ʻO Iulai ka piko o ke kauwela, a i nā kauwela wela a pulu, hiki i ka meaʻai ke lilo i wahi momona no ka bacteria i kēlā me kēia manawa. ʻOi loa nā huaʻai a me nā mea kanu, inā ʻaʻole mālama ʻia nā huaʻai a me nā mea kanu i kūʻai hou ʻia i loko o ka friji, hiki ke mālama ʻia no hoʻokahi lā wale nō. A i kēlā me kēia kauwela, nui nā hihia o ka maʻi diarrhea i hoʻokumu ʻia e ka "ʻai maikaʻi ʻole", ʻo nā pākeke a me nā keiki, pinepine kuhihewa ʻia no ka ʻai ʻana i ka "anu". ʻO ka ʻoiaʻiʻo, ʻo ka meaʻai a i ʻole nā ​​​​mea inu haʻahaʻa e hoʻoulu ai i kekahi mau hoaaloha e loaʻa ka peristalsis ʻōpū wikiwiki, akā ma ke ʻano laulā ʻaʻole ia e hoʻoulu i ka poʻe e holo i ka lua i nā manawa he nui i ka lā. No laila i kēia manawa, ʻo ka mea mua e noʻonoʻo ai ʻo ia ka maʻi ʻōpū i hoʻokumu ʻia e ka hoʻomaʻemaʻe meaʻai. Ke pala nei a palaho paha ka meaʻai i ʻai ʻia? No laila pehea e hiki ai iā mākou ke ʻai i nā huaʻai a me nā mea kanu hou i ke kauwela wela?

I kēia manawa, ʻo ka mea mua a mākou e noʻonoʻo ai, ʻo ia ka mālama ʻana i loko o ka pahu hau. Eia nō naʻe, he nui nā ʻano meaʻai a me nā mea inu i mālama ʻia i loko o nā pahu hau, a ma waena o ia mau mea he nui nā meaʻai e "hoʻokomo i ka bacteria" i loko o nā pahu hau, e like me nā hua manu e lawe paha i ka salmonella, a me ka ʻiʻo maka, nā huaʻai a me nā mea kanu e lawe paha i ka pathogenic Escherichia coli, pathogenic Staphylococcus aureus a me nā parasites. A he ola papa ko ka pahu hau no ka mālama ʻana. Ma ke ʻano laulā, pono e ʻai ʻia ka meaʻai e hala ana i 2-3 mau lā, inā ʻaʻole e pala i loko o ka pahu hau i ka hala ʻana o ka manawa. I ka manawa like, loaʻa i ka pahu hau kahi nui o ka wahi mālama, kahi i hoʻohana wale ʻia no ka hoʻohana ʻana i ka home. Inā he hale kūʻai nui ia, pehea mākou e mālama ai i ka meaʻai hou mai nā mea kūʻai kumu a mākou e kūʻai ai?

Me ka hoʻomohala ʻana o ka hoʻokele waiwai honua, ua lilo ka lawe ʻana mai a me ka lawe aku ʻana aku i nā huaʻai a me nā mea kanu i mea maʻamau. I ke alo o kēia kūlana, pono mākou e aʻo i kahi ʻano mea mālama hou - 1-MCP mea mālama huaʻai a me nā mea kanu. I ka manawa i hoʻomohala ʻia ai ka huahana, ua loaʻa iā ia ka pane kiʻekiʻe. No ka mea, he mea mālama ʻawaʻawa ʻole kēia, palekana loa, a he mea mālama maikaʻi loa. A laila, e kamaʻilio kākou e pili ana i nā mea hoʻohui o 1-MCP mea mālama huaʻai a me nā mea kanu.

He aha ka 1-Methylcyclopropene?

