Ko Hōngongoi te tihi o te raumati, ā, i ngā raumati wera me te makuku, ka taea e te kai te noho hei wāhi momona mō ngā huakita i ngā wā katoa. Ina koa ko ngā hua me ngā huawhenua, ki te kore ngā hua me ngā huawhenua hou e rongoatia ki roto i te pouaka whakamātao, ka taea anake te rongoa mō te kotahi rā. Ā, i ia raumati, he maha ngā take o te mate korere i puta mai i te "kai kino", i ngā pakeke me ngā tamariki, he maha ngā wā ka pohehetia he kai "makariri rawa". Inaa, ko ngā kai, ko ngā inu rānei i te pāmahana iti ka tere ake te nekeneke o te puku o ētahi hoa, engari i te nuinga o te wā kāore e meinga te tangata kia oma ki te wharepaku i ngā wā maha i te rā. Nō reira, i tēnei wā, ko te mea tuatahi hei whakaaro ko te mate puku i puta mai i te akuaku kai. Kei te pirau, kei te pirau rānei te kai e kainga ana? Nō reira, me pēhea tātou e kai ai i ngā hua me ngā huawhenua hou i te raumati wera?
I tēnei wā, ko te mea tuatahi e whakaarohia ana e tātou ko te rokiroki i roto i te pouaka whakamātao. Heoi, he maha ngā momo kai me ngā inu e rongoatia ana i roto i ngā pouaka whakamātao, i roto i ēnei he maha ngā kai e "wero ana i ngā huakita" ki roto i ngā pouaka whakamātao, pērā i ngā hua manu e kawe ana i te salmonella, me te mīti mata, ngā hua me ngā huawhenua e kawe ana i te Escherichia coli mate, te Staphylococcus aureus mate me ngā pirinoa. Ā, he wā roa anō hoki tō te pouaka whakamātao hei tiaki. I te nuinga o te wā, me kai ngā kai e 2-3 rā te roa, ki te kore ka pirau i roto i te pouaka whakamātao i roto i te wā. I taua wā anō, he wāhi rokiroki anō hoki tō te pouaka whakamātao, e whakamahia ana mō te whakamahinga o te whare anake. Mena he hūpermakete nui, me pēhea te pupuri i te kai kia hou mai i ngā kaihokohoko pūtake e hokona ana e tātou?
I te whanaketanga o te ao ōhanga o te ao whānui, kua noho te kawemai me te kaweake o ngā hua me ngā huawhenua hei tikanga noa. I roto i tēnei āhuatanga, me ako tātou i tētahi momo matū tiaki hou — te matū tiaki hua me te huawhenua 1-MCP. I te whanaketanga o te hua, i tino manakohia. Nā te mea he matū tiaki kore paitini tēnei, he tino haumaru, ā, he tino whai hua. Muri iho, me kōrero tātou mō ngā kai o te matū tiaki hua me te huawhenua 1-MCP.
He aha te 1-Methylcyclopropene?
1-Methylcyclopropene, i whakarāpopototia ko 1-MCP i te reo Pākehā,CAS 3100-04-7Ko te tātai matū ko C4H6. I raro i te pāmahana me te pēhanga noa, he hau kore tae te āhua, kāore he paitini, kāore hoki he reka, ko te mātotorutanga he 0.838g/cm3. He matū Cyclopropene tino kaha. Ko te 1-Methyl Cyclopropene te mea e whakamahia whānuitia ana hei kaiwhakahaere tipu, ā, e whakamahia whānuitia ana i roto i te mara o te tiaki tipu. He painga ōna ko te iti o te whakamahinga, te pai o te pānga tiaki me te haumaru teitei.
Ngā Āhuatanga o te 1-MCP
Ka taea e te 1-MCP te aukati i te tukunga o te ethylene e ngā tipu anō, me te aukati hoki i te here o te ethylene ki ngā kaiwhakawhiwhi e pā ana ki roto i ngā pūtau tipu, ā, ka aukati i te pānga pakari o te ethylene. Nō reira, mā te whakamahi i te 1-Methylcyclopene ka taea te whakaroa i te tukanga pakari me te koroheketanga o ngā tipu, ā, ka whakaroa i te roa o te oranga o ngā hua, ka whakaiti i te pirau me te para i te wā e kawe ana me te rokiroki ana, ā, ka whakaroa i te roa o te oranga o ngā taonga.
Ngā tono o te 1-MCP
1-MCPka taea te whakamahi hei tiaki i ngā hua, huawhenua, me ngā putiputi hei ārai i te memenge o ngā tipu. Hei tauira, ina whakamahia ki ngā hua me ngā huawhenua pēnei i te aporo, te pea, te paramu, te kiwifruit, me te tōmato, ka taea te whakaroa i tō rātou pakari, te whakaiti i te mimiti wai, me te pupuri i tō rātou pakeke, te reka, me te hanganga kai; Mō te tiaki putiputi, ka taea te pupuri i te tae me te kakara o ngā putiputi. Hei tāpiri, ka taea hoki e te 1-Methylcyclopene te whakapai ake i te ātete ki ngā mate tipu.1-Methylcyclopenehe tohu hou tēnei i roto i te tiaki huarākau me huawhenua i muri i te tiakitanga o te āhuarangi whakarerekētia.
I muri i te mate urutā, ka ora ake te ōhanga, ā, ka tipu haere te whanaketanga o te hokohoko o te ao. I ia tau, ka whakaputahia e ia whenua he maha o ngā hua me ngā huawhenua hou o te rohe. Nā te koretake o te whanaketanga o ngā mahi kawe hua ahuwhenua makariri, tata ki te 85% o ngā hua me ngā huawhenua i whakamahi i ngā mahi kawe hua noa, ā, he maha ngā mate pirau i puta, ā, i whakarato hoki i tētahi wāhi mākete whānui mō te whakatairanga me te tono o1-methyl CyclopropeneNō reira, ka kitea he whānui ngā tūmanakohanga whanaketanga o te 1-MCP, ehara i te mea mō ngā momo hua me ngā huawhenua manawa-roa anake, engari ka taea hoki te whakaroa i te rokiroki me te roa o te wā e rongoa ai i muri i te kotinga, inā koa mō ngā hua me ngā huawhenua e pāngia ana e te ethylene, ā, ka taea hoki te pupuri i te kounga taketake o ngā hua me ngā huawhenua mō te wā roa.
