This study was done to provide the basic information of bread made with curry powder. The amounts of curry powder used were 0 to 3% based on the wheat flour weight. The quality of bread was investigated by evaluation of the specific loaf volume, water absorption capacity, color, sensory quality and texture. The weight of bread decreased with the increase of curry power contents, but there were no significant differences among 0.5, 1 and 2% added curry powder bread. The volume and specific loaf volume also decreased with the increase of curry power contents, but those decreases were not significant between 1% one and 2% one. The water absorption capacities were not affected by the addition of curry powder. The lightness and redness decreased with an increase of curry powder content in the bread, while yellowness increased significantly(p<0.01). The result of the sensory evaluation showed that total acceptabilities of appearance, aroma, texture and taste in the bread with 0.5% and 1% curry powder were significantly higher than the control group and the other groups. Overall quality was negatively affected by the yellowness, odor, hot and bite taste of added curry powder. The factors affecting on the overall quality of the bread with added curry powder were in order of taste quality > curry powder odor > texture quality > aroma quality > springiness > wheat flour odor.
This study was designed to observe the effect of the amount of egg and the specific gravity on the quality of sponge cake. There was a little difference of the moisture content by the specific gravity when the amount of egg was same. However, as the amount of egg was increased at the same specific gravity, the moisture content and baking loss was significantly increased(p<0.05). At 100% of egg amount, the largest specific loaf volume was gained at 0.55 of specific gravity, in the same way 150% at 0.45, 200% at 0.35, 250% at 0.45, The hardness of sponge cake was increased as the specific gravity was increased at the same amount of egg(p<0.05). The specific gravity which the lowest hardness was gained was 0.55 with 100% of the amount of egg, in th same way 0.45 with 150%, 0.35 with 200%. As the period of storage was longer, the increase of hardness was increased as the specific gravity went up at the same amount of egg(p<0.05). Therefore, in the case of sugar content 166%, the specific gravity with maximum specific loaf volume and minimum hardness was gained 0.55 at the amount of egg 100%, 0.45 at 150%, 0.35 at 200% and 0.35 at 250%.

Functional bread was manufactured with single cell detritus (SCD) of sea tangle. The optimum ingredient formula for SCD bread was determined based on mixture model. Flour and water reduced max weight, strength, hardness and specific loaf volume, whereas the increased SCD reversed the volume change of dough. Flour increased $L^*$ and $b^*$ values of SCD bread, while SCD decreased. Flour and water decreased $a^*$ value, while SCD increased. Max weight, strength, hardness, specific loaf volume, $b^*$ value and water holding capacity (WHC) were linear model on ANOVA table, whereas distance, volume change of dough, $L^*$ and $a^*$ values were nonlinear model. The response constraint coefficient showed that SCD influenced texture of SCD bread more than flour and water did, whereas water influenced the volume change of dough, specific loaf volume and WHC more than flour and SCD did. Moreover, flour influenced color value more than did water and SCD. Distance and $a^*$ value fitted nonlinear model with interaction terms for flour-SCD and water-SCD. Optimum ingredient formula for SCD bread was: flour, 48.25%; water, 30.89%; SCD, 3.86%. Sensory evaluation of SCD bread was a little lower than industrial bread and electrolyzed SCD bread.

Effects of adding of Angelica keiskei Koidz flour on the quality characteristics of bread were inves tigated. The content of total dietary fiber was 31.89% in flour of Angelica keiskei Koidz leaf and 43.37 % in that of stem. The content of insoluble dietary fiber increased by blanching, but those of soluble dietary fiber and insoluble dietary fiber increased by steeping in NaCl solution. In the results of sensory evaluation of Angelica keiskei Koidz flour, leaf steeped in NaCl solution and blanched stem showed good overall preference. With the addition of Angelica keiskei Koidz flour, water binding capacity and loaf weight increased, while the loaf volume decreased. The loaf volume of bread added with leaf steeped in NaCl solution and blanched stem were higher than those added with natural Angelica keiskei Koidz flour. The lightness and redness values decreased with the increase of Angelica keiskei Koidz flour content in bread but yellowness values increased. In the texture analyzer measurement for bread added with Angelica keiskei Koidz flour, hardness and springiness somewhat increased, while cohesiveness, gumminess and chewiness decreased. As the results of sensory evaluation of bread added with Angelica keiskei Koidz flour, the score of the breads added with 5% leaf steeped in NaCl solution and 5%, 10% blanched stem were somewhat lower than those of control bread. In terms of rate of addition of Angelica keiskei Koidz flour, the bread added with leaf at 5% level, natural stem at 5% level and stem by blanching at 5%, 10% level had good overall preference.
Oat flour was purchased and investigated for quality characteristics of oat bread. Antioxidant and flour pasting properties of oat flour, and water content, weight, volume, Hunter color value, texture of bread were measured. DPPH radical scavenging capacity (%) of oat extract was 68.49%. Pasting temperature of oat flour ranged between $66.60^{\circ}C$ and $70.93^{\circ}C$. Flour pasting properties of sample added with 10 and 30% oat flour was shown similar results compared with wheat flour. Final viscosity of sample was increased by adding concentration of oat flour (up to 311.65 RVA). Water content (%) of bread was shown increasing trend by adding oat flour. Weight of bread loaf with 100% oat flour was shown higher score than other samples. Volume of loaf by adding oat flour of 10, 30, and 50 % ratio was 550, 450, and 388 mL, respectively. The Hunter color $L^*$ values of bread by adding oat flour was dark compared with wheat bread. Color value of bread added 10% oat flour was similar results with $L^*$ values of bread with wheat flour. The bread added with 20 and 30% oat flours had the higher hardness, gumminess, and chewiness compared with other samples. Cohesiveness of the bread with wheat flour showed higher than that of bread added with oat flour and increased by storage period. The growth of total viable cell was inhibited depending on the concentration of oat flour during storage.
