I-L-Selenomethionine: Umthombo Wesizukulwane Esisha Selenium Engokwemvelo Ekudleni Kwezilwane

Ekufuyeni kwemfuyo kwanamuhla, ukwakheka kokudla kuya ngokuya kucwengwa, futhi ukwengeza izakhi zokulandelela akuyona into entsha. Kodwa uma kukhulunywa nge-selenium, kungenzeka ukuthi uke wezwa nge-sodium selenite noma i-selenium yeast, kodwa kungenzeka ukuthi awujwayelene nenhlanganisela ethola ukunakwa okwandayo kubakhiqizi bokudla: i-L-selenomethionine.

Kalula nje, i-L-selenomethionine ingumthombo we-selenium we-organic–i-selenoamino acid etholakala ngokwemvelo ezitshalweni nasezinhlamvini zokudla, lapho i-selenium iboshelwe khona ngendlela ephilayo. Uma kuqhathaniswa ne-selenium yendabuko engakhiqizi izinto eziphilayo (njenge-sodium selenite), i-L-selenomethionine inikeza izinzuzo ezintathu ezinkulu: ubuthi obuphansi, ukungcola okuncane kwemvelo, kanye nokutholakala kwezinto eziphilayo okuphezulu kakhulu. Ngenxa yalezi zinzuzo, imithethonqubo emhlabeni wonke iye yanciphisa kancane kancane imikhawulo ekusetshenzisweni kwe-L-selenomethionine ekudleni, okwenza kube inketho entsha ethembisayo ekudleni kwezilwane.

Ngakho-ke yini eyenza i-L-selenomethionine ivelele? Iyiphi inzuzo yangempela engayiletha ekukhiqizweni kwemfuyo? Ake sithi'bheka ngokujulile.

1. KuyiniI-L-Selenomethionine?

Uma ungajwayelene ne-biochemistry, lapha'Isifaniso esilula: I-Methionine iyi-amino acid ebalulekile ezilwaneni. I-L-selenomethionine yakhiwa ngokufaka esikhundleni se-athomu yesulfure ku-methionine nge-athomu ye-selenium. Lokhu kufakwa esikhundleni okubonakala kulula kuyinika izakhiwo ezihlukile.

Emvelweni, i-selenium ikhona ikakhulukazi ngezindlela ezimbili.–Izinto ezingaphili kanye nezinto eziphilayo. I-selenium engaphili ihlanganisa i-sodium selenite kanye ne-selenate, kuyilapho i-selenium engaphili ibhekisela kakhulu kuma-selenoamino acid njenge-selenomethionine kanye ne-selenocystine. I-L-selenomethionine iwuhlobo oluyinhloko lwe-selenium engaphili olutholakala kwimvubelo ye-selenium, kanye nomthombo we-selenium engaphili oyinhloko ezitshalweni nasezinhlamvini.

I-L-selenomethionine inekhono eliyingqayizivele: ingamuncwa ngqo yizilwane futhi ifakwe iphelele kumaprotheni esakhiwo semisipha, isibindi, nezinye izicubu, yakha ichibi lokugcina i-selenium emzimbeni. Ngokuphambene nalokho, ezinye izinhlobo ze-selenium (kufaka phakathi i-selenium engaphili kanye nezinye izinto eziphilayo ze-selenium) ekugcineni zincishiswa zibe yi-hydrogen selenide, lapho noma yikuphi okungaphezulu kukhishwa futhi kungenakugcinwa. Izifundo zibonise ukuthi lapho ama-broiler ephakelwa i-sodium selenite, izinga lokukhishwa kwe-selenium liphakeme cishe kathathu kunalapho kunikezwa i-L-selenomethionine.–okuqinisekisa ukuthi i-selenium engaphili kunzima ukuyigcina emzimbeni wesilwane.

Yilokhu kanye"okugcinekayo"isici esenza i-L-selenomethionine ivelele phakathi kwemithombo ye-selenium.

2. Izinzuzo Eziyinhloko zeI-L-Selenomethionine

2.1 Ukutholakala Kwezinto Eziphilayo Okuphezulu Kakhulu

Umphakathi wesayensi uvame ukuvuma ukuthi i-selenomethionine inokutholakala okuphezulu kakhulu kwezinto eziphilayo phakathi kwamakhemikhali e-selenium ephilayo. Izilwane zimunca i-selenomethionine kangcono kakhulu kune-selenium engaphili, okusho ukuthi i-selenium eyongezwa ekudleni isetshenziswa kahle kakhulu kunokuba ikhishwe emqubeni.

