This study was conducted to test the characteristics of dough made with rice flour for preparation of steamed cakes containing rice flour. We used a RVA (Rapid Visco Analyser), farinogram and alveogram to analyze cake flour and mixed powder containing 10, 20, and 30% rice flour for the water activity, texture, and, color changes after different storage periods. We found that rice flour inhibited starch aging, and that gluten free rice flour made the cakes more delicate. However, steamed cakes containing rice flour were harder than wheat cakes during storage. Because the cake was steamed, it had more moisture and was softer than cakes baked in an oven. The steamed cake prepared with rice flour became brighter than the control. The results of the consumer acceptance test and sensory characteristics showed that the steamed cake containing 20% rice flour obtained the highest score, indicating that this is the most appropriate level for making steamed cakes.

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.

The results of testing general components, physical property and physical function after having made steamed rice cake by adding eggplant, which caters to consumers' tastes are as follows. It showed that when eggplant powder content increased, the moisture content of steamed rice cake with eggplant was decreased. It also showed that the lightness value (L) of steamed rice cake with eggplant powder was the highest as 82.75 in the control group. When eggplant powder content increased, the redness (a) and yellowness (b) were increased. From the results of having measured the antioxidant potential over the steamed rice cake with freezing-drying eggplant powder by DPPH radical elimination, we figured out that it was the lowest as 48.30% in the control group. As more eggplant powder was added, its elimination increased accordingly. As per hardness of steamed rice cake with eggplant, the added group with 7% was revealed as the highest at 0.757. It showed that adhesiveness was the lowest as 30.233 in the control group, and springiness and cohesiveness were on the rise as freezing-drying eggplant powder was increased. Furthermore, softness and chewiness were shown to be high in the added group with eggplant powder of 3, 5%. The evaluation over the overall preference was the highest in 5% added group. Judging from this, adding 3~5% eggplant powder against non-glutinous rice powder is considered an optimal quantity in making steamed rice cake with eggplant.

In this study we investigated the physical and sensory characteristics of sponge cakes prepared with different levels(0, 2, 4, 6, 8 and 10%) of freeze-dried steamed garlic and Yuza(Citrus junos Sieb ex Tanaka) powder, combined at the same ratio. The cake height and specific loaf volume were highest in the 4% steamed garlic and Yuza powder group. Moisture contents were significantly higher in the 2 and 4% steamed garlic and Yuza powder groups than in the other groups. With increasing steamed garlic and Yuza powder content, the L- and b-values of the crust decreased, but the a-value increased, when compared to the control group. The L-value of the crumb was insignificant within each group. Compared to the a-value of the $0{\sim}2%$ added groups, the a-value of the $4{\sim}10%$ added groups, increased with increasing steamed garlic and Yuza powder contents. However the b-value decreased in the 8 and 10% steamed garlic and Yuza powder groups. The hardness and chewiness of the $6{\sim}10%$ added groups, and the gumminess of the 10% addition group, were significantly higher than in the control group. The results of the sensory evaluation showed there were not significant differences amoung the groups, except for moistness. Therefore, we suggest that the recommended optimal level of steamed garlic and Yuza powder in sponge cake is a 4% addition.

Imwonshibyukji is a copying manuscript written around 1825, the 27th year of king Soonjo of the Chosun Period. It is a massive home encyclopedia of total 52 books and 100 volumes. It was quoted from many Chinese literatures The unpublished 'Jeongjoji'of its 17-20th volumes was analyzed to study the cooking methods on the Korean rice cakes (dduck) and studied for the degree of their usefulness and medical values in the light of the cooking and processing science. The book introduced 6 kinds of Korean rice cake: sirudduck (steamed rice cake), chinundduck (steamed and struck rice cake), zizinundduck (small oil fried rice cake), danggui (steamed rice cake mixed with rice power and honey), hondon (=danja: boiled and stuffed rice cake) and butu (fermented rice cake), all of which were composed of total 64 items. The main materials fur the Korean rice cake were as follows: sirudduck and butu were nonwaxy rice powder, chinundduct dinggui and hondon were glutinous rice powder, and zizinundduck was wheat flour. The side material was mainly natural food with the effect of a medicine. The literatures quoted in Imwonshibyukji are as follows: 4 Korean books including Ongheejabji were quoted total 28 times (41.5%), 5 Chinese books including Junsengpaljeon were quoted total 35times (52.2%), and I Japanese book Whawhansamjedohoi was quoted total 4 times (6.0%). The Korean rice cakes quoted in the Korean literature so far exist but the Chinese ones no longer exist. In the comparative analysis of Imwonshibyukji and other contemporary literatures, Chosunmoossangsinsikyorijebub was the most similar one to the book among others.

The purpose of this study was to improve the quality of the steamed rice cakes added with powder and extract of Schisandra chinensis (SC). Steamed rice cakes were prepared by adding SC using 1% hot-air dried SC powder (DP), hot-air dried SC extract (DE), freeze dried SC powder (FP) and, frozen SC extract (FE). After packaging with nylon/polyethylene films, the cakes were stored at $25^{\circ}C$ for 5 days. The FE-treated steamed rice cake had the lowest pH value. The $L^*$ value of the control cakes was highest immediately after processing and decreased during storage. The $a^*$ values of FP- and FE-treated steamed rice cakes were higher than those of DP- and DE-treated cakes. The $b^*$ values of DP- and DE-treated steamed rice cakes were higher than those of FP- and FE-treated cakes. Total phenolic contents of DP and DE were lower than those of FP and FE. Anthocyanin contents of DP- and DE-treated steamed rice cakes were lower than those of FP- and FE-treated cakes. Schisandrin contents of DP- and FP-treated steamed rice cakes were lower than those of DE- and FE-treated cakes. Ferric reducing antioxidant power assays revealed that DP and DE had lower antioxidant powers than those of FP and FE. The results of this study indicate that, among the treatments methods used, the steamed rice cake treated with FE had the highest functional component and antioxidant activity levels.

Antimicrobial activity of persimmon leaf tea methanol extracts on Klebsiella pneumoniae and Staphylococcus aureus was examined through paper disk diffusion bioassay. K. pneumoniae and S. aureus showed 87.64 and 99.35% growth inhibitions by addition of steamed tea methanol extracts (10 mg/ml), respectively. The number of microorganisms in rice cakes was significantly reduced when leaf tea powder was added during production of rice cakes. Addition of 1% steamed leaf teas to rice cakes decreased the number of microorganisms by over 50%, and over 70% reduction was observed when final 2% (dried weight w/w) steamed leaf tea was added, whereas no significant effect was observed over 2%. These results indicate that different microorganisms were detected from persimmon leaf and rice cake, and persimmon leaf can inhibit normal microbial growth in rice cake.
