Cov txheej txheem nquag siv rau
tshawb nrhiav mycotoxin Yog raws li nram no:
I. TLC:
Txoj kev TLC yog tsom rau cov qauv sib txawv. Cov mycotoxin tau muab rho tawm los ntawm cov qauv nrog cov kuab tshuaj tsim nyog tsim nyog, ua kom huv los ntawm kem chromatography, thiab tom qab ntawd nthuav dav thiab sib cais ntawm txheej txheej nyias nyias chromatography. Cov fluorescence ntawm mycotoxins tau siv los txiav txim siab cov ntsiab lus yam tsawg kawg los ntawm kev sib piv nws lub zog nrog tus qauv. TLC cov qauv kev npaj yog qhov nyuaj, thiab kev rho tawm thiab kev ua kom huv tsis zoo. Muaj ntau yam tsis huv nyob rau hauv cov tshuaj rho tawm, uas cuam tshuam rau kev siv lub teeb ci ntawm qhov chaw thaum nthuav dav.
2. Chromatography:
Chromatography, suav nrog cov txheej txheej chromatography, cov pa roj chromatography, thiab cov kua chromatography, ib txwm yog qhov tseem ceeb tshaj plaws tshuaj tshuaj rau mycotoxins. Txoj hauv kev ntau dua los txheeb xyuas mycotoxins tseem yog cov kua chromatography, suav nrog kua chromatography-mass spectrometry. Txoj kev no yog nrawm thiab raug, tab sis xav tau cov cuab yeej thiab khoom siv kim. Nws tsuas yog txwv rau cov koom haum kev xeem nkag mus rau kev tshawb fawb tshawb fawb, tshawb nrhiav, tshuaj xyuas, thiab tshuaj xyuas. Nws tsis tau siv dav hauv kev lag luam thiab hauv paus. Ntxiv mus, cov txiaj ntsig lag luam ntawm nws cov txiaj ntsig tau txo qis qhov tsim tawm Cov Lus Qhia Zoo.
3. Txoj hauv kev kuaj tshuaj tiv thaiv kab mob: (colloidal kub immunochromatography, enzyme-txuas immunosorbent kuaj):
Kev tshawb nrhiav kab mob tiv thaiv kab mob yog ib qho kev tshuaj ntsuam biochemical raws li kev xaiv cov tshuaj tiv thaiv ntawm cov tshuaj tiv thaiv kab mob thiab antigens lossis haptens. Feem ntau muaj kev xaiv siab thiab qis qis nrhiav kom tau. Nws tau siv dav rau kev txiav txim siab ntawm ntau yam antigens, ib nrab tshuaj tiv thaiv kab mob lossis tshuaj tiv thaiv kab mob. Feem ntau, nws tuaj yeem faib ua fluorescent immunoassay.
Qhov ntsuas zoo tshaj plaws mycotoxin yog tso zis, vim tias mycotoxins sib sau hauv lub siab thiab ob lub raum. Yog li kev kuaj cov zis kuj yooj yim dua thiab tsis kis tau.
