L-Selenomethionine: Isoko nshya ya selenium y'umwimerere mu mirire y'inyamaswa

Mu bworozi bwa none, ingano y'ibiryo by'amatungo irimo kugenda irushaho kunozwa, kandi inyongeramusaruro si ikintu gishya. Ariko ku bijyanye na selenium, ushobora kuba warumvise ibya selenite ya sodium cyangwa umusemburo wa selenium, nyamara ushobora kuba utazi ikintu kirimo kwitabwaho n'abakora ibiryo by'amatungo: L-selenomethionine.

Mu magambo make, L-selenomethionine ni isoko ya selenium y’umwimerere–aside selenoamino isanzwe iboneka mu bimera no mu binyampeke by’ibiryo, aho selenium ihuzwa mu buryo bw’umwimerere. Ugereranyije na selenium idasanzwe (nka sodium selenite), L-selenomethionine itanga ibyiza bitatu by’ingenzi: uburozi buke, umwanda muke w’ibidukikije, no kuboneka cyane kw’ibinyabuzima. Kubera izi nyungu, amategeko ku isi yose yagiye agabanya buhoro buhoro amabwiriza ku ikoreshwa rya L-selenomethionine mu biryo, bituma iba amahitamo mashya yizewe mu mirire y’inyamaswa.

None se ni iki gituma L-selenomethionine igaragara? Ni akahe kamaro nyako ishobora kuzanira umusaruro w'amatungo? Reka'Reba neza.

1. Ni ikiL-Selenomethionine?

Niba utazi ibijyanye na biochimie, hano'Urugero rworoshye: Methionine ni aside amine y'ingenzi mu nyamaswa. L-selenomethionine ikorwa binyuze mu gusimbuza atome ya sulfur muri methionine na atome ya selenium. Uku gusimbuza bisa n'aho byoroshye kuyiha imiterere idasanzwe.

Muri kamere, selenium ibaho ahanini mu buryo bubiri–Inorganic na organic. Selenium isanzwe irimo sodium selenite na selenate, mu gihe selenium isanzwe yerekeza cyane cyane kuri aside selenoamino nka selenomethionine na selenocystine. L-selenomethionine ni yo shusho nyamukuru ya selenium iboneka mu musemburo wa selenium, ndetse ikaba n'isoko ryiganje rya selenium ikomoka ku bimera n'ibinyampeke.

L-selenomethionine ifite ubushobozi budasanzwe: ishobora kwinjiza mu buryo butaziguye inyamaswa igashyirwa muri poroteyine z’imitsi, umwijima, n’izindi ngingo, bigatuma umubiri uba ahantu habugenewe hashyirwa selenium. Ibinyuranye n’ibyo, ubundi bwoko bwa selenium (harimo selenium idakomoka ku binyabuzima n’izindi selenium zikomoka ku binyabuzima) amaherezo igabanuka ikaba hydrogen selenide, aho irenze iyo iva ikananirwa kubikwa. Ubushakashatsi bwagaragaje ko iyo inyama z’inkoko zihawe selenite ya sodium, igipimo cyo gusohora selenium kiba kiri hejuru inshuro eshatu ugereranyije n’iyo zihawe L-selenomethionine.–byemeza ko selenium idakora igoye kubika mu mubiri w'inyamaswa.

Ni ibi neza neza"kubika"imiterere ituma L-selenomethionine igaragara mu isoko ya selenium.

2. Ibyiza by'ingenzi byaL-Selenomethionine

2.1 Kuboneka cyane kw'ibinyabuzima

Muri rusange, abahanga mu bya siyansi bemeranya ko selenomethionine ifite ubushobozi bwo kuboneka mu bintu bya selenome. Inyamaswa zifata selenomethionine neza cyane kurusha selenometionine, bivuze ko selenometionine yongerwa mu biryo ikoreshwa neza kurusha gusohoka mu ifumbire.

