  • This study was carried out to investigate the quality of white pan breads as affected by various amounts of Terminalia chebula Retz (TC) powder, in which the breads were prepared with 0, 2, 4, and 6% TC powder. The samples and a control bread were compared in terms of bread quality characteristics, including pH, baking loss rate, loaf volume index, moisture content, TBARS values, texture, color, and sensory qualities in order to determine the optimal amount of TC powder in the formulation. The pH levels of the bread samples containing TC powder ranged from 5.30 to 5.44, while the control bread had a pH of 5.68. The loaf volume index values of the samples prepared with 2~6% TC powder were lower than that of the control. After 7 days storage, the moisture content of the control bread had decreased by 14.4%, while the moisture contents of the breads with added TC powder had decreased by approximately 8~10%. The breads with TC powder had lower TBARS values as compared to the control bread. For texture characteristics, hardness increased with the addition of TC powder, and was especially increased in the sample containing 6% TC powder. Cohesiveness and springiness, however, decreased with the addition of TC powder. For color, lightness of the bread crust and crumb decreased with the addition of TC powder, whereas redness and yellowness increased. In terms of sensory quality, the bread containing 2% TC powder was preferred over the control bread, as estimated by appearance, crust color, taste, and overall quality, while the 6% TC bread had the lowest preference scores. These results suggest that the addition of 2% TC powder to white pan bread had optimal effects for improving shelf-life and enhancing bread quality.

  • This study was carried out to investigate the quality characteristics of breads with added Phellinus linteus grown in brown rice (BRPL). For color values, with increasing added BRPL powder, "lightness" decreased in the crumb while "redness" and "yellowness" increased ($^{***}$ p<0.001). The highest scores in volume and specific volume were observed in white pan bread with 5% BRPL powder added. When 10%, 15%, and 20% BRPL powder were substituted for equal amounts of strong flour, the volume and specific volume ratios of white pan bread decreased ($^{***}$ p<0.001). In texture measurements for white pan breads, hardness decreased slightly with the addition of 5% BRPL powder, but significantly ($^{***}$ p<0.001) increased with addition of 10%, 15%, and 20% BRPL powder. The addition of the BRPL powder significantly increased the springiness, gumminess, and brittleness of the white pan bread. The highest sensory scores for color, flavor, taste, and overall acceptance were obtained from white pan bread with 5% BRPL powder added ($^{***}$ p<0.001). By the results of these experiments, we can conclude that the hightest quality of bread with added BRPL powder has no more than 10% added BRPL powder content.

  • Daebong persimmon puree (DPP) prepared from removing the astringency of persimmon was used as a substitute for water when making the dough of white pan bread using domestic wheat flour, and the resulting, quality characteristics were investigated. The moisture content of DPP was 96.69%, and the dough was made by various levels of substitution of DPP for water (0, 10, 30, 50 and 100%). During fermentation, the expansion power of the dough decreased with increasing DPP levels (p<0.05). The volume, specific volume, baking loss, and the L and ${\Delta}E$ values of the crust and crumb of the breads also decreased with increasing DPP levels. The hardness and chewiness of the bread containing 100% DPP (without water) showed the highest values, but the springiness, cohesiveness and resilience showed the opposite trends. In the difference tests, all attributes except air cell uniformity were significantly different (p<0.05). Bread made with 100% substitution of DPP for water achieved the highest scores for flavor, taste and overall acceptability.

  • This study was conducted to investigate the effect of baking on the physicochemical and sensory properties of white pan bread with red wine (RW). RW was substituted for water at four levels (0, 19, 38 and 63%). For bread crumb color, lightness decreased with increasing levels of RW, whereas redness and yellowness increased (p<0.05), in proportion to RW levels. Compared to control bread, specific volume of breads added with RW was decreased. The degree of dough raising power decreased significantly depending on the amounts of RW. The hardness of control bread was $87.35g/cm^2$ while the hardness of breads with RW ranged from 85.37 to $94.19g/cm^2$. Hardness, cohesiveness, springiness and gumminess of breads added with RW showed higher scores than the control group. In the sensory evaluation, the highest flavor and taste preference scores were observed in bread containing 38% RW, whereas the lowest score was observed in bread with 63% RW. Accordingly, the quality of bread can be improved by addition of 38% RW substituted for water.

  • Yacon (Smallanthussonchifolius) is a root crop that contains high amounts of fructo-oligosaccharides (FOS). FOS has a sweet taste, is low in calories, and is known to promote intestinal tract health. In this study, various yacon concentrates were substituted for sugar in white pan bread to obtain healthy benefits from the use of FOS. The quality characteristic changes during storage of the white pan breadswith 0, 25, 50, 75 and 100% of added yacon concentrates instead of sugar were investigated. During storage, the water contents and water activities of the breads made with high amounts of yacon concentrates changed less than in those made with only sugar. The hardness and chewiness of the breads made with high amounts of yacon concentrates had lower values than those made with only sugar. Thus, bread made with yacon concentrates might exhibit increased moisture retention and decreased aging velocity. The substitution of yacon concentrates for sugar in pan bread improved the bread quality.

  • This study was carried out to investigate the effects of various salts on the physical and fermentative characteristics of doughs and on the quality of white pan breads produced using purified salt, Korean solar salt, Chinese solar salt, Mexican solar salt, washed and dehydrated salt, roasted salt, and bamboo salt. In farinogram patterns, dough prepared using the purified salt had the highest water absorption. Extensograms showed that the resistances and resistance/extensibility ratios of the doughs with the solar salts were higher than those with the purified salt. In amylograms, the dough with the bamboo salt had the highest viscosity value. A specific volume was the smallest in the bread with the Korean solar salt (4.11 mL/g), while the largest with the Mexican solar salt (4.85 mL/g). A baking loss rate of the bread prepared with the Korean solar salt (10.34%) was less compared to other samples (10.91 $\sim$ 11.65%). The crust of the bread added with the Korean solar salt showed higher L value and lower a value while its crumb showed the highest b value. A sensory evaluation indicated that significant differences in some characteristics of the breads were observed in the breads prepared with the Korean solar salt and Mexican solar salt. However, flavor, taste, and overall acceptability showed no significant differences among all breads prepared with different salts.
