I. Nhoroondo Yekushandisa
Calcium 2-hydroxy-4-(methylthio)butyrate (HMTBa-Ca) imhando yecalcium salt ye methionine hydroxy analogue (zita remakemikari: Calcium bis(2-hydroxy-4-(methylthio)butyrate)). Haipe zvakananga chimiro cheamino chine nitrogen asi inopa methionine carbon skeleton muchimiro chehydroxy analogue. Inoshandurwa mumuviri kuti igadzire L-methionine inoshanda mumuviri, iyo inobata mukugadzirwa kwemapuroteni uye maitiro akasiyana-siyana ekugadzirisa.
Methionine ndeimwe yemaamino acid anonyanya kuderedza kudya kwezvipfuyo nehuku, kunyanya inokonzerwa nekushaikwa kwekudya kwezviyo nesoya. Kuti igutse zvinodiwa nemhuka zve methionine, DL-methionine yagara ichiwedzerwa mukudya. Zvisinei, methionine hydroxy analogues uye calcium salts dzayo dziri kuwana mukurumbira zvishoma nezvishoma senzvimbo itsva dzemethionine. Kana ichienzaniswa neDL-methionine, HMTBa-Ca inopa kugadzikana kuri nani pakupisa uye kugadziriswa, zvichiita kuti ive nyore kuchengetedza zvinovaka muviri panguva yekudya kwezvipfuyo uye kugadzirwa kwekupisa kwakanyanya.
Boka reEuropean Food Safety Authority (EFSA) rakaita ongororo yakarongeka yekuchengetedzwa uye kushanda kweHMTBa nemunyu wayo wecalcium, richisimbisa kuchengetedzeka kwayo sechikafu chemhuka dzese. Haisiye zvasara munyama yemhuka kana zvigadzirwa uye haina njodzi huru dzezvakatipoteredza, ichipa rutsigiro rwemutemo rwekushandiswa kwayo mukudya kwemhuka.
II. Mhedzisiro Yekushandisa
Ongororo dzakawanda dzakaratidza kuti HMTBa-Ca, senzvimbo yemethionine, inogona kuvandudza kukura kwemhuka uye kushanda zvakanaka kwekudya kunovaka muviri. Munguruve, huku, uye mhuka dzemumvura, kuwedzerwa kweHMTBa-Ca kunogona kuwedzera avhareji yekuwedzera kwezuva nezuva, chiyero chekuchinja chikafu, uye kushandiswa kwenitrogen ukuwo kuchideredza kubviswa kwenitrogen. Izvi zvinobatsira zvikuru pakudya kusina mapuroteni akawanda kana amino acid yakagadzirwa nemazvo.
Muhuku, kuwedzerwa kweHMTBa-Ca hakungobatsiri chete kusimudzira kugadzirwa asi kunovandudzawo kugona kweantioxidant, kushanda kwemuviri kudzivirira zvirwere, uye hutano hwemudumbu. Muhuku dzinokandira mazai, kushandiswa kwayo kwakakodzera kunobatsira kuchengetedza kushanda kwemukaka uye kuvandudza kunaka kwemazai. Mumhuka dzemumvura, sezvo huwandu hwezvinhu zveprotein zvinobva mumiti huchiwedzera, kushomeka kwemethionine kunowedzera kuonekwa. Tsvagiridzo inoratidza kuti HMTBa-Ca inogona kushanda senzvimbo yekuwedzera inoshanda, ichivandudza kukura uye kuiswa kwemapuroteni mumuviri.
Senzira yekuvandudza methionine, HMTBa-Ca inogona kukurudzira kushandiswa kwemaamino acid akakosha uye kugadzirwa kwemapuroteni mumuviri uye kuvandudza kuumbwa kwemuviri nekudzora nzira dzemetabolism dzakabatana. Kunyangwe kushanda kwayo kwese kwese kuri kwakaderera pane kweDL-methionine, ichiri kuratidza kukosha kwakanyanya kwekudya mumhuka dzakasiyana. Mukushandiswa kwayo, huwandu hwakakodzera hwekuwedzera hunogona kugadzirwa zvine musoro uchishandisa zvinhu zvinoshandura.
III. Maitiro Ekuita
Maitiro ekushanda kweHMTBa-Ca anonyanya kukosha mubasa rayo semutangi wemethionine unobatanidzwa mukugadzirwa kwemukati memuviri. HMTBa-Ca inoshandurwa kuita L-methionine mudumbu kuburikidza nemaitiro e enzyme uye kugadzirwa kwe microbial. Zvadaro inobatawo mukugadzirwa kweprotein, kugadzirwa kwe one-carbon metabolism, uye kutonga kwe antioxidant systems (senge kugadzirwa kwe glutathione), ichiita basa rakakosha mukuchengetedza amino acid balance uye kuvandudza kushandiswa kwe nutrient.
