Sodium carboxymethyl cellulose (CMC) thiab xanthan cov pos hniav yog ob qho tib si feem ntau siv los ua cov thickening agents thiab stabilizers nyob rau hauv ntau yam kev lag luam. Txawm li cas los xij, muaj qee qhov sib txawv ntawm ob:

1. Tshuaj muaj pes tsawg leeg: CMC yog cellulose derivative, whereas xanthan gum yog ib tug polysaccharide muab los ntawm fermentation ntawm ib tug kab mob hu ua Xanthomonas campestris.
2. Solubility: CMC yog soluble nyob rau hauv dej txias, whereas xanthan gum yog soluble nyob rau hauv dej kub thiab txias.
3. Viscosity: CMC muaj viscosity siab dua xanthan cov pos hniav, txhais tau tias nws thickens cov kua ntau zoo.
4. Synergy: CMC tuaj yeem ua haujlwm sib koom ua ke nrog lwm cov thickeners, thaum xanthan cov pos hniav zoo li ua haujlwm zoo ib leeg.
5. Cov khoom muaj txiaj ntsig zoo: Xanthan cov pos hniav muaj lub qhov ncauj slimy los yog slippery qhov ncauj, qhov CMC muaj qhov zoo nkauj dua thiab creamy.

Zuag qhia tag nrho, ob qho tib si CMC thiab xanthan cov pos hniav yog cov thickeners zoo thiab stabilizers, tab sis lawv muaj cov khoom sib txawv thiab siv ntau yam kev siv. CMC feem ntau siv rau hauv cov khoom noj, tshuaj, thiab tshuaj pleev ib ce, thaum xanthan cov pos hniav feem ntau siv rau hauv cov khoom noj thiab cov khoom tu tus kheej.
