Kugwa ndi nyengo yokolola chimanga, nthawi zambiri, mzere wa mkaka wa chimanga ukasowa, tsinde pamakhala nsanjika wakuda, ndipo chinyezi cha chimanga chimatsika kufika pamlingo wakutiwakuti, chimangacho chimatha kuwonedwa kuti chakucha komanso chokonzeka. za kukolola. Chimanga kukolola pa nthawi ino si mkulu zokolola ndi zabwino, komanso abwino wotsatira kusungidwa ndi processing.
Chimanga chimadziwika kuti ndi imodzi mwa mbewu zotchuka kwambiri. Komabe, panthawi imodzimodziyo, chimanga chingakhalenso ndi ma mycotoxins, kuphatikizapo aflatoxin B1, vomitoxin ndi zearalenone, omwe angakhale owopsa kwa thanzi la anthu ndi nyama, motero amafunikira njira zoyezera ndi kuwongolera kuti atsimikizire chitetezo ndi khalidwe la chimanga ndi thanzi. mankhwala ake.
1. Aflatoxin B1 (AFB1)
Zomwe zili zofunika kwambiri: Aflatoxin ndi mycotoxin yodziwika bwino, yomwe aflatoxin B1 ndi imodzi mwa ma mycotoxin ofala kwambiri, owopsa komanso owopsa. Ndi physicochemical yokhazikika ndipo imayenera kufika kutentha kwa 269 ℃ kuti iwonongeke.
Zowopsa: Poizoni pachimake angasonyeze monga malungo, kusanza, kusowa chilakolako cha kudya, jaundice, etc. Mu milandu kwambiri, ascites, kutupa m`munsi miyendo, hepatomegaly, splenomegaly, kapena imfa mwadzidzidzi akhoza kuchitika. Kudya kwanthawi yayitali kwa aflatoxin B1 kumalumikizidwa ndi kuchuluka kwa khansa ya chiwindi, makamaka omwe ali ndi matenda a chiwindi omwe amatha kudwala kwambiri komanso kuyambitsa khansa ya chiwindi.
2. Vomitoxin (Deoxynivalenol, DON)
Zinthu zazikuluzikulu: Vomitoxin ndi mycotoxin ina yodziwika bwino, mawonekedwe ake a physicochemical amakhala okhazikika, ngakhale kutentha kwambiri kwa 120 ℃, ndipo sikophweka kuwonongedwa pansi pa acidic.
Zowopsa: Poizoni amawonekera makamaka m'matumbo am'mimba ndi zizindikiro zamanjenje, monga nseru, kusanza, kupweteka mutu, chizungulire, kupweteka m'mimba, kutsekula m'mimba, etc. kuledzera.
3. Zearalenone (ZEN)
Zinthu zazikuluzikulu: Zearalenone ndi mtundu wa non-steroidal, mycotoxin ndi katundu wa estrogenic, katundu wake wa physicochemical ndi wokhazikika, ndipo kuipitsidwa kwake mu chimanga kumakhala kofala.
Zoopsa: Zimakhudza kwambiri zoberekera, ndipo zimakhudzidwa kwambiri ndi nyama monga nkhumba, ndipo zimatha kubereka ndi kuchotsa mimba. Ngakhale kuti palibe malipoti okhudza poizoni wa anthu, akuganiza kuti matenda a anthu okhudzana ndi estrogen angakhale okhudzana ndi poizoni.
