To enhance its value, we subjected soybean residue to superfine grinding and measured the resulting physiochemical properties and antioxidant activities. We prepared powders with particle sizes of 115.35, 77.93, 39.38, 25.01, and 20.44 μm.

 · Coarse (unit:micro meter) Fine (unit:micro meter) dυ-50 value = particle diameter at 50% point of cumulative height dυ-94 value = particle diameter at 94% point of cumulative height Grain size is closely related to the roughness of a finished surface. Generally coarser wheel results in a greater efficiency and a less smooth finished surface.
