Posachedwapa, mutu waaflatoxinKulima pa ma buns owuma atasungidwa kwa masiku opitilira awiri kwadzetsa nkhawa anthu. Kodi ndi bwino kudya mabazi owuzidwa ndi nthunzi? Kodi mabazi otenthedwa ayenera kusungidwa bwanji mwasayansi? Ndipo tingapewe bwanji chiopsezo chokhala ndi aflatoxin m'moyo watsiku ndi tsiku? Atolankhani akufuna kutsimikizira pankhaniyi.
"Mabangi oundana oundana satulutsa aflatoxin m'mikhalidwe yabwinobwino, chifukwa aflatoxin imapangidwa makamaka ndi nkhungu monga Aspergillus flavus m'malo otentha kwambiri, okhala ndi chinyezi chambiri. "Anatero Wu Jia, Wachiwiri kwa Mlembi Wamkulu wa Nutrition Literacy Nthambi ya Chinese Health Promotion and Education Association. Ngati ma buns otenthedwa atayipitsidwa kale ndi nkhungu asanauzidwe, poizoni wa nkhungu sangachotsedwe ngakhale ataundana. Chifukwa chake, mabatani owuma owuma omwe amakhala atsopano komanso osawumbidwa asanauzidwe amatha kudyedwa molimba mtima. Ngati mabatani otenthedwa ali ndi fungo losazolowereka, kusintha kwa mtundu, kapena malo osawoneka bwino atatha kusungunuka, ayenera kutayidwa kuti asamwe.
Malinga ndi "Nutrition and Food Hygiene," aflatoxin ndi metabolite yopangidwa ndi Aspergillus flavus ndi Aspergillus parasiticus, omwe ndi mafangasi omwe amapezeka mumbewu ndi chakudya. Ku China, Aspergillus parasiticus ndi osowa. Kutentha kosiyanasiyana kwa Aspergillus flavus kuti ikule ndi kupanga aflatoxin ndi 12°C mpaka 42°C, ndi kutentha kwabwino kwambiri kwa kupanga aflatoxin kukhala 25°C mpaka 33°C, ndipo ntchito yabwino ya madzi ndi 0.93 mpaka 0.98.
Aflatoxin imapangidwa makamaka ndi nkhungu m'malo otentha komanso a chinyezi. Kusamala m'moyo watsiku ndi tsiku kungathe kuchepetsa chiopsezo chodziwika ndi kuyamwa kwa aflatoxin. Akatswiri amalangiza kusankha mitundu yodziwika bwino komanso ogulitsa pogula chakudya kuti zitsimikizire kuti ndizatsopano komanso zotetezeka. Posunga chakudya, chisamaliro chiyenera kuperekedwa ku nthawi ya alumali, ndipo chakudya chiyenera kusungidwa pamalo owuma, mpweya wabwino, ndi wamdima kuti achepetse mwayi wa nkhungu. Ndikofunika kwambiri kuzindikira kuti kusunga chakudya mufiriji si njira yopanda nzeru, chifukwa zakudya zimakhala ndi nthawi yabwino yosungira. Panthawi yokonza ndi kuphika, zakudya ziyenera kutsukidwa bwino, ndipo chisamaliro chiyenera kuperekedwa ku njira zophikira.
Komanso, chifukwa cha kukhazikika kwa kutentha kwa aflatoxin, sikuwonongeka mosavuta ndi kuphika ndi kutenthedwa wamba. Zakudya za nkhungu ziyenera kupewedwa, ndipo ngakhale mbali ya nkhungu itachotsedwa, yotsalayo sayenera kudyedwa. Kuwonjezera pamenepo, anthu azidziwa bwino za chitetezo cha chakudya, ndipo ziwiya zakukhitchini monga zomangira ndi matabwa ziyenera kutsukidwa mwamsanga ndi kusinthidwa pafupipafupi kuti nkhungu ndi mabakiteriya asakule.
Ponena za kusungirako kwasayansi kwa ma buns otenthedwa, Wu Jia adati kusungirako mazira ndi njira yotetezeka komanso yokoma kwambiri. Komabe, ziyenera kudziwidwa kuti ma buns otenthedwa ayenera kutsekedwa m'matumba a chakudya kapena pulasitiki kuti asakhudzidwe ndi mpweya, kupewa kutuluka kwa madzi, komanso kupewa kuipitsidwa ndi fungo. Mabande otenthedwa omwe sanaipitsidwe ndi nkhungu amatha kudyedwa mkati mwa miyezi isanu ndi umodzi ngati atasungidwa m'malo oundana osakwana -18°C. M'malo afiriji, amatha kusungidwa kwa tsiku limodzi kapena awiri koma amafunikanso kusindikizidwa kuti asanyowe.
