Methylcellulose (MC)musanganiswa unobva ku cellulose uye unoshandiswa zvakanyanya mukudya, mushonga, zvizorwa uye mamwe maindasitiri. Iyo inonyungudika nemvura selulosi kubva kune imwe thickening, gelling, emulsification, kumiswa uye zvimwe zvivakwa.
Kemikari zvivakwa uye nzira dzekugadzira dzemethylcellulose
Methylcellulose inowanikwa nekuita cellulose (iyo huru yemaitiro chikamu muzvirimwa) ine methylating agent (yakadai semethyl chloride, methanol, nezvimwewo). Kuburikidza nemethylation reaction, iyo hydroxyl boka (-OH) ye cellulose inotsiviwa neboka remethyl (-CH3) kugadzira methylcellulose. Chimiro chemethylcellulose chakafanana neicho chepakutanga cellulose, asi nekuda kwekuchinja kwayo kwemaitiro, inogona kunyungudika mumvura kuti iite viscous solution.
Iyo solubility, viscosity uye gelling zvimiro zvemethylcellulose zvine hukama zvakanyanya nezvinhu zvakaita sedhigirii remethylation uye molecular uremu. Zvinoenderana nezvinodiwa zvakasiyana, methylcellulose inogona kugadzirwa kuva mhinduro dzeviscosities dzakasiyana, saka ine huwandu hwakasiyana hwekushandisa mumaindasitiri akasiyana.
Kunyanya kushandiswa kwemethylcellulose
Indasitiri yezvokudya
Muindasitiri yezvekudya, methylcellulose inonyanya kushandiswa seyakakora, stabilizer, emulsifier uye gelling agent. Semuenzaniso, muzvokudya zvakaderera kana zvisina mafuta, methylcellulose inogona kutevedzera kuravira kwemafuta uye inopa maitiro akafanana. Inowanzoshandiswa kugadzira chikafu chakagadzirira-kudya, chikafu chakaomeswa nechando, zvihwitsi, zvinwiwa, uye mapfekero esaladhi. Uye zvakare, methylcellulose inowanzoshandiswa mune yezvinomera kana chirimwa-yakavakirwa nyama inotsiva sechinhu chinowedzera kubatsira kunatsiridza kuravira uye magadzirirwo.
Pharmaceutical Uses
Muindasitiri yemishonga, methylcellulose inowanzoshandiswa sechinhu chinobatsira kugadzira zvinodhaka, kunyanya zvinodzorwa zvinoburitsa zvinodhaka. Inogona kuburitsa zvinodhaka zvishoma nezvishoma mumuviri, saka methylcellulose inowanzoshandiswa semutakuri mune mamwe anodzorwa zvinodhaka kuburitswa kwemishonga. Pamusoro pezvo, methylcellulose inoshandiswawo kugadzirira misodzi yekugadzira kubatsira kubata matambudziko emaziso akadai seakaoma maziso.
Cosmetics uye Personal Care Zvigadzirwa
Methylcellulose inoshandiswa seyakakora, inosimbisa, uye inonyorovesa muzvizoro, uye inowanzoshandiswa muzvigadzirwa zvakaita semafuta ekuzora, makirimu, uye shampoos. Inogona kuwedzera viscosity uye kugadzikana kwechigadzirwa, zvichiita kuti chigadzirwa chive nyore kana chikashandiswa.
Industrial Uses
Methylcellulose inoshandiswawo zvakanyanya mukuvaka, kunyanya simende, machira, uye zvinonamira, semukobvu uye emulsifier. Inogona kuvandudza kunamatira, fluidity, uye kushanda kwechigadzirwa.
Kuchengetedzwa kwemethylcellulose
Methylcellulose ikemikari inoonekwa seyakachengeteka. World Health Organisation (WHO) neUS Food and Drug Administration (FDA) vese vanozviona sekuwedzera kwenjodzi. Methylcellulose haina kugayiwa mumuviri uye semvura inonyungudika yekudya fiber, inogona kuburitswa zvakananga kuburikidza nemuura. Naizvozvo, methylcellulose ine yakaderera chepfu uye hapana kukuvadza kuri pachena kumuviri wemunhu.
Migumisiro pamuviri wemunhu
Methylcellulose kazhinji haina kunyura mumuviri. Inogona kubatsira kukurudzira intestinal peristalsis uye kubatsira kubvisa matambudziko ekuvimbiswa. Sekudya fiber, ine basa rekunyorovesa uye kuchengetedza matumbo, uye inogona kutogadzirisa mazinga ehuga. Zvisinei, kudya kukuru kwemethylcellulose kunogona kukonzera kusagadzikana kwepamuviri, zvakadai se flatulence kana manyoka. Naizvozvo, zvakakosha kushandisa huwandu hwakakodzera hwemethylcellulose kana uchiishandisa sekuwedzera.
Mhedzisiro paallergic constitutions
Kunyange zvazvo methylcellulose pachayo isingawanzoita zvinokonzerwa nemagetsi, vamwe vanhu vane hanya vanogona kunge vane hunyoro husina kunaka kune zvigadzirwa zvine methylcellulose. Kunyanya mune zvimwe zvizorwa, kana chigadzirwa chacho chine zvimwe zvinhu zvinogumbura, zvinogona kukonzera kukanganiswa kweganda. Naizvozvo, zvakanakisa kuita bvunzo yemunharaunda usati washandisa.
Zvidzidzo zvekushandisa kwenguva refu
Parizvino, zvidzidzo zvekugara kwenguva refu kwemethylcellulose hazvina kuwana kuti zvichakonzera matambudziko makuru ehutano. Nhamba huru yezvidzidzo zvakaratidza kuti methylcellulose, kana yakashandiswa sezvokudya zvefiber supplement, ine chimwe chinhu chakanaka pakuvandudza kuvimbiswa uye kukurudzira hutano hwematumbo.
Sezvokudya zvakachengeteka uye kuwedzera kwezvinodhaka, methylcellulose inoshandiswa zvakanyanya mumaindasitiri akawanda, kusanganisira zvokudya, mishonga, zvizorwa, nezvimwewo. Kazhinji hazvikuvadzi kumuviri womunhu, uye kana zvichishandiswa zvine mwero, zvinogona kutounza humwe hutano hwehutano, hwakadai sekuvandudza hutano hwematumbo uye kubvisa kuvimbiswa. Zvisinei, kunwa zvakanyanya kunogona kukonzera kusagadzikana kwepamuviri, saka kunofanira kushandiswa zvine mwero. Kazhinji, methylcellulose chinhu chakachengeteka, chinoshanda uye chinoshandiswa zvakanyanya.
