Internal Porosity Of Corn Extrudate Air Cell Wall, Samuel H. Cohen, Charles A. Voyle
Food Structure
Transmission electron microscopy was used to observe structures within the air cell wall of a corn-based extrudate. Modified fixation and embedding techniques were employed to obtain optimum thin sections. Photomicrographs from these sections showed minute air cells measuring approximately 5 um or less. The size of air cells might impose a limiting factor on the infusion of particulate materials throughout the extrudate matrix.
