He aha nā mea e pili ana i ka hoʻomau ʻana o ka ʻala?

ʻO ka ʻoihana ʻala a me nā mea ʻono o koʻu ʻāina he ʻoihana kūʻai kūʻai nui a hoʻohui ʻia i ka honua.Aia nā hui ʻala a me nā mea ʻala ma Kina, a ua lawe ʻia aku nā mea ʻala a me nā mea ʻala he nui.Ma hope o 20 mau makahiki o ka hoʻomohala ʻana, ua hilinaʻi koʻu ʻāina i ka ʻono a me ka ʻoihana ʻala i ka hoʻomau ʻana i ka ʻenehana, hoʻomau mau i ka hana ʻana a me ka hana, a ua hoʻokō ka ʻoihana i ka hoʻomohala nui.

ʻOkoʻa nā ʻono ʻenehana mai nā mea ʻono kemika o kēlā me kēia lā a me nā mea ʻai.Hōʻike ʻia nā mea ʻala ʻoihana e ka ʻala ʻala, ke kūpaʻa wela kiʻekiʻe a me ka ʻala lōʻihi.Hoʻohana nui ʻia lākou i loko o nā plastics, rubber, coatings kemikala a me nā inika pena.Hoʻohana ʻia ia e uhi i ka ʻala a hoʻonui i ka ʻala e loaʻa ai kahi wahi kūʻai maikaʻi.

ʻO ka ʻono ʻenehana kahi ʻoihana waiwai maka e kākoʻo ana i nā huahana ʻono.ʻO ka meaʻala ka mea maka no ka hui ʻana i nā mea ʻono;Hoʻohana nui ʻia nā mea ʻono i ka meaʻai, nā mea inu, ka waiʻona, nā paka, nā mea hoʻomaʻemaʻe, nā mea hoʻonaninani, nā niho niho, nā lāʻau lapaʻau, nā meaʻai, nā textiles a me nā ʻoihana ʻili.Ma waho aʻe o ka mea ʻala, ʻo ka nui o ka essence i nā huahana flavored ʻokoʻa he 0.3-3% wale nō, akā he hana koʻikoʻi ia i ka maikaʻi o ka huahana, no laila ua kapa ʻia ka ʻono ʻo ka "ʻuhane" o nā huahana flavored.

Ma lalo o ke alakaʻi ʻana o ka ʻepekema a me ka ʻenehana hou, ua loaʻa i ka noiʻi ʻepekema a me ka hana hoʻonaʻauao o koʻu ʻāina ʻala a me ka ʻoihana ʻono i nā hopena maikaʻi.E lawe i ke kula mua o Shanghai Institute of Technology ma ke ʻano he laʻana, ʻo kāna hoʻomaʻamaʻa ʻana i nā limahana ʻepekema a me ka ʻenehana a me nā hoʻokō ʻepekema a me ka ʻenehana.Ua hoʻokumu ke kula i ke kūlana hoʻomaʻamaʻa talena o "ka hoʻomaʻamaʻa kiʻekiʻe kiʻekiʻe i hoʻohana ʻia i nā talena ʻenehana me ka ʻuhane hou a me ka hiki ke hana, a me nā ʻenekini laina mua maikaʻi loa me ka ʻike honua", a hoʻokumu ʻia "e lawelawe ana i ka hoʻokele waiwai a me ka hoʻomohala kaiāulu, e lawelawe ana i nā ʻoihana kūlanakauhale hou. a me ka lawelawe ʻana i nā ʻoihana liʻiliʻi.

ʻO ka lōʻihi o ka mālama ʻana i ka mea ʻala he 3-15 mau mahina.No ka mea, ʻo nā ʻano ʻala like ʻole ka wikiwiki o ka volatilization i nā huahana like ʻole, e pili ana i ke ʻano a me ke ʻano o ke ʻano ʻala, a ʻo ka ea kahe ka ʻenemi o ka ʻala o ka mea ʻala a me ka pauka ʻala, ua kāwili ʻia ka huahana i hoʻopau ʻia a waiho ʻia i loko o kahi pahu. .Hiki i nā mea hoʻonani a me nā mea hoʻopili ma ka ʻili o ka huahana i hoʻopau ʻia ke hōʻemi i ka volatilization o ka ʻala i ka wā o ka mālama ʻana, a laila e hoʻolōʻihi i ka manawa paʻa o ka huahana.

