Chaw tsim tshuaj paus Zoo Nqe Xanthan Gum Industrial qib CAS: 11138-66-2 Featured duab

piav qhia luv luv:

Xanthan gum, tseem hu ua Hanseonggum, yog ib hom microbial exopolysaccharide uas yog tsim los ntawm Xanthomnas campestris nrog carbohydrate ua raw khoom (xws li pob kws starch) los ntawm fermentation engineering.Nws muaj qhov tshwj xeeb rheology, dej solubility zoo, ruaj khov rau cua sov thiab acid puag, thiab muaj kev sib raug zoo nrog ntau yam ntsev.Raws li ib tug thickening neeg sawv cev, ncua kev kawm ntawv tus neeg saib xyuas, emulsifier, stabilizer, yuav lug siv nyob rau hauv cov zaub mov, roj av, tshuaj thiab lwm yam tshaj li 20 industries, yog tam sim no lub ntiaj teb no loj tshaj plaws ntau lawm teev thiab heev lug siv microbial polysaccharide.

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.Dej dispersion, emulsification rau hauv ib qho ruaj khov hydrophilic viscous colloid.

Yam ntxwv

1) Nrog rau qhov nce ntawm qhov shear npaum li cas, cov yam ntxwv rheological, vim kev puas tsuaj ntawm cov colloidal network, txo cov viscosity thiab dilute cov kua nplaum, tab sis thaum lub shear quab yuam ploj, lub viscosity yuav rov qab los, yog li nws muaj zoo twj. thiab ua cov khoom.Los ntawm kev siv cov cuab yeej no, xanthan cov pos hniav ntxiv rau cov kua uas yuav tsum tau ua kom tuab.Cov kua dej tsis yog tsuas yog yooj yim los khiav hauv txoj kev thauj mus los, tab sis kuj tuaj yeem rov qab mus rau qhov xav tau viscosity tom qab nws tseem.Yog li ntawd, nws yog dav siv hauv kev lag luam dej haus.

2) High viscosity kua uas muaj 2% ~ 3% xanthan cov pos hniav ntawm qhov tsis tshua muaj siab, nrog viscosity mus txog 3 ~ 7Pa.s.Nws cov viscosity siab ua rau nws muaj kev thov dav dav, tab sis tib lub sijhawm, nws ua rau muaj teeb meem rau kev ua tiav tom qab kev tsim khoom.0.1% NaCl thiab lwm cov ntsev tsis zoo thiab Ca, Mg thiab lwm cov ntsev bivalent tuaj yeem txo qis me ntsis ntawm cov kua nplaum qis qis dua 0.3%, tab sis tuaj yeem ua kom cov kua nplaum nplaum ntau dua.

3) Lub viscosity ntawm tshav kub-resistant xanthan cov pos hniav yuav luag tsis muaj kev hloov nyob rau hauv ib tug kuj dav kub ntau yam (- 98 ~ 90 ℃).Lub viscosity ntawm cov tshuaj tsis hloov pauv loj txawm tias nws tau khaws cia ntawm 130 ℃ rau 30 min thiab tom qab ntawd txias.Tom qab ob peb lub voj voog khov-thaw, viscosity ntawm cov kua nplaum tsis hloov.Nyob rau hauv lub xub ntiag ntawm ntsev, cov tshuaj muaj zoo thermal stability.Yog tias ib qho me me ntawm electrolyte, xws li 0.5% NaCl, ntxiv rau ntawm qhov kub thiab txias, viscosity ntawm cov kua nplaum tuaj yeem ruaj khov.

4) Lub viscosity ntawm acid resistant thiab alkaline xanthan gum aqueous kua yog yuav luag ywj siab ntawm pH.Cov cuab yeej tshwj xeeb no tsis muaj los ntawm lwm cov thickeners xws li carboxymethyl cellulose (CMC).Yog tias qhov concentration ntawm inorganic acid nyob rau hauv cov kua nplaum yog siab dhau lawm, cov kua nplaum yuav tsis ruaj khov;Nyob rau hauv qhov kub thiab txias, lub hydrolysis ntawm polysaccharide los ntawm acid yuav tshwm sim, uas yuav ua rau lub viscosity ntawm cov kua nplaum yuav txo.Yog hais tias cov ntsiab lus ntawm NaOH ntau dua 12%, cov pos hniav xanthan yuav gelled los yog txawm precipitated.Yog tias qhov concentration ntawm sodium carbonate ntau dua 5%, cov pos hniav xanthan kuj yuav raug gelled.

5) Cov tshuaj tiv thaiv enzymatic xanthan cov pos hniav pob txha pob txha muaj lub peev xwm tshwj xeeb kom tsis txhob hydrolyzed los ntawm enzymes vim muaj kev tiv thaiv ntawm cov saw hlau sab.

6) Tau tshaj xanthan cov pos hniav tuaj yeem tov nrog cov khoom noj khoom haus uas siv ntau tshaj plaws, tshwj xeeb tshaj yog nrog alginate, starch, carrageenan thiab carrageenan.Lub viscosity ntawm cov tshuaj nce nyob rau hauv daim ntawv ntawm superposition.Nws qhia tau hais tias zoo compatibility nyob rau hauv aqueous daws nrog ntau yam ntsev.Txawm li cas los xij, high valence hlau ions thiab pH siab yuav ua rau lawv tsis ruaj khov.Ntxiv tus neeg sawv cev complexing tuaj yeem tiv thaiv qhov tshwm sim ntawm incompatibility.

7) Soluble xanthan cov pos hniav yog yooj yim soluble nyob rau hauv dej thiab insoluble nyob rau hauv polar solvents xws li cawv thiab ketone.Nyob rau hauv ntau qhov kub thiab txias, pH thiab ntsev concentration, nws yooj yim rau yaj hauv dej, thiab nws cov kua dej tuaj yeem npaj tau ntawm chav tsev kub.Thaum stirring, huab cua sib tov yuav tsum tau txo kom tsawg.Yog tias xanthan cov pos hniav sib xyaw nrog qee cov tshuaj qhuav ua ntej, xws li ntsev, suab thaj, MSG, thiab lwm yam, ces moistened nrog dej me me, thiab thaum kawg tov nrog dej, cov kua nplaum npaj tau zoo dua.Nws tuaj yeem yaj hauv ntau cov organic acid daws, thiab nws qhov kev ua tau zoo yog ruaj khov.

8) Lub peev xwm ntawm 1% dispersible xanthan cov pos hniav yog 5N / m2, uas yog ib qho zoo heev tshem tawm tus neeg sawv cev thiab emulsion stabilizer nyob rau hauv cov khoom noj additives.

9) Cov dej khaws cia xanthan cov pos hniav muaj cov dej zoo khaws cia thiab cov khoom noj tshiab.
