Kwinbon Mycotoxin Testing Program in Corn

Ikwindla inkathi yokuvunwa kommbila, uma sikhuluma ngokujwayelekile, lapho uhlamvu lobisi lwembewu yommbila lunyamalala, kuvele ungqimba olumnyama phansi, futhi umswakama wohlamvu wehla ufike ezingeni elithile, ummbila ungabhekwa njengovuthiwe futhi usulungile. okokuvuna. Ummbila ovunwa ngalesi sikhathi awukona nje kuphela ukukhiqiza okuphezulu kanye nekhwalithi enhle, kodwa futhi uvumela ukugcinwa nokucubungula okulandelayo.

Ummbila udumile njengomunye wezinhlamvu eziyisisekelo. Kodwa-ke, ngesikhathi esifanayo, ummbila ungase futhi ube nama-mycotoxins athile, okuhlanganisa i-aflatoxin B1, vomitoxin ne-zearalenone, okungenzeka abe yingozi empilweni yomuntu neyezilwane, futhi ngenxa yalokho adinga izindlela zokuhlola ezisebenzayo nezindlela zokulawula ukuze kuqinisekiswe ukuphepha kanye nekhwalithi yommbila kanye nemvelo. imikhiqizo yayo.

1. I-Aflatoxin B1 (AFB1)

Izici eziyinhloko: I-Aflatoxin iyi-mycotoxin evamile, lapho i-aflatoxin B1 ingenye yama-mycotoxins asabalele kakhulu, anobuthi kanye ne-carcinogenic. Iqinile ngokwe-physicochemical futhi idinga ukufinyelela izinga lokushisa eliphakeme lama-269 ℃ ukuze ichithwe.

Izingozi: Ubuthi obunamandla bungase bubonakale njengomkhuhlane, ukuhlanza, ukuphelelwa ukudla, i-jaundice, njll. Ezimweni ezimbi kakhulu, i-ascites, ukuvuvukala kwezitho ezingezansi, i-hepatomegaly, splenomegaly, noma ngisho nokufa kungazelelwe. Ukudla isikhathi eside kwe-aflatoxin B1 kuhlotshaniswa nokwanda kwezigameko zomdlavuza wesibindi, ikakhulukazi labo abanesifo sokusha kwesibindi esisengozini yokuhlaselwa futhi babangele umdlavuza wesibindi.

2. I-Vomitoxin (Deoxynivalenol, DON)

Izici eziyinhloko: I-Vomitoxin ingenye i-mycotoxin evamile, izici zayo ze-physicochemical zizinzile, ngisho namazinga okushisa aphezulu angu-120 ℃, futhi akulula ukubhujiswa ngaphansi kwezimo ezine-asidi.

Izingozi: Ubuthi bubonakala kakhulu ohlelweni lokugaya ukudla kanye nezimpawu zesistimu yezinzwa, njengokucanuzela kwenhliziyo, ukuhlanza, ikhanda elibuhlungu, isiyezi, ubuhlungu besisu, isifo sohudo, njll. ukudakwa.

3. I-Zearalenone (ZEN)

Izici eziyinhloko: I-Zearalenone iwuhlobo lwe-non-steroidal, i-mycotoxin enezici ze-estrogenic, izici zayo ze-physicochemical zizinzile, futhi ukungcoliswa kwayo emmbila kuvame kakhulu.

Izingozi: Isebenza kakhulu ohlelweni lokuzala, futhi izwela kakhulu ezilwaneni ezinjengezinsikazi, futhi ingabangela inzalo kanye nokukhipha isisu. Nakuba ingekho imibiko yobuthi babantu, kucatshangwa ukuthi izifo zabantu ezihlobene ne-estrogen zingase zihlobane nalobu buthi.
