Chaw Tsim Khoom Zoo Tus Nqi Xanthan Gum Qib Muaj CAS: 11138-66-2 Duab Tshwj Xeeb

piav qhia luv luv:

Xanthan gum, tseem hu ua Hanseonggum, yog ib hom microbial exopolysaccharide uas tsim los ntawm Xanthomnas campestris nrog carbohydrate ua cov khoom siv tseem ceeb (xws li hmoov txhuv nplej siab) los ntawm kev fermentation engineering. Nws muaj rheology tshwj xeeb, solubility dej zoo, ruaj khov rau cua sov thiab acid puag, thiab muaj kev sib raug zoo nrog ntau yam ntsev. Ua tus neeg sawv cev thickening, suspension agent, emulsifier, stabilizer, tuaj yeem siv dav hauv zaub mov, roj av, tshuaj thiab lwm yam ntau dua 20 kev lag luam, tam sim no yog lub ntiaj teb qhov loj tshaj plaws ntawm kev tsim khoom thiab siv dav heev microbial polysaccharide.

Xanthan gum yog hmoov daj dawb dawb uas txav tau, me ntsis tsw ntxhiab. Yaj tau hauv dej txias thiab dej kub, cov kua nruab nrab, tiv taus khov thiab yaj, tsis yaj hauv ethanol. Dej dispersion, emulsification rau hauv cov hydrophilic viscous colloid ruaj khov.

Cov yam ntxwv

1) Nrog rau qhov nce ntawm qhov nrawm shear, cov khoom rheological ib txwm muaj, vim yog kev puas tsuaj ntawm lub network colloidal, txo qhov viscosity thiab dilute cov kua nplaum, tab sis thaum lub zog shear ploj mus, qhov viscosity tuaj yeem rov qab tau, yog li nws muaj cov khoom siv twj thiab ua tiav zoo. Los ntawm kev siv cov khoom no, xanthan gum raug ntxiv rau cov kua uas xav tau kom tuab. Cov kua tsis yog tsuas yog yooj yim ntws hauv cov txheej txheem thauj mus los, tab sis kuj tuaj yeem rov qab mus rau qhov viscosity xav tau tom qab nws tseem nyob. Yog li ntawd, nws yog siv dav hauv kev lag luam dej haus.

2) Cov kua nplaum uas muaj viscosity siab muaj 2% ~ 3% xanthan gum ntawm qhov concentration qis, nrog viscosity txog li 3 ~ 7Pa.s. Nws cov viscosity siab ua rau nws muaj kev siv dav dav, tab sis tib lub sijhawm, nws coj teeb meem rau kev ua tiav tom qab ntawm kev tsim khoom. 0.1% NaCl thiab lwm yam ntsev univalent thiab Ca, Mg thiab lwm yam ntsev bivalent tuaj yeem txo qhov viscosity ntawm cov kua nplaum qis dua 0.3% me ntsis, tab sis tuaj yeem ua rau cov kua nplaum viscosity nce ntxiv nrog qhov concentration siab dua.

3) Qhov viscosity ntawm cov xanthan gum uas tiv taus cua sov yuav luag tsis muaj kev hloov pauv hauv qhov kub thiab txias dav (- 98 ~ 90 ℃). Qhov viscosity ntawm cov tshuaj tsis hloov pauv ntau txawm tias nws khaws cia ntawm 130 ℃ rau 30 feeb thiab tom qab ntawd txias. Tom qab ntau lub voj voog khov-thaw, qhov viscosity ntawm cov kua nplaum tsis hloov pauv. Thaum muaj ntsev, cov tshuaj muaj kev ruaj khov thermal zoo. Yog tias ntxiv me ntsis electrolyte, xws li 0.5% NaCl ntawm qhov kub siab, qhov viscosity ntawm cov kua nplaum tuaj yeem ruaj khov.

4) Qhov viscosity ntawm cov kua qaub thiab alkaline xanthan gum aqueous solution yuav luag tsis muaj pH. Cov khoom tshwj xeeb no tsis muaj los ntawm lwm cov thickeners xws li carboxymethyl cellulose (CMC). Yog tias qhov concentration ntawm inorganic acid hauv cov kua nplaum siab dhau, cov kua nplaum yuav tsis ruaj khov; Thaum kub siab, qhov hydrolysis ntawm polysaccharide los ntawm acid yuav tshwm sim, uas yuav ua rau qhov viscosity ntawm cov kua nplaum txo qis. Yog tias cov ntsiab lus ntawm NaOH ntau dua 12%, cov xanthan gum yuav gelled lossis txawm tias precipitated. Yog tias qhov concentration ntawm sodium carbonate ntau dua 5%, cov xanthan gum kuj yuav gelled.

