Physicochemical and sensory properties of sponge cakes using 2 kinds of domestic wheat flour(white flour, whole wheat flour) and imported cake flour were investigated. In the proximate analysis, white flour had higher contents of water and protein compared with those of imported flour. Whole wheat flour had the highest contents of protein, lipid and ash. Regarding the batter, imported flour sample showed lower specific gravity and higher viscosity than those of domestic flour sample, implying that there was more air incorporation and higher batter stability. As a result, imported flour batter produced larger cake compared to that of domestic flour batter. But indexes of symmetry and uniformity showed no significant difference among the samples. In textural analysis using rheometer, cakes with imported flour were softer compared with that with domestic flour. In gumminess and brittleness, cakes with domestic white flour showed the highest value while that with the imported flour showed the lowest value. For the color measurements of cake crumb, no significant difference in DE was found among the samples. Regarding the cross-sections of the cake observed using SEM, imported flour produced cake with smaller and more even air cells compared to that with the domestic flour cake. In sensory evaluation, cakes with the domestic white flour showed the highest moistness value. But there was no significant difference in springiness, firmness, adhesiveness and ease of swallow among the samples. In conclusion, cakes with domestic white flour and whole wheat flour were as good as that with imported cake flour for the sponge cake preparation.