1-Methylcyclopropene, i hoʻopōkole ʻia e like me 1-MCP ma ka ʻōlelo Pelekania,CAS 3100-04-7ʻO ke ʻano kemika ʻo C4H6. Ma lalo o ka mahana a me ke kaomi maʻamau, he kinoea kala ʻole ke ʻano, ʻaʻohe mea ʻawahia a ʻono ʻole, me ka nui o 0.838g/cm3. He hui Cyclopropene ikaika loa ia. Hoʻohana nui ʻia ka 1-Methyl Cyclopropene ma ke ʻano he mea hoʻoponopono ulu mea kanu a hoʻohana nui ʻia ma ke kahua o ka mālama ʻana i nā mea kanu. Loaʻa iā ia nā pono o ka hoʻohana haʻahaʻa, ka hopena mālama maikaʻi a me ka palekana kiʻekiʻe.

Nā ʻano o 1-MCP

Hiki i ka 1-MCP ke kāohi i ka hoʻokuʻu ʻia ʻana o ka ethylene e nā mea kanu ponoʻī, a ke ālai pū nei hoʻi i ka hoʻopaʻa ʻana o ka ethylene i nā mea loaʻa pili i loko o nā cell mea kanu, a laila e kāohi ana i ka hopena pala o ka ethylene. No laila, ʻo ka hoʻopili ʻana o 1-Methylcyclopene hiki ke hoʻolōʻihi i ke kaʻina hana pala a me ka ʻelemakule o nā mea kanu, a laila e hoʻolōʻihi i ko lākou ola papa, e hōʻemi ana i ka palaho a me ka ʻōpala i ka wā o ka lawe ʻana a me ka mālama ʻana, a e hoʻolōʻihi i ke ola papa o nā waiwai.

Nā noi o 1-MCP

1-MCPhiki ke hoʻopili ʻia i ka mālama ʻana i nā huaʻai, nā mea kanu, a me nā pua e pale aku i ka mae ʻana o nā mea kanu. No ka laʻana, i ka wā e hoʻopili ʻia ai i nā huaʻai a me nā mea kanu e like me nā ʻāpala, nā pea, nā plum, nā kiwifruit, a me nā tōmato, hiki iā ia ke hoʻopaneʻe i ko lākou pala ʻana, hōʻemi i ka mahu ʻana o ka wai, a mālama i ko lākou paʻakikī, ka ʻono, a me ka haku mele ʻana o ka meaʻai; I ke ʻano o ka mālama ʻana i nā pua, hiki iā ia ke mālama i ke kala a me ke ʻala o nā pua. Eia kekahi, hiki i ka 1-Methylcyclopene ke hoʻomaikaʻi i ke kūpaʻa ʻana i nā maʻi o nā mea kanu.1-Methylcyclopenehe hanana koʻikoʻi hou i ka mālama ʻana i nā huaʻai a me nā mea kanu ma hope o ka mālama ʻana i ka lewa i hoʻololi ʻia.

Ma hope o ke ahulau, ua hoʻōla hou ka hoʻokele waiwai, a ua hoʻonui mālie ʻia ka hoʻomohala ʻana o ke kālepa honua. I kēlā me kēia makahiki, e hana ana kēlā me kēia ʻāina i ka nui o nā huaʻai a me nā mea kanu hou kūloko. Ma muli o ka hoʻomohala kūpono ʻole o ka logistics kaulahao anu mahiʻai, ma kahi o 85% o nā huaʻai a me nā mea kanu i hoʻohana i ka logistics maʻamau, e hopena ana i ka nui o nā pohō palaho, kahi i hāʻawi pū i kahi ākea mākeke no ka hoʻolaha a me ka hoʻopili ʻana o1-methyl CyclopropeneNo laila, hiki ke ʻike ʻia he ākea nā manaʻolana hoʻomohala o 1-MCP, ʻaʻole wale no nā huaʻai a me nā mea kanu climacteric hanu like ʻole, akā hiki nō hoʻi ke hoʻolōʻihi i ka mālama ʻana ma hope o ka ʻohi ʻana a me ke ola papa, ʻoi aku hoʻi no nā huaʻai a me nā mea kanu i pili i ka ethylene, a hiki ke mālama i ke ʻano mua o nā huaʻai a me nā mea kanu no ka manawa lōʻihi.
