Hypothesis
The study investigates the influence of shear on the rheological properties and physical stability of aqueous dispersions of flaxseed fiber.
Conclusion
Higher homogenization rates weaken the gel-like structure of flaxseed fiber dispersions, but the gels remain highly stable.
Supporting Evidence
- Flaxseed fiber dispersions showed shear thinning behavior.
- Physical stability improved with certain homogenization rates.
- All samples exhibited high stability after two months of aging.
Takeaway
This study looks at how mixing flaxseed fiber in water affects its thickness and stability, finding that too much mixing can make it weaker but still stable.
Methodology
The study used small amplitude oscillatory tests, flow curves, and multiple light scattering measurements to analyze the dispersions.
Limitations
The study does not explore the effects of very high shear conditions, such as ultrasonic homogenization or microfluidization.
