The effect of commercial Doenjangs (Korean soybean pastes) on sponge cake making was studied. When Doenjang was added to e99 foams at levels of 5, 10, 15 and 20%, there were no big differences in viscosity or stability of egg foams up to 15%, and thus in cake volume index, compared to those of control (without Doenjang). In the results of preference rank test, cake with 10% Doenjang was preferred to the other cakes. Therefore, it was decided that the addition of 10% Doenjang was suitable for sponge cake making. When seven commercial Doenjang products were used at 10%, there were differences in physical and sensory properties. The decreased viscosity of egg foams reduced their stability and so decreased the quality of the sponge cakes with low volume index and low texture scores. The use of Doenjangs improved the flavor of sponge cake and so countervailed the undesirable egg flavor. Especially, “C” Doenjang product, which increased the viscosity and stability of egg foams, produced good foaming ability and the highest physical and sensory quality, thus the higher overall acceptable scores than the control. It was probably due to its high amount of protein hydrolysate above 10-KDa. Consequently, the suitable amount of Doenjang was fixed at 10% and “C” Doenjang product was chosen as the best among the commercial products for sponge cake making.

The purpose of this study is to examine the change of the shape of sponge cake in proportion to the raw material mixture and the degree of dough. It is examined that the measures of the degree of dough in proportion to the material mixture, and the sense examination and measure of moisture with this sponge cake. The test results indicate that 50% sponge cake is most soft among the ratio of other material mixtures, and sponge cake is more soft as the degree of dough is lower. Therefore, the shape of sponge cake is greatly changed in proportion to the mixture of materials and the degree of dough.

Effects of oligosaccharides substituted for sucrose on the sponge cake quality were investigated. Fructooligosaccharide and isomaltooligosaccharide were used as oligosaccharides. Oligosaccharides decreased batter specific gravity, and increased cake specific volume and expansion ratio, showing that oligosaccharides had higher foaming ability and foam stability than sucrose. Oligosaccharides darkened the crust and crumb color of cakes. Addition of oligosaccharides made cakes darker, softer, more moist and more acceptable as perceived by panels. The acceptability was significantly correlated with crust and crumb color, softness, moistness and flavor(p<0.01). The textural characteristics including hardness, chewiness and gumminess of cakes were decreased by replacing sucrose with oligosaccharides. The hardness, gumminess and chewiness among sensory characteristics were negatively correlated with acceptability(p<0.05). Therefore, oligosaccharides should be a good alternative for sucrose in cake making because the sponge cake quality was greatly improved by partial repacement of sucrose with oligosaccharides.

In this study the replacement of wheat flour with 5 to 30% black rice flour was tested to examine its effect on sponge cake making properties. We evaluated the effects of the substitutions on various quality parameters of the cake, such as physicochemical and rheological properties, cake making quality, and texture characteristics. The water holding capacity value increased with increasing amounts of black rice flour, whereas the alkaline water retention capacity, Pelshenke value and sedimentation value decreased. The mixograph peak time and peak height, and the Rapid Visco Analyser peak, minimum, and final viscosity decreased with the addition of black rice flour. Increasing proportions of black rice flour resulted in reduced loaf volume. However, replacing 15% of the wheat flour with black rice flour did not significantly affect the characteristics of the sponge cake. The textural characteristics of the sponge cake crumb were influenced by the addition of black rice flour, and sponge cakes containing the additives showed increases in hardness, gummines, and chewiness.

The principal object of this study was to assess the effects of garlic powder(2 % and 4 %) on the sponge cake made with medium and cake flour. After making sponge cakes with garlic powder, water activity, softness, color of crumb, and sensory test were tested. Water activity(Aw) of the sponge cakes with different quantity of garlic powder were increased during 7 days storage. These meant that garlic powder had absorption effect. The Max G and springiness of the sponge cakes with garlic powder were all lower than that of the control. With regard to the color of the sponge cakes, the L values were reduced, but the a and b values were increased with the increment of percent of garlic powder. The micrographs of the sponge cakes with garlic powder evidenced slightly lower porosity than the control. And, the results of sensory test showed that the increment of the addition of garlic powder had low scores. But we know the possibility to make the sponge cakes using garlic powder. And the sponge cakes with medium flour using 2% of garlic powder had better evaluation than others using garlic powder.

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.

