Carboxymethyl cellulose (CMC) ndi chilengedwe chachilengedwe, chomwe chimagwiritsidwa ntchito kwambiri mu chakudya, mankhwala, zodzoladzola, zodzola mafuta ndi minda ina. Monga chowonjezera chowonjezera, CMC ili ndi kukula kwamphamvu, kukhazikika, kapangidwe ka filimu, kunyowa ndi zinthu zina. Poyerekeza ndi ena okulitsa, mawonekedwe apadera a CMC ndi katundu amapangitsa kuti zikhale zofunikira pazinthu zambiri.
1. Kapangidwe ka mankhwala
Carboxymethyl cellulose
Carboxymethyl cellulose ndi ma cellulose ether ether opangidwa ndi kuyambitsa magulu a carboxymethyl mu cellulose yachilengedwe mutatha kuyamwa. Chipinda chake choyambirira ndi glucose, ndipo carboxymethyl amalowa m'malo mwa magulu a hydroxyl (-Oh) mu cellouse kuti apange boaxymethyl bond bond (-O-cooh). Kapangidwe kameneka kamapangitsa cmc kukhala wosungunuka kwambiri m'madzi ndi mitundu yabwino.
Otsatsa ena
Xanthan chingamu: xanthan chingamu ndi cholemera kwambiri polysarde wopangidwa ndi nandomomonas. Tcheni lake lalikulu limapangidwa ndi β-ducan, ndipo maunyolo ake am'mbali ali ndi mannose, glucuronic acid, etc. xanthan chingamu chimakhala ndi mawonekedwe owoneka bwino.
Guar Gum: Guar chingamu chimachotsedwa pa endospermm wa nyemba za Guar ndipo ndi za galactomannan. Tsitsani lalikulu limapangidwa ndi D-Mannose ndi ulalo wa mbali ndi D-Galactose. Guar Gum imasungunuka mosavuta m'madzi ozizira ndikupanga mawonekedwe apamwamba kwambiri.
Pectin: Pectin ndi polysacide yomwe ilipo m'makoma a cell, makamaka opangidwa ndi galacturonic acid, ndipo digiri yake ya Methoxyty imakhudza katundu wake. Percnin ali ndi gel yokhala ndi gel okhala ndi zigawo za acidic.
Hydroxypropyll methylcellulose (hpmc): hpmc): hpmc ndikuchotsa methylcelulose ndi hydroxypropyfypropyficy ndi meth. HPMC ili ndi zosungunuka bwino komanso zokutira m'madzi.
2. Makina a Thictism
Carboxymethyl cellulose
CMC itasungunuka m'madzi, gulu la carboxymethyl limapangitsa kuti likhale ndi hydrophilicity yabwino, ndikulumikizana ndi mamolekyulu amadzi ndikupanga zingwe za hydrogen ndi amphamvu. Njira yake yokulirapo imawonjezera mawonekedwe a yankho kudzera mu kukopeka ndi mamolekyulu. Kuphatikiza apo, CMC ili ndi kukhazikika kwa acidic kapena alkalinine ndipo imagwiritsidwa ntchito kwambiri m'makhalidwe omwe ali ndi mfundo zosiyanasiyana.
Otsatsa ena
Xanthan chingamu: Xanthan chingamu chimawonjezera mafayilo a yankho kudzera pachimake ndi ntchito ya haidrogeni ya mamolekyulu a nthawi yayitali. Katundu wake wapadera wamasunguwo umapangitsa kuchepa kwa ma vinyapo kuti achepetse mwachangu akamagwera mphamvu, ndikubwezeretsanso chidwi chachikulu mukakhazikika.
Guar Gum: Guar Sum imawonjezera mafayilo a yankho popanga netiweki yolumikizidwa ndi kutupa ndi mayamwidwe amadzi. Makina ake olerera amatha kupanga dongosolo lowoneka bwino la colloidal.
Pectin: Pectin amapanga zomangira za hydrogen ndi mamolekyulu amadzi kudutsa magulu a carboxyl a ma unyolo am'mbali. Itha kupanga network ya gel ndi calcium ion pansi mumikhalidwe acidic, ndikuwonjezera mafayilo a yankho.
