Hoʻolauna

Ke nānā ʻoe i ka meaʻai a i ʻole ka lepili hōʻailona, ​​hiki ke ʻike ʻoe i nā mea hoʻohui āu i lohe ʻole ai. ʻAʻole hiki paha iā ʻoe ke ʻōlelo aʻe. ʻOiai paha he mea kānalua paha kekahi o kēia mau mea a kānalua paha ʻoe, palekana kekahi poʻe ʻē aʻe, a ʻo kā lākou inoa wale nō ke waiho nei.

ʻO ka silikone dioxide kekahi o ia ʻano. Loaʻa ia i nā huahana he nui, ʻoiai kuhi hewa ʻole ʻia.

He aha kēīa?

Dioxide silikone (SiO₂), ʻike ʻia ʻo silica, kahi hui kūlohelohe i hana ʻia i ʻelua mau mea waiwai nui o ka honua: silicon (Si) a me oxygen (ʻO₂).

Hoʻomaopopo pinepine ʻia ka silicon dioxide i ke ʻano o ka quartz. ʻIke maʻamau ia i ka wai, nā mea kanu, nā holoholona, ​​a me ka honua. ʻO ka pahu honua he 59 pākēneka silica. Hana ʻia ma kahi o 95 pākēneka o nā pōhaku i ʻike ʻia ma ka honua. Ke noho ʻoe ma kahakai, ʻo ka dioxide silikone i ke ʻano o ke one e loaʻa ma waena o kou manamana wāwae.

Loaʻa maoli ia i nā mākele o ke kino o ke kanaka. ʻOiai maopopo ʻole ke ʻano o kāna hana, manaʻo ʻia ia he nutrient pono e pono ai ko mākou kino.

No ke aha i loko o ka meaʻai a me nā mea hoʻopiha?

ʻIke maʻamau ka silicon dioxide i nā mea kanu he nui, e like me:

• lau lau ʻōmaʻomaʻo
• beets
• pepa bele
• laiki palaunu
• ʻoka
• alfalfa

Hoʻohui pū ʻia ka silikone dioxide i nā meaʻai a me nā mea hoʻohui. Ma ke ʻano he mea hoʻohui meaʻai, lawelawe ia ma ke ʻano he mea anticaking e pale i ka ʻōpala ʻana. I nā pākuʻi, hoʻohana ʻia ia e pale i nā mea kūpona i ka paʻa like ʻana.

E like me ka nui o nā mea hoʻohui meaʻai, hopohopo pinepine nā mea kūʻai aku e pili ana i ka silicon dioxide ma ke ʻano he mea hoʻohui. Eia nō naʻe, manaʻo nui nā noiʻi ʻaʻohe kumu o kēia hopohopo.

He aha ka ʻōlelo a ka noiʻi?

ʻO ka ʻoiaʻiʻo o ka silicon dioxide i loaʻa i nā mea kanu a me ka wai inu e hōʻike nei he palekana. Ua hōʻike ʻia ka noiʻi ʻaʻole hiki i ka silica a mākou e ʻai nei ma o kā mākou papaʻai ke hōʻiliʻili i loko o kā mākou kino. Akā, ua holoi ʻia e ko mākou puʻupaʻa.

Eia nō naʻe, hiki ke hana ʻia ka silicosis maʻi maʻi pinepine mai ka inhalation mau o ka lepo silica. Kū pinepine kēia hōʻike a me ka maʻi i waena o ka poʻe e hana nei:

• hoʻouku mining
• kukulu hale
• ʻeli ʻana
• ka ʻoihana kila
• one-loa

ʻOiai ka hapa nui o nā noiʻi e pili ana i ka silica i hana ʻia i nā holoholona, ​​ʻaʻole i loaʻa i nā mea noiʻi kahi pilina ma waena o ka mea hoʻohui meaʻai silicon dioxide a hoʻonui i ka makaʻu o ka maʻi ʻaʻai, nā ʻino, a me ka make. Hoʻohui ʻia, ʻaʻole i loaʻa i kahi noiʻi nā hōʻike e hiki i ka silicon dioxide ma ke ʻano he mea hoʻohui i ka meaʻai ke hoʻopili i ke olakino hānau, kaupaona hānau, a i ʻole ke kino.

Ua hoʻomaopopo pū ka US Food and Drug Administration (FDA) i ka silicon dioxide ma ke ʻano he mea hoʻohui meaʻai palekana. I ka makahiki 2018, ua koi aku ka European Security Food Authority i ka European Union e hoʻokau i nā alakaʻi ʻoi loa ma ka silicon dioxide a hiki i ka noiʻi hou ʻana. Ua kālele ʻia ko lākou hopohopo i nā kinona nunui (ʻo kekahi o lākou i ʻoi aku ka liʻiliʻi ma mua o 100 nm).

Ma mua nā alakaʻi i ukali ʻia i kahi pepa 1974 i hoʻomākaukau ʻia me ka hui pū me ka World Health Organization. Ua loaʻa kēia pepa i nā hopena olakino maikaʻi ʻole e pili ana i ka silikone dioxide i hopena ʻia e ka hemahema silikone. Ke loli nei paha ka noiʻi hou o kēia manawa i nā alakaʻi a me nā ʻōlelo aʻoaʻo.

Ua hoʻonohonoho ʻia nā palena palekana?

ʻOiai ke noiʻi nei i kēia manawa ʻaʻohe nui nā pilikia e pili ana i ka lawe ʻana o ka silicon dioxide, ua kau ka FDA i nā palena kiʻekiʻe ma luna o kāna ʻai ʻana: ʻaʻole pono ʻo Silicon dioxide e ʻoi aku i ka 2 pākēneka o ka nui o ke kaupaona. ʻO ka mea nui kēia no ka mea ʻaʻole i lawa ka nānā ʻia ʻana o nā palena i hoʻonohonoho ʻia.

ʻO ka lawe lawe ʻana

Noho kūlohelohe ka silicon dioxide ma waena o ka honua a me ko mākou kino. ʻAʻohe mea i hōʻike ʻia e hōʻike he mea weliweli ke komo ʻana ma ke ʻano he mea hoʻohui meaʻai, akā ʻoi aku ka nui o ka noiʻi e pili ana i ka hana o ke kino. Hiki i ka inhalation mau o ka lepo silica ke alakaʻi i ka maʻi maʻi.

ʻO ka poʻe i loaʻa i nā maʻi āpau koʻikoʻi ka hoihoi i ka ʻike ʻana he aha nā mea hoʻohui i nā meaʻai a lākou e ʻai ai. Akā ʻoiai inā ʻaʻohe ou mau maʻi ʻino, ʻoi aku ka maikaʻi e akahele me nā mea hoʻohui meaʻai. A ʻo nā loli liʻiliʻi paha i nā pae o nā minelala hiki i kahi hopena hohonu i ka hana olakino. ʻO kahi ala maikaʻi e ʻai i nā meaʻai āpau a loaʻa i nā pae olakino olakino silikone.
