve.Kudyisa kudya kwesimba guru uye mapuroteni mashoma, nyama yenguruve ine mafuta akawanda uye nyama yakapfava;Kudyisa chikafu chine mapuroteni akakwirira uye simba shoma, nyama yakagadzikana uye mafuta ari pasi;Iyo amino acids yakadai selysine, threonine uye cysteine ​​zvakare ine simba guru pamhando yenyama, saka kutarisisa kunofanirwa kubhadharwa kune huwandu hwekuwedzera muchikamu.Pamusoro pehuwandu hwehupfu hwekudya, kuumbwa kwekudya kuchakanganisawo hutano hwenguruve.Kudyisa chibage chakawandisa kuchaita yenguruve yero, kunyanya nekuti iyo yero pigment muchibage inoiswa mumafuta enguruve uye tsandanyama tishu;Thiopropene, propylene disulfide, allicin, aromatics uye zvimwe zvinhu zviri mukudya zvinokonzeresa kunhuhwirira kwenguruve uye kukanganisa kunaka kwenyama.Kuwedzerwa kweEucommia ulmoides mashizha anobvisa sekuwedzera kwekudya mukudya kunogona kubatsira kugadzira collagen uye kunatsiridza mhando yenguruve.Mukuwedzera, hutano hwenguruve huchabatwawo nenzira dzekudya.Semuenzaniso, kune nzvimbo yakakosha yemitambo yenguruve.Kuwedzera huwandu hwegreen feeduye coarse feed inogona kuvandudza kunaka kwenguruve.

4. Zvimwe zvinhu

Preslaughter zvinhu zvakadai sekuuraya nzira, nguva yekumirira, nguva yekufambisa, uye post-mortem kurapwa senge scalding dziva tembiricha uye kubika nzira kuchakanganisa nyama yenguruve kunaka.Somuenzaniso, kana ichienzaniswa nemagetsi, carbon dioxide asphyxiation inogona kuderedza zvakanyanya kuitika kwetsandanyama yakachena;Kuderedza nguva yekufambisa uye kuwedzera nguva yekuuraya kunogona kuderedza kushungurudzika kwenguruve;Tembiricha ye scalding dziva haisi nyore kuve yakakwira zvakanyanya.Kana tembiricha yakapfuura 60 ℃, nyama yenguruve inozopiswa uye yakakungurutswa, izvo zvinokanganisa kuravira kwenguruve.

Kupfupisa, mukugadzirwa chaiko, isu tinofanirwa kusarudza zvine musoro mhando, kusimbisa sainzi yekudyisa manejimendi, kuderedza pre slaughter stress uye zvimwe zvinhu zvemutemo kuti tive nechokwadi chemhando yepamusoro yenyama.
