L-Selenomethionine: Mbadwo Watsopano wa Selenium Wachilengedwe Wopezeka mu Zakudya za Zinyama

Mu ulimi wa ziweto wamakono, njira zopangira chakudya zikuchulukirachulukira, ndipo kuwonjezera zinthu zina si chinthu chatsopano. Koma pankhani ya selenium, mwina mudamvapo za sodium selenite kapena yisiti ya selenium, koma mwina simukudziwa bwino mankhwala omwe akuchulukirachulukira kuchokera kwa opanga chakudya: L-selenomethionine.

Mwachidule, L-selenomethionine ndi gwero la selenium yachilengedwe–selenoamino acid yomwe imapezeka mwachilengedwe yomwe imapezeka m'zomera ndi tirigu wa chakudya, komwe selenium imalumikizidwa mu mawonekedwe achilengedwe. Poyerekeza ndi selenium yachikhalidwe yopanda organic (monga sodium selenite), L-selenomethionine imapereka zabwino zitatu zazikulu: kuopsa kochepa, kuipitsidwa kochepa kwa chilengedwe, komanso kupezeka kwa bioavailability kokwera kwambiri. Chifukwa cha maubwino awa, malamulo padziko lonse lapansi achepetsa pang'onopang'ono zoletsa kugwiritsa ntchito L-selenomethionine mu chakudya, zomwe zimapangitsa kuti ikhale njira yatsopano yodalirika pazakudya za nyama.

Ndiye n’chiyani chimapangitsa kuti L-selenomethionine ikhale yapadera? Kodi ingathandize bwanji ziweto?'Yang'anani bwino.

1. Kodi n'chiyaniL-Selenomethionine?

Ngati simukudziwa bwino za biochemistry, apa'fanizo losavuta: Methionine ndi amino acid yofunika kwambiri mwa nyama. L-selenomethionine imapangidwa mwa kusintha atomu ya sulfure mu methionine ndi atomu ya selenium. Kusintha kumeneku komwe kumawoneka kosavuta kumaipatsa mawonekedwe apadera.

Mu chilengedwe, selenium imapezeka makamaka m'njira ziwiri.–Zosakaniza ndi zachilengedwe. Selenium yopanda chilengedwe imaphatikizapo sodium selenite ndi selenate, pomwe selenium yachilengedwe imatanthauza makamaka selenoamino acids monga selenomethionine ndi selenocystine. L-selenomethionine ndiye mtundu waukulu wa selenium yachilengedwe womwe umapezeka mu yisiti ya selenium, komanso gwero lalikulu la selenium yachilengedwe m'zomera ndi tirigu.

L-selenomethionine ili ndi luso lapadera: imatha kuyamwa mwachindunji ndi nyama ndikuyikidwa mkati mwa mapuloteni a minofu, chiwindi, ndi minofu ina, ndikupanga dziwe losungira selenium m'thupi. Mosiyana ndi zimenezi, mitundu ina ya selenium (kuphatikizapo selenium yopanda organic ndi zina za organic selenium) pamapeto pake imachepetsedwa kukhala hydrogen selenide, ndipo yochulukirapo imatulutsidwa ndipo singathe kusungidwa. Kafukufuku wasonyeza kuti nkhuku zikapatsidwa sodium selenite, kuchuluka kwa selenium komwe kumatulutsidwa kumakhala kokwera katatu kuposa komwe kumaperekedwa L-selenomethionine.–kutsimikizira kuti selenium yopanda organic ndi yovuta kusunga m'thupi la nyama.

Ndi izi ndendende“zosungidwa"khalidwe lomwe limapangitsa kuti L-selenomethionine ikhale yosiyana kwambiri ndi magwero a selenium.

2. Ubwino Waukulu waL-Selenomethionine

2.1 Kupezeka Kwambiri kwa Bioavailability

Anthu ambiri asayansi amavomereza kuti selenium imakhala ndi bioavailability yapamwamba kwambiri pakati pa mankhwala a selenium achilengedwe. Nyama zimayamwa selenomethionine bwino kwambiri kuposa selenium yopanda organic, zomwe zikutanthauza kuti selenium yomwe imawonjezeredwa ku chakudya imagwiritsidwa ntchito bwino m'malo motulutsidwa mu ndowe.

