Xanthan cov pos hniav

Xanthan gum yog ib hom siv dav siv microbial exopolysaccharide ua los ntawm Xanthomonas rapeseed los ntawm fermentation engineering nrog carbohydrate ua raw khoom (xws li pob kws hmoov txhuv nplej siab). Nws muaj qhov tshwj xeeb rheology, dej solubility zoo, tshav kub thiab acid-base stability, thiab muaj kev sib raug zoo nrog ntau yam ntsev, raws li tus neeg sawv cev thickening, tshem tawm tus neeg sawv cev, emulsifier, stabilizer, tuaj yeem siv dav hauv zaub mov, roj av, tshuaj thiab lwm yam. Ntau tshaj 20 kev lag luam, tam sim no yog lub ntiaj teb loj tshaj plaws kev tsim khoom thiab siv dav siv microbial polysaccharide.

Cov khoom tso saib

Xanthan cov pos hniav yog lub teeb daj rau dawb movable hmoov, me ntsis tsw. Soluble nyob rau hauv dej txias thiab kub, nruab nrab daws, resistant rau khov thiab thawing, insoluble nyob rau hauv ethanol. Disperses nrog dej thiab emulsifies rau hauv ib qho ruaj khov hydrophilic viscous colloid.

Kev lag luam zaub mov:

Xanthan cov pos hniav yog siv dav hauv kev lag luam khoom noj khoom haus, xws li cov khaub ncaws hnav khaub ncaws, khob cij, khoom noj siv mis, khoom noj khov, dej haus, khoom qab zib, khoom qab zib, pastries thiab lwm yam. Nws tuaj yeem tswj tau qhov rheology, qauv, tsw thiab cov tsos ntawm cov khoom, thaum tuav lub saj zoo.

Kev lag luam tshuaj txhua hnub:

Vim tias nws cov molecules muaj ntau pawg hydrophilic, xanthan cov pos hniav feem ntau yog siv los ua ib feem ntawm cov tshuaj txhuam hniav, ua lub luag haujlwm hauv thickening thiab shaping, thiab muaj cov nyhuv ntawm anti-oxidation thiab tiv thaiv kev laus ntawm daim tawv nqaij.

Pharmaceutical kev lag luam:

Xanthan cov pos hniav yog siv los ua ib qho kev ua haujlwm ntawm microencapsulated tshuaj capsules hauv kev lag luam kws tshuaj los tswj cov tshuaj qeeb.

Kev lag luam thiab kev ua liaj ua teb:

Tshwj xeeb tshaj yog nyob rau hauv kev lag luam roj av, xanthan cov pos hniav yog siv rau viscosity tswj thiab rheological hloov ntawm drilling kua vim nws muaj zog pseudoplasticity thiab zoo heev ntsev tsis kam thiab kub kuj, raws li zoo raws li los txhim kho cov roj rov qab.

Tsis tas li ntawd, xanthan cov pos hniav kuj tseem siv rau hauv cov khoom noj nqaij, ua lub luag haujlwm sib tw, thiab txhim kho saj ntawm jam. Vim nws qhov kub thiab txias tsis kam, siab ntsev thiab siab acid viscosity, xanthan cov pos hniav yog siv nyob rau hauv ntau yam hnyav ib puag ncig thiab zaub mov.

Cov chaw tsim khoom uas peb koom tes nrog muaj kev xa khoom loj ntawm xanthan cov pos hniav, xa khoom sai thiab cov hnub tsim khoom tshiab. Qhov no tuaj yeem pab qee tus neeg muag khoom thiab cov neeg yuav khoom los yuav cov pos hniav xanthan zoo nrog cov hnub tsim khoom tshiab los ntawm peb. Peb yuav tsis muag cov khoom nyob ze rau hnub tas sij hawm rau cov neeg siv khoom zoo li lwm tus, vim tias kev thauj mus los yuav siv sij hawm, yog li peb lub sijhawm xa khoom feem ntau yog teem rau hauv 10-15 hnub, thiab kev txiav txim qis dua 10 tons yuav raug xa tawm hauv 10 hnub.

Cov khoom no yog dab tsi?

Xanthan gum yog ib hom microbial polysaccharide tsim los ntawm Xanthomonas canola. Cov qauv ntawm xanthan cov pos hniav yog nyob ntawm cov pob txha cellulose ntawm β -(1-4) txuas cov piam thaj, nrog rau trisugar sab ntawm mannose-glucuronate-mannose txuas rau txhua lwm cov piam thaj hauv cov pob txha. Qee lub davhlau ya nyob twg mannose units yog acetonated thiab qee qhov hauv mannose units yog acetylated. Vim nws cov khoom tshwj xeeb rheological thiab gel, nws tau dav siv los ua khoom noj khoom haus, thickener thiab stabilizer, thiab tau pom cov ntawv thov hauv cov khoom noj thiab roj av.

Daim ntawv thov

Nws yog tsuas yog siv los ua thickening agent, stabilizer, ncua kev kawm tus neeg sawv cev thiab ua npuas ncauj enhancer rau ntau yam tshuaj pleev ib ce xws li qab zib, tshuaj pleev ib ce thiab tshuaj txhuam hniav los txhim kho cov saj ntawm cov tshuaj txhuam hniav. Tshwj xeeb, nws yog qhov zoo los txhim kho nws qhov kub thiab txias stability nyob rau hauv ib tug dav pH ntau yam.
