Munguva pfupi yapfuura, nyaya yechepfu yeflatoxinKukura pamabhunu akabikwa nechando mushure mekuchengetwa kwemazuva anopfuura maviri kwakonzera kunetseka kweveruzhinji. Zvakachengeteka here kudya mabhunu akabikwa nechando? Mabhunu akabikwa nechando anofanira kuchengetwa sei nesainzi? Uye tingadzivirira sei njodzi yekubatwa neaflatoxin muhupenyu hwezuva nezuva? Vatori venhau vakatsvaga humbowo panyaya idzi.
"Mabhanzi akabikwa nechando haaburitse aflatoxin mumamiriro ezvinhu akajairwa, sezvo aflatoxin inonyanya kugadzirwa nefungus dzakadai seAspergillus flavus munzvimbo dzinopisa zvakanyanya uye dzine hunyoro hwakawanda. Nzvimbo yakachengetwa nechando (inenge -18°C) haina kunaka kuti chakuvhuvhu chikure," akadaro Wu Jia, Mutevedzeri weMunyori Mukuru weNutrition Literacy Branch yeChinese Health Promotion and Education Association. Kana mabhanzi akabikwa nechando atove akasvibiswa nefungus asati aiswa nechando, chepfu yefungus haizobviswi kunyangwe akaomeswa nechando. Saka, mabhanzi akabikwa nechando asina kuumbwa asati aiswa nechando anogona kudyiwa nechivimbo. Kana mabhanzi akabikwa nechando aine hwema husingawanzoitiki, kuchinja kweruvara, kana pamusoro pawo pasina kunaka mushure mekunyunguduka, anofanira kuraswa kuti asadyiwe.
Zvinoenderana ne "Nutrition and Food Hygiene," aflatoxin imhando yemakemikari inogadzirwa neAspergillus flavus neAspergillus parasiticus, idzo dzinowanikwa muzviyo nezvikafu. MuChina, Aspergillus parasiticus haiwanzoitiki. Tembiricha yeAspergillus flavus kuti ikure uye igadzire aflatoxin iri pakati pe12°C kusvika 42°C, tembiricha yepamusoro yekugadzira aflatoxin iri pakati pe25°C kusvika 33°C, uye kukosha kwekushanda kwemvura kuri pakati pe0.93 kusvika 0.98.
Aflatoxin inonyanya kugadzirwa nefungus munzvimbo dzinodziya uye dzine hunyoro. Kutora matanho ekudzivirira muhupenyu hwezuva nezuva kunogona kuderedza njodzi yekusangana neaflatoxin uye kunwa. Nyanzvi dzinokurudzira kusarudza mhando nevatengesi vane mukurumbira pakutenga chikafu kuti uve nechokwadi chekuti chikafu chiri chitsva uye chakachengeteka. Pakuchengeta chikafu, kunofanira kutariswa nguva yekuchichengeta, uye chikafu chinofanira kuchengetwa munzvimbo yakaoma, ine mhepo yakanaka, uye ine rima kuderedza mukana wekukura kwefungus. Zvakakosha kucherechedza kuti kuchengeta chikafu mufiriji haisi nzira isina musoro, sezvo chikafu chine nguva yakakwana yekuchengetedza. Panguva yekugadzira chikafu nekubika, chikafu chinofanira kugezwa zvakanaka, uye kutariswa nzira dzekubika.
Uyezve, nekuda kwekugadzikana kwakanaka kwekupisa kweaflatoxin, haiore nyore nyore nekubika nekudziisa. Chikafu chine chakuvhuvhu chinofanira kudzivirirwa, uye kunyangwe chikamu chine chakuvhuvhu chikabviswa, chasara hachifanirwe kudyiwa. Pamusoro pezvo, ruzivo rwekuchengetedza chikafu runofanira kuwedzerwa, uye midziyo yekicheni yakaita sezvimiti zvekucheka nemapuranga ekucheka inofanira kucheneswa nekukurumidza uye kutsiviwa nguva nenguva kudzivirira kukura kwefungus nemabhakitiriya.
Nezvekuchengetedzwa kwesainzi kwemabhuni anobikwa nemhepo, Wu Jia akataura kuti kuchengetwa nechando ndiyo nzira yakachengeteka uye inonaka zvikuru. Zvisinei, zvinofanira kucherechedzwa kuti mabhuni anobikwa nemhepo anofanira kuvharwa mumabhegi ezvekudya kana mupurasitiki kuti asasangana nemhepo, kudzivirira kupwa kwemvura, uye kudzivirira kusvibiswa nekunhuwa. Mabhuni anobikwa nemhepo asina kusvibiswa nefungus anogona kudyiwa mukati memwedzi mitanhatu kana akachengetwa munzvimbo ine chando iri pasi pe -18°C. Munzvimbo ine chando, anogona kuchengetwa kwemazuva rimwe kusvika maviri asi anofanirawo kuvharwa kuti asanyorove.