2.2 Kongera ubudahangarwa bw'umubiri no kurwanya imihangayiko

Ubworozi bwa none butuma amatungo ahura n’ibintu bibangamira ibidukikije (urugero: ubushyuhe bwinshi, aho abantu baba, gutwara abantu). Mu gihe cy’imihangayiko, inyamaswa zikora ibintu byinshi byangiza uturemangingo tw’umubiri, bigatera kwangirika kw’uturemangingo no kwangirika kw’imikorere y’uturemangingo. L-selenomethionine ifite imbaraga zikomeye zo kurwanya utwo turemangingo, yongera imikorere ya enzymes z’ingenzi zo kurwanya utwo turemangingo nka glutathione peroxidase, ifasha inyamaswa gukuraho utwo turemangingo tw’umubiri no kongera ubudahangarwa bw’umubiri no kwihanganira imihangayiko.

2.3 Uruhare rw'Umutekano mu Buryo bwo hejuru

Ugereranyije na selenium idakomoka ku bimera, selenium y’umwimerere ntabwo ifite uburozi bwinshi kandi ntigira ingaruka ku bidukikije. Ishami rya EFSA FEEDAP ryanzuye ko L-selenomethionine ari nziza ku matungo yose mu gihe selenium yose mu biryo itarenze urugero rwemewe n’amategeko, kandi ko nta ngaruka ziyongera ku bidukikije itera.

3. Imikoreshereze n'ingaruka mu musaruro w'amatungo

3.1 Ubwiza bw'inkoko n'amagi yo gutera

L-selenomethioninebyakoreweho ubushakashatsi bwinshi mu nkoko zitera amagi. Ubushakashatsi bwerekana ko selenomethionine idatuma seleniyumu irushaho kwiyongera cyane mu magi ahubwo inatuma amagi aba meza kandi ikongera ubushobozi bwo kurwanya indwara ziterwa n’ingufu ndetse n’ubudahangarwa bw’inkoko zitera amagi. Iyo inkoko zororerwa mu magi zihawe L-selenomethionine, ubushobozi bwo kurwanya indwara ziterwa n’ingufu z’inkoko zibyara nabwo burarushaho kwiyongera.–bigaragaza ingaruka z'impinduka mu mibanire y'ababyeyi kuva ku mubyeyi kugeza ku mwana.

3.2 Ingurube

Mu ikorwa ry’ingurube, L-selenomethionine nayo ikora neza. Ubushakashatsi bwemeza ko selenomethionine yo mu mirire yongera ubushobozi bwo kurwanya antioxidant mu maraso no mu ngingo mu kurangiza ingurube kandi ikagabanya ibimenyetso by’ibyangiritse mu mubiri. Imikoreshereze yemewe ya L-selenomethionine yagutse ku bana b’ingurube bato n’inkoko zitera amagi, hamwe n’urugero rwatanzweho inama rwo kongeramo rutarenze 0.20 mg/kg (nk’ikintu cya selenium) mu biryo byuzuye ku bana b’ingurube bato.

3.3 Ubworozi bw'Amafi

Mu bworozi bw'amafi, L-selenomethionine nayo yageze ku ntambwe ikomeye. Ubushakashatsi bwerekana ko kongeramo 0.15 mg/kg ya selenomethionine mu kugaburira binoza imikorere y'amafi y'umuhondo mu gukura kwayo, bikongera ubushobozi bwo kurwanya indwara ziterwa n'imitsi. Mu 2025, mu Bushinwa,'Minisiteri y'Ubuhinzi n'Icyaro yongereye ikoreshwa rya L-selenomethionine mu mafi yo mu mazi meza, hamwe n'urugero rwatanzwe rw'inyongera rwa 0.4 mg/kg (hashingiwe ku bintu byumye bya 88%, nk'ikintu cy'ingenzi cya selenium) mu biryo byuzuye by'amafi yo mu mazi meza.

3.4 Inyama z'inka

Ku nyamaswa z’amatungo nka inka zitanga amata, selenium y’umwimerere yongera umusaruro, yongera ubudahangarwa bw’umubiri, yongera ubwiza bw’inyama, kandi yongera ubushobozi bwo kororoka. Itangazo ryo mu 2025 ryanemeye ikoreshwa rya L-selenomethionine mu nka zonsa, hamwe n’urugero rwatanzwe rw’inyongera rwa 0.3 mg/kg mu ngano yose ivanze.

