BALLYA Ochratoxin Kev xeem yog qhov ntsuas nrawm ib qib uas tuaj yeem tsim nyog (lossis muaj nuj nqis) txheeb xyuas ochratoxin A hauv
nplej thiab cov roj noj tau hauv yim feeb xwb.
Ochratoxin A. (OTA) yog cov tshuaj metabolite thib ob uas tsim los ntawm ntau yam Aspergillus thiab Penicillium fungi. Nws feem ntau ua paug cov qoob loo thiab cov qoob loo. OTA tau kuaj pom ntau yam nplej thiab khoom.
Ochratoxin A tau txiav txim siab los ntawm lub koom haum thoob ntiaj teb rau kev tshawb fawb txog mob qog noj ntshav (iarc) rau Ⅱ chav kawm B carcinogen hauv cov co toxins. Nws tuaj yeem ua rau mob qog noj ntshav, yug menyuam tsis zoo, ua rau lub cev tsis muaj zog, ua rau lub siab, lub raum puas tsuaj, thiab tseem tuaj yeem ua rau lub paj hlwb puas.
OTA tsis zoo hauv dej-soluble, soluble hauv sodium bicarbonate tov, thiab yooj yim soluble hauv cov kuab tshuaj xws li cawv, ketone thiab chloroform. OTA tau pom thawj zaug hauv Balkans. Balkan tus kab mob nephropathy thiab nws cov qog nqaij hlav hauv lub cev muaj feem cuam tshuam nrog kev ua qias tuaj ntawm OTA. Balkan phaum mob nephropathy yog mob hnyav thiab mob hnyav, thiab cov neeg mob mus sij hawm ntev (6-10 xyoo) tej zaum yuav hloov pauv tsis tau lub raum. Ib qho ntxiv, OTA kuj tseem suav tias yog lub hauv paus tseem ceeb ntawm kev mob raum hauv Tunisia.
Cov tshuaj lom no ruaj khov heev. Nws tsis tuaj yeem ua kom puas txawm tias ntawm 250 ° C. Fermentation tuaj yeem txo qis txog 70% ntawm cov co toxins. 98% ntawm
ochratoxin tuaj yeem degraded los ntawm cov kab mob rumen. Kev ruaj khov ntawm ochratoxin hauv nqaij npuas, lub raum npua thiab lub siab npua yog siab heev, thiab poob cov tshuaj lom los ntawm kev ua noj yog me me heev.
Nws inhibits phenylalanine-tRNA synthetase kev ua, yog li inhibiting protein synthesis; ua rau muaj kev ua haujlwm tsis txaus ntawm mitochondrial, yog li inhibiting cell metabolism hauv zog. OTA ua rau muaj kev nyuab siab oxidative ua rau nws ua rau mob qog noj ntshav, ua rau lub cev muaj tshuaj lom thiab cytotoxic.
OTA yog hom mycotoxin tsim los ntawm Aspergillus ochracea thiab Penicillium ntsuab ntsuab. Nws yog dav nyob hauv
pub. Npua yog rhiab rau nws thiab muaj cov txiaj ntsig sib xyaw nrog aflatoxin. OTA muaj cov nyhuv diuretic muaj zog thiab feem ntau ua rau lub raum ntawm npua. Cov tshuaj lom ntau tuaj yeem ua rau lub siab puas rau hauv npua, ua rau mob o lossis mob necrosis ntawm cov hnyuv mucosa, ua rau lub cev puas tsuaj thiab lwm yam tsos mob.
Cov pa phem ntawm OTA hauv kev pub tsiaj yog qhov hnyav. OTA sib sau ua ke hauv lub cev tom qab tus tsiaj noj cov khoom noj uas kis los ntawm OTA, thiab tsis yooj yim los ntawm cov metabolism. Yog li ntawd, hauv tsiaj zaub mov, tshwj xeeb yog lub raum npua, daim siab, leeg nqaij, ntshav, thiab mis thiab khoom siv mis, Ochratoxin A feem ntau tau kuaj pom. Hauv tsev neeg ntawm
mycotoxins uas tau tshawb pom, raws li lawv qhov tseem ceeb thiab qeb phom sij, OTA suav tias yog thib ob rau aflatoxin. Txog tam sim no, cov tebchaws xws li Brazil, Lub Tebchaws Yelemees, Romania, Hungary, thiab Czechoslovakia tau tsim cov qauv txwv rau OTA hauv zaub mov, pub mis thiab lub raum npua.