2.2 Ukuthuthukiswa Kokuzivikela Emzimbeni Nokumelana Nokucindezeleka

Ukufuya izilwane kwanamuhla kuveza izilwane ezinkingeni zemvelo ezikhulayo (isib. amazinga okushisa aphezulu, indawo yokuhlala enabantu abaningi, ezokuthutha). Ngaphansi kokucindezeleka, izilwane zikhiqiza inani elikhulu lama-free radicals, okuholela ekulimaleni kwamangqamuzana kanye nokusebenza kwezicubu okungasebenzi kahle. I-L-selenomethionine inomsebenzi oqinile we-antioxidant, okwandisa umsebenzi wama-enzyme abalulekile e-antioxidant njenge-glutathione peroxidase, okusiza izilwane ukuqeda ama-free radicals futhi kukhulisa ukuzivikela komzimba kanye nokuqina kokucindezeleka.

2.3 Iphrofayili Yokuphepha Ephakeme

Uma kuqhathaniswa ne-selenium engakhiqizi, i-selenium ephilayo ayinabo ubuthi obuncane futhi inobungani nemvelo. Iphaneli ye-EFSA FEEDAP iphethe ngokuthi i-L-selenomethionine iphephile kuzo zonke izinhlobo zezilwane uma nje i-selenium iyonke ekudleni ingadluli umkhawulo ophezulu osemthethweni, nokuthi ayibeki ingozi eyengeziwe emvelweni.

3. Ukusetshenziswa kanye Nemiphumela Ekukhiqizweni Kwezilwane

3.1 Izinkukhu Ezizalelayo Nezinga Lamaqanda

I-L-selenomethionineKuye kwafundwa kabanzi ezinkukhuni ezizalayo. Ucwaningo lubonisa ukuthi i-selenomethionine ayigcini nje ngokwandisa kakhulu okuqukethwe kwe-selenium emaqandeni kodwa futhi ithuthukisa ikhwalithi yamaqanda futhi ithuthukisa amandla okulwa ne-antioxidant kanye nokuvikeleka kwezinkukhu ezizalayo. Lapho izinkukhu ezizalayo ze-broiler zinikwa i-L-selenomethionine, amandla okulwa ne-antioxidant ezingane zazo nawo ayathuthuka.–okubonisa umphumela we-transgeneration kusukela kumama kuya enzalweni.

3.2 Izingulube

Ekukhiqizweni kwezingulube, i-L-selenomethionine nayo isebenza kahle. Izifundo ziqinisekisa ukuthi i-selenomethionine yokudla ikhulisa amandla e-plasma kanye nezicubu ze-antioxidant ekuqedeni izingulube futhi inciphisa izimpawu zomonakalo we-oxidative. Ukusetshenziswa okuvunyelwe kwe-L-selenomethionine kunwetshiwe ezingulubeni ezilunyulwe kanye nezinkukhu ezizalela amaqanda, ngezinga elinconywayo lokwengeza elingekho ngaphezu kuka-0.20 mg/kg (njengesakhi se-selenium) ekudleni okuphelele kwezingulube ezilunyulwe.

3.3 Ukufuywa Kwezinhlanzi

Ekufuyweni kwezinhlanzi, i-L-selenomethionine nayo ifinyelele intuthuko ebalulekile. Ucwaningo lubonisa ukuthi ukwengeza u-0.15 mg/kg we-selenomethionine ukuze kondliwe kuthuthukisa ukusebenza kokukhula kwe-yellow catfish ngenkathi kuthuthukisa amandla okulwa ne-antioxidant emisipha. Ngo-2025, eShayina'UMnyango Wezolimo Nezindaba Zasemakhaya wandise ukusetshenziswa kwe-L-selenomethionine ezinhlanzini zamanzi ahlanzekile, ngezinga elinconywayo lokwengeza elingu-0.4 mg/kg (ngokusekelwe ku-88% wezinto ezomile, njenge-selenium element) ekudleni okuphelele kwezinhlanzi zamanzi ahlanzekile.

3.4 Izilwane ezidla inyama

Kwabafuyi bezinkomo ezifana nezinkomo zobisi, i-selenium ephilayo nayo ithuthukisa umkhiqizo, ithuthukisa amasosha omzimba, ithuthukisa ikhwalithi yenyama, futhi ikhulisa ukusebenza kokuzala. Isimemezelo sango-2025 siphinde savuma ukusetshenziswa kwe-L-selenomethionine ezinkomeni zobisi ezincelisayo, ngezinga elinconywayo lokwengeza elingu-0.3 mg/kg kwisilinganiso esihlanganisiwe esiphelele.

