  • 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.

  • The purpose of this study was to investigate quality characteristics of roll bread with the addition of Chungkukjang powder(0, 5, 10, 15, 20%). The antioxidative activity of antioxidative substances produced from several bacterial strains isolated from fermented foods were tested by DPPH $(\alpha,\alpha’-diphenyl-\beta-picrylhydrazyl)$ free radical scavenging activity. The most optimal medium condition for the production of antioxidative substance from Bacillus sp. FF-7 was 2% galactose as carbon source and 1% tryptone as nitrogen source. In color values, with increasing Chungkukjang powder content, the "lightness" (p<0.05) decreased in the crumb bread, while the redness(p<0.05) and yellowness(p<0.05) increased. The volume and specific volume of roll bread with 5.0% Chungkukjang powder were the highest(p<0.05). In the rheology measurements for the roll bread, the hardness (p<0.05) decreased with the addition of 5.0% Chungkukjang powder, but then increased with further additions of Chungkukjang up to 10.0%. Highest sensory scores for color, flavor, taste(p<0.05), texture(p<0.05) and overall acceptance(p<0.05) were obtained from roll bread with 5.0% Chungkukjang powder and control. From the results of this study, it was assumed that the development of food products using Chungkukjang is prospective in response to health-oriented consumers.

  • This study was carried out to investigate the quality characteristics and antioxidant activities of bread containing mistletoe (Viscum album var.) powder (at ratios of 0, 3, 5, 7, and 10% of total flour quantity). As mistletoe powder (MP) content increased, the pH levels of dough and bread and lightness decreased, whereas total titratable acidity increased. The fermentation power of the dough expansion by fermentation decreased with an increase in MP content added. Although bread weight decreased, there were no significant differences in baking loss as MP content increased. Volume and specific volume significantly decreased as MP content increased. Moisture content was highest at a substitution level of 10% and increased with increasing MP content. Lightness of crumbs significantly decreased with increasing MP content, whereas redness and yellowness showed the reverse effect. As MP content increased, changes in hardness, gumminess, and brittleness were all significant. In the sensory evaluation, color, flavor, softness, and overall acceptability were highest at MP 3% and were lowest at MP 10%. Total polyphenol contents and DPPH radical scavenging activity of bread significantly increased with increasing MP content. In conclusion, addition of MP 3% showed the best performance in terms of the nutritional and functional aspects of the bread.

  • This study was to investigate the quality characteristics of white pan bread with added Nurungji, scorched rice. Nurungji powder at the level of 5% (N5), 10% (N10), 15% (N15), 20% (N20) was mixed with flour to make the bread. The overall effects of nurungji powder in pan bread were examined by investigating fermentation rates, volume change, farinograph and TPA analysis, color and preference evaluation. A control showed the highest fermentation rate by 60 min, but there was no significant difference between all samples. Farinograph analysis showed that the water absorption rate was the lowest in control and increased with the addition of nurungji powder. In contrast, in dough development time, control was the shortest and the N20 was the longest. Dough stability showed the best with control, N20 showed the lowest value, and Dough weakness increased significantly as the amount of rice powder was increased. According to TPA analysis it had shown significant differences in hardness and chewiness in the bread with Nurungi. Volume and specific volume tended to decrease as the amount of rice powder added increased. Sensory evaluation showed that the texture of bread had the highest with control, and the overall preference such as color, taste, and flavor showed the best with N15.

  • The purpose of this study was to evaluate the quality characteristics of white pan bread added with wheat sprout powder without treatment (WP) and wheat sprout powder with only enzyme treatment (WPE), only lactic acid bacteria treatment (WPL) and enzyme and lactic acid bacteria treatment (WPE&L). The three different powder concentration levels of 1%, 3%, and 5% were added to flour to produce the white pan bread. The bread volume and specific volume of the WPE&L group were the highest among all the addition groups. The bread weight, a-value, and b-value of the WP group was highest among all the addition groups, but the bread baking loss and the L-value of the WP group was the lowest among all the addition groups. The texture measurements indicated that the hardness, gumminess, and chewiness values of the bread were the highest in the WP group. The sensory evaluation test showed that bread in the WPE&L group with 3% wheat sprout powder was the best among all the samples studied. Based on our findings, we suggest that the enzyme and lactic acid bacteria pretreated wheat sprout powder is an effective ingredient for improving the overall quality of white pan bread.

  • To develop functional bread and improve the quality of gluten-free bread, this study investigates the quality characteristics of gluten-free rice bread made from soft-type rice (Bodeurami) flour mixed with black rice at different levels (0%, 10%, 20%, 30%, and 40%, w/w). An increase in the mix level of black-rice flour increased the weight of rice bread but reduced its volume, baking loss, volume expansion, and specific volume. The results for Hunter's color value and texture measurements indicate that an increase in the content of black-rice flour reduced the L-value, the b-value, hardness, gumminess, and chewiness but increased the a-value, adhesiveness, and springiness. According to the sensory analysis, rice bread formulated with a mixture of soft-type rice flour (80%) and black-rice flour (20%) showed the highest scores in color, taste, texture, and overall preferences. With respect to flavor and appearance, bread samples with 20% and 30% black-rice flour were preferred to those with 0%, 10%, and 40% black-rice flour. These results suggest that gluten-free rice bread mixed with wet-milling rice flour and black-rice flour can be used to develop functional and gluten-free bread.
