Siyajabula ukumemezela ukuthi ezintathu zazoImikhiqizo yokulinganisa i-toxin fluorescence ye-KwinbonKuhlolwe yiNational Feed Quality Inspection and Testing Centre (Beijing).

Ukuze kuqondwe njalo ikhwalithi yamanje kanye nokusebenza kwemikhiqizo ye-mycotoxin immunoassay (amakhithi, amakhadi okuhlola/imichilo kanye nemikhiqizo ehlobene nayo) emakethe yasekhaya, i-National Center for Feed Quality Inspection and Testing (Beijing) yenze ukuhlolwa kwemikhiqizo ye-mycotoxin immunoassay ngoJulayi 2024.

Ama-Mycotoxin ayizinto ezikhiqizwa yi-fungi ethile (isib. i-Aspergillus, i-Penicillium kanye ne-Fusarium) ngesikhathi sokukhula kwawo ezivame ukubangela izinguquko ze-pathological kanye nokuguqulwa kwesimo somzimba kubantu, futhi zinobuthi obukhulu. Njengamanje, kunezinhlobo ezingaphezu kuka-400 zama-mycotoxins ezaziwayo, ezivamile yi-aflatoxin, i-ochratoxin, i-ergot alkaloids, i-deoxynivalenol njalo njalo.

Ama-mycotoxin angase angajwayelekile emphakathini, kodwa empeleni, le metabolite yesikhunta enobuthi kakhulu futhi ebangela umdlavuza isingene cishe kuzo zonke izinhlobo zemikhiqizo yezolimo edliwayo neyokudla. Kusukela kummbila, ukolweni, ibhali namakinati kuya ezithelweni ezomisiwe, izithelo, izinongo, amakhambi nobisi, ama-mycotoxin atholakala yonke indawo futhi athinta ngisho nokuphepha kwemvelo njengoba uchungechunge lwezimboni zabantu nezilwane luthuthuka.

Ama-mycotoxins amelana nokugqwala kanye nokushisa okuphezulu, futhi angangcolisa ukudla futhi kunzima ukuwasusa kuzo zonke izigaba zokukhiqizwa kokudla, okuhlanganisa ukutshala, ukutshala, ukucubungula, ukuthuthwa kanye nokupheka. Ngakho-ke, izindlela zokuhlola zobungcweti, njenge-chromatography, i-immunoassay kanye ne-real-time fluorescence quantitative PCR, ziyadingeka ukuze kutholakale ngokunembile ama-mycotoxins ekudleni.

Imikhiqizo emithathu ye-Kwinbon - Aflatoxin B1 Residue Fluorescence Quantitative Test Strips, i-Vomitoxin Residue Fluorescence Quantitative Test Strips kanye ne-Zearalenone Residue Fluorescence Quantitative Test Strips iphumelele ukuhlolwa, kanti izinkomba zokuhlola eziyinhloko zifaka: ukusebenza, ukunemba kanye nekhono lokuthola amasampula angempela kanye nezinye izici ezintathu.