2.2 Chitetezo Chamthupi Chowonjezereka ndi Kukana Kupsinjika Maganizo

Ulimi wa ziweto wamakono umaika ziweto pachiwopsezo chowonjezereka cha zinthu zomwe zimawononga chilengedwe (monga kutentha kwambiri, nyumba zokhala ndi anthu ambiri, mayendedwe). Zikakhala ndi nkhawa, ziweto zimapanga ma free radicals ambiri, zomwe zimapangitsa kuti maselo awonongeke komanso minofu isamagwire bwino ntchito. L-selenomethionine ili ndi mphamvu yoteteza ku ma antioxidants, zomwe zimapangitsa kuti ma enzyme ofunikira a antioxidant monga glutathione peroxidase agwire ntchito, zomwe zimathandiza nyama kuchotsa ma free radicals komanso kulimbikitsa chitetezo cha mthupi komanso kupirira kupsinjika.

2.3 Mbiri Yachitetezo Chapamwamba

Poyerekeza ndi selenium yopanda organic, selenium yachilengedwe ndi yopanda poizoni komanso yoteteza chilengedwe. EFSA FEEDAP Panel inapeza kuti L-selenomethionine ndi yotetezeka kwa mitundu yonse ya nyama ngati selenium yonse yomwe ili mu chakudya sichidutsa malire ovomerezeka, ndipo sichibweretsa chiopsezo china ku chilengedwe.

3. Kugwiritsa Ntchito ndi Zotsatirapo pa Kupanga Zinyama

3.1 Ubwino wa Nkhuku Zoyikira ndi Mazira

L-selenomethionineKafukufuku akusonyeza kuti selenomethionine sikuti imawonjezera selenium m'mazira okha komanso imapangitsanso kuti mazira azikhala abwino komanso imawonjezera mphamvu ya antioxidant komanso chitetezo cha chitetezo cha nkhuku zobereketsa. Nkhuku zobereketsa nkhuku zikapatsidwa L-selenomethionine, mphamvu ya antioxidant ya mazira a ana awo imakulanso.–kusonyeza zotsatira za m'badwo kuchokera kwa mayi kupita kwa ana.

3.2 Nkhumba

Pakupanga nkhumba, L-selenomethionine imagwiranso ntchito bwino. Kafukufuku akutsimikizira kuti selenomethionine yazakudya imawonjezera mphamvu ya plasma ndi minofu ya antioxidant pakumaliza nkhumba ndikuchepetsa zizindikiro za kuwonongeka kwa okosijeni. Kugwiritsa ntchito kovomerezeka kwa L-selenomethionine kwakulitsidwa kwa ana a nkhumba olekanitsidwa ndi nkhuku zoyamwitsa, ndi mulingo wowonjezera wosapitirira 0.20 mg/kg (monga selenium element) mu chakudya chonse cha ana a nkhumba olekanitsidwa.

3.3 Ulimi wa m'madzi

Mu ulimi wa nsomba, L-selenomethionine yapita patsogolo kwambiri. Kafukufuku akusonyeza kuti kuwonjezera 0.15 mg/kg ya selenomethionine kuti idyetse nsomba zachikasu kumathandiza kuti nsomba za m’madzi zikule bwino komanso kuti minofu ikhale ndi mphamvu yoteteza ku matenda a kusowa kwa zakudya m’thupi. Mu 2025, China yachita izi.'Unduna wa Zaulimi ndi Zakumidzi unawonjezera kugwiritsa ntchito L-selenomethionine pa nsomba za m'madzi oyera, ndi mlingo wovomerezeka wowonjezera wa 0.4 mg/kg (kutengera 88% ya zinthu zouma, monga selenium element) mu chakudya chonse cha nsomba za m'madzi oyera.

