Rice cake is the most historical food which has been developed from settlement of agriculture and typical traditional food which has manufacture and food historical meaning. Because, the process of rice flour, raw ingredient of rice cake, tells remarkable food processing technology of our nation, and is original form of processed food that we has been taken before agricultural life begun. In this study, contents analysis method is used. Ingredients of rice cakes appeared in "Gyuhapchongseo" glutinous rice 12 times (42.8%), nonglutinous rice 10 times (35.7%), and the others 6 times (21.4%) used as the main ingredients of rice cake. the rice cake separated into 15 types (53.5%) of steamed rice cake, 2 types (7.1%) of pounded rice cake, 3 types (10.7%) of boiled rice cake, 7 types (25%) of sauteed rice cake, and 1 types (3.5%) of the others. it become data for knowing social and dietary culture of the time. And it is for presenting fundamental material of possibility of modern rice cake.
The objective of this study was to seek the best recipe for making Gamdanja. Gamdanja is a kind of rice cake made from persimmon extract and winy flour, with a little salt mixed into the waxy flour. The method involved boiling the persimmon extract and beating in the waxy rice powder until all the waxy flour had been added. The procedure was as follows: Gamdanja containing different ratios of ingredients, such as persimmon extract (23, 23.5 and 24 hrs) and waxy rice flour (160 and 180g). The most desirable recipe was determined after sensory examination and mechanical tests using texture, moisture content and colorimeter measurements. The results of the sensory evaluation showed that Gamdanja made using persimmon extracted for 23.5 hrs, with the additional of 160g of winy flour gave the higher scores for QDA profile, chewiness, delicacy and after swallowing preference than the other ratios. The results of the acceptance test also showed that the Gamdanja made using the persimmon extracted for 23.5 hrs with 160g of waxy rice flour was the best mix in every respect, such as for color and overall acceptability. In the textural analysis of Gamdanja, the hardness, adhesiveness, gumminess and chewiness were increased by the additiong of furtherway lour. The moisture content of Gamdnja with persimmon extracted for 23 hrs was higher an those extracted for 23.5 and 24 hrs. The L-, a- and values of Gamdanja were increased with decreasing waxy flour. The sensory and mechanical examinations showed the overall quality of Gamdanja had positive correlations with delicacy and color, but negative correlations with hardness, adhesiveness, gumminess, and chewiness. As a result of these tests, the most desirable recipe for the Gamdanja was persimmon extracted for 23.5 hrs with the additional of 160g of waxy rice flour, containing $1\%$ salt and a moisture content of $45.87\%$.

Effect of various ingredients and cooling methods on the quality of modified Jeung-pyun(traditional Korean steamed rice cake) were studied. Three different kinds of wheat flours(strong, medium, and weak) were studied to evaluate the volume and firmness of Jeung-pyun. Weak flour showed the maximum volume and good sensory results. The optimum ratio of ingredients was flour : water ; sugar ; Tak-Ju=100 : 20 : 20 : 50 for steaned Jeung-pyun. When three different cooking methods were compared, the maximum volume showed from convection oven method, but the crust color of Jeung-pyun was like bread. Steaming method showed higher volume than that of product heated by microwave method. The optimum formula ratio for the microwave method was flour ; water ; sugar ; Tak-Ju = 100 : 30 : 20 : 50, which required 10% higher added water content than that of steaming. When wheat flour was used instead of rice flour, the addition of 5% normal corn starch increased volume of both steamed and microwave cooked products. In the case of added modified starches to Jeung-pyn, 5% $\alpha$-waxy corn starch showed the highest volume in steaming method. When rice flour was used, the addition of 5%$\alpha$-waxy corn starch also showed highest volume f both steamed and microwave cooked products. The firmness of steamed wheat flour Jeung-pyun, containing 5%$\alpha$-corn starch was higher firmness than that of control and other added samples. Microwave cooked products showed two or three times higher firmness of steaming products. The use of wrap(uni-wrap) and stabilizer(METHOCEL) decreased the firmness of microwave cooked wheat flour Jeung-pyun to 200~300g compared with that of untreated Jeung-pyun.
The quality characteristics and processing of rice cake (Backsulgi) with rice flour containing Lactobacillus plantarum CGKW3 by spray-drying (LP-B) were investigated. The LP-B was applied at ratios of 10, 20, and 30 (w/w), and the moisture contents and pH were 33.39%~36.70% and 5.81~5.46, respectively. The L value of LP-B increased as the rice flour decreased, while the a and b value increased as the LP-B increased. The texture profiles showed that Backsulgi prepared with LP-B mixture had higher hardness, cohesiveness, springiness and chewiness than 100% rice flour. The pH of LP-B Backsulgi (LP-B20 and LP-B30) did not differ during 6 days at room temperature. The total bacteria in Backsulgi prepared LP-B20 and LP-B30 Backsulgi was $10^4CFU/g$ after 2 days of storage at room temperature. The shelf life of Backsulgi prepared with LP-B20 and LP-B30 were extended by about 2 days when compared with the control at room temperature. Sensory evaluation showed that Backsulgi without LP-B20 had higher scores in terms of appearance, color, flavor, taste, texture, hardness and overall acceptability than Backsulgi without 100% rice flour. In conclusion, the results demonstrate that LP-B20 may prove quite useful as a Backsulgi flour with desirable properties.

