Elisa Ikhithi yoVavanyo ye-Aflatoxin B1
Iidosi ezinkulu ze-aflatoxins zikhokelela kwityhefu ebukhali (i-aflatoxicosis) enokubeka ubomi esichengeni, ngokwesiqhelo ngomonakalo esibindini.
I-Aflatoxin B1 yi-aflatoxin eveliswa yi-Aspergillus flavus kunye ne-A. parasiticus.Yi-carcinogen enamandla kakhulu.La mandla e-carcinogenic ayohluka kwiintlobo ngeentlobo nezinye, ezinje ngeempuku kunye neenkawu, zibonakala zichaphazeleka ngakumbi kunezinye.I-Aflatoxin B1 yingcoliseko eqhelekileyo kwiindidi zokutya okuquka amandongomane, i-cottonseed meal, umbona, kunye nezinye iinkozo;ngokunjalo nokutya kwezilwanyana.I-Aflatoxin B1 ithathwa njengeyona ityhefu ye-aflatoxin kwaye ibandakanyeka kakhulu kwi-hepatocellular carcinoma (HCC) ebantwini.[cating] Kwizilwanyana, i-aflatoxin B1 ikwabonakaliswe njenge-mutagenic, i-teratogenic, kwaye ibangela ukugonywa komzimba.Iisampulu ezininzi kunye neendlela zohlalutyo ezibandakanya i-chromatography (TLC), i-high-performance liquid chromatography (HPLC), i-mass spectrometry, kunye ne-enzyme-linked immunosorbent assay (ELISA), phakathi kwezinye, zisetyenziselwe ukuvavanya ukungcoliseka kwe-aflatoxin B1 ekutyeni. .Ngokutsho kwe-Food and Agriculture Organisation (FAO), amanqanaba aphezulu anyanyezelwayo e-aflatoxin B1 emhlabeni wonke axelwe ukuba akuluhlu lwe-1-20 μg/kg ekutyeni, kunye ne-5-50 μg/kg kwisondlo senkomo esityayo ngo-2003.
