The aim of this work was to investigate shrinkage of pumpkin and apple cubes during convective drying. Computer image analysis was used to follow changes of shape and dimensions of the material during drying. Pumpkin shrinks much more than apple and the cross-sectional area of cubes decreased by 73% and 59%, respectively. At the same time decrease of perimeter did not follow the decrease of cross-sectional area. It indicates extensive folding and creasing of the surface of the cubes undergoing drying. At the final stages of drying shrinkage cavities were formed in pumpkin cubes. In apple cubes there were no cavities observed, however dark central areas were seen.
