Psyllium Husk Viscosity Reduction via Soluble Compound Mediation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high viscosity of psyllium husk suspensions poses a challenge for consumer acceptance and processing, as it requires large amounts of water and energy for drying, and existing modifications may affect the physiological effects of psyllium husk, with limited evidence from human feeding trials.
Innovation Solution
Incorporating a soluble compound such as a polysaccharide or protein with a molecular weight of 500 Da to 1,000 kDa and a 1% solution viscosity of up to 10 mPa·s into the psyllium husk suspension to decrease viscosity, without replacing the psyllium, thereby improving palatability and processing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If psyllium husk is mixed with water to form a suspension, then the dietary fiber can be consumed and provide health benefits, but the viscosity becomes too high for consumer acceptance and difficult processing
Solution Approach 1:
A soluble compound (polysaccharide or protein) is introduced as an intermediary substance that mediates between the psyllium husk and water. This intermediary binds to the psyllium molecules and prevents excessive water absorption and gel formation, thereby reducing viscosity while allowing the psyllium to maintain its health benefits
Solution Approach 2:
The patent creates a composite material system consisting of psyllium husk, soluble compound, and water. The soluble compound acts as a third component that modifies the interaction between psyllium and water, resulting in a composite suspension with reduced viscosity but preserved functional properties
2Ease of operation
If physical, chemical, or enzymatic modifications are applied to psyllium polysaccharides to decrease viscosity, then the viscosity is reduced, but the physiological effects may be compromised
Solution Approach 1:
The patent separates the viscosity-reduction function from the health benefit function. The soluble compound handles the viscosity reduction task, while the psyllium husk maintains its intact molecular structure and physiological activity. This functional segmentation allows both objectives to be achieved independently
Solution Approach 2:
The soluble compound serves as a mediator that reduces viscosity without directly modifying the psyllium polysaccharide structure. This indirect approach preserves the physiological effects while achieving the desired viscosity reduction
3Ease of manufacture
If solid state enzymatic treatment is used to process psyllium husk, then processing difficulty is reduced, but the treatment cost increases due to enzyme expense
Solution Approach 1:
The patent changes the processing parameter from enzymatic treatment to physical mixing with a soluble compound. This parameter change transforms the process from a costly chemical/biological treatment to a simpler physical process, reducing both processing difficulty and cost
4Ease of operation
If large amounts of water are used to process psyllium husk in wet form, then processing is easier, but energy consumption increases for water removal
Solution Approach 1:
The patent converts the harmful effect of high water absorption (which requires energy-intensive drying) into a beneficial feature. The soluble compound allows water to be present in the suspension without causing excessive absorption, so the water serves to reduce viscosity and improve processing while requiring minimal energy for removal

Function Achieved in This Case
This approach significantly decreases the viscosity of psyllium husk suspensions, allowing for a greater fiber delivery in a single serving while maintaining the health benefits of psyllium husk, and reduces the energy required for processing by minimizing water absorption.
Implementation Method 1

AI summary
Disclosed are methods of decreasing the viscosity of an aqueous suspension of a water insoluble or sparingly soluble dietary fiber (compared to the viscosity of the dietary fiber alone), involving mixing the dietary fiber with water and a soluble compound (e.g., polysaccharide having a molecular weight of about 500 Da to about 1,000 kDa and 1% solution viscosity of up to 10 mPa·s; or protein having a molecular weight of about 10 to about 500 kDa and a 1% solution viscosity of up to 10 mPa·s).
