  • The effects of defatted soy flour on the physicochemical characteristics of dough and bread-making properties were studied with sodium stearyl lactylate(SSL) as an emulsifier. Defatted soy flour was added to the wheat flour at the level of 0$\sim$12%. The emulsifier was added to the wheat flour-defatted soy flour blends at the level of 0.5 and 2%. Set-back and consistency in amylogram were significantly decreased as the level of soy flour was increased. On comparison with control, the bread made from defatted soy flour especially had less specific loaf volume. The specific loaf volume of wheat flour-defatted soy flour bread prepared with 0.5$\sim$2% SSL was better than that without SSL. Decrease of L value (lightness) of crust color and decrease of L value of crumb color were shown with the increase of defatted soy flour. From the result of sensory evaluation, wheat flour-defatted soy flour bread containing up to 6% defatted soy flour with 1.0% SSL were rated as high quality. Most of texture parameters of bread increased with the increase of defatted soy flour and decreased with increase of SSL. Considering the volume and sensory characteristics of bread, bread prepared with 6% defatted soy flour and 1% SSL was regarded as highly acceptable.

  • Green tea powder (3%, 6%, 9%) was added to green tea bread and physicochemical characteristics of green tea bread were investigated. As the result of measuring the pH of the dough, the pH of control was 5.6 and the pH of the investigated. As the result of measuring the pH of the dough, the pH of control was 5.6 and the pH of the samples were 5.34, 5.29 and 5.26 each. As it is seen above, there is no big difference in the pH of the three different dough. Therefore, it could be that the pH of the dough doesn't really affect on the volume of the bread. As the amount of the green powder was changed, the weight of bread, volume of bread, baking loss rate, the color of the surface, the tenderness of the crumb were affected. The 9% of the green powder gave the most distinguishable affect on these factors. As the amount of thee green tea green tea powder caused the change of color. The result of the sensory evaluation showed that the addition of the green tea powder affected significantly on the quality of the bread. Considering the result of the test, 3% of the green tea powder bread is the best for the production of the bread.

  • This study was designed to investigate the possible utilization of Ligularia stenocephala as a source of functional ingredients in white bread. In terms of color values, as more Ligularia stenocephala leaf powder was added, 'lightness,' 'redness,' and 'yellowness' decreased in the crust, while in the bread crumb 'lightness' and 'yellowness' decreased, but 'redness' increased. When 5.0%, 7.5%, or 10.0% Ligularia stenocephala leaf powder was substituted for an equivalent amount of strong flour, the ratio of the volume and specific volume of white bread decreased while its weight increased. In the texture measurements for the white breads, the hardness decreased slightly with the addition of 2.5% Ligularia stenocephala leaf powder, but increased with the addition of 5.0%, 7.5%, or 10.0% Ligularia stenocephala leaf powder. The addition of the Ligularia stenocephala leaf powder also increased the springiness and gumminess of the white bread. The highest sensory scores for color, flavor, taste, texture, and overall acceptance for both the student group and the baker group were obtained from white bread with 5.0% Ligularia stenocephala leaf powder. The highest sensory scores for the housewife group for taste, texture, and overall acceptance were obtained from control bread. Through the results of these experiments, we conclude that the highest quantity of Ligularia stenocephala leaf powder content should be no more than 5.0% when making bread with added Ligularia stenocephala leaf powder.

  • The effects of Crataegus pinnatifida bunge powder(CP) on dough characteristics and bread quality were evaluated. Breads were prepared with the addition of 0, 3, 6 and 9% CP to the basic formulation. The pH of dough added with CP ranged from 5.26 to 5.34, while control dough had a pH of 5.80. The loaf volume index of bread prepared with $3{\sim}9%$ CP decreased by $5.4{\sim}16.9%$ Hardness increased with the addition of CP, but the cohesiveness and springiness decreased with the addition of 3 and 6% CP and increased with the addition of 9% CP. Color L value of the bread crust and crumb decreased with CP and color a and b values of the bread crumb increased with CP. The sensory quality of bread with 6 or 9% Crataegus pinnatifida bunge powder, as estimated by shape, flavor and overall quality, was worse than that of control bread, while bread with 3% Crataegus pinnatifida bungs powder had the best quality.

  • The quality characteristics of breads made by adding levels of 30%, 60%, and 100% aloe gel were investigated. The 60% aloe gel sample had a larger dough volume than the control dough. Also, the loaf volume and specific volume of the bread made with 60% aloe gel were larger than those of the control bread. The pasting temperature increased gradually with the increasing amounts of substituted aloe gel as compared to wheat flour with water added$(66.5{\pm}12^{\circ}C)$; the wheat flour with 100% aloe gel had a pasting temperature of $90.7{\pm}1.1^{\circ}C$. Peak viscosity decreased gradually with increasing amounts of aloe gel when compared to the wheat flour with water added. Setback also was decreased gradually with the increasing amounts of aloe gel as compared to the wheat flour with added water. From the setback decrease it is suggested that the aloe controlled retrogradation of the bread during short-term storage. The crumb color of the bread made with the aloe gel was not significantly different to that of the control bread, and the color of the crumb was yellow-white. Bread hardness decreased gradually with increasing amounts of the substituted aloe gel. However, bread gumminess and chewiness increased gradually with increasing amounts of aloe gel. The springiness of the bread made with 100% aloe gel was lower than that of the control bread. With regard to flavor and taste, the bread made with 100% aloe gel produced a green-like odor and had a bitter taste. The mouth feel of the breads made with aloe gel was considered soft and moist. The overall acceptabilities of the breads made with 30% and 60% aloe gel were not significantly different from the control bread, but the bread made with 100% aloe gel had a green smell and bitter taste. Yet accordingly, the results indicate that functional and health products with improved quality could be developed by adding aloe gel to breads and cakes.

  • The aim of this work was to make acorn bread containing natural antioxidants as healthy food. The amylographic characteristics, loaf volume, color, texture, and subjective preference of the acorn bread containing 5~25% of acorn flour were measured during storage at room temperature and in a freezer. The results were as follows: The loaf volume decreased with increasing the addition of acorn flour from 5% to 25%. The onset gelatinization temperature and the value at the peak point of the bread decreased according to the amount of acorn flour added. L-value decreased with the increase of acorn flour contents, but the a- and b- values increased. During the storage period at room temperature, the L, a, and b- value decreased, whereas in the freezer, the L-value decreased except for the bread containing 5~11% acorn flour. In sensory evaluation, color and taste achieved high scores at 18% addition, but low scores at 25% addition. The bitter aftertaste showed low scores according to the addition of acorn flour. The softness and chewiness decreased, but the overall acceptance increased according to the addition of acorn flour except for the bread added with 25% acorn flour. The textural measurements showed that the hardness, springiness, gumminess, and brittleness increased significantly during the storage periods. The cohesiveness, gumminess, and brittleness in room temperature storage decreased with the increase of acorn flour contents. In freezer storage, the addition of acorn flour resulted in the increase of hardness, springiness, gumminess, and brittleness during storage periods. On the other hands, the cohesiveness decreased with the addition of acorn flour. Moreover the addition of acorn flour increased significantly the hardness, gumminess, and brittleness during storage periods. As a result, the bread containing acorn flour showed reasonable textural properties during storage periods.
