Mechanical Properties of Extruded Wheat Flour Foam
This communication reports a research effort on the density related to mechanical behavior of wheat flour foam to optimization. The different extrusion processing condition can result in different densities of the foams. Mechanical properties measured included static compression and dynamic cushioning curves for the wheat starch foams. The relative compressive strength exhibited a power law dependence on relative density, which is following the equation: σc/σs ≈ 0.308 ρ*/ρs1.5. The dynamic cushioning properties of the foam also changed with the density of the foams.
