Methylcellulose yog cov khoom noj uas nquag muaj additive. Nws yog tsim los ntawm cov pob zeb ntuj los ntawm kev hloov kho tshuaj lom neeg. Nws muaj qhov ruaj khov zoo, cov nyom thiab thickening cov yam ntxwv thiab yog siv dav hauv kev lag luam khoom noj. Raws li cov khoom siv tsim tawm, nws txoj kev nyab xeeb hauv cov zaub mov tau muaj kev txhawj xeeb ntev.
1. Cov khoom thiab cov haujlwm ntawm methylcellulose
Cov qauv molecular ntawm methylcellulose yog raws li covβ-1,4-chav dej qab zib, uas yog tsim los ntawm hloov qee pawg hydroxyl nrog cov pab pawg methoxy. Nws yog soluble nyob rau hauv dej txias thiab tuaj yeem tsim gel rov qab nyob hauv qee yam. Nws muaj cov thickening zoo, emulsification, ncua kev so, kev ruaj khov thiab dej khaws cov khoom siv. Cov haujlwm no ua rau nws siv dav hauv ncuav, ncuav qab zib, dej haus, khoom noj siv mis, cov khoom noj khov thiab lwm cov teb. Piv txwv li, nws tuaj yeem txhim kho kev ntxhib los ntawm cov khob noom cookie thiab ncua kev laus; Nyob rau hauv cov zaub mov khov, nws tuaj yeem txhim kho lub khov-thaw kuj.
Txawm hais tias nws txoj haujlwm ntau yam, methylcellulose nws tus kheej tsis nqus lossis metabolized nyob rau hauv tib neeg lub cev. Tom qab cov kev noj haus hauv, nws yog feem ntau yog cais los ntawm kev zom hauv daim foos, uas ua rau nws pom ncaj qha rau tib neeg lub cev tshwm sim tsawg. Txawm li cas los xij, cov xeeb ceem no kuj muaj aroused tib neeg kev txhawj xeeb tias nws cov kev xav tau ntev yuav cuam tshuam txoj hnyuv noj qab haus huv.
2. Kev ntsuam xyuas kev nyab xeeb thiab kev nyab xeeb kev nyab xeeb
Ntau yam kev tshawb fawb toxicological tau qhia tias methylcellulose muaj zoo biocompatibility thiab tsawg toxicity. Cov txiaj ntsig ntawm kev sim ntsuas mob toxicity qhia tau hais tias nws lub lethal kom dime) tau ntau dua li cov nyiaj siv nyob rau hauv cov zaub mov pa ntxiv, kev nyab xeeb. Hauv kev sim ntev ntev, nas, nas thiab lwm yam tsiaj tsis pom zoo li kev pheej hmoo ntev li carcinogenicity, teratogenicity thiab kev ua me nyuam toxicity.
Tsis tas li ntawd, muaj kev cuam tshuam ntawm methylcellulose rau tib neeg txoj hnyuv tau kuj tau kawm dav. Vim tias nws tsis tau zom thiab nqus tau, methylcellulose tuaj yeem ua rau cov quav yeeb yaj kiab, txhawb txoj hnyuv, thiab muaj qee yam txiaj ntsig hauv kev cem quav. Nyob rau tib lub sijhawm, nws tsis yog fermented los ntawm plab hnyuv muaj, txo txoj kev pheej hmoo ntawm flatulence los yog mob plab.
3. Cov cai thiab cov cai
Kev siv methylcellulose li cov zaub mov ntxiv yog nruj nruj tswj hwm thoob ntiaj teb. Raws li kev ntsuam xyuas ntawm Pab Kws Paub Kev Koom Tes ntawm Cov Khoom Noj Ntxiv (Jecfa) thiab Lub Ntiaj Teb Kev Noj Qab Haus Huv (Adi) ntawm Methylcellulose yog "tsis tau teev tseg ", qhia tias nws muaj kev nyab xeeb siv nyob rau hauv cov tshuaj pom zoo.
Hauv Tebchaws Meskas, Methylcellulose tau teev raws li feem ntau pom tau tias muaj kev nyab xeeb (Gras) los ntawm Asmeskas Cov Khoom Noj thiab Tshuaj (FDA). Hauv European Union, nws tau cais raws li cov zaub mov ntxiv e461, thiab nws qhov kev siv siab tshaj plaws hauv cov khoom noj sib txawv tau hais meej. Nyob rau hauv Suav teb, kev siv methylcellulose kuj tau tswj hwm los ntawm "Lub teb chaws cov zaub mov kev nyab xeeb cov qauv kev siv nyiaj ntxiv rau cov khoom noj khoom haus.
4. Kev txiav txim siab kev nyab xeeb hauv kev siv
Txawm hais tias tag nrho kev nyab xeeb ntawm methylcellulose kuj muaj qhov siab, nws daim ntawv thov hauv cov zaub mov tseem xav tau them sai sai rau cov ntsiab lus hauv qab no:
Qhov ntsuas: Ntau dhau ntxiv yuav hloov cov kev ntxhib los mos ntawm cov zaub mov thiab cuam tshuam cov khoom zoo nkauj; Nyob rau tib lub sijhawm, ntau dhau ntawm cov tshuaj uas muaj fiber-fiber ntau yuav ua rau mob plab lossis mob plab me me tsis xis nyob.
Lub hom phiaj cov neeg: Rau cov tib neeg uas tsis muaj zog plab hnyuv ua haujlwm (xws li cov me nyuam yaus lossis menyuam yaus tsis muaj peev xwm ua rau lub sijhawm luv luv, yog li nws yuav tsum tau xaiv nrog ceev faj.
Kev sib cuam tshuam nrog lwm cov khoom xyaw: hauv qee cov khoom noj khoom haus, me me methylcellulose yuav muaj cov nyhuv synergistic nrog lwm cov khoom xyaw lossis cov khoom xyaw yuav tsum tau txiav txim siab.
5. Cov ntsiab lus thiab Outlook
Nyob rau hauv dav dav,methylcellulose yog cov zaub mov muaj kev nyab xeeb thiab siv tau zoo uas yuav tsis tsim kev puas tsuaj loj rau tib neeg kev noj qab haus huv nyob rau hauv ib qho kev siv uas muaj. Nws tsis-nqus cov khoom ua rau nws muaj peev xwm ruaj khov hauv lub plab thiab tuaj yeem coj qee yam txiaj ntsig kev noj qab haus huv. Txawm li cas los xij, thiaj li yuav ua kom nws muaj kev nyab xeeb ntxiv, nws yog ib qho tsim nyog los them cov ntaub ntawv muaj feem cuam tshuam nrog cov ntaub ntawv tshwj xeeb, tshwj xeeb tshaj yog nws cov lus qhia tshwj xeeb.
Nrog rau kev txhim kho ntawm kev lag luam khoom noj khoom haus thiab kev txhim kho ntawm cov neeg siv khoom siv 'kev thov rau cov zaub mov zoo, qhov kev siv me me ntawm methylcellulose txuas ntxiv mus ntxiv. Yav tom ntej, ntxiv daim ntawv thov tshiab yuav tsum tau tshawb txog ntawm kev ua kom muaj kev nyab xeeb rau kev muaj txiaj ntsig zoo rau kev lag luam khoom noj.