Vim tias cov ntsiab lus ntawm ochratoxin A hauv cov qoob loo qis heev, txoj hauv kev sim yuav tsum muaj txiaj ntsig. Cov kws tshawb fawb ntsig txog thoob ntiaj teb tau ua ntau txoj kev tshawb fawb ntawm ochratoxin A, thiab txoj hauv kev tshawb pom tam sim no tau muab faib ua ob pawg: cov txheej txheem lees paub thiab cov txheej txheem nrawm.
Kev lees paub txoj hauv kev feem ntau yog ua los ntawm cov cuab yeej siv lub cev thiab tshuaj lom neeg, xws li txheej txheej chromatography (TLC), roj chromatography (GC), cov kua siab ua kua chromatography (HPLC), thiab ntau yam sib xyaw thev naus laus zis xws li roj-huab hwm coj spectrometry (GC-MS) , kua ua kua spectrometry ua ke (HPLC-MS), thiab lwm yam; Cov txheej txheem nrawm feem ntau yog ua raws cov txheej txheem tshuaj tiv thaiv kab mob tiv thaiv kab mob xws li tiv thaiv kab mob tiv thaiv kab mob fluorescence (IAC-FLD), enzyme-txuas immunosorbent assay (ELlSA) thiab
colloidal kub immunochromatography thiab lwm yam
TLC yog txoj hauv kev nrhiav pom feem ntau hauv kev tshawb fawb thaum ntxov ntawm ochratoxin A. Nws tau siv dav vim tias nws yooj yim ua haujlwm. Txawm li cas los xij, txoj hauv kev no siv sijhawm ntev (li 48 teev), thiab qhov ua tau zoo thiab qhov tshwj xeeb tsis zoo. Cov kuab tshuaj organic xav tau hauv tus txheej txheem sib txawv thiab muaj ntau.
HPLC txoj hauv kev muaj qhov nkag siab zoo thiab tuaj yeem txheeb xyuas qhov muaj txiaj ntsig zoo thiab muaj nuj nqis los tshuaj xyuas cov tshuaj ochratoxin A hauv cov qauv, tab sis txoj hauv kev no tsis haum rau kev kuaj pom ntawm cov qauv.
Kev tshuaj tiv thaiv kab mob tiv thaiv kab mob enzyme ELISA txoj kev yog siv ntau txoj hauv kev kuaj pom sai hauv cov tuam txhab, tab sis nws kuj muaj qhov zoo thiab qhov tsis zoo: ELISA txoj hauv kev tuaj yeem ua rau nkag siab thiab ntsuas tau ntau, tab sis txheej txheem kev ua haujlwm yog nyuab nyuab, xav tau ib puag ncig thiab cov neeg ua haujlwm siab, thiab ib puag ncig cuam tshuam cuam tshuam yog qhov nyuaj.
Ochratoxin Cov Khoom Siv Ceev Ceev yog colloidal kub immunochromatography kuaj pom tias Ochratoxin Ib qho seem hauv cov nplej, pub thiab ua tau raws li EU MRL. BALLYA daim npav nrhiav xim kub tuaj yeem ua tau raws qhov xav tau sai ntawm daim teb, thiab ua tiav tsis pub dhau 5-10 feeb, thiab tuaj yeem ua tau zoo lossis muaj txiaj ntsig nrog kev nkag siab siab.
Cov khoom no siv cov txheej txheem sib tw kub sib xyaw kom paub sai sai ntawm cov tshuaj ochratoxin A hauv cov nplej thiab txau los ntawm cov tshuaj tiv thaiv kab mob tshwj xeeb antigen-antibody. Nws yog qhov tsim nyog rau ntawm qhov chaw tshawb xyuas sai ntawm ntau lub tuam txhab, kuaj cov tsev haujlwm thiab saib xyuas haujlwm.
Cov qauv ntsuas suav nrog: cov nplej, khoom noj, thiab cov khoom lag luam xws li npias thiab
siv roj.
LOD tej zaum yuav hloov pauv raws li qhov xav tau lossis cov qauv sib txawv, xa mus rau cov khoom qhia
Kev tshuaj Ochratoxin tuaj yeem pab cov tuam txhab tsim khoom, cov koom haum tswj hwm, thiab cov pej xeem saib xyuas cov khoom lag luam zoo thiab pab tib neeg tiv thaiv lawv txoj kev noj qab haus huv.
