shows sensory scores for seven attributes of the difference test and five attributes of the preference test. There were significant differences in air cell homogeneity, hardness, chewiness, and softness (p < 0.05), appearance and texture, and overall quality of the preference test also differed significantly. Air cell homogeneity and softness exhibited higher scores in cupcakes prepared from smaller sized rice flour, but hardness and chewiness showed reverse trends. Particle size distributions of rice flours affected the structure of crumbs in appearance, hardness and softness in texture, and overall quality of cupcake. It is suggested that rice flour (HP-120, or HP-160) was appropriate to make cake-type bakery products.
