Xanthan ntawm cov pos hniav
Xanthan ntawm cov pos hniav yog polysaccharide siv los ua cov zaub mov ntxiv thiab rheology kho tshuab (Davidson Ch. 24). Nws yog tsim los ntawm tus txheej txheem koom nrog fermentation ntawm cov piam thaj lossis sucrose los ntawm Xanthomonas Campesris tus kab mob.
Hauv cov zaub mov, xanthan ntawm cov pos hniav feem ntau pom nyob rau hauv kev noj tshuaj nyias thiab kua qaub. Nws pab tswj cov roj colloidal thiab cov khoom sib txawv tiv thaiv creaming los ntawm kev ua yeeb yam raws li emulsifier. Kuj siv hauv cov zaub mov khov thiab dej haus, xanthan ntawm cov pos hniav tsim cov kev ntxhib los mos ntxiag hauv ntau cov dej khov. Tshuaj txhuam hniav txhuam feem ntau muaj xanthan ntawm cov pos hniav, qhov twg nws ua rau cov phau ntawv los khaws cov khoom hnav. Xanthan ntawm cov pos hniav tseem siv tau nyob rau hauv gluten-dawb ci. Txij li thaum lub gluten pom nyob rau hauv cov qoob yuav tsum tau txiav, xanthan ntawm cov pos hniav yog siv los muab lub khob noom cookie lossis roj "uas yuav ua tiav nrog lub gluten. Xanthan ntawm cov pos hniav kuj tseem pab ua kom tuab hloov lub caij ua lag luam ua los ntawm cov qe qe los hloov cov rog thiab emulsifiers pom hauv yolks. Nws tseem yog ib txoj kev nyiam dua ntawm cov kua uas ua kom zoo rau cov neeg uas tau nqos tsis sib haum, vim nws tsis hloov cov xim lossis cov khoom noj lossis dej haus.h
Nyob rau hauv cov roj kev lag luam, xanthan ntawm cov pos hniav yog siv nyob rau hauv ntau ntau, feem ntau yog ua kom tuab drilling kua. Cov kua dej no pab nqa cov khib nyiab txiav los ntawm cov kab laum qeeb rov qab mus rau saum npoo. Xanthan ntawm cov pos hniav muab cov "qis kawg" rhelology. Thaum cov hlab ntsha nres, cov khib nyiab tseem nyob rau hauv cov kua drilling. Qhov thaiv kev siv ntawm kab rov tav thiab qhov kev thov rau kev tswj kom zoo ntawm cov khib nyiab dr drows tau coj mus rau kev siv Xanthan hniav. Xanthan ntawm cov pos hniav kuj tseem tau ntxiv rau pob zeb ntim hauv dej hauv qab, txhawm rau kom nws viscosity thiab tiv thaiv kev ntxuav.
