Cellulose etherCov khoom siv derivatives tau siv dav hauv kev lag luam zaub mov tau ntev. Kev hloov kho lub cev ntawm cellulose tuaj yeem tswj hwm cov khoom rheological, hydration thiab microstructure ntawm lub cev. Tsib lub luag haujlwm tseem ceeb ntawm cov tshuaj hloov kho cellulose hauv zaub mov yog rheology, emulsification, ua npuas ncauj ruaj khov, lub peev xwm los tswj cov dej khov crystal tsim thiab loj hlob, thiab dej khi.
Xyoo 1971, Pawg Neeg Saib Xyuas Kev Sib Koom Tes rau Cov Khoom Noj Khoom Haus ntawm WHO tau lees paub tias microcrystalline cellulose yog ib yam khoom noj khoom haus ntxiv. Hauv kev lag luam khoom noj, microcrystalline cellulose feem ntau yog siv ua emulsifier, ua npuas dej stabilizer, ua kom kub siab stabilizer, ua kom puv tsis muaj as-ham, ua kom tuab, ua kom ncua, ua kom haum thiab tswj cov dej khov ua kom siv lead ua. Thoob ntiaj teb, muaj kev siv microcrystalline cellulose hauv kev tsim cov khoom noj khov thiab dej haus txias qab zib thiab cov kua ntses ua noj; Siv microcrystalline cellulose thiab nws cov khoom carboxylated ua cov khoom ntxiv los tsim cov roj zaub xas lav, cov rog mis nyuj thiab cov khoom qab zib dextrin; Thiab cov ntawv thov cuam tshuam hauv kev tsim cov khoom noj khoom haus zoo thiab tshuaj rau cov neeg mob ntshav qab zib.
Cov noob siv lead ua ke hauv 0.1 ~ 2 microns ntawm microcrystalline cellulose rau qib colloidal, colloidal microcrystalline cellulose tau qhia los ntawm txawv teb chaws tus stabilizer rau kev tsim khoom noj mis nyuj, raws li muaj kev ruaj khov zoo thiab saj, yog siv ntau dua hauv kev tsim cov dej haus zoo, feem ntau yog siv rau cov mis nyuj calcium siab, mis nyuj cocoa, mis nyuj walnut, mis nyuj txiv laum huab xeeb, thiab lwm yam. Thaum cov colloidal microcrystalline cellulose thiab carrageenan siv ua ke, kev ruaj khov ntawm ntau cov mis nyuj tsis muaj zog tuaj yeem daws tau.
Methyl cellulose (MC)los yog cov nroj tsuag hloov kho cellulose gum thiab hydroxyprolyl methyl cellulose (HPMC) ob leeg tau ntawv pov thawj ua cov khoom noj khoom haus ntxiv. Ob leeg muaj cov dej num ntawm qhov chaw thiab tuaj yeem hydrolyzed hauv dej thiab yooj yim ua ib zaj duab xis hauv cov kua, uas tuaj yeem decomposed rau hauv hydroxyprolyl methyl cellulose methoxy thiab hydroxyprolyl Cheebtsam los ntawm cua sov. Methyl cellulose thiab hydroxyprolyl methyl cellulose muaj roj saj, tuaj yeem qhwv ntau lub npuas, nrog rau kev ua haujlwm khaws cia noo noo. Siv rau hauv cov khoom ci, khoom noj txom ncauj khov, kua zaub (xws li cov pob khoom noodle tam sim ntawd), kua txiv hmab txiv ntoo thiab cov khoom qab zib hauv tsev neeg. Hydroxypropyl methyl cellulose yog dej-soluble, tsis zom los ntawm tib neeg lub cev lossis txoj hnyuv microbial fermentation, tuaj yeem txo cov roj cholesterol, kev noj mus sij hawm ntev muaj cov txiaj ntsig ntawm kev tiv thaiv kev mob ntshav siab.
CMC yog carboxymethyl cellulose, Tebchaws Meskas tau suav nrogCMCHauv Tebchaws Meskas Txoj Cai Lij Choj, tau lees paub tias yog ib yam khoom muaj kev nyab xeeb. Lub Koom Haum Khoom Noj thiab Ua Liaj Ua Teb ntawm United Nations thiab Lub Koom Haum Kev Noj Qab Haus Huv Ntiaj Teb tau lees paub tias CMC muaj kev nyab xeeb, thiab kev noj txhua hnub ntawm tib neeg yog 30m g / kg. CMC muaj cov khoom sib txuas tshwj xeeb, thickening, suspension, stability, dispersion, water retention, cementitious. Yog li ntawd, CMC hauv kev lag luam khoom noj khoom haus tuaj yeem siv ua thickening agent, stabilizer, suspension agent, dispersant, emulsifier, wetting agent, gel agent thiab lwm yam khoom noj khoom haus additives, tau siv hauv ntau lub tebchaws.