Dangyuja (Citrus gradis), a native citrus fruit of Jeju Island, has sour and bitter tastes. Dangyuja is rich in dietary fiber and enhance antioxidant activity. In this study, sponge cake was prepared by adding Dangyuja peel powder, and its quality characteristics were investigated. The freeze-dried Dangyuja peel powder was added to sponge cakes at a content of 0% (control), 2% (DP2), 4% (DP4), 6% (DP6) and 8% (DP8) of wheat flour weight. The specific gravity and baking loss of dough tended to increase with the amount of Dangyuja peel powder added, but the pH value as well as volume index of the cake were decreased. The symmetry index of cake tended to increase. Color values of sponge cake crust showed no significant difference, but L value and a value of crumb were decreased. The hardness and chewiness were increased with adding Dangyuja peel powder. Springiness was the highest at DP2 (91.79%). Cohesiveness did not showed significant difference among all samples. In a consumer preference test, cake groups with Dangyuja peel powder was higher than DP0 in color, texture, and overall acceptability. From these results, it was concluded that Dangyuja affects characteristics of sponge cakes. When making Dangyuja peel sponge cakes, it is suitable for adding 4% Dangyuja peel powder.

This study was carried out to investigate the optimum conditions for making “sponge cake” with addition of ingredient, laver powder, and the quality characteristics of a new sponge cake. The moisture contents of sponge cake with 2, 4, 6% laver powder did not change but with 8 and 10%, the moisture contents increased to 28.89% and 30.69%, respectively. While specific gravity increased to 0.674 (control 0.493) when 10% laver powder was added, but volume was decreased. Most abundant mineral was Ca, followed by Na, Fe, Mn, Cu and Zn. The crust color degree of sponge cake with laver powder showed low marks on L, a, b. The crumb color degree showed low marks on L, b while “a” degree redness indicated highest marks with 4% laver powder. When it was seen under the microscope, the air cell numbers were decreased but the cell size became bigger. More free amino acid was contained when the laver powder was added. L-glutamic acid, L-alanine, L-aspartic acid and L-leucine were the major free amino acids. Hardness, springiness, cohesiveness, gumminess, chewiness and resilience degree of sponge cake with addition of laver power were higher than those of control. The sensory evaluation indicated that addition of 2% laver powder enhanced most mouth feeling, appearance, hardness, moistness, flavor and overall acceptability.

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.

To make sponge cake using Lentinus edodes powder, which is useful and valuable as a functional food material, we tested samples with 3, 6, 9, and 12% L. edodes powder to ascert200ain the quality characteristic and make optimize preparation. Samples and L. edodes powder-free control sponge cakes were compared in terms of quality characteristics including batter viscosity and specific gravity, moisture content, volume index, weight, color, textural characteristics, and sensory qualities, to determine the optimal ratio of L. edodes powder in the formulation. Viscosity and specific gravity of sample and control batter were not significantly different. Moisture content of the sample and control sponge cake also did not differ significantly, and weight of sample and control sponge cakes did not differ appreciably. The volume index of the samples displayed contrasting values, increasing with 3~6% L. edodes powder and decreasing with 9~12% powder. L, a, and b crust color values of samples sponge cakes were lower than those of control cakes. The L and a values of the control cakes was maximal, with values progressively decreasing with incorporation of more L. edodes powder. The b value decreased by 3% with the addition of up 6% L. edodes powder with no further decrease thereafter. L. edodes powder was the lower value. So was the color a, and L. edodes powder increased, a-values decreased. 3% difference was shown in b, the color and none between the samples with 6~12%. L. edodes powder showed lower values making a comparison with the control. Hardness and fracturablility were not appreciably affected by 3% L. edodes powder, but was affected by concentrations 6%. Fracturability og sample sponge cakes was consistently lower than control cakes. Fracturability made little difference in 3% samples, but it was not the same with more than 6% L. edodes powder samples; the samples showed lower value than the control. Adhesiveness was not significantly affected. Chewiness was lower in all sample cakes except those prepared with 3% L. edodes powder. Use of L. edodes powder conferreds higher resilience values as compared to thecontrols. Sensory attributes of color, flavor, softness and overall acceptability were the highest in control sponge cakes, as the amount of L. edodes powder increased, the acceptability decreased. L. edodes-flavor, pleasant taste and off-flavor were the lowest in control cakes, and values increased as the amount of L. edodes powder increased. The control sponge cakes showed the highest values in egg-flavor and moistness, which progressively increased as added L. edodes powder increased. The results indicate that control sponge cakes displayed were. the highest overall acceptability, with acceptability decreasing and it decreased as L. edodes powder content increased. However, 3~6% L. edodes powder can produce an acceptable product, and may be used as anoptimized mixture ratio.
