  • Baking properties of Korean domestic wheat flour supplemented with pine pollen powder were investigated. Farinographic characteristics showed that the addition of pine pollen increased water absorption without any changes in dough development time and stability of dough in comparison with control. A higher gelatinization temperature and a lower maximum viscosity of dough on amylogram were observed with pine pollen powder addition. The addition of pine pollen powder showed decrease in redness and increases in lightness and yellowness of bread crumb. A significant increase in bread volume was observed as the pine pollen powder added more. Springiness. cohesiveness and resilience of bread were increased by pine pollen powder. Sensory evaluation of bread showed that the addition of pine pollen powder, especially at the level of 1%, enhanced color, mouth feeling, bleak and appearance without significant reduction of overall acceptability.

  • This study was conducted to investigate the quality and antioxidant properties of white breads enhanced with broccoli powder (BP) (0%, 2.5%, 5.0%, 7.5% and 10.0%). L-value significantly decreased with increasing levels of BP, but a- and b-values increased (p<0.05). Baking loss rate, bread volume, and specific volume were reduced with the addition of BP, whereas the pH of the dough and bread weight increased. The hardness, gumminess and brittleness of breads with BP were higher than those of control breads (p<0.05). Upon sensory evaluation, the 2.5% and 5.0% BP breads showed no significant differences in color, flavor, taste, texture, or overall acceptability compared with controls (p<0.05). The 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity of bread significantly increased with increasing BP content (p<0.05). Accordingly, bread quality can be improved by the substitution of 5% BP in place of flour.

  • 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 presents the quality characteristics of blueberry bread. Blueberry fruit powder was added to bread dough at various concentrations ranging from 3~9%, after which physicochemical properties of dough and bread containing blueberry fruit powder were determined. The pH, loaf volume, specific loaf volume, dough volume and baking loss decreased with increasing amount of blueberry fruit powder in bread, whereas loaf weight and hardness were reduced. In particular, hardness appeared to be 1.98 times higher in the control without blueberry powder compared to the bread containing 9% blueberry powder. For color, increasing the amount of blueberry fruit powder reduced L and b values, whereas a value was increased. In the sensory evaluation, the highest overall preference score was observed in bread containing 6% blueberry powder, whereas the lowest score was observed in bread with 9% blueberry powder. From these results, blueberry bread with good acceptability has an optimum blueberry powder concentration of 6%.

  • In this study, domestic wheat white breads were prepared with the substitution of 1.5, 3.0, 4.5, and 6.0% Nelumbo nucifera G. tea powder(NNTP). The samples and a control were then compared with regard to quality characteristics, including pH, total titratable acidity, fermentation power of dough expansion, specific volume, baking loss, moisture content, color, textural characteristics, external and internal surface appearances, and sensory qualities in order to determine the optimal ratio of NNTP in the formulation. As the NNTP contents increased, the pH of dough and bread, baking loss, and lightness decreased, whereas the total titratable acidity of dough and bread increased. The fermentation power of dough expansion increased with increasing incubation time. The NNTP samples evidenced significantly higher specific volume, greenness, yellowness, resilience, and crumb consistency than were observed in the control group. However, hardness and fracturability evidenced the opposite effect. The water content and uniformity of the crumb pores were highest at a substitution level of 1.5%, and were lowest at a level of 4.5%. Crumb color, flavor, and delicious taste decreased with increasing NNTP contents, whereas lotus leaf flavor, astringency, bitterness, and off-flavor increased. Density of the crumb pore and crumb springiness were not significantly different among the samples. Softness, chewiness, and overall acceptability were maximal with the 1.5% substitution, and were minimal in the 6.0% group. In conclusion, our results demonstrate that $1.5{\sim}3.0%$ NNTP may prove quite useful as a substitute for domestic wheat flour in the production of white bread, and may evidence favorable nutritional and functional properties.

  • Husked barley contained 17.2% dietary fiber and naked barley contained 14.9% dietary fiber. The barley was ground in a Udy cyclotec mill having a 0.5 mm screen and sieved with a 400-mesh screen (38 m openings). Coarse material of naked barley retained by the screen, with a weight yield of 54.1%, contained 7.0% soluble dietary fiber, 13.9% insoluble dietary filer and 20.9% total dietray fiber. As the naked barley flour level increased in bread baking, the water absorption, mixing time, and loaf weight increased, but the loaf volume decreased. Barley flour was added to wheat flour at a replacement level of 10% without a large adverse effect on bread quality, and the dietary fiber content of bread was increased from 3.0% to 5.0%. The soluble dietary fiber content was not changed, but the insoluble dietary fiber content was increased during the baking process.

  • Rheological properties of the dough made from milled wheat products of various particle size, i.e., wheat shorts, girls and flour, and their effect on the loaf-volume potential of whole wheat bread were investigated in this study. One Korean wheat variety 'Cho-Kwang' was tested for suitability in whole wheat bread. The percent ash and protein content of the milled wheat products were 2.3% and 13.7% respectively. Ranges of 7.3, 5.6 and 4.8 mixograph peak-height were observed in Fraction 1(wheat flours), Fraction 2 (wheat girts) and Fraction 3(wheat shorts), respectively. Dought stability of Fraction 1 did not decreased appreciably as compared to that of commercial first grade baker's flour. Bread-baking test employing a standard formula showed that the wheat grits (0.2-0.5 mm in diameter) appeared to be the limit beyond which a rapid decrease in loaf-volume potential was noted. Optimum loaf volume and crumb characteristics were obtained in 80% wheat grits/20% wheat flour blend.

  • To develop and industrialize functional foods containing peanut sprout extract (PSE) and powder (PSP), the present study investigated the quality characteristics and antioxidant effects of breads prepared with 0, 0.5, 1, 2, 2.5, 5, 7.5, and 10% PSE and PSP. The expansion ratio of the dough, the quality characteristics such as volume, weight, specific volume, baking loss, color, texture, and sensory preference were evaluated. There were significant differences in the bread volume and specific volume among the control, PSE and PSP groups (p<0.001). Additionally, the weight and baking loss were decreased with an increasing amount of PSP (p<0.001). As the amount of PSE and PSP were increased, the L value of the crumb decreased, whereas the a and b values of the crumb significantly increased (p<0.001), suggesting that the crumb color of the bread may be significancy (p<0.001). As the amount of PSE and PSP increased, the hardness of bread significantly and rapidly increased from 5%. Meanwhile, there was no significance in springiness among the control, PSE and PSP groups. The total resveratrol content and DPPH free radical-scavenging activity of the bread significantly increased depending on the amounts of PSE and PSP (p<0.001). In the overall acceptance test, no significant differences were observed in the color, flavour, or texture, however, the taste and overall acceptance were significantly decreased between the control and the PSE group. All the sensory characteristics in the PSP group were significantly reduced compared with the control. Considering the above results, it can be expected that the suitable amount of PSE and PSP substituted for wheat flour will be from 1.0 to 2.5%. Furthermore, follow-up studies are being carried out continuously.