3.4 Nyama zolusa

Kwa nyama zoweta monga ng'ombe zamkaka, selenium yachilengedwe imathandizanso kuti pakhale zokolola zambiri, imalimbitsa chitetezo cha mthupi, imakulitsa ubwino wa nyama, komanso imawonjezera mphamvu yobereka. Chilengezo cha 2025 chinavomerezanso kugwiritsa ntchito L-selenomethionine m'ng'ombe zamkaka zoyamwitsa, ndi mlingo wovomerezeka wa 0.3 mg/kg mu chakudya chonse chosakanikirana.

4. Malamulo Padziko Lonse“Kuwala Kobiriwira"

Mzaka zaposachedwa,L-selenomethionineyalandira kuvomerezedwa mwalamulo padziko lonse lapansi.

Ku China, Unduna wa Zaulimi ndi Zakumidzi unakulitsa kuchuluka kwa L-selenomethionine mu 2022 kuti iphatikizepo ana a nkhumba olekanitsidwa ndi nkhuku zoyamwitsa, ndi malire apamwamba a selenium a 0.50 mg/kg mu chakudya chonse. Mu 2025, kuchuluka kwa selenium kunakulitsidwanso ku nsomba za m'madzi oyera ndi ng'ombe za mkaka zoyamwitsa. Kuchepetsa malamulo kumeneku kumapatsa opanga chakudya kusinthasintha kwakukulu.

Padziko lonse lapansi, mu Meyi 2025, bungwe la US FDA linavomereza zinc-L-selenomethionine ngati gwero la selenium m'zakudya za nkhuku, kuyambira pa Meyi 19, 2025. Bungwe la European Food Safety Authority (EFSA) lawunikanso mobwerezabwereza ndikutsimikizira chitetezo cha zinc-L-selenomethionine kwa nyama zonse, ogula, ndi chilengedwe.

5. SankhaniL-SelenomethionineKuti Ziweto Zizidya Zakudya Zabwino

Kuchokera pa zomwe zili pamwambapa, n'zoonekeratu chifukwa chake L-selenomethionine ikukondedwa ndi opanga zakudya zambiri.–Zimathetsa vuto lalikulu la magwero a selenium achikhalidwe: kugwiritsa ntchito mochepa komanso kulephera kusungidwa.

ChifukwaL-selenomethionineZikhoza kulowetsedwa mu mapuloteni a nyama, zomwe zimapangitsa kuti selenium ikhale m'thupi, nyama zimakhala ndi selenium yokwanira kuti zisunge ntchito yabwino ya antioxidant ngakhale zitakhala ndi nkhawa (monga kuchepetsa kudya chakudya nthawi yotentha). Komanso, L-selenomethionine yopangidwa yokha, yokhala ndi amino acid imodzi, imapereka bioavailability yochuluka kuposa zinthu zosakanikirana monga yisiti yolemeretsedwa ndi selenium.

Sustar, yemwe ali ndi zaka zoposa 35 akugwira ntchito yodyetsa nyama, wadzipereka kupereka zinthu zabwino kwambiri zotsalira komanso zowonjezera chakudya kwa opanga chakudya padziko lonse lapansi. Zogulitsa zathu zimaphatikizapo zinthu zopanda organic, zinthu zachilengedwe zotsalira, ndi zinthu zosakanikirana ndi nyama, ndipo mchere wathu waung'ono wa peptide chelated ndi womwe ukutsogolera makampaniwa. Tili ndi ziphaso za ISO, GMP, ndi FAMI-QS ndipo takhazikitsa mgwirizano wokhazikika komanso wanthawi yayitali ndi makampani otsogola padziko lonse lapansi monga Chia Tai Group, Cargill, DSM, ADM, Nutreco, ndi New Hope.

Mu gawo la selenium yachilengedwe, Sustar'Zogulitsa za L-selenomethionine zimagwirizana kwambiri ndi miyezo ya chakudya. Opanga chakudya ndi makasitomala a ulimi ndi olandiridwa kuti atilankhule kuti tifunse mafunso ndi kukambirana zaukadaulo.

Nkhaniyi yachokera pa kafukufuku wa anthu onse ndi zambiri zamakampani kuti ziphunzire komanso zigwiritsidwe ntchito pongofuna kudziwa zambiri. Chonde tsatirani malamulo am'deralo ndi malangizo aukadaulo ogwiritsira ntchito zinthu.