5) Cov pob txha xanthan gum uas tiv thaiv enzymatic muaj peev xwm tshwj xeeb uas tsis pub hydrolyzed los ntawm cov enzymes vim yog qhov cuam tshuam ntawm cov saw hlau sab.

6) Cov xanthan gum uas sib xws tuaj yeem sib xyaw nrog cov khoom noj uas siv ntau tshaj plaws, tshwj xeeb tshaj yog nrog alginate, hmoov txhuv nplej siab, carrageenan thiab carrageenan. Qhov viscosity ntawm cov tshuaj nce ntxiv hauv daim ntawv ntawm superposition. Nws qhia tau tias muaj kev sib raug zoo hauv cov kua dej nrog ntau yam ntsev. Txawm li cas los xij, cov hlau ions siab thiab pH siab yuav ua rau lawv tsis ruaj khov. Kev ntxiv cov neeg sawv cev complexing tuaj yeem tiv thaiv qhov tshwm sim ntawm kev tsis sib xws.

7) Cov roj xanthan yooj yim yaj hauv dej thiab tsis yaj hauv cov kuab tshuaj polar xws li cawv thiab ketone. Hauv ntau qhov kub thiab txias, pH thiab ntsev concentration, nws yooj yim yaj hauv dej, thiab nws cov kua dej tuaj yeem npaj tau ntawm chav tsev kub. Thaum do, yuav tsum txo qhov sib tov cua. Yog tias xanthan gum sib xyaw nrog qee cov khoom qhuav ua ntej, xws li ntsev, qab zib, MSG, thiab lwm yam, tom qab ntawd ntub nrog me ntsis dej, thiab thaum kawg sib xyaw nrog dej, cov kua nplaum uas tau npaj tseg muaj kev ua tau zoo dua. Nws tuaj yeem yaj hauv ntau cov kua qaub organic, thiab nws cov kev ua tau zoo ruaj khov.

8) Lub peev xwm ntawm 1% dispersible xanthan gum kua yog 5N / m2, uas yog ib qho zoo heev suspending agent thiab emulsion stabilizer hauv cov khoom noj khoom haus additives.

9） Cov roj xanthan uas khaws dej tau zoo muaj cov dej zoo thiab ua kom cov zaub mov tshiab.

Cov ntawv thov ntawm Xanthan Gum Industrial qib

1) Hauv kev lag luam roj av, 0.5% xanthan gum aqueous solution tuaj yeem tswj tau qhov viscosity ntawm cov dej-raws li drilling fluid thiab tswj nws cov rheological zog, yog li ntawd qhov viscosity ntawm high-speed rotating bits yog qis heev, uas txuag tau ntau lub zog siv, thaum nyob rau hauv qhov chaw drilling static, nws tuaj yeem tswj tau qhov viscosity siab, uas ua lub luag haujlwm hauv kev tiv thaiv kev tawg ntawm lub qhov dej thiab pab txhawb kev tshem tawm cov pob zeb tawg sab nraum lub qhov dej.

2） Hauv kev lag luam khoom noj, nws zoo dua li cov khoom noj khoom haus tam sim no xws li gelatin, CMC, seaweed gum thiab pectin. Ntxiv 0.2% ~ 1% rau cov kua txiv ua rau cov kua txiv muaj kev nplaum zoo, saj zoo, thiab tswj kev nkag mus thiab ntws; Ua ib qho khoom ntxiv rau qhob cij, tuaj yeem ua rau qhob cij ruaj khov, du, txuag lub sijhawm thiab txo tus nqi; Kev siv 0.25% hauv kev sau qhob cij, kev sau sandwich zaub mov thiab txheej qab zib tuaj yeem ua rau kom saj thiab tsw qab, ua rau cov khoom du, ntev lub txee lub neej, thiab txhim kho kev ruaj khov ntawm cov khoom rau cua sov thiab khov; Hauv cov khoom noj mis nyuj, ntxiv 0.1% ～ 0.25% rau ice cream tuaj yeem ua lub luag haujlwm zoo heev; Nws muab kev tswj hwm viscosity zoo hauv cov zaub mov kaus poom thiab tuaj yeem hloov ib feem ntawm cov hmoov txhuv nplej siab. Ib feem ntawm xanthan gum tuaj yeem hloov 3-5 feem ntawm cov hmoov txhuv nplej siab. Tib lub sijhawm, xanthan gum kuj tau siv dav hauv khoom qab zib, condiments, khoom noj khov thiab khoom noj kua.
