Posachedwapa, mutu wapoizoni wa aflatoxinKulima pa ma buns ophikidwa ndi nthunzi atasungidwa kwa masiku opitilira awiri kwadzetsa nkhawa kwa anthu ambiri. Kodi ndi kotetezeka kudya ma buns ophikidwa ndi nthunzi? Kodi ma buns ophikidwa ndi nthunzi ayenera kusungidwa bwanji mwasayansi? Ndipo tingapewe bwanji chiopsezo cha aflatoxin m'moyo watsiku ndi tsiku? Atolankhani apempha kutsimikiziridwa pankhaniyi.
"Ma buns ophikidwa ndi nthunzi yozizira sapanga aflatoxin pansi pa mikhalidwe yabwinobwino, chifukwa aflatoxin imapangidwa makamaka ndi nkhungu monga Aspergillus flavus m'malo otentha kwambiri komanso chinyezi chambiri. Malo ozizira (pafupifupi -18°C) salimbikitsa kukula kwa nkhungu," adatero Wu Jia, Wachiwiri kwa Mlembi Wamkulu wa Nutrition Literacy Branch ya Chinese Health Promotion and Education Association. Ngati ma buns ophikidwa ndi nthunzi adaipitsidwa kale ndi nkhungu asanaziziritsidwe, poizoni wa nkhungu sangachotsedwe ngakhale ataziziritsidwa. Chifukwa chake, ma buns ophikidwa ndi nthunzi yozizira omwe ndi atsopano komanso osapangidwa asanaziziritsidwe akhoza kudyedwa motsimikiza. Ngati ma buns ophikidwa ndi nthunzi ali ndi fungo losazolowereka, kusintha mtundu, kapena malo osazolowereka atasungunuka, ayenera kutayidwa kuti apewe kudyedwa.
Malinga ndi "Nutrition and Food Hygiene," aflatoxin ndi chinthu chomwe chimapangidwa ndi Aspergillus flavus ndi Aspergillus parasiticus, zomwe ndi bowa wamba m'tirigu ndi chakudya. Ku China, Aspergillus parasiticus ndi yosowa kwambiri. Kutentha kwa Aspergillus flavus kuti ikule ndikupanga aflatoxin ndi 12°C mpaka 42°C, ndipo kutentha kwabwino kwambiri kopangira aflatoxin ndi 25°C mpaka 33°C, ndipo kuchuluka kwa ntchito yamadzi ndi 0.93 mpaka 0.98.
Aflatoxin imapangidwa makamaka ndi nkhungu m'malo ofunda komanso achinyezi. Kutsatira njira zodzitetezera tsiku ndi tsiku kungachepetse chiopsezo chotenga aflatoxin ndikumwa. Akatswiri amalimbikitsa kusankha mitundu ndi ogulitsa odziwika bwino pogula chakudya kuti atsimikizire kuti chili chatsopano komanso chotetezeka. Posunga chakudya, muyenera kuyang'anitsitsa nthawi yosungira chakudya, ndipo chakudya chiyenera kusungidwa pamalo ouma, opumira bwino, komanso amdima kuti muchepetse mwayi woti nkhungu ikule. Ndikofunikira kwambiri kudziwa kuti kusunga chakudya mufiriji si njira yophweka, chifukwa chakudya chimakhala ndi nthawi yabwino yosungira. Pakukonza ndi kuphika chakudya, chakudya chiyenera kutsukidwa bwino, ndipo muyenera kuyang'anitsitsa njira zophikira.
Kuphatikiza apo, chifukwa cha kutentha kwabwino kwa aflatoxin, sichimawola mosavuta pophika ndi kutenthetsa mwachizolowezi. Chakudya chowuma chiyenera kupewedwa, ndipo ngakhale mbali yowumayo itachotsedwa, yotsalayo siyenera kudyedwa. Kuphatikiza apo, chidziwitso cha chitetezo cha chakudya chiyenera kukulitsidwa, ndipo ziwiya zakukhitchini monga zodulira ndi matabwa odulira ziyenera kutsukidwa mwachangu ndikusinthidwa nthawi zonse kuti zipewe kukula kwa nkhungu ndi mabakiteriya.
Ponena za kusungira kwasayansi kwa ma buns ophikidwa ndi nthunzi, Wu Jia adati kusungirako mufiriji ndiye njira yotetezeka komanso yabwino kwambiri yokoma. Komabe, ziyenera kudziwika kuti ma buns ophikidwa ndi nthunzi ayenera kutsekedwa m'matumba azakudya kapena pulasitiki kuti asakhudze mpweya, ateteze madzi kutuluka, komanso apewe kuipitsidwa ndi fungo loipa. Ma buns ophikidwa ndi nthunzi omwe sanadetsedwe ndi nkhungu akhoza kudyedwa mkati mwa miyezi isanu ndi umodzi ngati asungidwa mufiriji pansi pa -18°C. Mufiriji, amatha kusungidwa kwa tsiku limodzi kapena awiri komanso amafunika kutsekedwa kuti apewe chinyezi.
