  • To make rice cake with squid ink, the squid ink dilulted in fifteen times was added to rice flour in the ratio of 0%, 2%. 4%, 6% and 8% respectively. Then, the squid inky rice cake was tested in physical function and chromaticity. Rheometer test was also included in this experiment. In physical function test, it showed that the inky rice cake with 6% and 8% ratio was the best in preference. In the chromaticity test, as the adding ratio of squid ink increases, the brightness decreased. The red and yellow brightness of 8% inky rice cake showed high. The results of rheometer test are as follows. In hardness, the inky rice cake with 2% adding ratio was high and the 6% inky rice cake was low. In cohesiveness, the 0% inky rice cake was high and the 8% inky rice cake was low. In gumminess, the 2% inky rice cake was high and the 6% inky rice cake was low. In brittleness, the 2% inky rice cake was high and the 6% inky rice cake was low. With correlation analysis, 1 could reach the following. The overall quality of inky rice cake was correlated with all test items except chewiness. The moistness was correlated with flavor, grain and chewiness. Also, the 8% inky rice cake was correlated with the inky rice cakes with the other adding ratios in all aspects of test.

  • The effects of the substitution of sugar alcohol for sugar on the sensory properties of mulberry rice cake, 'Bbongseolgy', were evaluated in two phases. First, the relative sweetness of xylitol, erythritol and palatinose to the sucrose in the food systems were examined with paired comparison tests. Second, the sensory properties of the mulberry rice cake containing xylitol, erythritol and palatinose substitution for sugar at a sweetness level equal to sucrose were studied. Sensory analysis for the mulberry rice cake characteristics was conducted and consumer acceptability tests were performed. The physical properties of mulberry rice cake were also examined. The relative sweetness of xylitol, erythritol and palatinose, compared to sucrose, in the solid model food system were 1.00, 0.63 and 0.42, respectively. This result showed that the relative sweetness of xylitol, erythritol and palatinose to sugar was slightly lower than those in the liquid model food system, in which flavor did not influence the sweetness. Mulberry rice cake with erythritol or palatinose had very similar characteristics, with lower fracturability and tenderness, and higher moistness, compactness and chewiness compared to that with sucrose or xylitol. Mulberry rice cake with xylitol was significantly the most fracturable, grainy, and driest, and the least adhesive, among the samples. The consumer test showed no difference in overall acceptability among the samples and consumers perceived differences only in moistness, coarseness and compactness among the samples. Mulberry rice cake with erythritol was the most favored in many characteristics. These results indicate that erythritol substitution for sugar inmulberry rice cake is suitable as a low-calorie rice cake with beneficial functions to improve in the health and texture of the rice cake.

  • This study, observing each respectively packaged Kongdduk during 12-day storing period and comparing it with unpackaged Kongdduk, through a cross-sectional view of its fiber and temperament, through a sensory evaluation rheometer measurement of rheological change depending on storing period and packaging type and through the organic acid content, micro-organic change, and retrogressive process. The results are as follows: 1. Kongdduk made of bean oil shows better chewiness, cohesiveness, and moistness than Kongdduk made of bean flour while Kongdduk made of bean flour shows better rheological properties as to roasted nutty taste or roasted nutty order. 2. The test of the cutted loaves of Kongdduk shows that adding oil of proper proportion to the dough of steamed rice cake in accordance with the amount of rice flour has a good influence on rheological properties of softness. 3. Rice cakes were prepared by addition of yellow soybean flour or peanut flour and packaged with CMP or VP, and their physical characteristics were monitored by sensory evaluation and mechanical measurement while storing for 6 days. For VP samples, yellow soybean rice cake showed little changes in cohesiveness, moistness and chewiness for 6 days of storage, while pure rice cake and peanut rice cake showed an increase in strength and hardness from the 4th day of storage. In case of CMP, yellow soybean rice cake hardly showed a difference in cohesiveness, moistness and chewiness for 6 days, while pure rice cake and peanut rice cake showed a significant difference from the 4th day in sensory evaluation. 4. For rheometer measurement, yellow soybean rice cake with CMP or VP showed little changes in strength or hardness for 6 days, while peanut rice cake and pure rice cake showed a drastic decrease in cohesiveness, from the End day and adhesiveness from the 4th day of storage. As there was no remarkable difference or deterioration for 6 days of storage in yellow soybean rice cake between CMP and VP, the ingredients of rice cakeappeared to be more important than the type of packaging in terms of quality deterioration of rice cake. 5. As the storing period passed by, organic acid is detected less at CMP-packaged Knngdduk than at wrapped. and its increasing speed proves to be slower as well. 6. The one wrapped with plyethylene film began to get moldy from pure rice cake or Kongdduk (rice cake mixed with yellow soybean or peanut) after 6 days, and more and more modly after 9 daysor after 12 days, but the CMP-packaged ones didn't get modly until 12 days or more. 7. CMP-packaged Kongdduk showed higher enthalpy of retrogradation than PE-wrapped one. As storing Period Passed by, Kongdduk,s enthalpy grew high. That is to say, it shows that Kongdduk got retrograded.

  • Soybean rice cake, which is often used in Hamkyungdo, is well hewn for a good taste and the slow firiming rate. Since soybean rice cake may taste different according to the amount of ingredients, this study will make a test of the taste and properties of two groups of soybean rice cake. One is prepared from rice flour mixed with yellow soybean and peanut flour at several rate, and the other is prepared from rice flour mixed with oil extracted from yellow soybean and peanut, the containing amount of which is the same as that of oil ingredient contained in each flour. Rice cake prepared mixed with extracted soybean oil shows better characteristics than that which is prepared mixed with soybean flour containing the same amount of oil. The result by sensory test reveals that the element which has a great influence on soybean rice cake is oil. Prepared mixed with extracted oil, soybean rice cake tastes best at 6% of oil, while rice cake prepared mixed with flour instead of oil tastes best at 8% of flour. As this study shows that the relation between firiming rate and oil has a significant influence on cohesiveness, moistness, and chewiness, it is needed to further study the effect of oil according to the kinds of the flour of rice or other grains used.

  • This study investigated the quality characteristics of baked rice cake using dry and wet rice flour. The moisture contents, color values, texture and sensory evaluation(attribute difference and acceptance) for the samples were tested. The moisture content of baked rice cake was the highest in rice cake baked with non- glutinous rice of dry type, and rice cake baked in dry type had weaker brownishness and therefore had higher brightness value compared to the rice cake baked in wet type. In relation to the texture, the hardness was found to be the highest in the rice cake baked with wet non- glutinous rice, and the rice cake baked with glutinous rice was found to be soft. The hardness was the lowest in both wet and dry glutinous rice, and was the highest in the wet non- glutinous rice. Attribute difference test of samples showed that, the rice cake baked with glutinous rice showed clear manifestation of springiness, moistness, adhesiveness, and gumminess (except for the harness). Although the cake baked with dry rice powder showed no significant difference, the dry glutinous rice flour was preferred the most. The rice cake baked with wet glutinous rice flour was preferred the most in terms of flavor, taste, texture, and overall acceptability.