This study attempts to analyze the physicochemical characteristics of rice flour developed as rice powder for exclusive use, steamed rice cake recipes developed as basic recipefor rice cakes. The study also aims to compare the quality characteristics of steamed rice cakes in an effort to establish the possibilities of developing various rice cake recipes. The moisture content and amylose content increased as the rice powder particles for exclusive use became finer. With regards to water uptake, in the case of the Hungara type, the water uptake increased as rice powder particles increased in size. In the case of the Shingil and commercial types, the water uptake decreased as rice powder particles increased in size, and solubility and swelling force decreased as rice powder particles increased in size. In the case of chromaticity, Sulgidduk made with rice powder for exclusive use the brightness (L value) increased as powder particles became finer and the yellow indexes (b value) decreased, and this was especially pronounced in the Shingil type. The measurements of changes in the mechanical textures of Sulgidduk showed that rice types with larger particles led to lower hardness, cohesiveness, springiness, and chewiness.
Yackwa is a Korean traditional fried cake made by went flour, sesame oil and honey. This study was investigated to the Rice-Yackwa for the purpose of the improvement of Yackwa's quality and rice consumption by sensory evaluation and instrumental measurement. It was resulted that taste and flavor of Rice-Yackwas were better than those of Wheat-Yackwa by sensory evaluation. We tested whether the mesh of the rice (80,100,120) and swelling agents (baking power, soju : Korean alcholic beverage) affected the Rice-Yackwa's swelling or not. In result, not by soju but by baking powder Rice-Yackwas were swelled. But Rice-Yackwa was so hard, that the Yackwas were made by the two different compositions of mixed flour (rice : wheat ; 75:25, 50:50) exibited softer than those made by rice. The hardness of 25 g% mixed flour Yackwa was improved. And we examined the softening effect on rice and mixed flour Yackwa by the increasing storage periods (1, 2, 3, 5 days). Rice-Yackwa's hardness was changed more greatly than Wheat-Yackwa's by storage periods. In addition to we inspected the effluence of sesame oil in the pross of frying. Sesame oil (40%) was drown out the Rice-Yackwa.
This study was carried out to understand and analyze the cooking and processing methods presented in CHE MIN YO SUL (chapter 82~86). The result from the study are as follows; 1. Byung was made from dough of wheat flour, glutinous rice flour, small green peas flour an rice of millet etc. by steaming, roasting, deep fat frying or sauted, or it had eaten Byung which was made from egg or seagull's egg without cereal was simillar to Korea's fried egg cake. 2. Jong and Youl were steamed product made from mixture of millet and rice which were wrapped with leaf of Julpool or bamboo's leaf. It's shape was simillar to Korea's Song-Pyun but different from materials and cooking method. 3. Jamyong's cooking method was boild the mixture of white rice soup, Myong-Jup, and salt. and then pour the rised Bal. 4. Ye and Lo were boiling product made from new oat and appricot seed flour. It was simillar to sweet drink made from rice, and put them in the jar for storage.
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 study investigated the quality of pound cake added with various concentrations of perilla leaves (Perilla frutescens var. japonica HARA) powder. Pound cake were prepared by addition of 0, 5, 10 and 15% powder to the flour of basic formulation. The pH of the batter and cake decreased with increasing perilla leaves powder concentration. The baking loss rate of the pound cake tended to increase by 7.13~7.42%. The height of pound cake added with perilla leaves powder decreased with increasing powder concentration. The lightness, redness, and yellowness values were significantly decreased with increases in perilla leaves powder except for redness of pound cake crumb. The pound cakes containing 5% perilla leaves powder had acceptable sensory evaluation, such as flavor, taste, moistureness, and overall preference. The hardness and gumminess tended to increase, while springiness and cohesiveness decreased with increases in perilla leaves powder. The retrogradation degree of pound cake prepared with perilla leaves powder for 7 days at $25^{\circ}C$ was higher than the control but there were no significant differences. For the antioxidative activity measured by DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging activity, pound cake added with 10% and 15% added perilla leaves powder showed high antioxidant activities. The results exhibited that adding the perilla leaves powder into the pound cake increased antioxidant activity with the highest quality improvement obtained by incorporating 5% (w/w) of perilla leaves powder into the pound cake formula.
This research investigated the consumption of various rice-based processed foods of 279 housewives in Daegu. 70% of the housewives that responded to the question graduated from a high school or college, was 30∼40 years old and full-time housewives. The main places for purchasing the rice-based processed foods were large size discount store and supermarkets, as other industrial products and the family′s preference was the most critical factors in choosing the products. The fact that the main reason of purchasing the rice breads and cookies, instead of wheat, was "They may be good for health” indicated many housewives have a positive perception of rice-based foods. Among the rice-based processed foods, the using frequency of rice cake (dduk) was the highest, with rice cookies and rice drinks being the next most frequent. However, the frequencies of cooked rice (bob) and rice flour were very low. An analysis of the correlation for the using frequency of 15 rice-based processed foods showed that the use of rice cookies and breads, instead of wheat, was highly correlated to another 13 foods. The critical reasons why they do not consume cooked rice and rice flour were uncertainty of the purity of the rice and the addition of preservatives, and that with rice bread and noodles there was no information available about the products, and hey have a poor taste. The most common reasons of using cooked rice were no time to cook and simple curiosity about the products. However, the consumers were suspicious of containers, which were a potential cause of environmental hormones, and the high price of the products. Packed rice flour was mainly used as an ingredient to give the viscosity to a product. The advantages of using rice flour were that it was available to control the amount of buying and the convenience to buy. However, it was pointed out that the taste of products containing packed rice flour were poorer than that of rice flour ground at a mill.
