Inyama yehagu ibisoloko iyeyona nto iphambili kwinyama etafileni yabemi, kwaye ngumthombo obalulekileyo weproteni esemgangathweni ophezulu. Kwiminyaka yakutshanje, ukutya okunamandlaukufuya iihaguibisoloko ifuna kakhulu ukukhula, ukuguquka kokutya, ukuncipha kwenyama engenamafutha, umbala okhanyayo wenyama yehagu, incasa engathandekiyo kunye nezinye iingxaki, kwaye inyama yehagu ithambile kwaye inencasa, nto leyo ethandwa luluntu. Ziziphi izinto ezichaphazela incasa yehagu?

1. Iintlobo ngeentlobo

Okwangoku, ii-hydrocarbons, ii-aldehydes, ii-ketones, ii-alcohols, ii-esters, ii-furans, i-pyrazine kunye nezinye izinto eziguquguqukayo zifunyenwe kwihagu. Uninzi lwale nxalenye ziyafana kwiintlobo ezahlukeneyo zenyama, kodwa umxholo wazo wahlukile. Umzekelo, iintlobo zehagu zehagu zinencasa etyebileyo efana neswekile, amafutha kunye neeproteni. Iintlobo zehagu zasekuhlaleni zifuywa ngabantu abasebenzayo belizwe lethu ngokuzalisa ixesha elide kwaye ziibhanki zejini ezixabisekileyo. Sifanele sinikele ngokupheleleyo kwiingenelo zeentlobo zehagu zasekuhlaleni kwaye sikhulise iintlobo zehagu ezinencasa elungileyo.

2. Ubudala kunye nesini

Ukuthamba kwehagu kuyachaphazeleka kubudala behagu. Amantshontsho eehagu, ngenxa yemicu yawo emincinci yemisipha kunye nokudibanisa okuncinci kwezicubu ezidityanisiweyo, atsha kwaye athambile. Ngokukhula kweminyaka, ukudibanisa okuvuthiweyo kwezicubu ezidityanisiweyo kuyakhula kancinci kancinci, kwaye imicu yemisipha iyatyeba, nto leyo ebangela ukuncipha kokuthamba. Ezinye izifundo zibonise ukuba umgangatho wenyama uyaphucuka kancinci kancinci ngokukhula kweminyaka, kodwa uhlala uzinzile emva kweentsuku ezingama-220 ubudala, nto leyo efuna ingqalelo kubudala bokuxhelwa kweehagu kwimveliso. Ukuxhelwa kwangaphambi kwexesha akulungele ukuphucula umgangatho wenyama, kwaye ukuxhelwa emva kwexesha kuya kuchitha iindleko zemveliso kwaye akuyi kuphucula umgangatho wenyama. Umgangatho wehagu awuchaphazeleki kuphela kubudala, kodwa nakwisondo sehagu. Iigranule ze-cross section zemicu yehagu zikhulu, kwaye ziqulathe i-androstenone, i-skatole, i-polyunsaturated fatty acids kunye nezinye izinto ezichaphazela incasa.

3. Ukondla

UkondlaIkakhulu ibandakanya inqanaba lesondlo sokudla, ukwakheka kokutya kunye nolawulo lokutya. Inqanaba lesondlo lokutya yenye yezinto ezichaphazela umgangatho wenyama yehagu. Ukondla ukutya okunamandla aphezulu kunye neproteni ephantsi, inyama yehagu inamafutha amaninzi kunye nomgangatho wenyama ethambileyo; Ukondla ukutya okuneproteni ephezulu kunye namandla aphantsi, inyama incinci kwaye umxholo wamafutha uphantsi; Ii-amino acids ezifana ne-lysine, i-threonine kunye ne-cysteine ​​nazo zinempembelelo enkulu kumgangatho wenyama, ngoko ke kufuneka kunikwe ingqalelo kubungakanani bokongeza kwisabelo. Ukongeza kwinqanaba lezakhamzimba zokutya, ukwakheka kokutya kuya kuchaphazela nomgangatho wehagu. Ukondla umbona omninzi kuya kwenza inyama yehagu ibe mthubi, ikakhulu kuba umbala omthubi embona ufakwe kumafutha ehagu kunye nezicubu zemisipha; I-Thiopropene, i-propylene disulfide, i-allicin, ii-aromatics kunye nezinye izinto ezikukutya kuya kubangela ivumba elikhethekileyo lenyama yehagu kwaye kuchaphazele umgangatho wenyama. Ukongezwa kwe-Eucommia ulmoides leaves extract njenge-feed additive kwi-feed kunokunceda ukwenza i-collagen kunye nokuphucula umgangatho wehagu. Ukongeza, umgangatho wehagu uya kuchaphazela neendlela zokuyitya. Umzekelo, kukho ibala lemidlalo elikhethekileyo leehagu. Ukwandisa inani leehaguukutya okuluhlazakunye nokutya okurhabaxa kunokuphucula umgangatho wenyama yehagu.

4. Ezinye izinto

Izinto ezibangela ukubulawa njengendlela yokuxhela, ixesha lokulinda, ixesha lokuthuthwa, kunye nonyango emva kokufa njengobushushu bedama lokutshisa kunye nendlela yokupheka ziya kuchaphazela umgangatho wehagu. Umzekelo, xa kuthelekiswa noxinzelelo lombane, ukufunxwa yikhabhoni diokside kunokunciphisa kakhulu ukuxhaphaka kwemisipha emhlophe; Ukunciphisa ixesha lokuthuthwa kunye nokwandisa ixesha lokuxhela kunokunciphisa uxinzelelo lweehagu; Ubushushu bedama lokutshisa akulula ukuba bube phezulu kakhulu. Ukuba ubushushu bungaphezulu kwama-60 ℃, ihagu iya kutshiswa ize iqengqwe, nto leyo eya kuchaphazela incasa yehagu.

Ngamafutshane, kwimveliso yokwenyani, kufuneka sikhethe ngokufanelekileyo iintlobo ngeentlobo, siqinise ulawulo lwesayensi lokutya, sinciphise uxinzelelo ngaphambi kokuxhela kunye neminye imiba yokulawula ukuqinisekisa umgangatho wenyama ongcono.
