  • This study was conducted to evaluate quality characteristics of white breads with Acanthopanax senticosus extract(ASE) (0, 25, 50, 75 and 100%). Addition of ASE significantly decreased L-value, and increased a and b-values. Compared with the control bread, specific volume of bread added with ASE was increased. The cohesiveness, springiness and gumminess of the breads added with ASE were higher than those of the control group. Also, a sensory evaluation was carried out in terms of acceptability(color, flavor, taste, texture and overall acceptability). Taken together, the 50% treatment ranked the highest evaluation values, as compared to other treaments. Accordingly, to improve the quality of bread, it is recommendable to add ASE to the 50% level in substitution for water in making a loaf of bread. After all, this study was to confirm the possibility of ASE's utilization as natural materials containing the functional substance.

  • The effects of defatted soy flour on the physicochemical characteristics of dough and bread making properties were studied. Defatted soy flour is added to wheat flour for bread-making in order to maximize the use of isoflavones in the soybean. Different particle sizes of both defatted soy flour and wheat flour were prepared by grinding and sievingwith meshes. In the mixograph test, the addition of defatted soy flour to wheat flour increased the requirement for water and decreased the dough development time. Water absorption rates were also investigated to determine the optimum quantity of water for good dough. As the level of defatted soy flour mixed with wheat flour increased, the sedimentation and P.K. values decreased. In comparison with control, the bread made with defatted soy flour especially had a lower specific loaf volume. Specific loaf volume of wheat flour-defatted soy flour bread prepared (Ed- this is an incomplete sentence, it's only a subject clause, and I don't how what you intend to state). In terms of the staling rate and hardness of the wheat flour-defatted soy flour bread, the increased defatted soy flour had a faster staling rate during storage at 5? than at 25? for 5days. From the result of sensory evaluation, wheat flour-defatted soy flour breads containing up to $4\%$ defatted soy flour were rated as being of high quality.

  • This study investigated the neuroprotective effects of bread containing extract from Cirsium setidens (CS) or Aster scaber (AS) against $H_2O_2$-induced death of human brain neuroblastoma SK-N-SH cells. Treatment with bread containing extract from CS (CSB) or AS (ASB) reduced $H_2O_2$ cytotoxicity in SK-N-SH cells, the intracellular ROS level, and the phospho-p38 mitogen-activated protein kinase (MAPK) level. In the sensory evaluation, wild vegetable flavor scores of CSB were higher than those of ASB and bread containing 0% CS or AS (NB). In terms of appearance, color, flavor, softness, and overall acceptability, CSB and ASB showed higher scores than NB, but no differences were observed between CSB and ASB. These results indicate that CSB and ASB have potent health benefits in terms of neuroprotection against oxidative stress mediated through antioxidant activity and inhibition of p38 phosphorylation in brain neural cells. Thus, CS and AS could be considered as a health functional material.

  • Breads were prepared with the addition of sprouted brown rice flour(SBRF) as a funtional ingredient up to 50%, and their quality characteristics were evaluated through analyses of proximate composition amino acid by HPLC, fatty acid by GC, and sensory evaluation. The optimum amount of SBRF for bread preparation was 30%(w/w). The more SBRF was added, the greater the proximate components such as ash, crude protein, crude fat, fiber and amino acid content were, although the baking quality such as volume decreased. The results of sensory evaluation for bread showed that the more SBRF was added, the lower the scores of color, appearance. texture and the feelings in the mouth were, but the higher the score of taste.

  • This study was carried out to investigate quality characteristics of white breads with cabbage powder(CP) (0, 2.5, 5.0, 7.5 and 10.0%). L-value was significantly decreased by addition of CP, but a and b-values were increased(p<0.05). The degree of pH of dough and bread weight increased with increasing CP concentration, while bread volume, specific volume, and baking loss rate became reduced. The hardness of the breads added with CP was higher than that of the control group. Also, In sensory analysis, the breads with CP showed generally low scores in color, flavor, taste, texture and overall acceptability compared with the control. Taken together, the 2.5%, 5.0% treatment showed similar results with the control group, as compared to other treatments. Addition of CP influenced the color, bread volume and other rheological properties, which is disadvantageous for the quality of white bread. However, compared with the control group, up to 5% CP substitution for flour didn't show significant defferences in sensory test.

