  • Dough fermentation characteristics and quality characteristics of bread added with different concentration(0, 30, 40 and $50\%$ against water) of submerged-culture broth of Fomitopsis pinicola mycelium (CM) were investigated There were positive correlations between CM concentration and dough pH(r=0.98), acidity(r=-0.88), dough thickness(r=0.95) and dough strength(r=0.95). Baking loss rate was decreased with increasing of CM concentration. There was no significant difference between loaf volume index and CM concentration ($30\~40\%$, but the index of CM $50\%$ bread was lower than that of control. L* value of top crust in the CM $50\%$ bread was significantly lower than those of CM $0\~40\%$ bread, while the value of internal tissue was increased with increasing of CM concentration. In the CM $30\~40\%$ bread, hardness was lower, but there were no significant difference in cohesiveness, springiness, chewiness and brittleness compared with control. Appearance, color, taste, texture and overall acceptability of CM $30\~40\%$ bread were similar to those of control. In the results estimated by correlation analysis, the increased pH of the dough by adding CM allowed lowering hardness of the bread By adding CM in bread, retrogradations were delayed, and growth of mold was decreased during storage. In conclusion, the optimum concentration of CM in bread which showed anti-diabetic effect as well as not dropped quality characteristics were $30\~40\%$.

  • This study was conducted to evaluate the characteristics of bread and the rheology of flour dough containing jochung. In the farinogram test, the addition of jochung changed water absorption, development time and mixing tolerance index for making bread As the amount of jochung increased, the water absorption, mixing tolerance index decreased and the development time increased. In the extensograph test, the degree of extension decreased with increasing of jochung content whereas degree of resistance was enhanced with addition of jochung. After fermentation treatment, the volume of the dough with 20% sucrose were less than that of the dough containing 20% of jochung. The dough with 5% jochung showed the lowest dough raising power compared to the other doughs. The bread consisting of 15% jochung showed the highest volume of loaf and specific volume. Therefore, high quality of bread can be achieved by adding jochung instead of sucrose for making bread.

  • This study investigated the effect of roasted rice bran (RRB) on bread quality. Bread containing RRB showed small and specific loaf volumes. Baking and cooling loss rates of bread with RRB were lower than bread without RRB. The pH of bread decreased and total titratable acidity increased with increase in the amount of RRB. Water activity (Aw) and moisture contents of bread increased with RRB levels in bread. Bread containing RRB presented lower L value and higher redness (a) and yellowness (b) values. Crumb hardness, springiness, and gumminess increased, whereas cohesiveness decreased upon addition of RRB. Addition of 5% RRB resulted in higher scores in sensory evaluation than the control, however, bread with 15% RRB had the lowest score. Therefore, 5% RRB can be used in bread production.

  • Cedrela sinensis is a Korean traditional wild herb found especially in the southern provinces of Korea. This study investigated the effects of Cedrela sinensis powder on the antioxidant activities and quality characteristics of bread. Bread was prepared with different amounts of Cedrela sinensis powder (at ratios of 0, 1, 2, and 3% of total flour quantity). The results showed that the dough pH, moisture, and fermentation tension levels decreased as Cedrela sinensis powder content increased. Bread volume and specific volume decreased (p<0.01) with an increasing amount of Cedrela sinensis powder (Bread weight increased (p<0.001)). As Cedrela sinensis powder content increased, color 'a' value decreased, and 'b' value increased. Sensory parameters such as color (p<0.01), flavor (p<0.01), appearance (p<0.001), taste, softness (p<0.05), and overall quality (p<0.01) of bread containing 2% Cedrela sinensis powder were measured. Total phenol contents and DPPH free radical scavenging activity of bread significantly increased with increasing Cedrela sinensis powder content (p<0.001). Based on these results, we suggest that Cedrela sinensis can be used for increasing the consumer acceptability and functionality of bread.

  • The characteristics of colored rice bread using the extruded HeugJinJu rice were studied to establish the optimum formula for the formation of colored rice bread, giving good loaf volume and sensory quality. The expansion ratio and bulk density were decreased, the break strength was increased as the moisture content was increased at extrusion. The gelatinization of extruded HeugJinJu rice was appropriate at 20% of moisture content. The volume of colored rice bread was decreased as the quantity of adding extruded HeugJinJu rice was increased. The weight and hardness of colored rice bread were not significantly different among the groups. The result of measurement of color difference, L value (lightness) was decreased, a value (redness) was increased and b value (yellowness) was decreased as the quantity of adding extruded HeugJinJu rice was increased. As the results of sensory evaluation, color, taste, texture and overall acceptance of colored rice bread were higher than the control group. The best quality giving color, taste, texture, total preference were observed when the extruded HeugJinJu rice was added at l0%.

  • This study was conducted to compare the protein characteristics, dough rheology and bread loaf volume of Korean wheat cultivars and CIMMYT lines produced in diverse environments and to determine the genetic and environmental effects on bread making quality. Protein characteristics, including protein content and SDS-sedimentation volume, mixing properties during dough development and bread loaf volume were primarily influenced by the environment. Wheat cultivated in Jinju exhibited higher SDS-sedimentation volume based on constant protein weight and bread loaf volume than those in Suwon and Iksan. SDS-sedimentation volume based on constant protein weight, mixing time of mixograph and mixing tolerance of mixograph were positively correlated with bread volume. Korean wheat cultivars showed different allelic variations of $Glu-1$ and $Glu-3$ compared to CIMMYT wheat lines. Alchanmil, Keumkangmil and Tapdongmil could be suitable for bread making because these cultivars exhibited a 10 point $Glu-1$ score. However, Korean wheat cultivars should be introduced specific alleles in $Glu-3$ loci, including $Glu-A3b$ or $d$ and $Glu-B3b$, $d$, $f$ or $g$, to improve gluten strength related to increase bread loaf volume.

  • This study was carried out to evaluate the effects of trehalose on quality characteristics of white pan bread. Basic formula consisted of bread flour, 6% sucrose, and 0, 2, 4, 6% trehalose, respectively. Loaf volume, specific loaf volume, baking loss rate, moisture content, water activity, crumb color, and sensory evaluation scores were determined for quality characteristics of bread. White pan bread containing 4% trehalose had a higher loaf volume of 2,140 mL and specific loaf volume of 3.96 mL/g. Baking loss rate of white pan bread was the lowest in the loaf containing 6% trehalose. In crumb texture analysis, hardness of loaf containing 4% of trehalose was the lowest after 7 days of storage. Moisture content and water activity of white pan breads increased with increasing level of trehalose. Color of crumbs was the brightest in the loaf containing 6% trehalose. White pan bread containing 4% trehalose scored better in the sensory evaluation than the others. As a result, trehalose affected quality characteristics of white pan bread. Especially, the addition of 4% trehalose to white pan bread had beneficial effects on quality characteristics.
