Tau kawg, kuv tuaj yeem muab qhov sib piv tob ntawm carboxymethylcellulose (CMC) thiab xanthan cov pos hniav.Ob leeg feem ntau yog siv nyob rau hauv ntau yam lag luam, tshwj xeeb tshaj yog nyob rau hauv cov khoom noj, tshuaj thiab tshuaj pleev ib ce, ua thickeners, stabilizers thiab emulsifiers.Txhawm rau kom npog cov ncauj lus kom ntxaws, kuv yuav rhuav tshem qhov kev sib piv rau ntau qhov chaw:
1.Chemical qauv thiab cov khoom:
CMC (carboxymethylcellulose): CMC yog ib qho derivative ntawm cellulose, ib txwm tshwm sim polymer nyob rau hauv cov nroj tsuag cell phab ntsa.Carboxymethyl pawg (-CH2-COOH) tau nkag mus rau hauv cov pob txha cellulose los ntawm cov txheej txheem tshuaj.Qhov kev hloov kho no muab cellulose dej solubility thiab txhim kho functionality, ua rau nws haum rau ntau yam kev siv.
Xanthan gum: Xanthan gum yog polysaccharide ua los ntawm fermentation ntawm Xanthomonas campestris.Nws yog tsim los ntawm kev rov ua dua cov piam thaj, mannose, thiab glucuronic acid.Xanthan cov pos hniav yog paub txog nws cov thickening zoo heev thiab stabilizing zog, txawm tias tsawg concentrations.
2. Muaj nuj nqi thiab kev siv:
CMC: CMC yog dav siv los ua cov thickener, stabilizer thiab binder hauv cov khoom noj xws li ice cream, zaub xam lav hnav khaub ncaws thiab khoom ci.Nws kuj yog siv rau hauv cov tshuaj formulations, detergents thiab cov khoom tu tus kheej vim nws viscosity-tsev thiab dej-retaining zog.Hauv daim ntawv thov zaub mov, CMC pab txhim kho kev ntxhib los mos, tiv thaiv syneresis (dej sib cais) thiab txhim kho qhov ncauj.
Xanthan Gum: Xanthan cov pos hniav yog paub txog nws cov thickening zoo heev thiab stabilizing muaj peev xwm nyob rau hauv ntau yam khoom, nrog rau cov kua ntses, hnav khaub ncaws, thiab lwm yam khoom noj siv mis.Nws muab viscosity tswj, khib nyiab tshem tawm thiab txhim kho tag nrho kev ntxhib los mos ntawm cov khoom noj.Tsis tas li ntawd, xanthan cov pos hniav yog siv rau hauv cov tshuaj pleev ib ce, cov kua dej drilling, thiab ntau yam kev lag luam vim nws cov khoom rheological thiab tsis kam mus rau qhov kub thiab pH.
3. Solubility thiab stability:
CMC: CMC yog soluble nyob rau hauv ob qho tib si dej txias thiab kub, tsim ib tug ntshiab los yog me ntsis opaque tov nyob ntawm qhov concentration.Nws nthuav tawm kev ruaj ntseg zoo tshaj pH ntau yam thiab sib haum nrog rau feem ntau lwm cov khoom xyaw.
Xanthan Gum: Xanthan cov pos hniav yog soluble hauv dej txias thiab kub thiab tsim cov kua nplaum.Nws tseem nyob ruaj khov nyob rau ntau yam pH thiab tswj nws txoj haujlwm nyob rau hauv ntau yam kev ua haujlwm, nrog rau qhov kub thiab txias thiab shear rog.
4. Synergy thiab compatibility:
CMC: CMC tuaj yeem cuam tshuam nrog lwm cov hydrophilic colloids xws li guar gum thiab locust taum cov pos hniav los tsim cov nyhuv synergistic thiab txhim khu kev ntxhib los mos thiab ruaj khov ntawm cov khoom noj.Nws yog sib xws nrog feem ntau cov khoom noj additives thiab cov khoom xyaw.
Xanthan cov pos hniav: Xanthan cov pos hniav kuj muaj kev sib txuam nrog cov pos hniav thiab cov pos hniav locust.Nws yog sib xws nrog ntau yam ntawm cov khoom xyaw thiab cov additives uas feem ntau siv rau hauv cov khoom noj thiab cov ntawv thov kev lag luam.
5. Nqi thiab Muaj:
CMC: CMC feem ntau pheej yig dua piv rau xanthan cov pos hniav.Nws yog dav tsim thiab muag los ntawm txawv manufacturers thoob ntiaj teb.
Xanthan Gum: Xanthan cov pos hniav nyiam kim dua CMC vim cov txheej txheem fermentation koom nrog hauv nws cov khoom.Txawm li cas los xij, nws cov khoom tshwj xeeb feem ntau pom zoo rau nws cov nqi siab dua, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov uas yuav tsum tau ua kom zoo dua thiab muaj peev xwm ruaj khov.
6. Kev xav txog kev noj qab haus huv thiab kev nyab xeeb:
CMC: CMC feem ntau lees paub tias muaj kev nyab xeeb (GRAS) los ntawm cov koom haum tswj hwm xws li FDA thaum siv raws li Kev Tswj Xyuas Zoo (GMP).Nws tsis muaj tshuaj lom thiab tsis ua rau muaj kev phom sij loj rau kev noj qab haus huv thaum noj hauv nruab nrab.
Xanthan cov pos hniav: Xanthan cov pos hniav kuj pom tias muaj kev nyab xeeb noj thaum siv raws li qhia.Txawm li cas los xij, qee tus neeg yuav muaj kev tsis xis nyob hauv plab lossis kev ua xua rau xanthan cov pos hniav, tshwj xeeb tshaj yog nyob rau hauv siab.Cov qib kev pom zoo yuav tsum tau ua raws thiab sab laj nrog kws kho mob yog tias muaj kev phiv tshwm sim.
7. Kev cuam tshuam rau ib puag ncig:
CMC: CMC yog muab los ntawm cov khoom siv txuas ntxiv (cellulose), yog biodegradable, thiab yog ib puag ncig tus phooj ywg piv rau hluavtaws thickeners thiab stabilizers.
Xanthan cov pos hniav: Xanthan cov pos hniav yog tsim los ntawm microbial fermentation, uas yuav tsum tau ntau yam kev pab thiab lub zog.Txawm hais tias nws yog biodegradable, cov txheej txheem fermentation thiab cov khoom siv cuam tshuam tuaj yeem muaj qhov cuam tshuam ib puag ncig zoo dua piv rau CMC.
Carboxymethylcellulose (CMC) thiab xanthan cov pos hniav ob leeg muaj qhov tshwj xeeb zoo thiab yog cov khoom muaj txiaj ntsig zoo hauv ntau qhov kev lag luam.Qhov kev xaiv ntawm ob yog nyob ntawm qhov kev thov tshwj xeeb, kev txiav txim siab nqi thiab kev ua raws cai.Thaum CMC paub txog nws txoj kev ua tau zoo, kev ua tau zoo, thiab kev sib raug zoo nrog lwm cov khoom xyaw, xanthan cov pos hniav sawv rau nws cov thickening, stabilizing, thiab rheological zog.Tus nqi siab dua.Thaum kawg, manufacturers yuav tsum ua tib zoo ntsuas cov yam ntxwv no los txiav txim qhov kev xaiv zoo tshaj plaws rau lawv cov khoom.
