Ua hiki mai ke kauwela, a ʻo ka mea huikau loa no nā mea āpau, ʻo ia ka mālama ʻana i ka meaʻai. Pehea e hōʻoia ai i ka hou o ka meaʻai ua lilo i kumuhana wela i kēia mau lā. No laila pehea mākou e mālama ai i nā huaʻai a me nā mea kanu hou i ke kauwela wela? I ke alo o kēia kūlana, i nā makahiki i hala iho nei, ua ʻike ka noiʻi ʻepekema i kahi mea hoʻopaʻa pono i ka hana ethylene -1-MCP. ʻAʻole wale ka mea hoʻopaʻa 1-MCP ʻaʻole ia he mea ʻawahia, ʻaʻohe mea ʻino, ʻaʻohe koena, a he aloha i ke kaiapuni, akā hoʻohana nui ʻia no ka mālama ʻana i nā huaʻai, nā mea kanu, a me nā pua. Ma lalo nei, e hoʻolauna mākou i nā kikoʻī kikoʻī o ka huahana 1-MCP.
He aha ka 1-MCP?
1-MCP, i ʻike ʻia hoʻi ʻo 1-Methylcycloprotene,CAS 3100-04-7. He mea hoʻopale ethylene kūpono ʻo 1-MCP e hiki ke kāohi i kahi moʻo o nā hopena physiological a me biochemical e pili ana i ka pala ʻana o nā hua i hoʻoulu ʻia e ka ethylene, kāohi i ka ikaika o ka hanu ʻana o nā mea kanu, hoʻopaneʻe pono i ka pala ʻana o nā hua a me ka holomua o ka ʻelemakule, mālama i ke ʻano mua a me ka maikaʻi o nā huaʻai a me nā mea kanu no ka manawa lōʻihi, hōʻemi i ka mahu wai, hōʻoluʻolu i ka pōʻino pathological a me ka pala microbial, E mālama i ka maikaʻi o ka mālama ʻana o nā hua. A ʻaʻohe ʻawaʻawa a me ke koena o 1-MCP, e hoʻokō ana i nā ʻano hōʻailona like ʻole o nā mea mālama wikiō aupuni, a hiki ke hoʻohana ʻia me ka hilinaʻi.

Noi 1-MCP
Ma mua o ka hoʻohana ʻana o 1-MCP, ua hoʻohana ʻia ka hapa nui o nā ʻano hana mālama kino a me ka mālama ʻana: 1. ka hoʻomaʻalili haʻahaʻa wela, 2. ka mālama ʻana i ka lewa i kāohi ʻia, a me 3. ka wela, ka mālamalama, a me ka mālama ʻana i ka microwave. Eia nō naʻe, pono kēia mau ʻano hana ʻekolu i ka nui o ka hana kanaka a me nā kumuwaiwai, a he lōʻihi a pōkole ka manawa. Ua hōʻike ʻia e ka noiʻi hiki i ka 1-MCP ke hoʻokūkū maikaʻi e hoʻopaʻa i nā mea loaʻa ethylene, e hoʻopaneʻe ana i ka pala ʻana o ka hua a me ka ʻelemakule ʻana. Ma muli o kona mau waiwai ʻawaʻawa ʻole, ka hoʻohana haʻahaʻa, ka pono kiʻekiʻe, a me nā waiwai kemika paʻa, hoʻohana nui ʻia i kēia manawa i ka mālama ʻana i nā huaʻai a me nā mea kanu, me ka hoʻohana kiʻekiʻe o ka mākeke a me ka hoʻolaha ʻana.
ʻAʻole wale ka 1-MCP e kāohi a hoʻopaneʻe paha i ka hanana o ka ʻelemakule physiological i nā mea kanu, akā he haʻahaʻa hoʻi ka ʻawahia. ʻO LD50>5000mg/kg he mea ʻawahia ʻole ia; Haʻahaʻa loa ka nui i hoʻohana ʻia, a i ka wā e hana ai i nā huaʻai, nā mea kanu, a me nā pua, ʻo ka nui i ka lewa e pono ai he hoʻokahi miliona wale nō, no laila ʻo ke koena o nā huaʻai, nā mea kanu, a me nā pua ma hope o ka hoʻohana ʻana ua haʻahaʻa loa ia a ʻaʻole hiki ke ʻike ʻia; Ua hala pū ʻo 1-MCP i ka nānā ʻana o ka US Environmental Protection Agency (hoʻolaha pūnaewele EPA) a ua manaʻo ʻia he palekana a ʻaʻohe ʻawahia, 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. ʻAʻohe pono e hoʻokumu i nā kapu dosage i ka wā e hoʻohana ai.
He aha ka nānā ʻana o ka mākeke no 1-MCP?
No nā ʻāina mahiʻai, nui nā huaʻai a me nā mea kanu hou i hana ʻia i kēlā me kēia makahiki. Ma muli o ka hoʻomohala kūpono ʻole o ka logistics kaulahao anu no nā huahana mahiʻai, ma kahi o 85% o nā huaʻai a me nā mea kanu e hoʻohana ana i ka logistics maʻamau, e hopena ana i ka nui o ka palaho a me ka pohō. Hāʻawi kēia i kahi ākea o ka mākeke no ka hoʻolaha a me ka hoʻohana ʻana o 1-methylcyclopropene. Hōʻike nā hopena noiʻi hiki i ka 1-methylcyclopropene ke hōʻemi nui i ka palupalu a me ka palaho o nā huaʻai a me nā mea kanu, a hoʻolōʻihi i ko lākou ola papa a me ka manawa mālama. Hoʻopau kēia i ka hoʻolauna ʻana o1-MCPInā makemake ʻoe e ʻike hou aʻe e pili ana i ka huahana, e ʻoluʻolu e waiho mai iaʻu i kahi leka.
