Gas cell distribution (sudachi) of baked cereal products was determined with computer image analysis of a print with China ink (print method) of a cross section of the product and a photograph (photo method) of the cross section stained with China ink. For the"sudachi" of bread, a positive correlation was obtained between the number of gas cell counted manually and the number measured with Image Analyzer (print method). A positive correlation was also obtained between the number of gas cell determined with thephoto method and that determined with the print method. By the photo method, both the specific volume and the ratio of gas cell area to the whole area of the cross section correlated negatively with the number of gas cell. A positive correlation was found betweenthe specific volume and the ratio of gas cell area to the whole area of the cross section. For butter sponge cake, the number of gas cell correlated negatively with the specific volume. Positive correlations were obtained between the specific volume and the ratio of gas cellarea to the whole area of the cross section, and between the number of gas cell and Heywood diameter of gas cell. From these results, it is concluded that computerized image analysis is very available for the investigation of "sudachi" of baked cereal products because of its convenience of measuring procedure.
