ʻO Carboxymethyl Cellulose (CMC) he mea nui i hoʻohana ʻia i ka wai-soluble polymer compound i hoʻohana nui ʻia i ka meaʻai, nā lāʻau lapaʻau, nā kemika i kēlā me kēia lā, nā lole a me nā ʻano ʻē aʻe. I ka ʻoihana meaʻai, ʻo kekahi o nā hoʻohana koʻikoʻi o CMC he mea mānoanoa. ʻO nā mānoanoa kahi papa o nā mea hoʻohui e hoʻonui i ka viscosity o kahi wai me ka ʻole o ka hoʻololi nui ʻana i nā waiwai ʻē aʻe o ka wai.
1. ʻO ka hana kemika a me ka mānoanoa o ka carboxymethyl cellulose
ʻO Carboxymethylcellulose he mea ia o ka cellulose i hana ʻia ma ka hoʻololi ʻana i kahi hapa o nā pūʻulu hydroxyl (-OH) o cellulose me nā hui carboxymethyl (-CH2COOH). ʻO kāna ʻāpana kumu kumu he kaulahao hou o β-D-glucose. Hāʻawi ka hoʻokomo ʻana o nā hui carboxymethyl i ka CMC hydrophilicity, hāʻawi iā ia i ka solubility maikaʻi a me ka hiki ke mānoanoa i ka wai. Hoʻokumu nui ʻia kona mānoanoa mānoanoa ma luna o nā kumu aʻe:
Ka hopena o ka pehu: E pehu ka CMC ma hope o ka hoʻopili ʻana i nā molekule wai i loko o ka wai, e hana ana i kahi ʻōnaehana pūnaewele, i hopu ʻia nā mole wai i loko o kona ʻano, e hoʻonui ana i ka viscosity o ka ʻōnaehana.
Ka hopena o ka uku: E hoʻokaʻawale ʻia nā pūʻulu carboxyl i CMC i loko o ka wai no ka hoʻoulu ʻana i nā koina maikaʻi ʻole. ʻO kēia mau pūʻulu i hoʻopiʻi ʻia e hana i ka electrostatic repulsion i loko o ka wai, e hoʻoneʻe ana i nā kaulahao molekala a hana i kahi hopena me ka viscosity kiʻekiʻe.
Ka lōʻihi o ke kaulahao a me ka noʻonoʻo: ʻO ka lōʻihi o ke kaulahao a me ka hoʻonā ʻana o nā molekala CMC e hoʻopilikia i kona hopena mānoanoa. ʻO ka ʻōlelo maʻamau, ʻoi aku ka kiʻekiʻe o ke kaumaha molekala, ʻoi aku ka nui o ka viscosity o ka hopena; i ka manawa like, ʻoi aku ka kiʻekiʻe o ka neʻe ʻana o ka hopena, piʻi pū ka viscosity o ka ʻōnaehana.
Molecular cross-linking: Ke hoʻoheheʻe ʻia ka CMC i loko o ka wai, ma muli o ka hoʻopili ʻana ma waena o nā molekala a me ka hoʻokumu ʻana o kahi ʻano pūnaewele, ua kaupalena ʻia nā molekala wai i nā wahi kikoʻī, e hopena i ka emi ʻana o ka wai o ka hopena, no laila e hōʻike ana i kahi hopena mānoanoa.
2. Hoʻohana i ka carboxymethyl cellulose i ka ʻoihana meaʻai
I ka ʻoihana meaʻai, hoʻohana nui ʻia ka carboxymethylcellulose ma ke ʻano he mānoanoa. Eia kekahi mau hiʻohiʻona noi maʻamau:
Nā mea inu a me nā huahana waiu: I nā wai huaʻai a me nā mea inu lactobacillus, hiki i ka CMC ke hoʻonui i ka viscosity o ka mea inu, hoʻomaikaʻi i ka ʻono a hoʻolōʻihi i ke ola. ʻOi aku i nā mea momona haʻahaʻa a momona ʻole, hiki iā CMC ke pani i kahi ʻāpana o ka momona o ka waiū a hoʻomaikaʻi i ke ʻano a me ka paʻa o ka huahana.
ʻO nā kīʻaha a me nā mea ʻono: I loko o ka ʻaʻahu saladi, ka ʻuala tōmato a me ka soy sauce, hana ʻo CMC ma ke ʻano he mānoanoa a me ka mea hoʻomaha e hoʻomaikaʻi ai i ka like ʻana o ka huahana, pale i ka delamination, a hoʻoikaika i ka huahana.
ʻO Ice cream a me nā mea inu anu: ʻO ka hoʻohui ʻana i ka CMC i ka ice cream a me nā mea inu anu hiki ke hoʻomaikaʻi i ke ʻano o ka huahana, e ʻoi aku ka denser a me ka elastic, e pale ana i ka hoʻokumu ʻana o nā kristal hau a hoʻomaikaʻi i ka ʻono.
