ABSTRACT The cell size distributions of various experimental puffed corn extrudates were determined by image analysis, applied to longitudinal and transversal cross sections. Individual cell cross‐sectional area was used as the size measure. All the cell size distributions, regardless of specimen orientation, composition and extrusion conditions, were described mathematically by both the log‐normal and Rosin‐Rammler distribution functions. The distributions mean size, degree of skew‐ness or the corresponding distribution functions constants, were characteristic of the extrudate type and its particular cellular structure.
