黄原胶的高黏度导致其在溶液中固含量较低，难以满足工业应用需求，因此开发高固含量的黄原胶溶液是一项具有挑战性的任务。文章提出一种简单高效的制备策略：将黄原胶颗粒分散于非极性液体以提升其固含量，并进一步评价该悬浮液的稳定性及影响因素。黄原胶悬浮液主要由黄原胶颗粒、聚合物黏合剂(羧丙基甲基纤维素)、表面活性剂(月桂醇聚氧乙烯醚磺基琥珀酸酯二钠或月桂基磺化琥珀酸单酯二钠)和植物油组成。通过改变悬浮液中表面活性剂成分和环境温度，文章揭示了各组分间的相互作用，并评估了表面活性剂的分子尺寸与温度对悬浮液稳定性的影响。研究发现，较大分子尺寸的表面活性剂有助于提升悬浮液的稳定性；而升高温度，表面活性剂对悬浮液稳定性的影响无显著差异。
Abstract：The high viscosity of xanthan gum leads to a low solid content in its solution, which is difficult to meet the requirements of industrial applications. Therefore, developing a xanthan gum solution with a high solid content is a challenging task. This article proposes a simple and efficient preparation strategy: dispersing xanthan gum particles in a non-polar liquid to increase its solid content, and further evaluating the stability of the suspension and the influencing factors. The xanthan gum suspension mainly consists of xanthan gum particles, a polymer binder(carboxymethyl cellulose propyl ether), surfactants(disodium lauryl ether sulfosuccinate and disodium lauryl sulfosuccinate), and vegetable oil. By changing the surfactant composition in the suspension and the environmental temperature, the article reveals the interactions among the components and assesses the effects of surfactant molecular size and temperature on the stability of the suspension. The study found that surfactants with larger molecular sizes help improve the stability of the suspension; however, when the temperature is increased, there is no significant difference in the effect of surfactants on the stability of the suspension.
