The objective of this study was to determine the optimum manufacturing conditions of whole egg powder with high foaming property sufficient for making sponge cakes. Whole eggs were either desugarized and/or adjusted pH before spray-dried at a temperature of $70^{\circ}C$. The physical properties of the cake were measured, and sensory evaluation was conducted on a 9-point scale. The pH and specific gravities of the foam and batter made from desugarized egg powder did not differ from those of the control, whereas batter made from commercial powder experienced significant loss of cake characteristics. The pH adjustment did not improve the foaming properties of the egg powders. The volume and textural properties of the cakes made from spray-dried egg did not differ from those of fresh egg. The taste and sensory characteristic scores for fresh egg, desugarized whole egg powder, and commercial powder were 5.00, 4.78, and 1.89, respectively. These results indicate that egg powders desugarized and spray-dried at $70^{\circ}C$ are sufficient for making sponge cakes with acceptable physical and sensory attributes.

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 effect of rheological and sensory characteristics of the low-calorie layer cake. It was made with different levels of hydrolyzed oat flour based on the weight of shortening. The specific gravity of cake batter by increasing of hydrolyzed oat flour was decreased. The viscosity, however, was increased. The microstructures of cake crumb observed by the scanning electron microscope showed the decreased number/size of air cells, and the fat particles were also decreased. The texture profile analysis showed statistically significant differences according to the different levels of hydrolyzed oat flour based on the weight of shortening. The hardness, gumminess, and chewiness gradually declined by the increasing hydrolyzed oat flour level while springiness, cohesiveness, and resilience increased. Although taste, texture, and flavor decreased by the addition of hydrolyzed oat flour, it was increased in the appearance, color, and overall preference of the layer cake. Taken together, our results suggest that a 45% addition of hydrolyzed oat flour could be the best replacer for the low-calorie layer cake.

This study was conducted to investigate the effect of rheological and sensory characteristics of the low-calorie layer cake made by adding different levels of polydextrose as a fat substitute for shortening. As the substitution level of polydextrose increased, the specific gravity of the cake batter increased and the viscosity decreased. The microstructures of cake crumb observed by a scanning electron microscope showed the decreased number and size of air cells and fat particles by increasing fat substitution level. The texture profile analysis using rheometer showed significant differences among the samples according to the levels of polydextrose for shortening. The hardness. gumminess, cohesiveness and chewiness of the cake declined gradually by increasing polydextrose level, while the springiness increased. There were no significant differences in resilience. Among various sensory properties, the appearance, flavor, crumb texture and overall acceptance of the layer cake decreased by increasing polydextrose level, although the taste score increased by adding 25% of polydextrose for shortening. Taking these results together, adding 25% polydextrose for shortening suggested to be a good substitution level for the low-calorie layer cake.

The physicochemical properties and mixograph characteristics of soft white winter (SWW) and club wheat, as well as their product potentiality, were investigated. There were no significant differences between the SWW wheat and club wheat regarding their Single Kernel Characterization System (SKCS) properties. The straight-grade flour yield, break flour yield, ash content, and milling score of the SWW wheat were similar to those of the club wheat, and the straight-grade flour yield had a significant positive correlation to the break flour yield (r = 0.805**). The Rapid Visco-Analyzer (RVA) peak viscosity and swelling volume of the SWW wheat flour were very similar to those of the club wheat flour, and there was a significant positive correlation between the RVA peak viscosity and the swelling volume (r = 0.662**). The average mixograph absorption of the SWW wheat was higher than that of the club wheat. The club wheat resulted in a higher cookie diameter than the SWW wheat, but the difference was not significant. The sponge cake volume using the SWW wheat flour was higher than that with the club wheat flour. In addition, there was a significant correlation between the cookie diameter and the sponge cake volume (r = 0.745**).

This study was carried out to investigate the quality characteristics of sponge cakes added with Grifola frondosa powder. The specific gravity, viscosity, and dough weigh tended to increase as the ratio of mushroom powder increased. The sponge cake volume, specific volume, baking loss rate, and height had a tendency to decrease according to the addition of mushroom powder. The color of the cake crust and crumb became darker as the amount of mushroom powder increased, and the addition of mushroom powder increased the hardness, gumminess, and brittleness of the cake. Finally, the overall acceptability of the sponge cake was the best when the cake contained 5% mushroom powder.

This study was performed to evaluate the quality characteristics of sponge cakes in which erythritol were added in order to supply less calories. The sponge cakes were prepared with erythritol as replacement for sucrose with different ratios from 0 to 50%. The specific gravities of the batter with erythritol were higher than those of plain control batter and increased by substitution ratio. The cake volumes were also decreased by the replacement of sugar to erythritol. The addition of erythritol decreased moisture contents of the products. The crude ash and crude protein contents of the cakes were decreased by the substitution ratios. In texture analysis, hardness, gumminess, and brittleness of sponge cake were increased as increasing erythritol were added, while springiness was decreased. Cohesiveness showed no significant differences among the substitution ratios. In the sensory evaluations, the cakes with erythritol revealed high overall eating quality, especially the cakes with 30% erythritol were preferred for taste, odor, texture, and overall acceptability. The results show that the ingredients in sponge cakes were the most recommendable with the substitution ratio of 30% erythritol.

This study was performed to examine the quality characteristics of the sponge cakes with different contents (2-10% (w/w)) of lemon grass powder (LGP). An increase in LGP content in the cake led to a significant increase in the specific gravity of batter, baking loss rate, redness, hardness, cohesiveness, chewiness, and 1,1-diphenyl-2-picrylhydrazyl radical scavenging activity of the cakes and a significant decrease in pH, moisture content, specific volume, height, volume and symmetry index, lightness, and yellowness of the cakes. Springness and resilience did not show any difference between the cakes. The consumer acceptance test indicated that the addition of LGP up to 2% did not cause a significant negative effect on the consumer acceptances in all attributes. The sponge cakes with 2% LGP can be recommended for manufacturing bakery.

Radicchio (Cichorium intybus L.) is widely known to have antioxidant, anti-cancer, and digestion-promoting effects. Antioxidant activity and sensory characteristics of sponge cakes made with radicchio powder were investigated in this study. Sponge cakes were made with freeze-dried radicchio powder added to the flour at concentrations of 1, 3, 5, and 7%. As the amount of radicchio powder increased, the specific gravity of radicchio-containing sponge cakes significantly increased. pH value did not significantly differ between groups. Moisture content decreased from 30.72% (control) to 28.68% (7% radicchio) and loss of mass during baking increased from 7.11% (control) to 9.36% (7% radicchio). L (brightness) and b (yellowness) of sponge cakes decreased while redness increased. Hardness and chewiness decreased as concentration of radicchio powder increased. Springiness and cohesiveness did not significantly differ between any of the groups. Total polyphenol contents ranged from 0.12 to 0.31 mg GAE/g. DPPH scavenging activity significantly increased as the amount of radicchio powder increased. Overall acceptability of sensory experience measured on a 7-point scale was highest in the 3% radicchio cakes (5.35). In conclusion, the addition of 3% radicchio powder improves the sensory qualities of radicchio sponge cakes.
