Xanthan Gum Biopolymer

Xanthan cov pos hniav yog soluble nyob rau hauv dej, tab sis yuav tsum tau dispersion kom zoo los tiv thaiv clumping los yog clumping uas yuav cuam tshuam rau kev ntxhib los mos thiab sib xws ntawm cov khoom kawg. Yog li ntawd, nyob ntawm daim ntawv thov thiab xav tau cov khoom kawg, nws yog ib qho tseem ceeb uas yuav tau siv qhov tseeb concentration ntawm xanthan cov pos hniav. Feem ntau, qhov ntau ntawm 0.1% mus rau 2% yog txaus rau feem ntau cov zaub mov thiab cov ntawv thov tsis yog khoom noj. Txawm li cas los xij, nws yog qhov zoo tshaj plaws los pib nrog qhov qis dua thiab nce qhov concentration raws li xav tau thaum saib xyuas qhov loj ntawm dispersion.

Xanthan gum ua tau zoo tshaj plaws ntawm pH ntau ntawm 1 txog 13, ua rau nws muaj ntau yam biopolymer uas ua haujlwm hauv acidic, nruab nrab, thiab alkaline ib puag ncig. Txawm li cas los xij, huab cua pH yuav cuam tshuam rau nws txoj kev ruaj ntseg thiab thickening zog. Ib yam li ntawd, qhov kub thiab txias tuaj yeem cuam tshuam cov khoom ntawm xanthan cov pos hniav. Nws tuaj yeem tiv taus qhov kub txog li 80 degree, tab sis lub sij hawm raug rau qhov kub thiab txias yuav ua rau poob ntawm viscosity.

Xanthan cov pos hniav tuaj yeem sib tov zoo nrog feem ntau cov khoom xyaw ntuj lossis hluavtaws. Txawm li cas los xij, nws txoj kev sib raug zoo nrog lwm cov khoom tuaj yeem sib txawv nyob ntawm ntau yam xws li concentration, pH, kub, thiab lwm yam. Yog li ntawd, nws yog ib qho tseem ceeb rau kev sim xanthan cov pos hniav kom sib haum nrog lwm cov khoom xyaw ua ntej siv nws hauv cov khoom kawg.

Xanthan cov pos hniav yog ib qho zoo, lub teeb hmoov uas tuaj yeem ya tau yooj yim thiab tsim cov plua plav. Yog li ntawd, nws raug nquahu kom ua haujlwm nrog kev saib xyuas thiab hnav cov iav tiv thaiv xws li lub qhov ncauj qhov ntswg lossis hnab looj tes. Ib yam li ntawd, nws yog ib qho tseem ceeb uas yuav tsum khaws xanthan cov pos hniav nyob rau hauv qhov chaw txias, qhuav, deb ntawm noo noo thiab ncaj qha tshav ntuj. Qhov no yuav pab tiv thaiv cov hmoov los ntawm clumping los yog clumping.
