Psyllium fiber is widely used in nutrition and digestive health applications due to its functional and physiological benefits, including support for digestive regularity, cholesterol management, and glycemic control. However, when psyllium powder is mixed with water, it rapidly hydrates and forms a viscous gel . This rapid thickening can negatively impact drinkability, limiting consumer acceptance and the range of possible formats for fiber-based beverages.
From a scientific perspective, viscosity and gel development in psyllium systems is driven by hydration kinetics, molecular interactions, and network formation in aqueous environments. While these properties are desirable for physiological function, they present challenges for applications that require a smooth, easy-to-drink liquid over a longer time window after preparation.
Advances in material science, food science, and polymer chemistry may offer new approaches to temporarily delay and/or modulate gel formation (e.g., reduce gel structure/strength or viscosity buildup) without eliminating the underlying functional benefits of psyllium fiber.
We are looking for scientific approaches or technologies that can (a) delay the onset of gel formation and/or (b) reduce gel structure/strength (i.e., lower viscosity or weaker network development) when psyllium fiber powder is mixed with water, while maintaining its core functional properties. Solutions may involve physical, chemical, biological, or formulation-based strategies that modulate hydration, viscosity development, or network formation during the initial mixing and consumption duration, with the goal of maintaining a low-viscosity, drinkable state for a longer period after preparation.
