Muva nje, isihloko se-i-aflatoxinUkukhula kuma-buns aqandisiwe aphekiwe ngemva kokugcinwa izinsuku ezingaphezu kwezimbili kubangele ukukhathazeka emphakathini. Ingabe kuphephile ukudla ama-buns aqandisiwe aphekiwe? Ama-buns aphekiwe kufanele agcinwe kanjani ngokwesayensi? Futhi singayivimbela kanjani ingozi yokuchayeka ku-aflatoxin empilweni yansuku zonke? Izintatheli zifune ukuqinisekiswa ngalezi zindaba.
"Ama-buns aqandisiwe aphekiwe awakhiqizi i-aflatoxin ngaphansi kwezimo ezijwayelekile, njengoba i-aflatoxin ikhiqizwa kakhulu yizikhunta ezifana ne-Aspergillus flavus ezindaweni ezinomswakama ophezulu nokushisa okuphezulu. Indawo eqandisiwe (cishe -18°C) ayikuvumeli ukukhula kwesikhunta," kusho uWu Jia, iPhini likaNobhala-Jikelele weGatsha Lokufunda Nokudla le-Chinese Health Promotion and Education Association. Uma ama-buns aphekiwe kakade angcoliswe yisikhunta ngaphambi kokubanda, ubuthi besikhunta ngeke bususwe noma ngabe buqandisiwe. Ngakho-ke, ama-buns aphekiwe aqandisiwe asanda futhi angabunjwa ngaphambi kokubanda angadliwa ngokuzethemba. Uma ama-buns aphekiwe anephunga elingavamile, ukushintsha kombala, noma ubuso obungavamile ngemva kokuncibilika, kufanele alahlwe ukuze kugwenywe ukudliwa.
Ngokusho kwe-"Nutrition and Food Hygiene," i-aflatoxin iyi-metabolite ekhiqizwa yi-Aspergillus flavus kanye ne-Aspergillus parasiticus, okuyi-fungi evamile kokusanhlamvu kanye nokudla. E-China, i-Aspergillus parasiticus ayivamile. Izinga lokushisa le-Aspergillus flavus lokukhula nokukhiqiza i-aflatoxin liyi-12°C kuya ku-42°C, kanti izinga lokushisa elihle kakhulu lokukhiqizwa kwe-aflatoxin liyi-25°C kuya ku-33°C, kanye nenani elifanele lomsebenzi wamanzi liyi-0.93 kuya ku-0.98.
I-Aflatoxin ikhiqizwa kakhulu yizikhunta ezindaweni ezifudumele nezinomswakama. Ukuthatha izinyathelo zokuphepha empilweni yansuku zonke kunganciphisa ngempumelelo ingozi yokuchayeka nokugwinya i-aflatoxin. Ochwepheshe batusa ukukhetha izinhlobo nabathengisi abadumile lapho uthenga ukudla ukuqinisekisa ukuthi kusha futhi kuphephile. Lapho kugcinwa ukudla, kufanele kunakwe isikhathi sokuphelelwa yisikhathi, futhi ukudla kufanele kugcinwe endaweni eyomile, enomoya omuhle, nemnyama ukuze kuncishiswe ithuba lokukhula kwesikhunta. Kubaluleke kakhulu ukuqaphela ukuthi ukugcina ukudla esiqandisini akuyona indlela efanelekile, njengoba ukudla kunezikhathi zokugcina ezifanele. Ngesikhathi sokucubungula nokupheka ukudla, ukudla kufanele kugezwe kahle, futhi kufanele kunakwe izindlela zokupheka.
Ngaphezu kwalokho, ngenxa yokuqina okuhle kokushisa kwe-aflatoxin, ayiboli kalula ngokupheka nokushisa okuvamile. Ukudla okukhuntile kufanele kugwenywe, futhi noma ngabe ingxenye ekhuntile isusiwe, okusele akufanele kudliwe. Ngaphezu kwalokho, ukuqwashisa ngokuphepha kokudla kufanele kuthuthukiswe, futhi izinto zasekhishini ezifana nezinti zokusika namabhodi okusika kufanele zihlanzwe ngokushesha futhi zishintshwe njalo ukuze kuvinjelwe ukukhula kwesikhunta namagciwane.
Ngokuphathelene nokugcinwa kwesayensi kwama-buns aphekiwe ngomusi, uWu Jia uthe ukugcina okuqandisiwe kuyindlela ephephile nenambitheka kangcono. Kodwa-ke, kufanele kuqashelwe ukuthi ama-buns aphekiwe ngomusi kufanele avalwe ezikhwameni zokudla noma epulasitiki ukuze kugwenywe ukuthintana nomoya, kuvinjelwe ukuhwamuka kwamanzi, futhi kugwenywe ukungcoliswa yiphunga. Ama-buns aphekiwe ngomusi angangcoliswanga yisikhunta angadliwa zingakapheli izinyanga eziyisithupha uma egcinwe endaweni eqandisiwe engaphansi kuka-18°C. Endaweni eqandisiwe, angagcinwa usuku olulodwa kuya kwezimbili kodwa futhi kudingeka avalwe ukuze kugwenywe umswakama.
