Xanthan gum; chemical modification; intermolecular interaction; dissolution rate
Xanthan gum is modified with formaldehyde to improve the dissolution rate. The Fr-IR spectra and the X-ray diffraction spectra both show that chemical modification reduces intermolecular interactions and crystallinity. Viscosity measurements show that the chemically modified gum dissolves more rapidly than before. (C) 2002 Published by Elsevier Ltd.