Hydroxypypyl methylcellulose (hpmc imawonjezera mafayilo a yankho kudzera mu mamolekyulu ndi mapangidwe a hydrogen. Kusungunuka kwake ndi ufa kumasiyana kwambiri pansi pa kutentha kosiyanasiyana, ndipo kumakhala ndi gel ya gel.
3. Kugwiritsa ntchito
Carboxymethyl cellulose
Makampani ogulitsa zakudya: masentimita ambiri amagwiritsidwa ntchito muzakudya monga mkaka, zakumwa, zakumwa, ndi kupanikizana, kukhazikika, molakwika, ndikusintha kapangidwe kake.
Mankhwala: Mu gawo la mankhwala opangira mankhwala, CMC imagwiritsidwa ntchito ngati binder ndi kuwonongeka kwa mapiritsi, ndipo imagwiritsidwanso ntchito mafuta a ophthalmic ndi malo onunkhira.
Zodzikongoletsera: CMC imagwiritsidwa ntchito modzola monga zodzola ndi zowuma, ndipo zimakhala ndi chonyowa komanso kukhazikika ntchito.
Makampani opanga ma petroleum: pakupanga mafuta, cmc amagwiritsidwa ntchito pobowola zamadzimadzi ndi matope kuti athe kukula ndikuchepetsa kuchepa kwa kafukufuku.
Otsatsa ena
Xanthan chingamu: chogwiritsidwa ntchito kwambiri mu chakudya, zodzoladzola, mankhwala opangira mankhwala, makamaka mankhwalawa, makamaka machitidwe, masungu, ndi ma engulsifiers.
Guar Gum: Nthawi zambiri amagwiritsidwa ntchito muzakudya monga ayisikilimu, zinthu zamkaka, ndi mavalidwe a saladi kuti atulutse kwambiri komanso kukhazikika; imagwiritsidwa ntchito ngati thickir ndi Stabilizer mu mafakitale opanga ndi mawonekedwe.
Petcun: Makamaka zakudya monga kupanikizana, ma jellies, ndi maswiti ofewa, chifukwa cha gels acidic ndi malo okhala acidic.
Hydroxypropyl methylcelulose yokonzekera mankhwala, zopangira zomangira, zowonjezera zakudya, ndi zina zowonjezera, makamaka m'matanthwe a matenthedwe.
3. Chitetezo
Carboxymethyl cellulose
CMC imawonedwa ngati chakudya chotetezeka ndikukumana ndi zikhalidwe zachitetezo cha chakudya cha mayiko ambiri. Zomwe zimagwiritsidwa ntchito zikugwirizana ndi malamulo, CMC siyopanda zoopsa ku thupi la munthu. Zimaonetsanso kuti zinthu zabwino komanso zopanda pake zikagwiritsidwa ntchito ngati mankhwala opatsa thupi komanso cosmetic.
Otsatsa ena
Xanthan chingamu: Monga chowonjezera cha chakudya, xanthan chingamu nthawi zambiri chimawoneka chotetezeka, koma Mlingo waukulu ungayambitse vuto la m'mimba.
Guar Gum: Ilinso chakudya chowonjezera chakudya, koma kudya kwambiri kumayambitsa matenda osokoneza bongo monga kutuluka.
Pectin: Nthawi zambiri ankaganiza zotetezeka, koma zingasokoneze mavuto.
Hydroxypropyl methylcellulose (monga chowonjezera cha mankhwala ophatikizika komanso chowonjezera, hpmc ali ndi chitetezo chabwino, koma mlingo wake uyenera kutsatira malamulo oyenera.
Carboxymethyl cellulose imawonetsa maulendo ake apadera poyerekeza ndi otuwa ena, kuphatikizapo kusungunuka kwamadzi abwino, kusinthasintha kwamadzi komanso kugwiritsa ntchito mitundu ingapo. Ngakhale okulitsa ena atha kukhala ndi zabwino m'malo mwa mahatchi, monga kugwetsa misempha ya xanthan chingamu ndi gelc katundu wa pectin, cmc akadali ndi malo abwino kwambiri. Mukamasankha Thicker, ndikofunikira kuti tiwone zomwe zikuchitika monga kukula kwamphamvu, malo ogwiritsira ntchito ndi chitetezo kuti mukwaniritse zabwino.
