Ua hiki mai ke kauwela, a ʻo ka mea pōʻino loa i nā mea a pau, ʻo ia ka mālama ʻana i ka meaʻai. Pehea e hōʻoia ai i ka hou o ka meaʻai i lilo i kumuhana wela i kēia mau lā. No laila pehea mākou e mālama ai i nā huaʻai hou a me nā mea kanu i ke alo o ke kauwela wela? I mua o kēia kūlana, i nā makahiki i hala iho nei, ua ʻike ʻia ka noiʻi ʻepekema i kahi mea hoʻopale kūpono o ka hana ethylene -1-MCP. ʻAʻole ʻona wale nō ka mea hoʻonāuki 1-MCP, ʻaʻohe pōʻino, koena ʻole, a me ka ʻoluʻolu, akā hoʻohana nui ʻia no ka mālama ʻana i nā huaʻai, nā mea kanu, a me nā pua. Ma lalo, e hoʻolauna mākou i nā kikoʻī kikoʻī o ka huahana 1-MCP.

He aha ka 1-MCP?

1-MCP, i ʻike ʻia ʻo 1-Methylcycloprotene,CAS 3100-04-7. ʻO ka 1-MCP he mea hoʻopaneʻe ethylene maikaʻi e hiki ke kāohi i ke ʻano o ka physiological a me ka biochemical reactions e pili ana i ka oʻo ʻana o ka hua i hoʻoulu ʻia e ka ethylene, keʻakeʻa i ka hanu ʻana o ka mea kanu, hoʻopaneʻe maikaʻi i ka oʻo ʻana o nā hua a me ka holomua ʻelemakule, mālama i ke ʻano kumu a me ka maikaʻi o nā huaʻai a me nā mea kanu. i ka manawa lōʻihi, e hoʻemi i ka hoʻoheheʻe wai, e hoʻohaʻahaʻa i ka pōʻino pathological a me ka palaho microbial, No ka mālama ʻana i ka maikaʻi o ka mālama ʻana i ka hua. A ʻo 1-MCP ʻaʻohe mea ʻawaʻawa a me ke koena manuahi, e hālāwai me nā hōʻailona like ʻole o ka mālama wikiō ʻāina, a hiki ke hoʻohana me ka hilinaʻi.

Ma mua o ka ho'ohana 'ana i ka 1-MCP, ua ho'ohana 'ia ka hapa nui o ka mālama 'ana a me ka mālama 'ana i ke kino: 1. ka mālama 'ana i ka wela ha'aha'a, 2. ka mālama 'ana i ka lewa, a me ka mālama 'ana i ka wela, ka māmā a me ka microwave. Eia naʻe, pono kēia mau ʻano ʻekolu i ka nui o nā limahana a me nā kumuwaiwai, a lōʻihi ka manawa a pōkole. Ua hōʻike ʻia ka noiʻi hiki i ka 1-MCP ke hoʻokūkū maikaʻi i ka hoʻopaʻa ʻana i nā mea hoʻokipa ethylene, e lohi ana i ka oʻo ʻana o ka hua a me ka ʻelemakule. Ma muli o kāna mau mea ʻawaʻawa ʻole, hoʻohana haʻahaʻa, hoʻohana kiʻekiʻe, a me nā waiwai kemika paʻa, i kēia manawa ua hoʻohana nui ʻia i ka mālama ʻana i nā huaʻai a me nā mea kanu, me ka hoʻohana kiʻekiʻe o ka mākeke a me ka helu hoʻolaha.

ʻAʻole ʻo 1-MCP wale nō ke kāohi a hoʻopaneʻe paha i ka hiki ʻana mai o ka ʻelemakule physiological i nā mea kanu, akā he haʻahaʻa haʻahaʻa. ʻO LD50>5000mg/kg he mea ʻawaʻawa ʻole; He haʻahaʻa loa ka manaʻo i hoʻohana ʻia, a i ka wā e hoʻoponopono ai i nā huaʻai, nā mea kanu, a me nā pua, pono ka nui o ka lewa i hoʻokahi miliona miliona, no laila ʻo ke koena o nā huaʻai, nā mea kanu, a me nā pua ma hope o ka hoʻohana ʻana he haʻahaʻa loa ʻaʻole hiki ke ʻike ʻia. ; Ua hala pū ʻo 1-MCP i ka nānā ʻana o ka US Environmental Protection Agency (EPA pūnaewele hoʻolaha) a ua manaʻo ʻia he palekana a ʻaʻole ʻona, kūpono no ka hoʻohana ʻana i nā pua a me nā huaʻai a me nā mea kanu, a palekana no nā kānaka, nā holoholona, ​​​​a me ke kaiapuni. ʻAʻole pono e hoʻokumu i nā palena dosage i ka wā e hoʻohana ai.

He aha ka manaʻo o ka mākeke no 1-MCP?

No nā ʻāina mahiʻai, hana ʻia ka nui o nā huaʻai hou a me nā mea kanu i kēlā me kēia makahiki. Ma muli o ka hoʻomohala kūpono ʻole o ka logistic kaulahao no nā huahana mahiʻai, ma kahi o 85% o nā huaʻai a me nā meaʻai e hoʻohana i ka logistic maʻamau, e hopena i ka nui o ka pala a me ka nalowale. Hāʻawi kēia i kahi ākea ākea no ka hoʻolaha ʻana a me ka noi ʻana o 1-methylcyclopropene. Hōʻike nā hopena noiʻi hiki i ka 1-methylcyclopropene ke hōʻemi nui i ka palupalu a me ka pala o nā huaʻai a me nā mea kanu, a hoʻonui i ko lākou ola papa a me ka manawa mālama. Hoʻopau kēia i ka hoʻokomo ʻana o1-MCP. Inā makemake ʻoe e ʻike hou aku e pili ana i ka huahana, e ʻoluʻolu e waiho iaʻu i kahi leka.
