I waenganui i te piki haere o te kino o ngā take haumaru kai, kua puta he momo kete whakamātautau hou e hangai ana ki teWhakamātautau Ārai Mate Pūmua Hononga-Whākī (ELISA)Kei te haere haere tonu hei taputapu nui i roto i te mara o te whakamātautau haumaru kai. Ehara i te mea ka whakaratohia he huarahi tika ake, he huarahi whai hua ake hoki mō te aroturuki kounga kai, engari ka hangaia hoki he rārangi parepare pakari mō te haumaru o te kai a ngā kaihoko.
Ko te kaupapa matua o te kete whakamātautau ELISA ko te whakamahi i te tauhohenga here motuhake i waenga i te antigen me te paturopi hei whakatau i te nui o ngā matū ūnga i roto i te kai mā te whanaketanga tae o te papa whākōkī. He tino māmā te tukanga whakahaere, ā, he tino motuhake me te aro nui, e taea ai te tautuhi me te ine tika i ngā matū kino i roto i te kai, pērā i te aflatoxin, te ochratoxin A, me teNgā paitini T-2.
Mō ngā tikanga whakahaere motuhake, ko ngā mahi e whai ake nei kei roto i te kete whakamātautau ELISA:
1. Te whakarite tauira: Tuatahi, me tukatuka tika te tauira kai e whakamatautauria ana, pērā i te tango me te purenga, kia whiwhi ai i tētahi otinga tauira ka taea te whakamahi mō te kimi.
2. Tāpiri tauira: Ka tāpirihia te otinga tauira kua tukatukahia ki ngā puna kua tohua i roto i te pereti ELISA, me ia puna e rite ana ki te matū hei whakamātautau.
3. Whakatōngia: Ka whakatongia te pereti ELISA me ngā tauira kua tāpirihia ki te pāmahana e tika ana mō tētahi wā kia taea ai te here katoa i waenga i ngā antigens me ngā antibodies.
4. Te horoi: Whai muri i te whakawhānaungatanga, ka whakamahia te wai horoi hei tango i ngā antigens, i ngā paturopi rānei kāore i herea, hei whakaiti i te pokanoa o te herenga kore-motuhake.
5.Te tāpiri i te papa me te whanaketanga tae: Ka tāpirihia te otinga papa ki ia poka, ā, ka whakahohehia e te whākōkī i runga i te paturopi kua tohua ki te whākōkī te papa kia whanake ai he tae, ka hangaia he hua tae.
6. Ine: Ka inehia te uara mimiti o te hua tae i roto i ia poka mā te whakamahi i ngā taputapu pēnei i te kaipānui ELISA. Kātahi ka tatauhia te ihirangi o te matū hei whakamātautau i runga i te pihi paerewa.
He maha ngā whakamahinga o ngā kete whakamātautau ELISA i roto i ngā whakamātautau haumaru kai. Hei tauira, i te wā o te tirotiro haumaru kai me te tirotiro tauira, i whakamahia e ngā mana whakahaere mākete he kete whakamātautau ELISA hei kimi tere me te tika i ngā taumata nui rawa o te aflatoxin B1 i roto i te hinu pīnati i hangaia e te mira hinu. I tere tonu te tango i ngā whiu tika, ā, i ārai i te matū kino kei tūpono ki ngā kaihoko.
Heoi anō, nā te ngāwari o te whakamahi, te tika, me te pono, e whakamahia whānuitia ana te kete whakamātautau ELISA i roto i ngā whakamātautau haumaru o ngā momo kai pēnei i ngā hua wai, ngā hua mīti, me ngā hua miraka. Ehara i te mea ka whakapoto noa i te wā kimi me te whakapai ake i te whai huatanga, engari ka tautoko hangarau kaha hoki i ngā mana whakahaere kia kaha ake ai te tirotiro i te mākete kai.
I te whanaketanga tonu o te hangarau me te mōhiotanga e piki haere ana ki te haumaru kai i waenga i te tangata, ka nui haere te hiranga o ngā kete whakamātautau ELISA i roto i te mara o te whakamātautau haumaru kai. I ngā rā kei te heke mai, e tumanako ana mātou ki te putanga tonu mai o ngā auahatanga hangarau, e whakatairanga tahi ana i te whanaketanga kaha o te umanga haumaru kai, me te whakarato i tētahi taurangi pakari ake mō te haumaru o te kai a ngā kaihoko.