4. Ukulawulwa Komhlaba Wonke"Izibani Eziluhlaza"

Eminyakeni yakamuva,I-L-selenomethionineiye yathola ukuqashelwa okusemthethweni okwandayo emhlabeni jikelele.

E-China, uMnyango Wezolimo Nezindaba Zasemakhaya wandisa ububanzi be-L-selenomethionine ngo-2022 ukuze kufakwe amaphuphu ezingulube ezilunyuliwe kanye nezinkukhu ezizalela amaqanda, ngomkhawulo ophezulu we-selenium ongu-0.50 mg/kg ekudleni okuphelele. Ngo-2025, ububanzi bandiswa kakhulu ezinhlanzini zamanzi ahlanzekile kanye nezinkomo zobisi ezincelisayo. Lokhu kukhululeka kwenqubomgomo kunikeza abakhiqizi bokudla ukuguquguquka okukhulu kokwakheka.

Emhlabeni jikelele, ngoMeyi 2025, i-US FDA igunyaze i-zinc-L-selenomethionine njengomthombo wokudla okunomsoco we-selenium ekudleni kwenkukhu, kusukela ngoMeyi 19, 2025. I-European Food Safety Authority (EFSA) iphinde yahlola futhi yaqinisekisa ngokuphindaphindiwe ukuphepha kwe-zinc-L-selenomethionine kuzo zonke izilwane, abathengi, kanye nemvelo.

5. KhethaI-L-SelenomethionineUkuze Kutholakale Ukudla Okungcono Kwezilwane

Kusukela kulwazi olungenhla, kusobala ukuthi kungani i-L-selenomethionine ithola ukuthandwa phakathi kwabakhiqizi abaningi bokuphakelayo–Ixazulula inkinga eyinhloko yemithombo ye-selenium yendabuko: ukusetshenziswa okuphansi kanye nokungakwazi ukugcinwa.

NgobaI-L-selenomethionineingafakwa ingaphelele kumaprotheni ezicutshini zezilwane, yakha inqolobane ye-selenium emzimbeni, izilwane zinezitolo ezanele ze-selenium ukuze zigcine ukusebenza okuvamile kwe-antioxidant ngisho nangaphansi kwezimo zokucindezeleka (isb., ukudla okuncishisiwe ngesikhathi sezulu esishisayo). Ngaphezu kwalokho, i-L-selenomethionine yokwenziwa emsulwa, enesimo sayo se-amino acid eyodwa, inikeza ukutholakala okuphezulu kwe-bioavailability kunemithombo exubile njengemvubelo ecebile nge-selenium.

I-Sustar, enolwazi olungaphezu kweminyaka engama-35 kwezokudla kwezilwane, izibophezele ekuhlinzekeni izakhi zokulandelela ezisezingeni eliphezulu kanye nezithasiselo zokudla ezisebenzayo kubakhiqizi bokudla emhlabeni jikelele. Uhla lwemikhiqizo yethu luhlanganisa izakhi zokulandelela ezingaphili, izakhi zokulandelela eziphilayo, kanye nama-premixes ezilwane, kanye namaminerali ethu amancane aqukethe i-peptide chelated ahola imboni. Sinezitifiketi ze-ISO, GMP, kanye ne-FAMI-QS futhi sisungule ubudlelwano besikhathi eside nobuzinzile nezinkampani zokudla ezihamba phambili emhlabeni njenge-Chia Tai Group, Cargill, DSM, ADM, Nutreco, kanye ne-New Hope.

Emkhakheni we-selenium ephilayo, i-Sustar'Imikhiqizo ye-s L-selenomethionine ihambisana ngokuqinile nezindinganiso zezinga lokuphakela. Abakhiqizi bokuphakelayo kanye namakhasimende ezolimo bamukelekile ukuxhumana nathi ukuze bathole imibuzo kanye nezingxoxo zobuchwepheshe.

Lesi sihloko sisekelwe ocwaningweni lomphakathi kanye nolwazi lwemboni ngezinhloso zokufunda kanye nezinkomba kuphela. Sicela ulandele imithetho yendawo kanye nesiqondiso sobuchwepheshe sokusetshenziswa komkhiqizo.
