Txog

Cov khoom siv no tuaj yeem siv rau hauv kev txheeb xyuas qhov ntau thiab zoo ntawm AOZ residue hauv cov ntaub so ntswg tsiaj (nqaij qaib, nyuj, npua, thiab lwm yam), mis nyuj, zib ntab thiab qe.

Kev soj ntsuam ntawm cov tshuaj nitrofuran residue yuav tsum tau ua raws li kev tshawb nrhiav cov ntaub so ntswg khi metabolites ntawm cov tshuaj nitrofuran niam txiv, uas suav nrog Furazolidone metabolite (AOZ), Furaltadone metabolite (AMOZ), Nitrofurantoin metabolite (AHD) thiab Nitrofurazone metabolite (SEM).

Piv nrog rau cov txheej txheem chromatographic, peb cov khoom siv qhia tau hais tias muaj txiaj ntsig zoo txog kev rhiab heev, kev txwv tsis pub, cov cuab yeej siv thiab lub sijhawm xav tau.
