Abstract

The objective of this study was to examine the effects of rice (R) and brown rice (BR) flour on the quality characteristics of morning bread. The quality characteristics of morning bread were determined by measuring the pH of the dough, dough raising power, moisture content, baking loss rate, specific volume, height, color value, texture analysis and sensory evaluations. The pH of the bread dough was highest on R1:BR2 and R0:BR3. The dough raising power and moisture content steadily and significantly decreased as the amount of added brown rice flour increased. The baking loss rate was highest on R3:BR0. The specific volume and height of morning bread were highest on R3:BR0 and R2:BR1. In color value, the L value decreased significantly as the amount of added brown rice flour increased, while a value and b value increased. The hardness, gumminess and chewiness of morning bread increased with an increase in brown rice flour. In consumer acceptability, R3:BR0, R2:BR1 and R1:BR2 showed the highest scores in all parameters. Characteristic intensity rating of roasted taste was lowest on R3:BR0. These results indicate that R2:BR1 showed similar quality characteristics as compared to morning bread without brown rice flour, with the optimal results appreciated with a 2:1 ratio of rice flour to brown rice flour.
