水膠體對剪切及伸長流變性的影響

// Hydrocolloid Effects on Shear and Extensional Rheology

本研究分析不同增稠水膠體製成之吞嚥困難飲品的剪切與伸長流變特性｜結果顯示HPMC、CMC及MC具高伸長黏度，STA最低，且剪切應力下降與伸長黏度無關聯｜建議優化兩種流變性質，以提升吞嚥安全與效果。

// This study analyzed shear and extensional rheological properties of thickened beverages made with various hydrocolloids for dysphagia management. Fluids were standardized by shear viscosity, showing variable shear thinning behaviors and differing extensional properties, with HPMC, CMC, and MC having high extensional viscosity, and STA the lowest. No correlation was found between shear thinning and extensional viscosity across hydrocolloids. The findings indicate that shear and extensional rheology assess different fluid properties, suggesting both should be optimized to enhance swallowing safety and efficacy.
