Xanthan cov pos hniav, tseem hu ua Hansen cov pos hniav, yog microbial extracellular polysaccharide uas tsim los ntawm cov txheej txheem fermentation ntawm cov kab mob Xanthomonas campestris siv cov carbohydrates ua cov khoom siv tseem ceeb (xws li pob kws hmoov txhuv nplej siab).Nws muaj cov khoom tshwj xeeb rheological, dej solubility zoo, ruaj khov rau cov cua sov thiab cov kua qaub thiab cov hauv paus, thiab kev sib raug zoo nrog ntau cov ntsev, thiab yog siv dav hauv cov thickener, suspending agent, emulsifier thiab stabilizer nyob rau hauv ntau tshaj 20 industries xws li zaub mov, petroleum thiab pharmaceuticals.
Kev lag luam khoom noj khoom haus: feem ntau siv rau hauv cov khoom ci, khoom qab zib, kua txiv hmab txiv ntoo, khoom noj khoom haus thiab cov khoom noj khov, thiab lwm yam, tuaj yeem ua rau cov khoom noj muaj kuab lom, txhim kho saj thiab ua kom cov khoom noj khoom haus ntau dua.
Kev lag luam kws tshuaj: xanthan cov pos hniav yog cov khoom siv tshuaj tseem ceeb, nws tuaj yeem tsis tsuas yog siv los ua cov khoom siv raw rau cov tshuaj ntsiav, tib neeg cov ntaub so ntswg tshwj xeeb kho cov ntaub ntawv, tab sis kuj siv los tsim cov tshuaj hauv qhov ncauj, txhaj tshuaj, qhov muag tee thiab lwm yam tshuaj.
Kev lag luam khoom noj khoom haus: tsis txhob muaj cua sov ntau li ntau tau, nyiam dua ntawm qhov kub ntawm 40 ° C - 60 ° C.Cov koob tshuaj yog nruab nrab ntawm 0.2% thiab 2%.Feem ntau, cov khoom noj thicker thiab hnyav dua qhov ntau dua cov pos hniav xanthan ntxiv.
Kev lag luam kws tshuaj: ntau npaum li cas sib txawv raws li lub sijhawm siv.Feem ntau xanthan cov pos hniav tuaj yeem tov ncaj qha nrog cov tshuaj lossis raug tshem tawm hauv ib qho kev daws teeb meem.
