Methylcellulose he mea hoʻohui meaʻai maʻamau. Hana ʻia ia mai ka cellulose maoli ma o ka hoʻololi kemika. He kūpaʻa maikaʻi, gelling a me nā waiwai mānoanoa a hoʻohana nui ʻia i ka ʻoihana meaʻai. Ma ke ʻano he mea i hoʻololi ʻia, ʻo kona palekana i ka meaʻai ua lōʻihi ka hopohopo.
1. Nā waiwai a me nā hana o ka methylcellulose
Hoʻokumu ʻia ka molecular structure o ka methylcellulose ma kaβ-1,4-glucose pūʻulu, i hana ʻia ma ka hoʻololi ʻana i kekahi mau pūʻulu hydroxyl me nā hui methoxy. Hiki ke hoʻoheheʻe ʻia i ka wai anuanu a hiki ke hana i kahi gel reversible ma lalo o kekahi mau kūlana. Loaʻa iā ia ka mānoanoa maikaʻi, emulsification, hoʻokuʻu, kūpaʻa a me nā waiwai mālama wai. Hoʻohana nui ʻia kēia mau hana i ka berena, nā pastries, nā mea inu, nā huahana waiu, nā meaʻai paʻa a me nā māla ʻē aʻe. No ka laʻana, hiki iā ia ke hoʻomaikaʻi i ke ʻano o ka palaoa a hoʻopaneʻe i ka ʻelemakule; i nā meaʻai maloʻo, hiki iā ia ke hoʻomaikaʻi i ka pale ʻana i ka hau.
ʻOiai ʻo kāna mau hana like ʻole, ʻaʻole i hoʻopili ʻia ka methylcellulose iā ia iho i loko o ke kino kanaka. Ma hope o ka ʻai ʻana, ua hoʻokuʻu ʻia ma o ka digestive tract i kahi ʻano undecomposed, kahi e hōʻemi ʻia ai kona hopena pololei i ke kino o ke kanaka. Eia nō naʻe, ua hoʻāla ʻia kēia ʻano i ka hopohopo o ka poʻe e pili ana i kāna ʻai lōʻihi i ke olakino ʻōpū.
2. ʻO ka loiloi toxicological a me nā haʻawina palekana
Ua hōʻike ʻia nā haʻawina toxicological he nui ka methylcellulose i ka biocompatibility maikaʻi a me ka haʻahaʻa haʻahaʻa. Ua hōʻike ʻia nā hopena o nā hoʻāʻo ʻona koʻikoʻi ʻoi aku ka kiʻekiʻe o kāna LD50 (median lethal dose) ma mua o ka nui i hoʻohana ʻia i nā mea hoʻohui meaʻai maʻamau, e hōʻike ana i ka palekana kiʻekiʻe. I loko o nā hoʻāʻo ʻawaʻawa lōʻihi, ʻaʻole i hōʻike ʻia nā ʻiole, nā ʻiole a me nā holoholona ʻē aʻe i nā hopena koʻikoʻi ma lalo o ka hānai ʻana i ka wā lōʻihi i nā kiʻekiʻe kiʻekiʻe, me nā pilikia e like me ka carcinogenicity, teratogenicity a me nā mea make hānau.
Eia kekahi, ua aʻo nui ʻia ka hopena o ka methylcellulose ma ka ʻōpū o ke kanaka. No ka mea, ʻaʻole i ʻeli ʻia a hoʻopaʻa ʻia, hiki i ka methylcellulose ke hoʻonui i ka nui o ka wai, hoʻoikaika i ka peristalsis ʻōpū, a loaʻa kekahi mau pono i ka hoʻomaha ʻana i ka constipation. I ka manawa like, ʻaʻole ia e fermented e ka flora intestinal, e hōʻemi ana i ka hopena o ka flatulence a i ʻole ka ʻeha ʻōpū.
