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.

This study examined the optimal ingredient mixing ratio for the preparation of steamed cake containing mugwort (Artemisia princeps var. orientalis) powder. After preliminary studies, the following ingredient ranges were determined; 110~129% sugar, 3~8% mugwort powder, 10~25% oil. Among the different mixture designs, the D-optimal design was chosen for analysis. The results of F-test, specific gravity, viscosity, volume and color values (L, a, b), hardness decided a linear model, while the sensory characteristics (color, taste, texture and overall acceptance) decided a quadratic model. The fitness analysis results showed that in all characteristic, the probabilities were significant within 0.05%; thus, the models were accepted as appropriate. The response surface and trace plot results showed that increasing amounts of mugwort powder decreased the brightness, and increased redness and yellowness. As the level of added oil increased, the softness of the cake increased. Cake samples received low sensory evaluation scores when sugar, mugwort powder, and oil were added above their optimal levels. The optimum formulations by the numerical and graphical methods, were similar, and with the numerical method presented as: sugar, mugwort powder, and oil at 120.7%, 5.1%, and 16.2%, respectively(flour weight basis). The above results demonstrate the feasibility of adding mugwort powder to sponge cake, and therefore, the commercialization of mugwort powder cake marketed as a functional food is deemed possible.

This study was investigated the quality characteristics of sponge cakes which were prepared b replacing 30% of flour with raw starch and resistant starches, such as, 4 cycled autoclaved-cooled RS 3 maize starch(RS 3), cross-linked RS 4 maize starch (RS 4) was superior to control cake( 100% flour cake). Addition of starches except RS 3 made crust and crumb color lighter and decreased hardness. Especially, cake containing RS 4 had the softest texture. For the adhesiveness and cohesiveness, cake containing RS 4 showed the least changes during 5 storage days. In DSC measurement, cakes containing RS 4 and ARS 4 showed high enthalpy in despite of low hardness. Sensory evaluation showed that cakes containing RS 4 and ARS 4 were significantly moist and soft compared to others. Overall acceptability of cakes containing starch, RS 4 and ARS 4 were evaluated excellent. Therefore, it can be suggested that RS 4 and ARS 4 can be added to the sponge cake for the quality improvement and functional element.

Black tea is rich in phenolic antioxidants that has shown diverse health benefits such as protection against cardiovascular diseases and cancers. Thus, it is rational to incorporate black tea into suitable food products such as sponge cakes to enhance their nutritional and functional qualities. The aim of this study was to investigate the effect of the addition of black tea powder (BTP) on the quality of sponge cake. The pH of cakes ranged from 7.00~7.17, with no remarkable differences. Height decreased while baking loss rate and hardness significantly increased with increases in the content of BTP in the formulation (p<0.05). For crumb color values, $L^*-value$ decreased while $a^*$ and $b^*-values$ increased as a result of BTP substitution. 2,2-Diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis-3-ethylbenzthiazoline-6-sulphonic acid (ABTS) radical scavenging activities were significantly increased (p<0.05) with increases in the content of BTP which were well correlated. Hedonic sensory results indicated that sponge cakes supplemented with 2~4% BTP obtained the most favorable acceptance scores. On the basis of the overall observations, sponge cakes supplemented with 2~4% BTP were found to be benefit from the functional properties of BTP, without compromising on consumer acceptance.

This study investigated the quality characteristics of butter sponge cakes added with whey protein concentrate (WPC)(0%, 10%, 30%, 50%, 100%) added as a fat substitute. The density of the dough of butter sponge cakes significantly increased with higher levels of added WPC and the pH decreased (F=248.38, p<.001). The moisture content also decreased significantly (F=3.151, p < .05). However, the volume (F=9.556, p<.01) and specific volume (F=11.15, p<.001) significantly increased. With respect to color, there was no significant difference in the lightness (L) value of the crumb, but the redness (a) value increased significantly with higher levels of added WPC (F=12.616, p < .001), while the yellowness (b) value decreased significantly (F=4.550, p<.01). Regarding the crust, the L values (F=3.791, p<.01) and b values (F=7.000, p<.001) decreased significantly with higher levels of added WPC, while the (a) values increased significantly (F=4.706, p<.01). The DPPH radical scavenging ability of the raw WPC used in the manufacture of butter sponge cakes was found to be 27.45%, but this increased significantly as the amount of WPC added to butter sponge cakes increased (F=45.237, p<.001). In a consumer preference test, the flavor, appearance, texture, odor, and overall acceptability were highest in the case of WPC-10 when taking advantage of the functional advantages of WPC as a lowfat substitute, confirming the development potential and optimal amount of WPC that should be added to butter sponge cakes.

