Xanthan Gum
Xanthan gum yog ib qho polysaccharide siv los ua khoom noj khoom haus thiab kev hloov kho rheology (Davidson ch. 24).Nws yog tsim los ntawm cov txheej txheem uas muaj fermentation ntawm qabzib los yog sucrose los ntawm cov kab mob Xanthomonas campestris.
Hauv cov khoom noj, xanthan cov pos hniav feem ntau pom muaj nyob rau hauv cov zaub nyoos thiab cov kua ntses.Nws pab kom ruaj khov ntawm cov roj colloidal thiab cov khoom siv tiv thaiv cream los ntawm kev ua tus emulsifier.Kuj tseem siv rau hauv cov khoom noj khov thiab dej haus, xanthan cov pos hniav tsim cov kev ntxhib los mos zoo nkauj hauv ntau cov ice cream.Cov tshuaj txhuam hniav feem ntau muaj xanthan cov pos hniav, qhov chaw uas nws ua haujlwm los ua kom cov khoom sib xws.Xanthan cov pos hniav kuj siv rau hauv gluten-dawb ci.Txij li thaum gluten pom nyob rau hauv cov nplej yuav tsum tau muab tshem tawm, xanthan cov pos hniav yog siv los muab lub khob noom cookie los yog batter ib "stickiness" uas yuav txwv tsis pub ua tiav nrog gluten.Xanthan cov pos hniav kuj tseem pab ua kom cov qe ua lag luam ua los ntawm cov qe dawb los hloov cov rog thiab cov emulsifiers pom hauv yolks.Nws kuj yog ib txoj kev nyiam ntawm cov kua dej thickening rau cov neeg uas muaj kev nqhis dej, vim nws tsis hloov xim lossis tsw ntawm cov zaub mov lossis dej haus.H
Hauv kev lag luam roj, xanthan cov pos hniav yog siv ntau qhov ntau, feem ntau ua rau cov kua dej ua kom tuab.Cov kua dej no pab nqa cov khib nyiab txiav los ntawm qhov drilling me ntsis rov qab mus rau qhov chaw.Xanthan gum muab qhov zoo "kawg kawg" rheology.Thaum lub voj voog nres, cov khib nyiab tseem raug tshem tawm hauv cov kua dej drilling.Kev siv dav dav ntawm kab rov tav drilling thiab qhov kev thov kom muaj kev tswj xyuas zoo ntawm cov khoom siv drilling tau ua rau nthuav dav siv xanthan cov pos hniav.Xanthan cov pos hniav kuj tau ntxiv rau cov pob zeb hauv qab dej, txhawm rau ua kom nws cov viscosity thiab tiv thaiv kev ntxuav tawm.
