Elisa Test Kit yeAflatoxin B1

Tsanangudzo Pfupi:

Mahombe madosi eaflatoxins anotungamira kune acute chepfu (aflatoxicosis) inogona kutyisidzira hupenyu, kazhinji kuburikidza nekukuvadza kuchiropa.

Aflatoxin B1 iaflatoxin inogadzirwa neAspergillus flavus uye A. parasiticus.Iyo ine simba zvikuru carcinogen.Iyi carcinogenic potency inosiyana pakati pezvipenyu nedzimwe, senge makonzo netsoko, zvinoita kunge zviri nyore kupfuura dzimwe.Aflatoxin B1 inowanzosvibiswa mune zvakasiyana-siyana zvekudya zvinosanganisira nzungu, cottonseed meal, chibage, nezvimwe zviyo;pamwe chete nezvokudya zvezvipfuwo.Aflatoxin B1 inoonekwa seaflatoxin ine muchetura uye inonyanya kukonzeresa muhepatocellular carcinoma (HCC) muvanhu.Nzira dzinoverengeka dzesampling uye dzekuongorora dzinosanganisira dzakatetepa-layer chromatography (TLC), yakakwira-performance liquid chromatography (HPLC), mass spectrometry, uye enzyme-yakabatana immunosorbent assay (ELISA), pakati pevamwe, yakashandiswa kuyedza kusvibiswa kweaflatoxin B1 muchikafu. .Sekureva kweFood and Agriculture Organisation (FAO), huwandu hwepasi rose hunoshivirira huwandu hweaflatoxin B1 hwakanzi hwaive pakati pe1-20 μg/kg muchikafu, uye 5–50 μg/kg mukudya kwemombe muna 2003.
