Nō nā tata nei, ko te kaupapa ote aflatoxinKua puta te āwangawanga o te marea mō te tipu haere o ngā parāoa kōhua tio i muri i te pupuri mō ngā rā e rua neke atu. He haumaru te kai i ngā parāoa kōhua tio? Me pēhea te penapena pūtaiao i ngā parāoa kōhua? Ā, me pēhea te ārai i te tūponotanga o te pānga o te aflatoxin i roto i te oranga o ia rā? Kua rapu ngā kairīpoata i te manatoko mō ēnei take.
"Kāore ngā parāoa kōhua tio e whakaputa i te aflatoxin i raro i ngā āhuatanga noa, nā te mea ko te aflatoxin te nuinga e whakaputahia ana e ngā pokepokea ai pērā i te Aspergillus flavus i roto i ngā taiao pāmahana teitei, haumākū teitei. Kāore te taiao tio (tata ki te -18°C) e pai mō te tipu o te pokepokea ai," te kī a Wu Jia, te Hekeretari Tuarua o te Peka Mātauranga Kai o te Rōpū Whakatairanga Hauora me te Mātauranga Hainamana. Mena kua poke kē ngā parāoa kōhua i te pokepokea ai i mua i te tio, e kore e whakakorea ngā paitini pokepokea ai ahakoa kua tio. Nō reira, ka taea te kai me te maia i ngā parāoa kōhua tio hou, kāore anō kia tiohia i mua i te tio. Mena he kakara rerekē, he rerekē te tae, he rerekē rānei te mata o ngā parāoa kōhua i muri i te rewa, me maka atu kia kore ai e kainga.
E ai ki te "Nutrition and Food Hygiene," ko te aflatoxin he matū matū i hangaia e Aspergillus flavus me Aspergillus parasiticus, he harore noa i roto i te witi me te whāngai kararehe. I Haina, he onge noa te Aspergillus parasiticus. Ko te awhe pāmahana mō Aspergillus flavus ki te tipu me te whakaputa aflatoxin ko te 12°C ki te 42°C, ko te pāmahana tino pai mō te whakaputa aflatoxin ko te 25°C ki te 33°C, ā, ko te uara ngohe wai tino pai ko te 0.93 ki te 0.98.
Ko te nuinga o te wā ka puta te aflatoxin i roto i ngā harore i ngā taiao mahana, haumākū hoki. Mā te mahi tupato i ia rā ka taea te whakaiti i te tūponotanga o te pānga me te horomitanga o te aflatoxin. E taunaki ana ngā tohunga kia whiriwhiria ngā waitohu me ngā kaihoko rongonui i te wā e hoko ana i te kai hei whakarite i te hou me te haumaru. I te wā e penapena ana i te kai, me aro ki te roa o te wā e penapena ai, ā, me penapena te kai ki roto i te taiao maroke, pai te hauhautanga, me te pōuri hoki hei whakaiti i te tupono ka tipu te harore. He mea nui kia mōhio ko te penapena kai i roto i te pouaka whakamātao ehara i te tikanga tino pai, nā te mea he pai te wā rokiroki o ngā kai. I te wā e tukatuka ana, e tunu ana hoki i te kai, me horoi pai ngā kai, me aro hoki ki ngā tikanga tunu kai.
Hei tāpiri atu, nā te pai o te pumau o te aflatoxin ki te wera, kāore e ngāwari te pirau i te tunu me te whakamahana noa. Me karo i ngā kai pokepokea ai, ā, ahakoa kua tangohia te wāhanga pokepokea ai, kaua e kainga te toenga. Hei tāpiri atu, me whakanui ake te mōhiotanga ki te haumaru kai, ā, me horoi wawe tonu ngā taputapu kīhini pērā i ngā rākau tapatapahi me ngā papa tapahi, ā, me whakakapi tonu i ia wā hei ārai i te tipu o te pokepokea ai me te huakita.
Mō te rokiroki pūtaiao o ngā parāoa kōhua, i kī a Wu Jia ko te rokiroki tio te mea tino haumaru me te reka. Heoi, me mōhio ko ngā parāoa kōhua me hiri ki roto i ngā putea kai, i te takai kirihou rānei hei karo i te pā ki te hau, hei ārai i te mimiti wai, hei karo hoki i te poke o ngā haunga. Ko ngā parāoa kōhua kāore i poke i te harore ka taea te kai i roto i ngā marama e ono mēnā ka rongoatia ki te taiao tio i raro i te -18°C. I roto i te taiao pouaka whakamātao, ka taea te pupuri mō te kotahi ki te rua rā engari me hiri hoki kia kore ai e makuku.