Zvichienzaniswa neDL-methionine, nzira dzekunyudzwa uye kushandiswa kweHMTBa-Ca dzakasiyana zvishoma. Maumbirwo ayo ehydroxy analogue anopa mwero wekugadzikana kwakawedzerwa, kunyanya kuratidza humwe hunhu hwerumen bypass mumhuka dzinodya nyama, izvo zvinobatsira kuwedzera kuwanikwa kwemethionine muura hudiki.
IV. Mhando dzeMhuka Dzinonyanya Kunangwa
1. Nguruve (Nguruve Dzakarumurwa, Nguruve Dziri Kukura Nekupedzisa)
Mukudya kwenguruve, methionine ndeimwe yemaamino acid anodzivisa. Zvidzidzo zvakaratidza kuti kuwedzera HMTBa-Ca mukudya kune mapuroteni mashoma kana amino acid-balanced kunogona kuvandudza kushandiswa kwenitrogen zvinobudirira, kukurudzira kuiswa kweprotein, uye kuderedza kuburitswa kwenitrogen. Kana ichienzaniswa neDL-methionine yechinyakare, HMTBa-Ca inogona kusangana nezvinodiwa nemethionine uku ichivandudza kushanda kweamino acid. Yakakodzera zvakanyanya pakudzora kudya panguva yekuremurwa uye munguruve dzine nyama isina mafuta akawanda.
2. Huku (Huku dzemabhuru, Huku dzinoyamwisa, Vanoberekesa)
Mukudya kwehuku, HMTBa-Ca inoshandiswa zvakanyanya kutsiva kana kutsiva DL-methionine zvishoma. Tsvagiridzo inoratidza kuti kuwedzerwa kwayo kunogona kuvandudza avhareji yehuwandu hwezuva nezuva hwekudya uye huwandu hwekudya kwehuku uye kunokanganisa kugona kweantioxidant, immune parameters, uye hutano hwemudumbu. Muhuku dzinoisa mazai, kuwedzerwa kwakakodzera kweHMTBa-Ca kunobatsira kuchengetedza kushanda kwekuisa mazai, kuvandudza kunaka kwemazai, uye kutora chikamu mukudzora metabolism yeprotein nesulfur amino acid, iyo inonyanya kukosha kune dzinoisa mazai akawanda.
3. Mhuka dzemumvura (Hove, shiri dzerudzi rweCrustacean)
Muchikafu chemumvura, nekuda kwekuwedzera kwehuwandu hwezvinhu zveprotein zvinobva mumiti, kushomeka kwemethionine kwave kuchiwedzera. Ongororo dzakawanda dzinoratidza kuti HMTBa-Ca inogona kushanda senzvimbo inoshanda yemethionine mukudya kwehove (semuenzaniso, hove dzegungwa, hove dzemugungwa), zvichivandudza zvakanyanya kukura kwayo, kushandiswa kwechikafu, uye kuiswa kwemapuroteni mumuviri. Kugadzikana kwayo uye kuchinjika kwayo munzvimbo dzemumvura kunoita kuti ikwanise kushandiswa zvakanaka mukudya kwemumvura kwakagadzirwa.
4. Mhuka dzinodya nyama (Mombe dzemukaka, Mombe dzemombe, Makwai)
Kusiyana nezvisiri zvemhuka dzinodya nyama, methionine mukudya kwemhuka dzinodya nyama inowanzo deredzwa nekuora kwemasero emuviri, zvichiita kuti mafomu ekuwedzera emethionine ashande zvakanaka ave akakosha. Tsvagiridzo inoratidza kuti methionine hydroxy analogues (kusanganisira calcium salt yavo) ine simba rekudzivirira kuora kwemasero mudumbu, zvichiita kuti pave nekubuda zvishoma kubva mukuviriswa kwemasero emuviri uye kushandurwa kuita methionine inoshandiswa muura hudiki, nokudaro zvichiwedzera kuwanikwa kwemapuroteni anogona kushandiswa.
V. Mhedziso neMaonero
Mukupfupisa, HMTBa-Ca, senzvimbo itsva yekuwedzera methionine, inoratidza kugona kwayo kushandiswa mukudya kwemhuka. Ongororo yeramangwana inofanira kutarisa nzira dzekuvandudza kushanda kwayo kwehupenyu, kuona huwandu hwayo hwekuwedzera kune mhando dzakasiyana dzemhuka uye matanho ekukura, uye kuongorora mhedzisiro yayo pamwe chete nezvimwe zvinowedzera zvekudya. Izvi zvichasimudzira kushandiswa kwayo kwakanaka uye kunobudirira muzvirongwa zvemazuva ano zvekudya.
