Muva nje, isihloko sei-aflatoxinukukhula kumabhanisi afakwe eqandisiwe ngemuva kokugcinwa izinsuku ezingaphezu kwezimbili kudale ukukhathazeka komphakathi. Ingabe kuphephile ukudla amabhanisi afriziwe? Kufanele agcinwe kanjani amabhanisi ashisiwe ngokwesayensi? Futhi singayivimba kanjani ingozi yokuchayeka kwe-aflatoxin empilweni yansuku zonke? Izintatheli zifune ukuqinisekiswa ngalezi zinkinga.
"Amabhanzi aqandisiwe awakhiqizi i-aflatoxin ngaphansi kwezimo ezijwayelekile, njengoba i-aflatoxin ikhiqizwa ikakhulukazi isikhunta esifana ne-Aspergillus flavus endaweni enezinga lokushisa eliphezulu, enomswakama ophezulu. Indawo eyiqhwa (engaba ngu-18°C) ayikuvumeli ukukhula kwesikhunta, "kusho uWu Jia, iPhini likaNobhala-Jikelele weNutrition Literacy Branch yeChinese Health Promotion and Education Association. Uma amabhanisi ashubile asevele angcoliswa isikhunta ngaphambi kokubanda, ubuthi besikhunta ngeke buqedwe ngisho noma bufriziwe. Ngakho-ke, amabhanisi afriziwe afriziwe asemasha futhi angabunjiwe ngaphambi kokuqhwaza angadliwa ngokuzethemba. Uma amabhanzi anephunga elingavamile, ukushintsha kombala, noma indawo engavamile ngemva kokuncibilika, kufanele alahlwe ukuze agweme ukusetshenziswa.
Ngokusho "kokudla okunomsoco kanye nenhlanzeko yokudla," i-aflatoxin iyi-metabolite ekhiqizwa i-Aspergillus flavus kanye ne-Aspergillus parasiticus, okuyisikhunta esivamile kokusanhlamvu nokudla. E-China, i-Aspergillus parasiticus ayivamile. Izinga lokushisa ukuze i-Aspergillus flavus ikhule futhi ikhiqize i-aflatoxin ingu-12°C kuya ku-42°C, nezinga lokushisa elilungile lokukhiqiza i-aflatoxin liba ngu-25°C kuya ku-33°C, futhi inani elifanele lomsebenzi wamanzi lingu-0.93 kuya ku-0.98.
I-Aflatoxin ikhiqizwa ikakhulukazi isikhunta ezindaweni ezifudumele nezinomswakama. Ukuthatha izinyathelo zokuphepha empilweni yansuku zonke kunganciphisa ngempumelelo ingozi yokuchayeka kanye nokungeniswa kwe-aflatoxin. Ochwepheshe batusa ukukhetha amabhrendi nabathengisi abathembekile lapho uthenga ukudla ukuze kuqinisekiswe ukusha nokuphepha. Lapho ugcina ukudla, kufanele kuqashelwe isikhathi sokuphila kweshalofu, futhi ukudla kufanele kugcinwe endaweni eyomile, enomoya omuhle, nendawo emnyama ukuze kuncishiswe ithuba lokukhula kwesikhunta. Kubaluleke kakhulu ukuqaphela ukuthi ukugcina ukudla esiqandisini akuyona indlela engenangqondo, njengoba ukudla kunezikhathi ezifanele zokugcina. Phakathi nokucubungula nokupheka ukudla, ukudla kufanele kugezwe kahle, futhi kunakekelwe izindlela zokupheka.
Ngaphezu kwalokho, ngenxa yokuqina okuhle kokushisa kwe-aflatoxin, ayiboli kalula ukupheka nokushisa okuvamile. Ukudla okukhuntile kufanele kugwenywe, futhi ngisho noma ingxenye ekhuntile isusiwe, okusele akufanele kudliwe. Ukwengeza, ukuqwashisa ngokuphepha kokudla kufanele kuthuthukiswe, futhi izitsha zasekhishini njengezinti namapulangwe okusika kufanele zihlanzwe ngokushesha futhi kushintshwe njalo ukuze kuvinjelwe ukukhula kwesikhunta namagciwane.
Mayelana nokugcinwa kwesayensi kwamabhanzi ashubile, uWu Jia uthe isitoreji esiqandisiwe siyindlela ephephe kakhulu nenambitheka kakhulu. Kodwa-ke, kufanele kuqashelwe ukuthi ama-buns ane-steamed kufanele afakwe uphawu ezikhwameni zokudla noma ukugoqwa kwepulasitiki ukuze kugwenywe ukuthintana nomoya, kuvimbele ukuhwamuka kwamanzi, nokugwema ukungcoliswa yiphunga. Amabhanzi anesitimu angangcoliswa isikhunta angadliwa phakathi nezinyanga eziyisithupha uma egcinwe endaweni eyiqhwa engaphansi kuka-18°C. Endaweni enefriji, zingagcinwa usuku olulodwa kuya kwezimbili kodwa futhi zidinga ukuvalwa ukuze zigweme umswakama.
