The microstructures of sesame cake under five applied pressures were measured using stereo light microscope and image-pro software. Fractal dimensions of pore section border and pore size distribution were measured and calculated by the slit island process. Regression method was used to analyse the correlation between the fractal dimension and applied pressure. Results showed that the fractal characteristic of pore structure of sesame cake was obvious, the pore structure and its fractal dimension were significantly affected by applied pressure. There existed good linear correlations between ap...
