In this study, rice flour sponge cakes were prepared by replacing 50% of the sucrose with oligosaccharides. Isomaltooligosaccharide and fructooligosaccharide were used as the oligosaccharides. The effects of oligosaccharides on the physical, textural and sensory properties of the cakes were then examined. The oligosaccharides increased batter viscosity and decreased batter specific gravity and baking loss. The moisture content, specific loaf volume and loaf volume index of the cake increased by replacing 50% of the sucrose with oligosaccharides. Internal and exterior color determinations showed that the 'L' value of the sponge cake with oligosaccharides was lower than that of the control, indicating a darker crust and crumb with the oligosaccharide substitution. Decreases in textual hardness, chewiness, and brittleness occurred with the oligosaccharides. Sensory panels perceived that the oilgosaccharide darkened the crust of the rice flour sponge cake and the panelists rated the cakes with the oilgosaccharide substitutions as sweeter, softer and more moist. The rice flour sponge cakes with isomaltooligosaccharides had a significantly higher acceptability then the others.

This study was conducted to compare the quality of steamed cakes supplemented with common buckwheat(F. esculentum Miench.) and tartary buckwheat(F. tartaricum Gaetn). A proximate analysis, and rutin content, color value, texture characteristics and sensory evaluations were performed, In the proximate analysis, the steamed buckwheat as opposed to raw buckwheat, appeared to afford higher values for most of the evaluated items. The rutin content of the tartary buckwheat was over 14 times higher than that of common buckwheat and remained about 58% higher after steaming. The lightness of the steamed cakes was in the following order: control(wheat flour only), with the addition of common buckwheat, and with the addition of tartary buckwheat. The redness and yellowness increased in the following order: tartary buckwheat, common buckwheat, control steamed cake. There were no significant differences in the springiness of steamed cake between the various samples including the control: therefore, resulted in good quality during bread-making. In the sensory evaluation, on increasing the amount of tartary buckwheat addition the score for entire taste increased compared with common buckwheat and the control and also had positive results for all other items, including flavor, color, softness and moistness. This study has suggested the ability to make steamed cakes containing tartary buckwheat flour.

This study was conducted to investigate the effects of garlic powder on medium and cake flours using falling number and RVA tests, as well as alveograms and farinograms. The garlic powder was added to the medium and cake flour bases at 2 and 4%, respectively. Falling numbers increased with the addition of garlic powder. The peak viscosity of the medium flour containing 2% garlic powder was highest while that made with 4% garlic powder showed a decrease in peak viscosity. The addition of garlic powder increased the set-back value, thus the garlic powder did not have an anti-retrogradation effect. The alveographic P values of the treatment were lower than that of the control, but the L value was not significantly different. On the farinogram, water absorption was decreased in the flours containing garlic powder and development time was increased. In conclusion, the addition of 2% garlic powder is recommended to improve the volume and stability of cake.

Baked black soybean has great nutritional value, so it is a great potential ingredient in cake. To find an acceptable ingredient ratio, baked black soybean powder was to wheat flour in different experimental groups. The control was pure wheat flour, and the experimental groups had 0 (control), 10%, 20%, 30%, and 40% baked black soybean powder added. The baked black soybean powder consists of moisture (4.88%), crude protein (34.46%), crude fat (11.35%), crude ash (4.84%), and carbohydrates (44.47%). The specific gravity, spreadability, and baking loss increased with an increase in the amount of baked black soybean powder, but specific volume decreased. The 'L' and 'b' chromaticity values of a sponge cake decrease with increased amounts of added baked black soybean powder. The texture becomes more hard and stuff with added baked black soybean powder, but springiness decreases. A sensory test found the best experimental group to be that of 20% powder added.

The texture and descriptive sensory characteristics of a Korean rice cake(Karedduk) with added emulsifier were investigated after 2 and 24 hrs of storage at $5^{\circ}C$. The emulsifier, SP, was added at 0, 0.1, 0.5 and 1% levels to the dry rice flour. In the amylogram, the peak viscosity(P), hot paste viscosity(H) and cold paste viscosity(C) of the rice flour with added emulsifier were higher than those of the control. The texture property analysis by a Texture Analyzer revealed that the springiness, cohesiveness and adhesiveness of the Korean rice cake(Karedduk) with added emulsifier were similar to those of the control, while chewiness, gumminess and hardness were lower compared to the control. Also, the hardness by sensory characteristics was significantly different as compared to the control. Lastly, adding emulsifier to the Korean rice cake(Karedduk) was effective at retarding retrogradation.

The purpose of this study was to select an ingredient acting as a natural emulsifier to retard the retrogradation of rice cake by the measurement of mechanical characteristics of the cakes. For the purpose, Backsulgi, the most basic type of rice cake, was prepared by adding various ingredients having high contents of lecithin such as raw soybean powder, parched soybean powder, soybean oil, egg yolk powder, and the measurements and observations on the chromaticity, swelling power, pore ratio and cross-section were made. In addition, changes in the textural characteristics of Backsulgi samples were determined while storing them at the temperatures of 4$^{\circ}C$ and 20$^{\circ}C$ for 0, 1, 2 and 3 days. The results of the study were as follows: 1. In terms of chromaticity, the Backsulgi samples added with egg yolk powder, raw soybean flour and parched soybean flour were higher in yellowness(b) than the controls. 2. Both swelling power and pore ratio of Backsulgies added with raw soybean flour were higher than those of controls. 3. A cross-sectional observation using an electron microscope indicated that rice flour particles of controls had uneven pores and were conglomerated in a large lump while Backsulgi samples of raw soybean flour or roasted soybean flour had large and even pores and showed loosened bonding to be transformed into a sponge shape. 4. In hardness, Backsulgi samples added with raw soybean flour had less changes in hardness than that of controls, indicating that the effect of retarding retrogradation was higher when the storage time got longer.

This study carried out to investigate the effects of yacon powder on yellow layer cake made with weak flour. After making yellow layer cake with yacon powder, water activity, crumb texture, crumb color, and sensory characteristics were investigated. After 1 day of storage, Aw value of control cake with weak flour did not show any significant differences, whereas those with 2, 4, and 6% yacon powder showed a significant increase in Aw. During storage, the Aw values of yellow layer cakes containing yacon powder decreased. Hardness and gumminess of yellow layer cakes containing yacon powder decreased compared to those of control, whereas springiness and cohesiveness of yellow layer cakes increased compared to those of control. Hardness, springiness, cohesiveness, and gumminess all increased with storage time. Further a higher percentage of yacon powder was associated with lower L and b values as well as a higher a value. The micrographs of yellow layer cakes with yacon powder showed slightly coarser porosity than that of control. The results of the sensory test showed that the overall acceptability of 2% yacon powder cake was the highest.