This study investigated the quality characteristics of sponge cakes with addition of corn starch. The corn starch was added with 0 (control), 10, 20, 30, and $40\%$ substitution ratios by weight per wheat flour, followed by measuring physical and sensory characteristics of product during storage Periods. Batter specific gravity decreased with increasing substitution levels while viscosity increased. The volume tended to increase according to the addition of corn starch. As storage progresses, hardness and chewiness increased in all treatments. $30\%$ treatments showed lower values, compared to other treatments throughout the storage period. Adhesivness increased as the amount of corn starch increased. The results of sensory evaluation showed that the overall acceptability of sponge cakes containing $20\%\;and\;30\%$ corn starch were higher than that of control without corn starch. Therefore, it can be suggested that of corn starch $30\%$ added to tile sponge cake for the quality improvement and functional element.

The effect of baking on the physicochemical and sensory properties was investigated using a model system of sponge cakes incorporated with pine leaf powder (PLP) as a value-added food ingredient. PLP was incorporated into cake batter at 5 levels (0, 2, 4, 6, and 8%, w/w) by adding an equivalent amount based on the weight of wheat flour. After appropriate mixing, sponge cakes were baked at $170^{\circ}C$ for 30 min in an oven. The baked cakes were cooled to room temperature for 1 h prior to all measurements. The pH, moisture content, specific volume, height, volume index, and symmetry index decreased significantly with the increase in PLP content (p<0.05). On the contrary, specific gravity of the batter and baking loss increased (p<0.05). The lightness of the cakes decreased, whereas redness increased significantly with the higher amount of PLP in the formulation (p<0.05). Hardness also increased significantly (p<0.05). Both total polyphenol content and DPPH (1,1-diphenyl-2-picryl hydrazyl) radical scavenging activity increased significantly by the addition of PLP (p<0.05). The consumer acceptance test indicated that the addition of PLP up to 4% did not cause a significant unfavorable effect on the consumer acceptances in all attributes. The sponge cakes with 2-4% PLP would be recommended with respect to the overall acceptance score while taking advantage of the functional properties of PLP without sacrificing the consumer acceptability.

The functional Jeungpyuns with dietary fiber containing cereals such as brown rice and barley flour were developed and physiochemical properties were investigated. The water binding capacity had significantly the highest value of 28.4% in raw rice flour, followed by brown rice flour and barley flour. The lowest reducing sugar value was seen in unpolished rice substituted Jeungpyun with value of 5.420 (P<0.05). The amount of reducing sugar decreased slightly after steaming, due to the increased degree of sugar dissociation. The L value of the lightness decreased significantly with the substituted samples (P< 0.05). The barley substituted samples were darker than that of brown rice sample groups with less green and yellow color. Microstructures of starch particles after fermentation showed completely dispersed starch particles with air bubbles and sponge-like structure in all samples after steaming. Thus, functional Jeungpyun replaced with brown rice and barley flour can be successfully formulated and has been influenced by the physicochemical properties.

The feasibility of incorporating cinnamon as a value-added food ingredient in bakery food products was investigated using sponge cakes as a model system. Cinnamon powder was incorporated into sponge cakes at 0, 1, 2, 3, or 4% weight amounts, based on the total weight of wheat flour. Cake qualities, such as pH, moisture content, specific volume, and baking loss, decreased significantly with increasing levels of cinnamon powder added (p<0.05). In terms of color, lightness and yellowness decreased, with increasing levels of cinnamon powder. Redness significantly increased for crumb, but decreased for crust (p<0.05) with increasing levels of cinnamon powder. Hardness also significantly increased (p<0.05), while total polyphenol content significantly increased, up to a 2% addition of cinnamon powder, and gradually increased afterwards. Finally, the consumer acceptance test has indicated that higher levels of cinnamon incorporation (2% or higher, w/w) have a considerable adverse effect on consumer preferences in all attributes. In contrast, sponges cakes with a minimal level of cinnamon powder (1%, w/w) are recommended for taking advantage of the functional properties of cinnamon powder without sacrificing consumer acceptability.