Effects of adding of dandelion flour on the quality characteristics of bread were investigated. Dandelion flour was substituted at levels of 0, 0.5, 1.0, 2.0% to wheat flour for bread making, respectively. Quality characteristics of bread such as dough yield, dough microstructure, loaf volume, bread yield, crumb color, mechanical property and sensory evaluation were analyzed. Addition of dandelion flour to wheat flour increased dough yield, loaf volume and bread yield. And, addition of dandelion flour caused a decrease in the lightness and an increase in the redness. The results of texture evaluation revealed that hardness, chewiness, springiness of bread increased as the level of dandelion flour was increased. As the addition level of dandelion flour increased, flavor balance, bitterness, aftertaste, grassy odor of bread increased but overall acceptability, moistness decreased. In conclusion, bread with 0.5% leaf powder was the best quality in bread properties.
The objective of this study was to investigate the influence of adding Gastrodiae rhizoma powder on quality attributes of sponge cake. The cake was made with various Gastrodiae rhizoma powder concentration(0.5%, 1%, and 1.5%) added, and it was stored for 5 days at three different temperatures(5, 15, and $25^{\circ}C$). By analyzing the mixogram data of wheat flour-Gastrodiae rhizoma powder composite flour, the ascending angle of the samples containing Gastrodiae rhizoma powder was increased and the descending angle had upper values compared with that of control as the Gastrodiae rhizoma powder addition concentration was increased. The loaf volume of 0.5% Gastrodiae rhizoma powder slightly increased by 5.1% but those of 1% and 1.5% were slightly decreased compared with that of the control. Crumb firmness of the control showed relatively high value compared with those($5{\sim}6\;N$) of other samples containing Gastrodiae rhizoma powder regardless of storage temperature and storage period, and the firmness after 5 day storage at $5^{\circ}C$ showed the highest value(about 9.3 N). Sensory evaluation attributes of sponge cakes did not show significant difference by Gastrodiae rhizoma powder addition up to concentration of 1.5%.
This study was carried out to examine the effect on the contents of dietary fiber, mechanical properties, and sensory quality of bread contained with 10% of high-fiber Camellia (Camellia japonica L.) seed flour. Bread added by dietary fiber was the contents of moisture, protein and ash higher than control bread, while the contents of lipid lower than that of control bread. The high-fiber with Camellia seed flour contained 8.6% soluble dietary fiber, 43.7% insoluble dietary fiber, and 52.3% total dietary fiber. The ratio of insoluble dietary fiber/soluble dietary fiber in the high-fiber with Camelia seed flour was 5 times. Bread with the addition of dietary fiber contained 6.9% total dietary fiber. With the addition of dietary fiber, water absorption , mixing time loaf weight, and hardness increased, but the loaf volume decreased . The sensory quality on bread added by dietary fiber was somewhat low in color, appearance, crumb texture, mouthfeel, flavor and overall preference was higher than that of control bread.
The replacement of wheat flour with 4 to 24% soy fiber FIBRIM(R)1450 was evaluated to determine its effect on the properties of sponge cake. The volume and specific loaf volume decreased as the amount of soy fiber increased. In addition, the protein content and water holding capacity (WHC) were negatively correlated with the specific gravity of batter and the specific loaf volume of sponge cake, whereas there was no correlation between the mixograph characteristics and specific loaf volume of sponge cake in response to the addition of soy fiber. Furthermore, the symmetry and uniformity indices were not influenced by the addition of soy fiber. However, the L values of sponge cake crust and crumb decreased with increasing amounts of soy fiber, whereas a and b values were not affected. Additionally, the hardness, gumminess, and chewiness of the sponge cake all showed positive correlations with the protein content, sedimentation value, WHC and alkaline water retention capacity. Finally, the results of sensory evaluation indicated that external and internal colors, grain, texture, and flavor were not influenced by the addition of soy fiber, but that supplementation with over 20% soy fiber resulted in a slight decrease in taste and overall acceptability.
The purpose of this study is to promote the substitution of rice flour for wheat flour in making bread and thus the consumption of rice by examining the effect of particle size of rice flour on leavening rice bread. For this purpose, several experiments were carried out. With regard to particle size distribution, 59.45% of wheat flour had passed 200 mesh and 3 kinds of rice flour milled to penetrate into 20, 35, and 45 mesh (S1, S2 and S3) had passed 21.88%, 33.1% and 36.38% of those for 200 mesh, respectively. To leaven the rice flour dough to bread, 25% of vital gluten was needed. To determine the optimal water quantity for rice bread dough, the hardness of wheat and rice flour dough was measured by rheometer. The appropriate water quantity for S1, S2 and S3 was set at 285 ml , 295 ml and 335${\sim}$340m1, respectively. The loaf volume index of the wheat flour bread was 6.24, while that of and rice flour bread S1, S2 and S3 was 5.38, 5.50 and 5.75, respectively. These results indicated that the loaf volume index of rice flour bread is lower than that of wheat flour bread, but that the volume of rice flour bread was increased with fuel particle size of rice flour. Scanning electron microscopy (SEM), image of the wheat bread tissue at a magnification of 35 times showed long, large, oval-shaped, air cells and thin cell membrane, as well as small air cells, whereas the images of rice flour showed angular, circular, air cells and rough and thick cell membrane. The size and number of air cells in the rice bread were larger in S2 and S3 with fuel particle flours than in S1. In particular, the bread made with S3 contained many air cells that were as large as those in the wheat bread were. In addition, when the inner cell wall was magnified 1500 times, almost no small air cell was observed in C and S3, whereas many fine air cells were observed in the cell wall of S1 and S2.
