  • This study investigated the quality characteristics of the white pan breads with garlic powder. Three different powder concentration levels of 1%, 2% and 3% were added to flour to make the breads. The contents of moisture and crude fat of the breads added with garlic powder were lower than that of control group. However, ash content was not significantly different among groups. The pH increased with increasing garlic powder concentration. The weight of breads increased with increasing garlic powder concentration, while the volume and baking loss rate of breads decreased. In color values, with increase of garlic powder concentration, L value decreased, but a and b values increased. The water activity in the breads decreased by increasing garlic powder concentration was the highest in the control group. In the texture analyzer measurement, hardness of the breads increased with increases of garlic powder concentration, but springiness decreased. In the results of sensory evaluation, the quality of the 1% garlic powder breads showed the highest in taste, flavor and overall acceptability. The color, appearance, mouth feel and texture of the breads decreased with the increasing garlic powder content. From the results of this study, the white breads with 2% garlic powder content was shown to have the best quality.

  • 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.

  • White bread containing lotus root powder was previously reported as unsatisfactory with respect to appearance and chewiness. In this research, white bread samples were prepared using ethanol(2 wt.%) and lotus root powder(3, 6, or 9 wt. %), and compared to those prepared without ethanol (reference breads). The volumes and heights of the reference breads increased with increasing lotus root powder content. The moisture contents of the breads prepared with ethanol were higher than those of the corresponding reference breads. The hardness and fracturability of the breads made with ethanol were lower than those of the reference breads; however, springiness, cohesiveness, adhesiveness and chewiness were enhanced. In terms of appearance and sensory qualities, optimum results were obtained when the ethanol was added along with 6 wt. % lotus root powder. Overall, the results indicate that adding ethanol can improve the quality of white breads that contain lotus root powder.

  • 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.

  • White breads containing Korean blue mussel (Mytilus edulis) powder were prepared and characterized. WB (white bread without blue mussel) and four different MBs (white breads containing blue mussel; number in front of MB means added % of blue mussel powder per wheat flour) were prepared by the straight dough method. With addition of blue mussel to bread, lightness decreased, whereas redness and yellowness increased. Addition of blue mussel did not significantly affect specific volumes of breads. DPPH and ABTS radical scavenging activities significantly increased with increasing blue mussel content. Addition of blue mussel to breads also increased alcohol dehydrogenase and acetaldehyde dehydrogenase activities. In the sensory test, 1MB acquired relatively high points for taste, flavor, texture, and preference. The results indicate that blue mussel can be applied to white bread to improve physiological functions without reduction of physicochemical characteristics.

  • Breadmaking is a complex system in which many variables govern the production of acceptable bread. Lipids, a minor component of wheat flour, function importantly in bread-making. Shortening, or fat, is one of the essential ingredients in commercial baking. Beneficial shortening effect depends on type and quantity of lipids present in wheat flour and also on wheat flour quality. Surfactants have been used in baking industry during last decade because certrain surfactants can replace shortening and/or natural flour lipids. A proper combination of lipidshortening-surfactant is more useful in the production of specialty breads such as whole wheat breads, high protein breads, high fiber breads or even non-wheat composite breads rather than in the production of regular white breads. This presentation is a review of recent studies on the contribution of flour lipids, shortening, and surfactants, alone or in combination in the production of breads; illustrations are mainly from data obtained in the author's laboratory.

  • This study aimed to investigate quality characteristics of white bread with Tenebrio molitor L. powder (TMP). Because of the proximate composition analysis of the white bread with TMP, the content of protein and crude fat increased slightly in proportion to brown dough, and ash was highest in white breads with 7% added TMP. The bread volume decreased as TMP content increased. The control bread lightness was highest at 78.3, and was negatively correlated with the TMP content. The degree of redness increased with the TMP concentration. The total free amino acid contents were in the following order: white bread with 7% TMP > white bread with 5% TMP > white bread with 3% TMP. With respect to the texture, white bread springiness and cohesiveness with TMP decreased by storage period. The chewiness and brittleness of white breads with TMP decreased significantly with higher concentrations. With extended storage, the bread with TMP added showed lower springiness and cohesiveness; while bread with a lower TMP percentage maintained better chewiness and brittleness. The sensory taste preference was highest for white bread with 3% TMP. Residual appetite scores showed a lower taste preference as TMP content increased and was lowest for white bread with 3% TMP.

  • 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.

  • This study investigated the effect of ginseng products on the baking properties of white breads. Flour was substituted by ginseng products (ginseng at levels 2, 4, 6, and 8%, all w/w, of flour levels). Both ginseng powder (GP) and red ginseng powder (RGP) were used. Similarly, red ginseng extract (RGE) was substituted at levels of 1, 2, 3, and 4% (all w/w) of flour. The physical properties of each dough were assessed using farinograms, extensograms, and amylograms. Water absorption increased as the proportions of ginseng products rose. The dough surface areas and R/E (resistance/extensibility) values decreased, as did peak viscosities, at the proportions of ginseng products increased. The pH values during fermentation decreased as the proportions of ginseng products increased. The fermentation power of dough with GP was lower than that of control, and higher than that of dough with RGP or RGE, but the addition of ginseng products beyond certain levels weakened the gas retention power: The specific loaf volumes of breads with 2% GP were the highest at 5.41 mL/g. In breads with RGE, the specificloaf volume increased from 5.52 mL/g to 5.82 mL/g as RGE levels rose from 0% to 4%. Hardness increased with rising GP and RGP levels in breads with GP and RGP, but decreased with RGE levels in breads with RGE. The moisture contents of breads during storage tended to be higher than control in breads with ginseng products. Lightness increased with addition of GP and decreased upon addition of RGP or RGE, while redness and yellowness increased after addition of any ginseng products. In sensory evaluation tests, the sensory scores for texture, color, mouth feel, and overall acceptability, were high, when any ginseng product (GP, RGP or RGE) was present at 2%. Of these breads, the bread with 2% RGE attained the highest sensory score.