ʻO ka berena a me nā huahana i kālua ʻia: I loko o nā huahana i kālua ʻia e like me ka berena a me nā keke, hoʻohana ʻia ʻo CMC ma ke ʻano he mea hoʻomaikaʻi i ka palaoa e hoʻonui ai i ka hoʻonui ʻia o ka palaoa, e hoʻomāmā i ka berena, a hoʻolōʻihi i ke ola o ka papa.
3. Nā noi mānoanoa ʻē aʻe o carboxymethyl cellulose
Ma waho aʻe o ka meaʻai, hoʻohana pinepine ʻia ka carboxymethylcellulose ma ke ʻano he mānoanoa i nā lāʻau lapaʻau, nā mea hoʻonaninani, nā kemika i kēlā me kēia lā a me nā ʻoihana ʻē aʻe. ʻo kahi laʻana:
ʻOihana lāʻau lapaʻau: I nā lāʻau lapaʻau, hoʻohana pinepine ʻia ʻo CMC e hoʻomāpopo i nā syrups, capsules, a me nā papa, i ʻoi aku ka maikaʻi o nā lāʻau lapaʻau i ka hoʻoheheʻe ʻana a me nā hopena disintegration, a hiki ke hoʻomaikaʻi i ke kūpaʻa o nā lāʻau.
ʻO nā mea hoʻonani a me nā kemika i kēlā me kēia lā: I nā mea hoʻohana i kēlā me kēia lā e like me ka niho niho, ka shampoo, ka gel wai, a me nā mea ʻē aʻe, hiki i ka CMC ke hoʻonui i ka kūlike o ka huahana, hoʻomaikaʻi i ka ʻike hoʻohana, a hana i ka paʻi paʻa a paʻa.
4. Ka palekana o ka carboxymethyl cellulose
Ua hōʻoia ʻia ka palekana o ka carboxymethylcellulose e nā haʻawina he nui. No ka loaʻa ʻana o ka CMC mai ka cellulose kūlohelohe a ʻaʻole ʻeli ʻia a komo ʻia i loko o ke kino, ʻaʻohe hopena maikaʻi ʻole i ke olakino kanaka. ʻO ka World Health Organization (WHO) a me ke Kōmike Kūkākūkā Hui no nā meaʻai meaʻai (JECFA) hoʻokaʻawale iā ia ma ke ʻano he meaʻai palekana. Ma ke kumu kūpono, ʻaʻole hana ʻo CMC i nā hopena ʻawaʻawa a loaʻa kekahi mau lubrication a me nā hopena laxative ma ka ʻōpū. Eia nō naʻe, hiki i ka hoʻohana nui ʻana ke hōʻeha i ka ʻōpū o ka ʻōpū, no laila e mālama pono ʻia nā ʻano meaʻai i kuhikuhi ʻia i ka hana ʻai.
5. Nā pono a me nā pōʻino o ka carboxymethylcellulose
Loaʻa iā Carboxymethylcellulose kona mau pono a me nā palena ma ke ʻano he mānoanoa:
Nā Pōmaikaʻi: Loaʻa i ka CMC ka hiki ke hoʻoheheʻe wai maikaʻi, ke kūpaʻa wela a me ke kūpaʻa kemika, he ʻakika a me ka alkali, a ʻaʻole hiki ke hoʻohaʻahaʻa ʻia. ʻAe kēia e hoʻohana ʻia i nā ʻano hana hana like ʻole.
Nā pōʻino: hiki i ka CMC ke lilo i ʻeleʻele loa i nā kiʻekiʻe kiʻekiʻe a ʻaʻole kūpono i nā huahana āpau. E hoʻohaʻahaʻa ʻia ka CMC i kahi kaiapuni ʻakika, e hoʻemi ana i kona hopena mānoanoa. Pono e akahele i ka hoʻohana ʻana ia mea i nā mea inu ʻawaʻawa a i ʻole nā meaʻai.
Ma ke ʻano he mānoanoa koʻikoʻi, hoʻohana nui ʻia ka carboxymethylcellulose i ka meaʻai, ka lāʻau lapaʻau, nā mea hoʻonaninani a me nā ʻano ʻē aʻe ma muli o kona hoʻoheheʻe wai maikaʻi, mānoanoa a paʻa. ʻO kona hopena mānoanoa maikaʻi a me ka palekana e lilo ia i mea hoʻohui maʻamau i ka ʻoihana hou. Eia nō naʻe, pono ka hoʻohana ʻana i ka CMC e hoʻokele ʻepekema e like me nā pono kikoʻī a me nā kūlana dosage e hōʻoia i ka optimization o kāna hana a me ka palekana o ka meaʻai.
