ʻO Iulai ke kiʻekiʻe o ke kauwela, a i ka wā wela a me ke kau wela, hiki ke lilo ka meaʻai i mea momona no ka bacteria i kēlā me kēia manawa. ʻOi aku ka nui o nā huaʻai a me nā mea kanu, inā ʻaʻole mālama ʻia nā huaʻai a me nā mea kanu hou i loko o ka friji, hiki ke mālama ʻia no hoʻokahi lā. A i kēlā me kēia kauwela, nui nā maʻi o ka maʻi maʻi ma muli o ka "ʻai maikaʻi ʻole", nā mākua a me nā keiki, kuhi pinepine ʻia no ka ʻai ʻana i ka "anu". ʻO ka ʻoiaʻiʻo, ʻo ka meaʻai a i ʻole nā ​​​​mea inu haʻahaʻa ke kumu e loaʻa ai i kekahi mau hoaaloha ka wikiwiki o ka peristalsis o ka ʻōpū, akā maʻamau, ʻaʻole ia e holo i ka poʻe i ka lumi hoʻomaha i nā manawa he nui i ka lā. No laila, i kēia manawa, ʻo ka mea mua e noʻonoʻo ai ʻo ka maʻi ʻōpū i hoʻokumu ʻia e ka maʻemaʻe meaʻai. He popopo a popopo ka ai i hoopauia? No laila pehea mākou e ʻai ai i nā huaʻai hou a me nā mea kanu i ke kauwela wela?

I kēia manawa, ʻo ka mea mua a mākou e manaʻo ai ʻo ka mālama ʻana i ka friji. 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 e lawe ai i ka salmonella, a me ka ʻiʻo maka, nā huaʻai a me nā mea kanu e hiki ke lawe i ka pathogenic Escherichia coli. pathogenic Staphylococcus aureus a me nā parasites. A loaʻa i ka pahu hau ke ola no ka mālama ʻana. ʻO ka mea maʻamau, pono e ʻai ʻia ka meaʻai i 2-3 mau lā, i ʻole e popopo i loko o ka friji i ka manawa. I ka manawa like, loaʻa i ka friji kekahi wahi o ka waiho ʻana, 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 mai nā kumu kūʻai aku a mākou e kūʻai ai?

Me ka hoʻomohala ʻana o ka honua hoʻokele waiwai, ua lilo ka lawe ʻana a me ka lawe ʻana aku i nā huaʻai a me nā mea kanu i mea maʻamau. I mua o kēia kūlana, pono mākou e aʻo i kahi ʻano mea mālama hou - 1-MCP huaʻai a me nā mea kanu meaʻai. Ke hoʻomohala ʻia ka huahana, loaʻa iā ia kahi pane kiʻekiʻe. No ka mea, he mea ʻawaʻawa ʻole kēia, palekana loa, a ʻoi aku ka maikaʻi o ka mālama ʻana. Ma hope aʻe, e kamaʻilio e pili ana i nā mea hoʻohui o ka 1-MCP huaʻai a me ka mālama mea kanu.

He aha ka 1-Methylcyclopropene?

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

Nā hiʻohiʻona o 1-MCP

Hiki i ka 1-MCP ke kāohi i ka hoʻokuʻu ʻia ʻana o ka ethylene e nā mea kanu ponoʻī, a pale pū i ka hoʻopaʻa ʻana o ka ethylene i nā mea hoʻokipa pili i loko o nā pūnaewele mea kanu, a laila e kāohi ai i ka hopena o ka ethylene. No laila, hiki i ka hoʻohana ʻana o 1-Methylcyclopene ke hoʻolōʻihi i ke kaʻina o ka oʻo ʻana a me ka ʻelemakule o nā mea kanu, a laila e hoʻolōʻihi i ko lākou ola ʻana, e hōʻemi ana i ka palaho a me ka ʻōpala i ka wā o ka lawe ʻana a me ka mālama ʻana, a hoʻolōʻihi i ke ola o nā waiwai.

Nā noi o 1-MCP

1-MCPhiki ke hoʻohana ʻia i ka mālama ʻana i nā huaʻai, nā mea kanu, a me nā pua e pale ai i ka maloʻo o nā mea kanu. No ka laʻana, ke hoʻohana ʻia i nā huaʻai a me nā mea kanu e like me nā ʻāpala, nā pears, nā plums, nā hua kiwi, a me nā ʻōmato, hiki iā ia ke hoʻopaneʻe i ko lākou oʻo ʻana, hoʻemi i ka hoʻoheheʻe ʻana o ka wai, a mālama i ko lākou paʻakikī, ʻono, a me ka meaʻai meaʻai; Ma ke ʻano o ka mālama 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 ka pale ʻana i nā maʻi kanu.1-MethylcyclopeneHe mea hou ia i ka mālama ʻana i nā huaʻai a me nā mea kanu ma hope o ka mālama ʻia ʻana o ka lewa.

Ma hope o ka maʻi ahulau, ua hoʻi hou ka hoʻokele waiwai, a ua ulu mālie ka hoʻomohala ʻana o ke kālepa honua. I kēlā me kēia makahiki, hoʻopuka kēlā me kēia ʻāina i ka nui o nā huaʻai hou a me nā mea kanu. Ma muli o ka hoʻomohala kūpono ʻole o ka logistic kaulahao mahiʻai, ma kahi o 85% o nā huaʻai a me nā huaʻai i hoʻohana i ka logistic maʻamau, e hopena i ka nui o nā poho palaho, kahi i hāʻawi ʻia i kahi ākea ākea no ka hoʻolaha ʻana a me ka noi1-methyl Cyclopropene. No laila, hiki ke ʻike ʻia ʻo 1-MCP ka nui o ka hoʻomohala ʻana, ʻaʻole wale no nā huaʻai climacteric respiratory climacteric a me nā mea kanu, akā hiki ke hoʻolōʻihi i ka mālama ʻana ma hope o ka hōʻiliʻili ʻana a me ke ola ʻana, ʻoi aku hoʻi no nā huaʻai a me nā mea kanu ethylene, a hiki ke mālama i ka mea kumu. ka maikaʻi o nā huaʻai a me nā mea kanu no ka manawa lōʻihi.