3. Nā rula a me nā loina
Hoʻoponopono ʻia ka hoʻohana ʻana i ka methylcellulose ma ke ʻano he meaʻai meaʻai i ka honua holoʻokoʻa. Wahi a ka loiloi o ke Kōmike Hoʻohui Hui no nā Mea Hoʻohui Meaʻai (JECFA) ma lalo o ka Food and Agriculture Organization o United Nations (FAO) a me ka World Health Organization (WHO), ʻaʻole i kuhikuhi ʻia ka intake ʻae ʻia i kēlā me kēia lā (ADI) o ka methylcellulose. ", e hōʻike ana he palekana ke hoʻohana i loko o ka dosage i ʻōlelo ʻia.
Ma ʻAmelika Hui Pū ʻIa, ua helu ʻia ka methylcellulose ma ke ʻano he mea palekana (GRAS) e ka US Food and Drug Administration (FDA). I ka European Union, ua helu ʻia ʻo ia e like me ka meaʻai additive E461, a ʻo kona hoʻohana nui ʻana i nā meaʻai like ʻole i wehewehe ʻia. Ma Kina, ua hoʻoponopono ʻia ka hoʻohana ʻana i ka methylcellulose e ka "National Food Safety Standard Food Additive Usage Standard" (GB 2760), kahi e koi ai i ka mana koʻikoʻi o ka dosage e like me ke ʻano o ka meaʻai.
4. Nā noʻonoʻo palekana i nā noi kūpono
ʻOiai ʻoi aku ka kiʻekiʻe o ka palekana holoʻokoʻa o ka methylcellulose, pono ke hoʻohana ʻia i ka meaʻai i nā mea aʻe:
Ka Hoʻohui: Hiki ke hoʻololi i ke ʻano o ka meaʻai a hoʻololi i ka maikaʻi o ka naʻau; i ka manawa like, hiki i ka ʻai nui ʻana i nā mea fiber kiʻekiʻe ke hoʻoulu i ka ʻōpū a i ʻole ka hōʻeha ʻana i ka digestive.
Ka heluna kanaka i manaʻo ʻia: No ka poʻe me ka nawaliwali o ka ʻōpū (e like me ka poʻe ʻelemakule a i ʻole nā keiki liʻiliʻi), hiki i ka nui o ka methylcellulose ke hoʻoulu i ka ʻai ʻana i ka wā pōkole, no laila pono ke koho ʻia me ka akahele.
Ka pilina me nā mea ʻē aʻe: Ma kekahi mau meaʻai, hiki i ka methylcellulose ke loaʻa ka hopena synergistic me nā mea hoʻohui a i ʻole nā mea hoʻohui ʻē aʻe, a pono e noʻonoʻo ʻia ko lākou mau hopena hui.
5. Hōʻuluʻulu manaʻo a me Outlook
Laulaha,methylcellulose he mea hoʻohui meaʻai palekana a maikaʻi hoʻi ʻaʻole e hōʻeha nui i ke olakino kanaka i loko o kahi ākea kūpono o ka hoʻohana. ʻO kāna mau waiwai hiki ʻole ke hoʻopaʻa ʻia i loko o ka digestive tract a hiki ke lawe mai i kekahi mau pono olakino. Eia nō naʻe, i mea e hōʻoiaʻiʻo ai i kona palekana i ka hoʻohana lōʻihi, pono e hoʻomau i ka nānā ʻana i nā haʻawina toxicological kūpono a me ka ʻikepili hoʻohana pono, ʻoi aku ka hopena i nā heluna kūikawā.
Me ka hoʻomohala ʻana o ka ʻoihana meaʻai a me ka hoʻomaikaʻi ʻana i ka noi o nā mea kūʻai aku no ka maikaʻi o ka meaʻai, hiki ke hoʻonui ʻia ka nui o ka hoʻohana ʻana i ka methylcellulose. I ka wā e hiki mai ana, pono e ʻimi ʻia nā noi hou aʻe ma ke kumu o ka hōʻoia ʻana i ka palekana o ka meaʻai e lawe mai i ka waiwai nui i ka ʻoihana meaʻai.