  • Quality characteristics of white bread added with lotus root powder(3, 6%) were investigated. Moisture content of white bread added with lotus root powder were higher than control. As the amount of added lotus root powder increased, the lightness, redness and yellowness of bread crust as well as the volume of the bread decreased, but the redness and yellowness of the crumb increased slightly. The content of free amino acids increased by the addition of lotus root powder and the major ones were L-glutamic acid, L-alanine, L-valine and threonine. The major flavor components were 2-methyl butanal and 3-methyl butanal, which were formed by the amino-carbonyl reaction in baking bread at high temperature. Aldehyde flavor components such as 2-ethylfuran, 2-butanedione and 3-butanedione were formed by yeast fermentation. Ethyl acetate and vinyl acetate also influenced the flavor of the bread. The addition of lotus root powder increased the hardness and fracturability, and decreased the gumminess, chewiness and cohesivenes of the bread. Sensory evaluation of white bread indicated that the addition of 3%, 6% lotus root bread enhanced the grain formation, color, mouth feeling, appearance, hardness, moistness, flavor and overall acceptability. Overall, the addition of 6% lotus root powder showed the best performance in the nutritional and functional aspects of the bread.

  • The effects of Angelica gigas nakai powder on bread quality during storage period were evaluated. Breads were prepared by the addition of 0, 0.5, 1, 2, 3, 5 and 10% of Angelica gigas nakai powder to flour of the basic formulation. The moisture, crude protein, crude fat and crude ash contents of the bread decreased by increasing amounts of the Angelica gigas nakai powder were the lowest in the control group. There were no significant difference in pH of the bread among each experiment groups. The weight of bread increased with increasing Angelica gigas nakai powder concentration, while the volume of dough decreased. In color values, with increase of Angelica gigas nakai powder concentration, L value decreased in the crust and crumb, but a and b values increased. As the results of texture, hardness, gumminess and chewiness were increased with increase of Angelica gigas nakai powder concentration, but adhesiveness, springiness and cohesiveness were decreased. Softness in the crumb stored for 1 or 7 days was the highest for the bread made with 2% Angelica gigas nakai powder, and chewiness was the lowest for the bread made with 5% Angelica gigas nakai powder. The water activity in the bread stored for 3 days was the highest for the breads made with 2% and 3% Angelica gigas nakai powders. After 7 days, the water activity tended gradually to decrease. In the results of sensory evaluation, the quality of the 0.5% or 1% Angelica gigas nakai powder bread showed the highest in taste and flavor. The color, taste, flavor, appearance, texture, and overall acceptability of the bread decreased with the increasing Angelica gigas nakai powder content. Considering the able outcome, the addition of Angelica gigas nakai powder by 0.5% and 1% is thought to play a role as a functional breads, along with the improvement of quality.

  • This study was carried out to investigate the quality characteristics of bread containing Houttuynia cordata Thunb. powder (HTP; in ratios of 0, 0.3, 0.5 and 1.0% of the total flour). We found that addition of HTP decreased the pH of dough, whereas the pH of bread remained unchanged. HTP caused no significant change in dough volume during fermentation. Baking loss did not show significant difference between HTP containing bread and control. However, we found changes in bread volume with the most pronounced decrease observed in bread containing 0.1% HTP. Lightness and redness of the inner crumb were decreased by the addition of HTP, whereas yellowness was increased. 2,2-diphenyl-1-picrylhydrazyl-radical scavenging activity and total polyphenol contents were increased significantly by the addition of HTP. The overall acceptability of bread containing 0.5% HTP was better than that of control.
