Eight Korean wheat cultivars were milled and evaluated for the properties of white layer cake-making, compared to a commercial soft wheat flour. Milling yields of the Korean wheat cultivars ranged from 62.5 to 71.8%. The protein and ash contents of flours milled from Korean wheat cultivars ranged from 7.70 to 10.58% and 0.51 to 0.71%, respectively. Woorimil, Alchanmil and Olgeurumil flours, having low protein content, showed very weak mixing characteristics. Even though Eunpamil and Geurumil flours showed longer mixing time and higher peak height, they had week dough stability. Slight differences in pH and specific gravity of cake batter were observed among the Korean wheat flours. Cake volume measured by rapeseed displacement was in the range of $837.5{\sim}952.5\;cc$. Alchanmil flour demonstrated the highest specific volume of 2.40, and the other domestic flours symmetrical and uniform than those with the commercial soft wheat flour. Volume of white layer cakes was negatively affected by flour protein content and somewhat associated with crumb softness. Crumb color of cakes prepared with domestic wheat flours was slightly darker and more yellowish. Hardness of fresh cakes prepared with domestic flours ranged from 307.33 to 416.60 $g_f$.

This study was conducted to evaluate the baking characteristics of yellow layer cake containing chlorella powder. Chlorella at concentrations of 0, 4, 8, 12, and 16%(w/w) wheat powder were added, after which we evaluated the baking characteristics, physical properties, and sensory properties of the resulting cakes. Regarding the weight and volume of the cakes, the treatment groups were similar. However, control showed a high hardness value while 16% chlorella added cake showed a significantly low value. The 4% and 8% chlorella added groups maintained their structural condition while the 12% and 16% chlorella added groups were softer depending on the protein content of the flour, Lightness(L value) and yellowness(b value) of the cake crumbs became lower depending on the concentration of chlorella, whereas redness(a value) decreased. In the sensory test, the acceptability scores of the 12% and 16% chlorella added groups were lower compared to control while the 4% and 8% chlorella added groups had higher scores. Therefore, chlorella powder added yellow layer cake exhibited more functionality as well as higher quality.

This study was conducted in order to investigate the effects of maesil extract on medium and cake flour using the falling number and RVA tests, as well as farinography, and alveography. The maesil extract were added on the medium and cake flour bases, 3% and 5% each. The falling numbers of the medium and cake flour with maesil extract were increased due to alteration of the protein in the flour. Analysis of the RVA characteristics showed that the addition of maesil extract did not have a significant effect on the initial pasting temperature. Peak viscosity, holding strength, final viscosity, and the breakdown and setback values of the medium flour were not consistent, but those of the cake flour decreased. Farinography demonstrated that the addition of maesil extract decreased water absorption and improved the stability of the medium and cake flour. The characteristics of the alveogram showed that the addition of maesil extract increased the extensibility and swelling index. Based on the experimental data, the processing rheology may be good when using maesil extract to make yellow layer cake.

This study was carried out to investigate the quality characteristics of yellow layer cake mulberry powder. After making yellow layer cake with mulberry powder, water activity, crumb texture, crumb color, and sensory tests were investigated. After 1 day of storage, Aw of control with weak flour did not show any significant difference, whereas those with 1, 3. 5% mulberry powder showed a significant decrease in Aw. During storage, the Aw values of yellow layer cakes containing mulberry powder were consistent. Hardness, springiness, cohesiveness, and gumminess of the yellow layer cakes containing mulberry powder all decreased compared to those of control. Hardness, springiness, cohesiveness, and gumminess all increased with storage time. Further a higher percentage of mulberry powder was associated with a lower L value, but higher a value. b values were lower in the 1% and 3% mulberry powders, but 5% showed a slightly higher b value. An increase in storage time was associated with decreased L and b values and increased a value. The micrographs of yellow layer cakes with mulberry powder showed a slightly coarser porosity than that of controls. The results of the sensory test showed that the over-all acceptability of 1% mulberry powder cake was the best.

The protein contents of soy protein isolate (SPI) and soft wheat flours were 83.5% and 8.5%, respectively. The addition of SPI increased the protein content but decreased the sedimentation value. Alkaline water retention capacity (AWRC) value increased with SPI addition and was highly correlated with protein content. Increasing SPI flour content significantly decreased the maximum, minimum and final viscosities. Mixograph peak time was positively correlated with protein content and AWRC. The PH and specific gravity of the cake batter increased with increasing SPI content. The SPI addition reduced the loaf and specific loaf volume compared with soft wheat flour. The lightness of the cake crust decreased, while the redness and yellowness increased, with SPI flour addition. SPI addition resulted in a decrease of overall acceptability, but an increase in hardness.

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.

We researched the physical, chemical, functional, textural, and manufacturing characteristics of yellow layer cake which prepared by adding different amounts of persimmon leaf powder (0, 4, 8, 12, 16%). The color of the crumbs inside the cake appeared dark, demonstrating that the L value decreased as the amount of persimmon leaf powder increased. The value of a, which corresponds to the level of redness, increased and the cake appeared dark red as the amount of persimmon leaf powder added increased; whereas, the yellowness of the cake tended to decrease as the value of b, which corresponds to the level of yellowness, gradually. As the amount of persimmon leaf powder added increased, the specific loaf volume of the cake increased, but the amount of baking loss tended to be similar at all. The textural characteristics of hardness and gumminess tended to increase, but cohesion and elasticity were not influenced by the addition of persimmon leaf powder. In the sensory test, color was rated low, but flavor, taste, and texture showed the highest score in 8% as the amount of persimmon leaf powder added increased. The general preference was highest when the persimmon leaf powder was added in the amount of 8%, and it decreased as the amount of persimmon leaf powder added increased.

The purpose of this study was to improve the quality of yellow layer cake by adding the Adenophora remotiflora powder. The effects of the Adenophora remotiflora powder in on the final product quality of yellow layer cake and the optimum amount of the Adenophora remotiflora powder in the yellow layer cake formula were investigated. The more increased amounts of Adenophora remotiflora powder was added to the samples, the resulted in "L", and Hunter's "a" and "b" values of the crust color of yellow layer cake were significantly decreased (p<0.05). In the case of crumb color, the more increased levels of Adenophora remotiflora powder led to the samples, the "L" and "a" values were significantly decreased (p<0.05), but "b" value increased significantly (p<0.05). As more Adenophora remotiflora powder was added to the cake samples, the Hardness, Gumminess and Chewiness were significantly increased (p<0.05), but Springiness and Cohesiveness were did not. The results of sensory evaluation showed revealed that the addition of 2% of Adenophora remotiflora powder of overall acceptability were most preferred. Larger scanning electron microscopy revealed the presence of numbers of greater concentrations of cells with different sizes were observed for in samples from products that received 1 % Adenophora remotiflora powder addition. Collapsed cells and cell coalescence with big large and irregular shapes were shown observed in samples that were amended with at 2, 4, and 8% addition Adenophora remotiflora power. The addition of Adenophora remotiflora powder was shown to improved the functionality and quality characteristics such as color, taste and flavor of yellow layer cake. Therefore, it was expected that the 2% addition of Adenophora remotiflora powder will improve the preference to the yellow layer cake.
