摘要

An improved process for treating xanthan gums with glyoxal for more complete dispersion in fluid systems comprising the steps of treating milled xanthan particles with a liquefied glyoxal composition. The liquefied glyoxal composition may comprise glyoxal, water and a hydration suppression agent such as salt, alcohol, ketones or mixtures thereof. This invention also relates to the xanthan products prepared by the process of this invention, which provide improved dispersability, hydration and filterability in liquids.
