  • This study was carried out to investigate the quality characteristics and antioxidative activity of bread containing lotus leaf powder (in ratios of 0, 1, 2, and 3% of the total flour). The pH of dough and bread were decreased as the concentration of lotus leaf powder increased. The volume of dough during fermentation did not show significant difference between 1% lotus leaf powder containing dough and control. The weight of bread increased by addition of lotus leaf powder. The volume, specific volume and baking loss rate of the bread decreased as lotus leaf powder levels increased. Redness and yellowness of the inner crumb were decreased by the addition of lotus leaf powder, but lightness was increased. 2,2-diphenyl-1-picrylhydrazyl-radical scavenging activity and total polyphenol contents were increased significantly as the concentration of lotus leaf powder increased. The overall acceptability of bread containing 1% lotus leaf powder showed no significant difference compared with control. The result exhibited that adding the lotus leaf powder into the bread increased antioxidant activity, and the highest quality improvement was obtained by incorporating 1% (w/w) lotus leaf powder into the bread formula.

  • The purpose of this study was to investigate the quality characteristics, antioxidant activities and sensory properties of sponge cake with cabbage powder (CP). Physicochemical and sensory properties of sponge cake with different amount (0%, 5%, 10%, and 15%) of CP were examined. As the increase in the amount of CP addition, the specific gravity and baking loss rate were increased, whereas the color of the cake crumb and crust, volume index and specific volume were decreased (p<0.05). The symmetry and uniformity index of the sponge cake were not affected by the addition of CP (5-15%) (p<0.05). The hardness was significantly increased while by CP addition cohesiveness was decreased (p<0.05). The springiness, gumminess and brittleness were not changed by CP addition (p<0.05). The total polyphenolic, DPPH radical scavenging activities and reducing power were significantly increased by addition of CP at high concentrations (p<0.05). In the sensory evaluation, addition of CP significantly degraded the panel preference related to the color, flavor and texture of the sponge cake. However, the highest point were given to sponge cakes containg 5-10% of CP in taste and overall acceptance (p<0.05). These data suggested that adding 5% of CP is the optimal concentration overall for making sponge cake. However, the sponge cake with 10% of CP is recommended in order to maximize antioxidant activity, the sponge cake was the best when contained 5% CP and the sponge cake prepared with the addition of 10% CP was recommended to use due to its advantages in functional property.

  • This study was carried out to investigate the quality characteristics of bread containing sweetpotato (Ipomoea batatas (L.) Lam) leaf powder (0, 2, 3, 5, and 7% of the total flour). We found that the addition of sweetpotato leaf powder decreased the pH of the dough, whereas the total titratable acidity increased and the specific volume and baking loss of bread were decreased. However, the moisture content of the bread did not show any significant differences. The L and a values of the bread inner crumb were decreased by the addition of sweetpotato leaf powder, however, the b value was increased. The 2,2-diphenyl-1-picrylhydrazyl-radical scavenging activity, total polyphenol, lutein and ${\beta}-carotene$ contents were increased significantly by the addition of sweetpotato leaf powder. The taste, color, flavor, chewiness and overall acceptability of bread containing 2~3% sweetpotato leaf powder were better than those of the controls. We found that the sample group with 2~3% sweetpotato leaf powder is the optimum content for making bread.

  • The purpose of this study was to investigate the quality characteristics of sponge cake with broccoli (Brassica oleracea var. italica Plenck) powder. Broccoli powder was mixed with wheat flour at various ratio (3, 5, 7, 9%, w/w) for physical and sensory evaluations. The specific gravity of bread dough increased with added broccoli powder. The moisture of the sponge cakes with added broccoli powder was higher than that of control. In the crumb color values, lightness (L) and redness (a) decreased upon broccoli powder addition, whereas yellowness (b) significantly increased (p<0.05). In the texture analysis hardness, cohesiveness, springiness and gumminess were reduced by addition of broccoli powder. When we evaluated the sensory characteristics of five subareas (color, flavor, texture, taste, and overall acceptability), 7% broccoli sponge cake showed the highest sensory properties except for flavor (p<0.05). Therefore, the results suggested that 7% broccoli sponge cake could be helpful in improving physical quality and taste.
