To investigate the relationship of wheat single kernel characteristics with end-use properties, 183 soft wheat cultivars and lines were evaluated for milling quality characteristics (kernel hardness, kernel and flour protein, flour ash), and end-use properties (i.e., as ingredients in sugar-snap cookies, sponge cake). Significant positive correlations occurred among wheat hardness parameters including near-infrared reflectance (NIR) score and single kernel characterization system (SKCS). The SKCS characteristics were also significantly correlated with conventional wheat quality parameters such as kernel size, wheat protein content, and straight-grade flour yield. The cookie diameter and cake volume were negatively correlated with NIR and SKCS hardness, and there was an inverse relationship between flour protein contents and kernel weights or sizes. Sugar-snap cookie diameter was positively correlated with sponge cake volume.

The purpose of this study was to examine the quality variations of cake and cake batter when either butter or soybean oil was added in plain sponge cake batter. Soybean oil or butter was added to the batter at ratios of 20, 40, and 60% at 20, 35, 60, and $80^{\circ}C$. The physico-chemical properties of cake batter and cake were measured to evaluate the effects of ratio and temperature of butter and soybean oil. At higher ratios of butter or soybean oil and lower temperatures, the specific gravity of the cake batter increased while the interrelations among weight, volume, and specific loaf volume decreased. L- and b- values were the same, but a-value increased remarkably with higher ratios of butter. The effect of adding butter or soybean oil on hardness was shown to be lowest at 40% and $80^{\circ}C$. Baking loss in the baking process with soybean oil decreased with increasing oil quantity and temperature. Moisture content did not change with temperature, but did decline with increasing amounts of butter or soybean oil. These results show that the optimum condition for sponge cake would be 40% soybean oil at $80^{\circ}C$.

This study was performed in order to investigate the quality characteristics of sponge cake made with Laminaria japonia powder. To evaluate the physical and sensory analysis, Laminaria japonia powder was added to wheat flour in various ratio (3, 5, 7, 9%, w/w). The specific gravity and loss rate increased with the addition of Laminaria japonia powder. The crude protein and ash levels in the sponge cakes increased linearly with the addition of 0~9 g of Laminaria japonia powder/100 g of wheat flour. For the crumb color values, lightness (L) and yellowness (b) decreased with the addition of Laminaria japonia powder, whereas redness (a) significantly increased (P<0.05). In the texture analysis, the hardness, gumminess and chewiness were increased; however, the cohesiveness and resilience were reduced by the addition of Laminaria japonia powder. When the sensory characteristics were evaluated, 5% Laminaria japonia sponge cake showed the highest sensory properties, except for color. Therefore, the results suggested that 5% Laminaria japonia sponge cake could be helpful in improving the physical quality as well as the taste.

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.

This experiment was carried out in order to investigate effect of rice varieties, milling methods and particle sizes of rice flours on characters of songe cake. The expansion height of batters peaked from in 14 to 18 minutes during baking for 34 minutes at $150^{\circ}C$, and then was gradually decreased. The decrease in the height ranged from 6 to 50% compared to the expansion peak of batters at one day after baking. The inner temperature of the batters showed a tendency to increase slowly and was greatly increased for 8 to 10 minutes. The highest temperature was 94 to $96^{\circ}C$ in 24 to 26 minutes during baking. The volume of the rice cake was not affected by the particle sizes of the rice flours and milling treatment, and ranged from 89 to 95% compared the volume of wheat cake. Therefore, this result indicated the great possibility baking sponge cake used with rice flours. The baked sponge cake by the hydrated flours showed lower stregth than that by the non-hydrated rice flours without correlation with kinds and particle sizes of rice flours, and there were not significant differences in the cohesiveneness of the cakes. The sponge cake of the hydrated rice flour of Taebaek variety was generally superior in texture and taste to the cake of wheat flour as the result of sensory evaluation.

The characteristics of sponge cakes prepared from various formulas having different types and levels of fat were examined through physical measurements and sensory evaluation. The physical properties of cake batters and cakes with hicook, that is, specific gravity and mixing characteristics of cake batters and volume of cakes, were similar to cakes with oil and added lecithin as emulsifier. Also in sensory evaluation the uniformity of air cell and moistness of cakes showed no significant differences in these samples. From this result, we concluded that lecithin is responsible for the characteristics of cakes with hicook. And hicook successfully replaced soybean oil in sponge cakes, and the fat content of cakes with hicook colud be reduced by 20％ relative to cakes with soybean oils.

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.