Hoʻohana ʻia ke kaʻina hana hoʻoheheʻe carbon dioxide no ka unuhi ʻana i ka aila ʻala o ka frangipani i hana ʻia ma Laos.Ma ka manawa like, hoʻohana ʻia ka ʻenehana chromatography-mass spectrometry no ka nānā ʻana i ke ʻano kemika o ka ʻaila volatile, e hāʻawi ana i kahi kumu ʻepekema no ka hoʻomohala piha ʻana a me ka hoʻohana ʻana i ka frangipani.Ma o ka noiʻi hoʻokolohua, ua hoʻoholo ka hui noiʻi ʻepekema i nā kūlana kaʻina no ka supercritical carbon dioxide fluid extraction o ka aila frangipani: extraction pressure 25Mpa, extraction temperature 45°C, separation I pressure 12Mpa, a me ka hoʻokaʻawale I wela 55°C.Ma lalo o kēia mau kūlana, ka awelika hua o ka extract mea 5.8927%, i ka mea i oi aku mamua o ka hua o ka mahu distillation hoao extract o 0.0916%.

Loaʻa i ka mākeke ʻala a me nā mea ʻala o Kina ka mana hoʻomohala nui a me ka wahi mākeke.Ua hoʻokomo a kūkulu ʻia nā ʻoihana ʻoihana kaulana i nā ʻāina ʻē a me nā mea ʻala ma Kina.Me ko lākou kaulana honua a me nā pono ʻenehana, ua noho lākou i ka hapa nui o nā mea ʻono a me nā mea ʻala ma waena o ka mākeke kiʻekiʻe.I ka manawa like, ma hope o nā makahiki o ka hoʻomohala ʻana, ua puka mai nā ʻoihana ʻona pilikino a me nā ʻoihana hana ʻala he nui o nā ʻoihana alakaʻi.Ke hilinaʻi nei i ko lākou ʻike i nā ʻono kūloko, ka maikaʻi o ka huahana paʻa, nā kumukūʻai huahana kūpono, a me nā lawelawe ʻenehana noʻonoʻo, ua lanakila mālie kēia mau ʻoihana pilikino i ka ʻike ʻia o nā mea kūʻai aku waena a kiʻekiʻe, a ua hoʻonui ʻia kā lākou mākeke a me ka ʻike brand i kēlā me kēia lā. .

ʻO ke kūpaʻa wela kiʻekiʻe, ka ʻala ikaika, ka mālama ʻana i ka ʻala lōʻihi, a me nā mea ʻē aʻe. ʻāpana, a me nā mea ʻē aʻe. He mea maʻalahi loa ka hoʻohana ʻana i ke kaʻina hana i nā huahana plastik, i loaʻa i nā huahana plastik kahi hopena paʻa ʻala maikaʻi.

ʻO ka hana ʻana a me ka hoʻomohala ʻana o ka ʻoihana ʻono a me nā mea ʻala e kūpono me ka hoʻomohala ʻana i nā ʻoihana kākoʻo e like me ka ʻoihana, nā mea inu, a me nā kemika i kēlā me kēia lā.ʻO nā hoʻololi wikiwiki i nā ʻoihana o lalo ua hoʻoikaika i ka hoʻomohala mau ʻana o ka ʻoihana ʻono a me ka ʻala, me ka hoʻomaikaʻi mau ʻana i ka maikaʻi o ka huahana, hoʻonui mau i nā ʻano like ʻole, nā huahana a me nā kūʻai.Hoʻonui ʻia kēlā me kēia makahiki.No ka hōʻoia ʻana i ka noi nui o nā ʻoihana i lalo a hoʻolaha i ka hoʻomohala ʻana i ka mākeke huahana mea kūʻai aku, pehea e hoʻolaha ai i ka hoʻololi a me ka hoʻonui ʻana o ka ʻoihana i lilo i pilikia maʻamau no ka ʻoihana.

Ma waho aʻe o nā haole pilikua i nā hui ʻono Kina, ʻo nā ʻoihana mokuʻāina he nāwaliwali kumu noiʻi, haʻahaʻa ʻenehana haʻahaʻa, nā ʻano hoʻokele inflexible, a me ka ʻike lawelawe nāwaliwali, i alakaʻi i ka lohi a i ʻole retrogression i kā lākou wikiwiki hoʻomohala o kēia manawa.Me ka paipai ʻana i nā kulekele aupuni o kēia manawa, ua ulu wikiwiki nā kūlanakauhale a me nā ʻoihana pilikino.Me kā lākou mau hana hana maʻalahi a me nā lawelawe noʻonoʻo, ua lanakila lākou i ka mahalo mai nā mea hoʻohana, a ke hoʻonui mau nei kā lākou mākeke.Eia nō naʻe, no ka hapa nui o nā ʻoihana pilikino, ma muli o ke kumu waiwai waiwai a me ka ʻenehana, ʻike maikaʻi ʻole i ka brand, a me ka maikaʻi ʻole o ka huahana, ua paʻa kēia kūlana i ka hoʻomaka ʻana i ka hoʻohui ʻana i ka ʻoihana a hāʻawi i kumu no nā alakaʻi ʻoihana e lilo i mea nui a ikaika.