4. Amategeko agenga imikorere ku isi"Amatara y'icyatsi kibisi"

Mu myaka ya vuba aha,L-selenomethionineyarushijeho kwemerwa ku mugaragaro ku isi yose.

Mu Bushinwa, Minisiteri y'Ubuhinzi n'Icyaro yongereye uburyo bwo gukoresha L-selenomethionine mu 2022 kugira ngo ishyiremo abana b'ingurube bato n'inkoko zitera amagi, aho ntarengwa ya selenium yose ingana na 0.50 mg/kg mu byo kurya byose. Mu 2025, uburyo bwo kongera gukoreshwa bwageze no ku mafi yo mu mazi meza n'inka zonsa. Izi politiki zoroshya uburyo bwo gukora ibiryo zituma abakora ibiryo byabo barushaho koroshya uburyo bwo kubitunganya.

Mu rwego mpuzamahanga, muri Gicurasi 2025, Ikigo gishinzwe kurwanya no gukumira ibiyobyabwenge cya Amerika (FDA) cyemeje zinc-L-selenomethionine nk'isoko y'intungamubiri ya seleniyumu mu biryo by'inkoko, guhera ku ya 19 Gicurasi 2025. Ikigo cy'Uburayi gishinzwe umutekano w'ibiribwa (EFSA) cyanasuzumye kenshi kandi cyemeza umutekano wa zinc-L-selenomethionine ku nyamaswa zose, abazirya, n'ibidukikije.

5. HitamoL-Selenomethioninekugira ngo habeho imirire myiza y'amatungo

Ukurikije amakuru ari hejuru, biragaragara impamvu L-selenomethionine irimo gukundwa n'inganda nyinshi zikora ibiryo by'amatungo–Bikemura ikibazo cy'ingenzi cy'isoko gakondo rya selenium: ikoreshwa rike no kutabasha kubikwa.

Kubera koL-selenomethionineishobora gushyirwa muri poroteyine z’inyamaswa, bigatuma umubiri uba ufite selenium ihagije, inyamaswa zigira selenium ihagije kugira ngo zikomeze gukora neza nubwo haba hari stress (urugero: kugabanya ibiryo mu gihe cy’ubushyuhe). Byongeye kandi, L-selenomethionine y’umwimerere, ifite aside amine imwe, itanga ubuzima bwiza kurusha ubwoko bw’ibikomoka ku bimera nk’umusemburo ukungahaye kuri selenium.

Sustar, ifite uburambe bw'imyaka irenga 35 mu mirire y'amatungo, yiyemeje gutanga ibintu by'ingenzi bifite ubuziranenge n'inyongeramusaruro ku batunganya ibiryo ku isi yose. Ibicuruzwa byacu bikubiyemo ibintu by'ingenzi bidafite ubuziranenge, ibintu by'ingenzi bidafite ubuziranenge, n'ibikomoka ku nyamaswa, hamwe n'amabuye y'agaciro ya peptide ntoya ari yo ayoboye uru ruganda. Dufite icyemezo cya ISO, GMP, na FAMI-QS kandi twashinze ubufatanye bw'igihe kirekire kandi buhamye n'ibigo bikomeye ku isi bitanga ibiryo nka Chia Tai Group, Cargill, DSM, ADM, Nutreco, na New Hope.

Mu rwego rwa selenium y'umwimerere, Sustar'Ibicuruzwa bya L-selenomethionine byubahiriza amabwiriza agenga ingano y'ibiryo. Abakora ibiryo by'amatungo n'abakiriya b'ubuhinzi barahawe ikaze kutwandikira kugira ngo tubashe kubaza ibibazo no kuganira ku bya tekiniki.

Iyi nkuru ishingiye ku bushakashatsi rusange n'amakuru y'inganda kugira ngo yigishwe kandi akoreshwe gusa. Nyamuneka kurikiza amabwiriza yo mu gace utuyemo n'amabwiriza ya tekiniki yo gukoresha ibicuruzwa.
